METHODS FOR GENETIC CONTROL OF INSECT INFESTATIONS IN PLANTS AND COMPOSITIONS THEREOF

The present invention relates to control of pest infestation by inhibiting one or more biological functions. The invention provides methods and compositions for such control， By feeding one or more recombinant double stranded RNA molecules provided by the invention to the pest， a reduction in pest infestation is obtained through suppression of gene expression. The invention is also directed to methods for making transgenic plants that express the double stranded RNA molecules， and to particular combinations of transgenic pesticidal agents for use in protecting plants from pest infestation.

本发明涉及通过抑制一种或多种生物学功能开展虫害防控。本发明提供了用于该类防控的方法与组合物：将本发明提供的一种或多种重组双链核糖核酸（double stranded RNA）分子投喂给害虫，即可通过抑制基因表达实现虫害侵扰程度的降低。本发明同时涵盖制备可表达该双链核糖核酸分子的转基因植物的方法，以及用于保护植物免受虫害的特定转基因杀虫药剂组合。
