Managing Insect Pests of Rice in Africa
(eds M.C.S. Wopereis et al.) 229 In the search for sustainable management options to increase food security, an overall challenge is to increase yields and decrease losses during production and harvest without harming the environment and resource base for future generations of farmers and consumers. As such, integrated pest management (IPM) plays a key role in the context of sustainable agricul...
متن کاملGenetic engineering of rice for resistance to homopteran insect pests
The rice brown planthopper (BPH; Nilaparvata lugens) is a serious pest of rice crops throughout Asia, damaging plants both through its feeding behavior and by acting as a virus vector. Like many homopteran pests of crops, it is primarily a phloem feeder, abstracting sap via specially adapted mouthparts. An artificial diet bioassay system for this pest was developed to allow the effects of poten...
متن کاملImpact of insect-resistant transgenic rice on target insect pests and non-target arthropods in China
Progress on the research and development of insect-resistant transgenic rice, especially expressing insecticidal proteins from Bacillus thuringiensis (Bt), in China has been rapid in recent years. A number of insect-resistant transgenic rice lines/varieties have passed restricted and enlarged field testing, and several have been approved for productive testing since 2002 in China, although none...
متن کاملExpression of Cry1Ab and Cry2Ab by a Polycistronic Transgene with a Self-Cleavage Peptide in Rice
Insect resistance to Bacillus thuringiensis (Bt) crystal protein is a major threat to the long-term use of transgenic Bt crops. Gene stacking is a readily deployable strategy to delay the development of insect resistance while it may also broaden insecticidal spectrum. Here, we report the creation of transgenic rice expressing discrete Cry1Ab and Cry2Ab simultaneously from a single expression c...
متن کاملNovel Genes for Control and Deterrence of Sucking Insect Pests
Current GM crops are thus far the almost exclusive domain of herbicide and insect resistance traits. The Bt toxins used for insect control have a narrow specificity against lepidopteran and coleopteran pests only. Yet, aphids and thrips are highly important pests worldwide, causing severe direct losses and transmitting devastating viruses such as Tomato Spotted Wilt Virus (TSWV). So far, few us...
