“…Other studies evaluating the ability of D. hesperus to suppress B. tabaci on greenhouse tomato used repeated low-level releases of prey over a period of several weeks, and initiated releases of both prey and predator at the outset of the trials [9,18]. Calvo et al [9] observed that densities of whitefly nymphs became higher on plants without predators eight weeks after initial releases during a fall experiment, and 12 weeks in a summer experiment.…”

“…Calvo et al [9] observed that densities of whitefly nymphs became higher on plants without predators eight weeks after initial releases during a fall experiment, and 12 weeks in a summer experiment. Calvo et al [18] reported that B. tabaci nymph densities became significantly higher in the absence of D. hesperus only 17 weeks after low level weekly releases of predator and prey. In these trials, Ephestia kuhniella eggs were provided during the first weeks as a supplementary protein source for D. hesperus nymphs, because the prey was assumed to be too scarce to allow D. hesperus nymphs to reach the adult stage [19].…”

“…Bennet et al [22] found that releasing D. hesperus in combination with the parasitoid Encarsia formosa Gahan (Hymenoptera: Aphelinidae) for the management of T. vaporariorum did not enhance suppression of the whitefly. Calvo et al [18] found that releasing Eretmocerus eremicus Rose & Zolnerowich (Hymenoptera: Aphelinidae) with D. hesperus increased suppression of B. tabaci nymphs on greenhouse tomato by only nine percent, 13 weeks after release of biocontrol agents. A future avenue of research could evaluate the compatibility of D. hesperus with biopesticides, including insecticidal soaps, which have demonstrated efficacy against B. tabaci on tomato under greenhouse conditions [23].…”

The sweetpotato whitefly, Bemisia tabaci, is a pest of greenhouse-grown tomato. Restrictions on insecticides in enclosed structures and the presence of commercial pollinators limit the options for the chemical control of whiteflies in greenhouses, increasing the importance of biological controls. Dicyphus hesperus is a zoophytophagous mirid predator native to North America. Three release rates of D. hesperus were evaluated on greenhouse tomato for control of the sweetpotato whitefly. The release rates were one, two or three adult D. hesperus per tomato plant each week for three weeks in cages containing four tomato plants and one mullein banker plant. There were fewer whitefly eggs in cages receiving predators than untreated cages one week after the third release, and fewer whitefly nymphs in cages receiving predators two weeks after the third release. There were no statistical differences in whitefly eggs or nymphs among predator release treatments. The highest release rate resulted in a 60% reduction in whitefly nymphs. Forty-two days after the first predator releases, there were no differences among release treatments in the number of D. hesperus. Our results indicate that D. hesperus can contribute management of B. tabaci on greenhouse tomato, but that it may be insufficient as a sole strategy.

“…Many generalist predators, including coccinellids, chrysopids, anthocorids, geocorids, nabids, mirids, syrphids, and predatory mites, have been reported to feed on potato psyllids in the field (10,93,146) and in the laboratory or greenhouse (3,12,13,35,47,64,70,89,91,92,99,125,151). However, more work is needed to understand the roles of generalist predators in the field.…”

Biology, Ecology, and Management of the Potato Psyllid, Bactericera cockerelli (Hemiptera: Triozidae), and Zebra Chip Disease in Potato

The potato psyllid, Bactericera cockerelli (Šulc) (Hemiptera: Triozidae), transmits the pathogen “ Candidatus liberibacter solanacearum” (Lso), the putative causal agent of zebra chip disease (ZC). ZC is a disease of potato that reduces yield and quality and has disrupted integrated pest management programs in parts of the Americas and New Zealand. Advances in our understanding of the ecological factors that influence ZC epidemiology have been accelerated by the relatively recent identification of Lso and motivated by the steady increase in ZC distribution and the potential for devastating economic losses on a global scale. Management of ZC remains heavily reliant upon insecticides, which is not sustainable from the standpoint of insecticide resistance, nontarget effects on natural enemies, and regulations that may limit such tools. This review synthesizes the literature on potato psyllids and ZC, outlining recent progress, identifying knowledge gaps, and proposing avenues for further research on this important pathosystem of potatoes. Expected final online publication date for the Annual Review of Entomology, Volume 69 is January 2024. Please see http://www.annualreviews.org/page/journal/pubdates for revised estimates.

“…Unfortunately, resistance has developed to some neonicotinoids, including those that are most commonly applied Trumble 2018, Szczepaniec et al 2019). Despite some success using two natural enemy species in greenhouses (Calvo et al 2018), repeated attempts to use biological control to manage tomato psyllid populations on any field crops have not proven commercially effective (Knowlton and Allen 1936, Pletsch 1947, Al-Jabr 1999, Butler and Trumble 2012.…”

Effects of High-Level Acylsugar-Producing Tomato Lines on the Development of Tomato Psyllids (Hemiptera: Triozidae)

Acylsugars have been shown to provide activity against numerous insect pests of tomatoes. Comparison of acylsugar levels in four tomato plant lines, FA7/AS, FA2/AS, CU071026, and ‘Yellow Pear’, found that the acylsugar contents in the elevated acylsugar lines were significantly higher than the commercial Yellow Pear (control) tomato plant line. Adult choice tests indicated that the tomato psyllid, Bactericera cockerelli, preferred to settle on the Yellow Pear and FA2/AS lines over the line with the highest content of acylsugars, FA7/AS, and the parental line, CU071026. The no-choice test demonstrated that adults laid fewer eggs on the high acylsugar tomato lines than on the control tomato line, Yellow Pear. For all high acylsugar lines, the relative growth index of the psyllid was significantly lower compared with the commercial line, indicating a reduced potential for population growth. Although some tomato psyllids completed their life cycle on the high acylsugar tomato plant lines, the percent survival of psyllids to the adult stage when developing on the high acylsugar lines was significantly less (range = 43.7–57.1%) than on the commercial tomato line (83.8%). All mortality occurred during the early stages of development (egg stage to third instar), which has implications for acquisition and transmission of Candidatus Liberibacter solanacearum, the causal agent of tomato vein greening disease. Therefore, with reduced attractiveness for tomato psyllids and significantly reduced survival, the high-acylsugar tomato plant lines have the potential to be part of an integrated pest management program for this pest.
