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...

Laboratory-selected Bacillus thuringiensis-resistant colonies are important tools for elucidating B. thuringiensis resistance mechanisms. However, cotton bollworm, Helicoverpa zea, a target pest of transgenic corn and cotton expressing B. thuringiensis Cry1Ac (Bt corn and cotton), has proven difficult to select for stable resistance. Two populations of H. zea (AR and MR), resistant to the B. th...

Abstract After genetically engineered Bt cotton lost its effectiveness in central and southern Indian states, pink bollworm infestations have recently returned to farmers’ fields substantially shifted their vulnerability context. We conceive as a neoliberal technology that is built protect farmers only temporarily from Lepidopteran pests while ultimately driving the further concentration of cap...

The cotton bollworm, Helicoverpa armigera (Hübner) (Lepidoptera: Noctuidae) is a commonly known polyphagous pest in agricultural areas all over the world. It has been major causing significant damages by reducing tomato fruit production and quality since 1913 Turkey. objective of study was to evaluate genetic diversity phylogenetic relationship H. based on mitochondrial COI gene. Infested tomat...

India ranks second in the global cotton balance, next only China. Cotton is mainstay of India’s textile industry, accounting for roughly 74% total mill usage. production has increased due to introduction and rapid geographical expansion bollworm resistant Bt cotton. The objective this paper compare balance analyses investigate factors that have influenced development over last 22 years. pertine...

The idea of enhanced methanol production from cell wall by pectin methyl esterase enzymes (PME) combined with expression cry genes Bacillus thuringiensis as a strategy to improve insect pest control in cotton is presented. We constructed cassette containing two (cry1Fa and Cry32Aa) pme genes, one Arabidopsis thaliana (AtPME), other Aspergillus. niger (AnPME) pCAMBIA1301 plant vector using CAMV-...
