The Halo Effect: Suppression of Pink Bollworm on Non-Bt Cotton by Bt Cotton in China
In some previously reported cases, transgenic crops producing insecticidal proteins from Bacillus thuringiensis (Bt) have suppressed insect pests not only in fields planted with such crops, but also regionally on host plants that do not produce Bt toxins. Here we used 16 years of field data to determine if Bt cotton caused this "halo effect" against pink bollworm (Pectinophora gossypiella) in s...
متن کاملArthropod MAnAgeMent evaluation of toxicity of Selected Insecticides against thrips on Cotton in Laboratory Bioassays
Adult vial technique (AVt) and spray table bioassays were conducted to evaluate toxicity of selected insecticides against immature and adult thrips, Frankliniella spp. (thysanoptera: thripidae). In AVt, technical insecticides comprised of organophosphates (dicrotophos and methamidophos), spinosyn (spinosad) and neonicotinoids (thiamethoxam and imidacloprid) were used. the LC50 values for contac...

This study deals with Insecticide Resistance Management of cotton bollworm Helicoverpa armigera to five commonly used insecticides on cotton were carried out during 2008. In August, LD value for 50 chlorpyriphos varies from 0.046μg/larva in Parbhani district to 0.172 mg/larva during October in Aurangabad district. Resistance to chlorpyriphos was highest in Aurangabad district (3.65-8.25 fold) f...

1. Changes in the frequency of Cry1Ac resistance genes and shifts in tolerance of cotton bollworm, Helicoverpa armigera , to the Cry1Ac toxin were assessed using bioassays of F 1 and F 2 offspring of isofemale lines from Anci County of Hebei Province (a multiple-crop system including corn, soybean, peanut, and Bt cotton) and Xiajin County of Shandong Province (an intensive Bt cotton planting ar...
