Abstract:
... Diamondback moth, Plutella xylostella (L.) is a serious insect pest of vegetables worldwide, and has evolved resistance to various kinds of insecticides. Studies were conducted to determine the baseline toxicity of metaflumizone and the possibility of cross-resistance between metaflumizone and indoxacarb, two sodium channel blocking insecticides (SCBIs), in field populations of P. xylostella from ...

Bemisia tabaci; cotton; cryptic species; cultivars; fecundity; females; gossypol; insect pests; integrated pest management; life history; pest control; population growth; survival rate
Abstract:
... Use of plant secondary metabolic compounds is an important method for insect pest control. In this study, the survival, development, and reproduction of Bemisia tabaci (Gennadius) (Hemiptera: Aleyrodidae) MEAM1 cryptic species were compared over two consecutive generations on three cotton cultivars of different gossypol levels. Both cotton cultivar and generation significantly affected the fitness ...

Abstract:
... The apple maggot, Rhagoletis pomonella (Walsh) (Diptera: Tephritidae), is a serious introduced quarantine pest in the apple (Malus spp.)-growing regions of central Washington and Oregon. In August 2011, seven fly larvae of unknown origin were discovered infesting fruit of an exotic Chinese crabapple, Malus spectabilis (Aiton) Borkhausen, in Kennewick, Benton County, WA. If confirmed, Chinese craba ...

Abstract:
... Fifty-nine sweetpotato cultivars, including 16 heirlooms, 11 near-heirlooms (developed in the 1960s and 1970s), 19 cultivars from the 1980s, and 13 modern varieties (since 1990), were evaluated for resistance to soil insects in field experiments during 2010–2011 at the U.S. Department of Agriculture-Agriculture Research Service, U.S. Vegetable Laboratory (USDA-ARS, USVL), Charleston, SC. These exp ...

Abstract:
... The tools of insect pest management include host plant resistance, biological control, and insecticides and how they are integrated will influence the durability of each. We created a detailed model of the population dynamics and population genetics of the diamondback moth, Plutella xylostella L., and its parasitoid, Diadegma insulare (Cresson), to study long-term pest management in broccoli Brass ...

Abstract:
... The English grain aphid, Sitobion avenae (F.), is a destructive insect pest of wheat. In this study, wheat germplasm was evaluated for resistance and tolerance to English grain aphid infestation. Except for spikelet number/spike, the 1,000-kernel weight, spike weight, grain weight/ spike, and sterile spikelet number/spike of infested plants were all significantly impacted by English grain aphid in ...

Abstract:
... While soybean cultivars with resistance to the soybean aphid (Aphis glycines Matsumura) have been commercially released, the presence of virulent biotypes capable of overcoming plant resistance threatens the durability of host-plant resistance as a stable management tactic. Novel sources of host plant resistance (HPR) are needed to combat rapid biotype evolution. In this study, we screened 1,021 s ...
