Larvae in treatment 1 were fed A. gossypii individuals reared on a diet of NuOPAL (Bt) cotton leaves. After treatment with biological insecticide, the mean of increasing rate of aphids was at around recorded at around 0.21 while at around 0.24 in non-treated TBI-1 biological insecticide condition during 1 week. 0000018789 00000 n The biological pest control agent, B. bassiana, showed somewhat insecticidal activities against the cotton aphid, Aphis gossypii, too. 0000252323 00000 n <]/Prev 289086/XRefStm 2091>> In a study in India, with F. pallidoroseum applied against A. craccivora on cowpea, yield at 32 days after treatment showed that an increase in spore concentration resulted in a corresponding decrease in aphid population ... A. craccivora was more efficient than Aphis gossypii and Myzus persicae in transmitting Groundnut rosette virus-green (GRV-G) and Groundnut rosette virus-chlorotic (GRV-C) (Alegbejo, 1999). Aphis gossypii (Glover) is distributed worldwide and causes substantial economic and ecological problems owing to its rapid reproduction and high pesticide resistance. Aphids, mainly A. gossypii, were more numerous on plants in treatment, compared with control, plots in all cases. Cotton aphid, Aphis gossypii Glover (Homoptera: Aphididae), is one of the most injurious insect pests which suck the cell sap and considered one of the cotton yield limiting factors (Fondren et al., 2004).Aphids damage is due not only to its direct feeding, but also to honeydew production during boll set resulting in sticky cotton that can decrease cotton lint quality (Carter, … Plant varieties expressing the Bt (Bacillus thuringiensis) insecticidal proteins Cry1Ah and Cry2Ab have potential commercialization prospects in China.However, their potential effects on non-target arthropods (NTAs) remain uncharacterized. 0000001672 00000 n The cosmopolitan pest Aphis gossypii (Glover) causes considerable economic losses on various crops by its feeding damage and transmitting diseases around the world.
