Widely grown transgenic crops producing insecticidal proteins from Bacillus thuringiensis (Bt) can benefit agriculture, but adaptation by pests threatens their continued success. Refuges of host plants that do not make Bt toxins can promote survival of susceptible insects and delay evolution of resistance, particularly if resistance is inherited as a recessive trait. However, data have been lac...
This investigation was aimed to study the management of bollworms using different integrated pest management strategies in cotton. Highest infestation in bolls at harvest was recorded in module-5 and lowest was recorded in module-2. Net returns were highest in module-5, which also recorded maximum cost-benefit ratio. Low net returns and cost-benefit ratio were recorded in module-3. Eventhough, ...
Pheromone-baited traps have been widely used for the monitoring of cotton bollworm, Helicoverpa armigera (Hübner) (Lepidoptera: Noctuidae), in order to time any control measures during growing season. Different techniques may provide differential results regarding adult captures. However, studies on comparative evaluation performance different trap types captures H. are limited. To close this g...
Pest insects harm crops, livestock and human health, either directly or by acting as vectors of disease. The Sterile Insect Technique (SIT)--mass-release of sterile insects to mate with, and thereby control, their wild counterparts--has been used successfully for decades to control several pest species, including pink bollworm, a lepidopteran pest of cotton. Although it has been suggested that ...
Potential resistance development to Bt cotton in certain lepidopterans has prompted research to develop strategies that will preserve this environmental-friendly biotechnology. Proteinase inhibitors are potential candidates for enhancing Bt toxicity against lepidopteran pests and for expanding the spectrum of control for other insects. Interactions of Bt toxin from Bacillus thuringiensis and pr...
