Abstract:
... Little is known on the resistance of wheat cultivars to Sitobion avenae (F.) in Brazil. The goal of this work was to assess the behavior and biology of S. avenae on four commercial wheat cultivars to verify the existence of resistance by antibiosis in leaves and ears and non-preference in the ears. The smallest net fecundity rates of S. avenae in wheat leaves have been found in the cultivars Embra ...

Abstract:
... To assess the ecological effects of Bt-cotton cultivars (ZMSJ and ZMKCKC, expressing Cry1Ac/Cry2Ab and Cry1Ac/EPSPS, respectively), laboratory experiments were performed to evaluate the transmission of Cry1Ac protein in the food chain and the effects of Bt toxin on the ladybeetle predator Propylaea japonica through its herbivorous prey Aphis gossypii. Trace amounts of Cry1Ac protein (3.0ng/g fresh ...

Abstract:
... The results showed that age specific fecundity and survival rates of aphid were significantly lower on Ethiopian mustard, while intrinsic rates of natural increase and mean relative growth did not differ significantly among brassica cultivars but numerically lower on both kale and rape. A significant delay in pre-reproductive period was observed on rape variety compared to other brassicas. The dif ...

Abstract:
... Use of plant secondary metabolic compounds is an important method for insect pest control. In this study, the survival, development, and reproduction of Bemisia tabaci (Gennadius) (Hemiptera: Aleyrodidae) MEAM1 cryptic species were compared over two consecutive generations on three cotton cultivars of different gossypol levels. Both cotton cultivar and generation significantly affected the fitness ...

Abstract:
... Transgenic Cry1Ac, Cry2Aa and Cry1Ca (Bt toxins) rice lines are well developed to manage lepidopteron pests in China. The impact of transgenic Bt rice on the non-target Brown Planthopper (BPH) has become an essential part of environmental risk assessment, however, scanty evidence is found addressing on developmental and molecular responses of BPH to the ingestion of Bt protein from transgenic rice ...
