  Abstract: Bagrada hilaris Burmeister is an invasive species native to the old world and is currently threatening commercial vegetable production in the southwestern USA. A series of no-choice experiments were conducted to investigate multiple plant responses in six Brassica crops to feeding by B. hilaris. Varying numbers of adults were caged onto cotyledon, 2-true leaf, and 4-true leaf-stage plants of broccoli, green cabbage, red cabbage, cauliflower, kale, and radish for a 48-h infestation period. Feeding damage on leaf surfaces, total leaf area, and relative chlorophyll content on plants of each crop were measured before and after the 48-h infestation period. In addition, dry weights and total leaf area for the 4-leaf-stage plants were measured at 21 days post-infestation to estimate the residual impacts on older plants. In all crops tested, feeding damage increased with greater numbers of B. hilaris adults caged on cotyledon and 2-leaf-stage plants. Significantly more feeding damage occurred on the upper (younger) two leaves than on the lower (older) two leaves of the 4-true leaf plants for all host plants suggesting that B. hilaris feeds preferentially on newer leaf tissue. Significant reductions in leaf area, relative chlorophyll content, and dry weight in all crops indicated negative impacts on plant growth by B. hilaris. Moreover, cotyledon and 2-leaf plants were more severely impacted by B. hilaris-induced injury than the 4-leaf plants, and kale appeared to be less sensitive to B. hilaris feeding than the other five Brassicaceous hosts. © 2014 The Author(s).

  Abstract: A series of host-choice tests were conducted under greenhouse conditions to evaluate the host selection behavior of the Bagrada bug, Bagrada hilaris on commercial cruciferous seedlings. In addition, a separate choice test was conducted to investigate the selection behavior of B. hilaris adults for broccoli plants of various growth stages: cotyledon, 1-leaf, 2-leaf, and 4-leaf plant stages. In comparing host selection among the commercial seedlings, observations on host attractiveness, host acceptance and host susceptibility of the cruciferous cultivars to B.hilaris adults were measured by recording numbers of adults per plant, the time at which feeding damage was first observed, and the time plant mortality occurred for each cultivar, respectively. Results showed that significantly more adult B.hilaris were attracted to a commercial radish cultivar than all other hosts, followed by red and green cabbage. Measurements of host acceptance varied among the cruciferous cultivars, however in terms of feeding damage, alyssum, arugula and broccoli appeared to be relatively less acceptable hosts for B.hilaris. Similarly, all host plants were susceptible to B.hilaris feeding damage and plant mortality varied among cultivars. In the broccoli growth-stage trials, experiments were designed in a similar fashion except that the experiment was conducted in plastic cages. A greater number of B.hilaris adults were attracted to 4-leaf-stage broccoli than other growth stages, but feeding damage was observed more quickly on cotyledon-stage plants. The implications of these findings for developing alternative pest management approaches for B.hilaris in commercial cruciferous crops are discussed. © 2014 The Authors.

  PMID: 24020287;Abstract: Patterns of diel activity and behavior of the Bagrada bug, Bagrada hilaris (Burmeister) (Hemiptera: Pentatomidae), were investigated in a series of field and greenhouse experiments in Yuma, AZ. Adults of B. hilaris were monitored by on-site direct observation on broccoli and cauliflower plants in large-block experimental plots at various intervals throughout consecutive 24-h periods. In the field trials, mean number of B. hilaris adults differed among sampling times, with peak abundance observed consistently between 1300 and 1800 hours. There was a positive correlation between temperature and numbers of B. hilaris adults in all fields, and a negative relationship between humidity and adult numbers in 7 of 12 fields. Significant relationships between temperature and B. hilaris numbers were revealed in regression models for all trials. Slopes were not significantly different among all broccoli blocks or in three of the four cauliflower fields. In greenhouse studies, mating occurred throughout the day but peaked between 1000 and 1600 hours. Females of B. hilaris caused more feeding damage than males on the first true leaf of broccoli, and additional differences in behavior between sexes were observed. Our results suggest that higher temperatures increase field activity and influence the behavior of adult B. hilaris, and temperature is a more reliable indicator to predict the activity of B. hilaris than other environmental parameters measured. The implications of these findings for developing monitoring and management programs for B. hilaris in cruciferous crops are discussed. © 2013 Entomological Society of America.

  PMID: 19152818;Abstract: Effective management of insect and mite vectors of plant pathogens is of crucial importance to minimize vector-borne diseases in crops. Pesticides play an important role in managing vector populations by reducing the number of individuals that can acquire and transmit a virus, thereby potentially lowering disease incidence. Certain insecticides exhibit properties other than lethal toxicity that affect feeding behaviours or otherwise interfere with virus transmission. To evaluate the potential of various treatments against the Bemisia tabaci-transmitted Cucurbit yellow stunting disorder virus (CYSDV), insecticide field trials were conducted in Yuma, AZ, USA, during spring and autumn growing seasons. Differences in vector-intensity each season led to mixed results, but at least five insecticide treatments showed promise in limiting virus spread during spring 2008. Increasing concern among growers in this region regarding recent epidemics of CYSDV is leading to more intensive use of insecticides that threatens to erupt into unmanageable resistance. Sustainability of insecticides is an important goal of pest management and more specifically resistance management, especially for some of the most notorious vector species such as B. tabaci and Myzus persiscae that are likely to develop resistance.

  PMID: 19842090;Abstract: In the 'Integrated Control Concept', Stern et al. emphasized that, although insecticides are necessary for agricultural production, they should only be used as a last resort and as a complement to biological control. They argued that selective insecticide use should only be attempted after it has been determined that insect control with naturally occurring biotic agents is not capable of preventing economic damage. However, they concluded their seminal paper by emphasizing that integrated control will not work where natural enemies are inadequate or where economic thresholds are too low to rely on biological control. Thus, it is no surprise that insect control in high-value, fresh-market lettuce crops grown in the desert southwest have relied almost exclusively on insecticides to control a complex of mobile, polyphagous pests. Because lettuce and leafy greens are short-season annual crops with little or no tolerance for insect damage or contamination, biological control is generally considered unacceptable. High expectations from consumers for aesthetically appealing produce free of pesticide residues further forces vegetable growers to use chemical control tactics that are not only effective but safe. Consequently, scientists have been developing integrated pest management (IPM) programs for lettuce that are aimed at reducing the economic, occupational and dietary risks associated with chemical controls of the past. Most of these programs have drawn upon the integrated control concept and promote the importance of understanding the agroecosystem, and the need to sample for pest status and use action thresholds forcost-effective insect control. More recently, pest management programs have implemented newly developed, reduced-risk chemistries that are selectively efficacious against key pests. This paper discusses the influence that the integrated control concept, relative to zero-tolerance market standards and other constraints, has had on the adoption of pest management in desert lettuce crops. © 2009 Society of Chemical Industry.

  PMID: 17598296;Abstract: Various insecticide use strategies including rotations, sequential use, and mixtures were evaluated experimentally on Bemisia tabaci (Gennadius) in California and Arizona (USA) cotton fields. Toxicological responses of adult B. tabaci were measured along with preimaginal densities and cotton yields from plots subjected to different insecticide regimens. Weekly monitoring for susceptibility changes over ten consecutive weeks in four different trials failed to detect significant differences between sequential use and rotation regimens, nor in comparison to the control plots. There were, however, significant differences among study-site locations and between study years as well as significant within-season time effects. Relative infestations in insecticide-treated plots expressed as a percentage of preimaginal densities in control plots indicated that better control was obtained by all insecticide treatments in conjunction with higher susceptibility levels observed in the second year. Lower preimaginal densities of B. tabaci were measured in the rotation treatment in comparison to sequential treatments of endosulfan, chlorpyrifos, or amitraz, but all were less effective than sequential treatments of bifenthrin or the mixture of bifenthrin + endosulfan. Cotton lint yields were inversely related to B. tabaci densities, with highest yields in the bifenthrin and mixture plots and lowest yields in the control plots. Suppression of B. tabaci infestations in insecticide-treated plots relative to untreated control plots also improved under conditions of lower B. tabaci pressure. The increases in cotton yield and susceptibility to insecticides seen in the current study support the trend observed in the southwestern USA of improved management of B. tabaci despite continuing intensive use of insecticides.

  Abstract: Historically, Bemisia tabaci has been difficult to control with conventional insecticides in agronomic and horticultural production systems. In the past 10 years, new insecticide chemistries have been introduced that provide a diversity of novel modes of action and routes of activity to effectively control whiteflies. The chemistries that have had the most immediate impact on B. tabaci control include the nicotinoids and insect growth regulators (IGRs). The nicotinoids are systemic neurotoxins that target acetylcholine receptors in the insect nervous system. Imidacloprid, the first nicotinoid registered, has been largely responsible for the sustained management of B. tabaci in horticultural production systems worldwide. The non-neurotoxic IGRs, including buprofezin, a chitin synthesis inhibitor, and pyriproxyfen, a juvenile hormone analog, have also played important roles in controlling B. tabaci, particularly on cotton in North America and Israel. Collectively, the novel biochemical attributes and biological activities of these insecticides make them extremely effective. Consequently, intensive use of these products in some production systems has resulted in reduced susceptibility of B. tabaci.

  PMID: 11142299;Abstract: A 3-yr project was initiated in 1993 to examine the effects of insecticides and sustained whitefly, Bemisia argentifolii Bellows & Perring [aka. B. tabaci Gennadius (Strain B)], feeding on alfalfa plant growth and vigor in greenhouse cage studies, and to determine the impact of natural Bemisia whitefly populations on alfalfa forage yields and quality in a large-plot field experiment. Alfalfa plant growth and vigor after exposure to imidacloprid and a mixture of fenpropathrin and acephale insecticides did not differ from untreated plants in the greenhouse. Consequently, foliar and soil applied insecticides were used to manipulate whitefly densities on alfalfa plants to measure whitefly feeding effects on plant growth and forage yield. Heavy whitefly densities on untreated alfalfa plants in the greenhouse resulted in significant reductions in relative growth rates and net assimilation rates as compared with imidacloprid-treated plants that were maintained relatively whitefly-free. Reductions in alfalfa plant growth measured between infested and treated plants were proportional to whitefly densities. Field plot results derived from three crop seasons were relatively consistent with our greenhouse trials. Both experimental approaches clearly showed that alfalfa plants exposed to high densities of whitefly immatures and adults grew at a significantly slower rate and produced less foliage. As a result of reduced growth rates, alfalfa maturity in the naturally infested plots was estimated to be ≈7-10 d behind managed plots. Delays in maturity resulted in significant reductions in forage yields of 13-18% during August-September harvests when whitefly populations reached peak abundance. Whitefly feeding stresses also effected hay quality through the reduction of crude protein content and contamination of foliage with honeydew and sooty mold. The status of the Bemisia whiteflies as an economic pest to alfalfa is clearly evident from these studies, but the damage potential of whiteflies in the southwestern United States appears to be restricted to one or two harvest periods during the summer coinciding with peak adult populations and their dispersal from alternate host crops. © 2000 Entomological Society of America.

  Abstract: Field populations of green peach aphid, Myzus persicae (Sulzer), were collected from five produce fields near Yuma, Arizona. Three of the fields sampled contained both red and green-colored forms, while the remaining two fields contained only green-colored green peach aphids. Red-colored aphids were consistently more resistant to dimethoate and lambda-cyhalothrin, and usually more resistant to endosulfan than green-colored aphids collected from the same field. Slight differences in susceptibility to imidacloprid suggest that development of resistance is a possibility and justifies close resistance monitoring. Susceptibility to imidacloprid was not influenced by color form. We detected little or no differences in susceptibility to acephate, mevinphos or bifenthrin.

  Abstract: Beet armyworms, Spodoptera exigua (Hübner), were collected from spinach, Spinacia oleracea L., lettuce, Lactuca sativa L., cantaloupe, Cucumis melo L., and alfalfa, Medicago sativa L., and their F1 progeny were evaluated for resistance to methomyl and thiodicarb. No resistance or high levels of resistance were detected to methomyl by using a topical bioassay. Agricultural areas containing a large hectarage of produce crops where methomyl is extensively used throughout most of the year primarily yielded the highest levels of resistance. The highest level of resistance detected came from a strain collected in Imperial County, CA, having a resistance ratio of 552-fold. Low levels of resistance were primarily associated with areas with a small hectarage of produce crops. Detection of high levels of methomyl resistance represents a dramatic shift in susceptibility since 1989. Beet armyworms collected from alfalfa before and after an insecticide application containing methomyl exhibited 101-fold and 450-fold resistance, respectively, suggesting selection for resistance. Beet armyworm strains resistant to methomyl were found cross-resistant to thiodicarb when using a diet incorporation bioassay. However, resistance ratios for thiodicarb never exceeded 5-fold. Similarly, when methomyl was bioassayed using a diet incorporation technique resistance ratios never exceeded 5-fold suggesting that the diet incorporation bioassay may underestimate the severity of resistance or that methomyl resistance may involve cuticular penetration.

  Abstract: Five sprayers were tested to assess deposition efficiency, whitefly control, cantaloupe yield, and off-target movement. These were: an Electrostatic Spraying Systems sprayer (with the charging circuit on and off), a Micromax CDA without air assist, a DeGanya (FMC) with air assist, and a conventional twin nozzle system. The ESS-on and FMC had the highest deposition efficiency on the leaf undersides, and the conventional the lowest. Deposition on the leaf undersides decreased as the canopy closed, with the FMC showing lesser decreases than the ESS systems. For the first two application dates, the ESS-on and ESS-off were associated with greater insect control than the CDA or conventional systems. Later in the season no differences were detected. Overall, cantaloupe yields were not significantly different than for the untreated control. The ESS systems, however, were associated with significantly greater yield of no. 12 cantaloupes than the untreated control. Off-target movement was significantly greater for the FMC than any other system, except the conventional.

  Abstract: The whitefly Bemisia argentifolii Bellows & Perring has been a major pest of crops in the southwestern United States since 1991. However, there has been no published information on whitefly populations on alfalfa, Medicago sativa L., a major crop found through-out this region. In this study, adult and immature Bemisia argentifolii were collected every 2 or 4 wk in 22 commercial fields of alfalfa within localized sites in the Imperial Valley, CA, and in Yuma, AZ, from June 1993 to January 1996. Populations of all stages of whiteflies on alfalfa were low or nonexistent from December to May at both sites. In the Imperial Valley, adult populations increased in June and peaked during September, and decreased from October to November. In Yuma, adult populations peaked during August, and decreased late October to November. Populations of eggs, 1st to 4th instars, late 4th instars, and exuviae at both sites increased in June, July, and August. Compared with densities of eggs and nymphs, densities of exuviae were low on alfalfa. In the Imperial Valley, adult populations were significantly higher in 1993 than in 1995, and in Yuma, adult populations were higher in 1993 than 1994. Greater populations of whiteflies were found in Imperial Valley than in Yuma in 1993 and 1994. Densities of whiteflies of all stages were similar among fields within sites during the season. Eggs were distributed evenly among leaves from top, middle, and bottom strata of plants, whereas nymphs were found mostly on those from the middle and bottom strata. Low percentages of parasitized whitefly nymphs (

  More info

  Abstract: Laboratory populations of the sweet potato whitefly, Bemisia tabaci, have been shown to consist of both migratory and trivial flying morphs. The behavior of these forms as part of the process of short-range migration was examined under field conditions. Insects were marked in a field of melons using fluorescent dust during two consecutive growing seasons. During the first growing season, passive traps used to collect living whiteflies, were placed along 16 equally spaced transects radiating from the field to a distance of up to 1.0 km. Wind out of the north-east consistently carried migrating whiteflies to traps placed along transects in the southwestern quadrant because cold air drainages dictate wind direction during early morning hours in the desert Southwest. For this reason, during the second season traps were laid out over fallow ground in a rectangular grid extending 2.7 km to the south-west of the marked field. If dispersal was entirely passive, patterns could be described using a diffusion model. Statistical examination of the data, however, demonstrated that the distribution on all days was patchy. Geostatistical techniques were used to describe the observed patchiness. Traps in the immediate vicinity of the marked field caught more whiteflies than the daily median. Large numbers were also collected from near the periphery of the grid. Whiteflies were far less prevalent in the grid's center. As a result, the distribution of captured whiteflies can be described as bimodal. These patterns confirm behavior observed in the laboratory, i.e., a portion of the population are trivial fliers that do not engage in migration and are consequently captured in traps near the field, and a portion initially respond to cues associated with skylight, ignoring cues provided by the ground, and fly for a period of time before landing in distant traps. During both years movement out of the field had an exaggerated directional component on 13 of 14 days.

  Abstract: Imidacloprid transplant drench root plug treatments of cauliflower and imidacloprid treatments proplant in-furrow soil injections were evaluated for their effects on colonization of silverleaf whitefly, Bemisia argentifolii Bellows and Perring, green peach aphid, Myzus persicae (Sulzer), and cabbage aphid, Brevicoryne brassicae (Linnaeus). Whitefly treatments included imidacloprid root plug treatments of 180, 270, and 360 g AI/ha, an in-furrow treatment of 360 g AI/ha, and an untreated control. Aphid treatments included imidacloprid root plug treatments of 90, 180, and 270 g AI/ha, an in-furrow treatment of 360 g AI/ha, and an untreated control. The untreated control plants had significantly greater numbers of apterous aphids and whitefly nymphs than imidacloprid treatments. The imidacloprid in-furrow treatment had significantly fewer whitefly immatures than other treatments on several sampling dates. Phytotoxicity evaluations revealed some leaf tissue necrosis from root plug treatments of imidacloprid during the fall planting. Plant growth was re retarded, harvest was delayed, and yield of kg of marketable heads was lower for the untreated control cauliflower plants due to higher whitefly infestation. Reduced yields due to aphids was not observed in the fall planting.

  Abstract: Pyrethroid and endosulfan mixtures applied at full and reduced rates with 3 application methods (air-assisted electrostatic, air-assisted hydraulic, and standard hydraulic sprayers) were evaluated in field studies in 1992 and 1993 for control of sweetpotato whitefly, Bemisia tabaci strain B (Gennadius), also known as silverleaf whitefly, Bemisia argentifolii Bellows and Perring, and spray deposition on cauliflower. Brassiva oleracea L. Evaluations of sweetpotato whitefly control were based on adult suppression, immature colonization, and cauliflower harvests. Spray deposition and coverage on abaxial and adaxial leaf surfaces was measured with a leaf wash technique and water sensitive cards placed on leaves near the terminal and base of plants. Depending on how control was assessed, the air-assisted electrostatic application technique did not consistently improve sweetpotato control when compared with hydraulic application equipment. Based on adult suppression, improved control of whiteflies was achieved with full and reduced rates of the air-assisted electrostatic sprayer following 2 applications in 1992, but percentage of reduction of adults did not differ significantly among the application methods when full rates of insecticide were applied in 1993. Control based on immature colonization indicated that the air-assisted electrostatic sprayer was the only spray method to reduce significantly nymph densities when compared with the control in 1992, but differences in numbers of eggs, nymphs, and enclosed pupal cases varied among application methods and rates of active ingredient in 1993. Comparisons of cauliflower harvest dates indicated that the air-assisted electrostatic sprayer did not provide significantly better control than the other application methods when used at similar rates. Spray deposition with the air-assisted electrostatic application technique was variable throughout these studies with no clear trends being observed. Our results suggest the air-assisted electrostatic sprayer may offer a means to control sweetpotato whitefly with a 50% reduction in insecticide usage.

  Abstract: We used regression diagnostics to evaluate the robustness of the least-squares regression method for estimating the power law and patchiness regression parameters for 3 data sets of insect counts, specifically for the Bemisia argentifolii Bellows and Perring and the squash bug, Anasa tristis (De Geer). Extreme values in the independent variable, x, and dependent variable, y, were detected with the leverage term, h(i), and standardized residuals, e(s) respectively. The assumption of homogeneity of variances was evaluated with plots of e(s) against x for all regressions, and significant autocorrelations were tested with the Durbin-Watson statistic. For both techniques, we compared least-squares regression results for all data with regressions obtained after outlier data points were removed. We also calculated power law regressions excluding means (m)

  Abstract: We measured the effect of insecticide applications on the distribution patterns of the sweet potato whitefly, Bemisia tabaci (Gennadius), in fields of cantaloupe, Cucumis melo L., in Yuma, Arizona. Whitefly infestations were measured by counts of adults, eggs, first to mid/fourth instars, and late-fourth instars ('red-eyed') nymphs. Adults were sampled from the entire leaf, and immature stages were counted in a 1-cm2 area of a leaf. The indices b (Power Law), β (Patchiness regression) and Id (Morisita) indicated that all life stages were aggregated, but results for the three indices were not similar for determining the relative aggregation levels between treatments. In general, indices β and Id indicated higher aggregation in insecticide-treated fields, whereas b had mixed results. The Morisita index was sensitive to a few unusually high means among a series of low densities in the treatment plots, what could be attributed to refuges due to failure in the insecticide applications. Despite the usefulness of the Power Law and the Patchiness regression for describing the relationship between spatial or temporal variability and mean densities, we suggest that Id is more appropriate for expression of spatial distribution because it is based on a precise definition of aggregation. © 1994 Kluwer Academic Publishers.

  Abstract: Early season infestations of the sweet potato whitefly, Bemisia tabaci (Gennadius), on cantaloupes, Cucumis melo L., were determined by counts of the number of adults per leaf in fields near Yuma, Arizona. We used these data to develop binomial sampling plans based on the relationship between mean densities of whiteflies per leaf, m, and proportion of leaves infested with more than I whiteflies, P I, according to the empirical model ln m=a′+b′ ln[-ln(1-P I)]. The models were developed for the presence-absence approach (I=0) and for a cutoff value of three whiteflies per leaf (I=3). Four independent data sets were used to evaluate the models. Both methods yielded reliable predictions at low infestation levels, but some of the higher m values were overestimated. As the tentative economic threshold for B. tabaci is three adults per leaf, which corresponds to low P I values, results of the binomial sampling were satisfactory for pest management purposes. © 1994 Society of Population Ecology.
