摘要
Bacillus thuringiensis is a major microbial insecticide and a source of genes encoding several proteins toxic to insects. In this paper the authors g ive a brief summary of Bacillus thuringiensis used on the integrated pest manage ment in forestry. The derivatives of Bt strain HD1 subsp kurstaki have been wide ly used to control the forest pests such as the gypsy moth (Lymantria dispar), s pruce budworm (Choristoneura fumiferana), the pine processionary moth (Thaumetop oea pityocampa), the European pine shoot moth (Rhyacionia buoliana) and the nun moth (Lymantria monacha). Some progresses of transferring and expressing Bt toxi n gene in forest trees are offered with a discussion on the limits and future pr ospects of using Bt products in forestry.
苏云金杆菌是一种重要的微生物杀虫剂，而且能够编码几种昆虫毒蛋白基因。本文概述 了苏云金杆菌在森林害虫综合治理中的应用。苏云金杆菌HD1菌株及其衍生物被广泛用于防 治各种森林害虫，如Lymantria dispar, Choristoneura fumiferana, Thaumetopoea pityo campa, Rhyacionia buoliana和Lymantria monacha。文章提供了Bt毒蛋白基因在林木中的 构建和表达方面的研究进展并对Bt产品在森林害虫综合治理上的应用前景及限制因素进行了 初步讨论。
