Abstract:
... Laboratory experiments were conducted using organophosphate-resistant and susceptible strains of greenhouse whitefly, Trialeurodes vaporariorum Westwood, to assess age-specific vital rates in individually-held adults, and development and survival in preadults on three cotton cultivars at 27 ± 1 °C, 50 ± 10% RH, and a photoperiod of 16:8 (L:D). Female whiteflies lived longer than males, with a maxi ...

Abstract:
... The release of Bt cotton varieties genetically modified for increased tolerance to major cotton insect pests provided impetus for the reestablishment of a cotton industry in northern Australia. However, this stimulated concern that the addition of the gene might facilitate an increase in the potential for weediness of genetically modified cultivars in noncropping habitats. Bt and conventional cott ...

Abstract:
... Transgenic cotton has shown great promise for the control of target pest insects; however, frequent outbreaks of nontarget pest mirids has been recorded in recent years in northern China. To test the hypothesis that transgenic cotton contributes to nontarget pest outbreaks, we studied the impact of transgenic Bt cottons (both Bt and Bt + CpTI) on the fitness of nontarget pest Adelphocoris suturali ...

Abstract:
... Plants can have detrimental effects on biological control agents by affecting their prey or host quality. Thus, it is important to understand the tri-trophic interactions between plants, herbivores and natural enemies when implementing biological control programmes. Studies have shown that both morphological and chemical traits of host plants can affect the third trophic level. Cotton plants are k ...

Abstract:
... Atmospheric carbon dioxide concentration is expected to rise in the coming decades. Rising atmospheric CO₂levels may alter plant‐insect‐parasitoid associations due to the indirect effects of CO₂enrichment on phytochemicals important for herbivore and parasitoid nutrition. Tritrophic effects of elevated CO₂on Bt cotton (GK‐12) and non‐transgenic (Simian‐3, or S3) cotton [Gossypium hirsutum L. (Malv ...

Geocoris punctipes (Say) and Orius insidiosus (Say) are generalist predators found in a wide range of crops, including cotton (Gossypium hirsutum L.) and maize (Zea mays L.), where they provide important biological control services by feeding on an array of pests, including eggs and small larvae of caterpillars. A high percentage of cotton and maize in the United States and several other countries ...
