害虫抗药性现状及其治理策略;一、抗药性与杀虫药剂发展 二、我国害虫抗药性现状及存在的问题 三、我国害虫抗药性治理策略 四、展望 ;一、抗药性与杀虫药剂发展;;;抗药性的百年历史(1908-2014);年 ; 杀虫药剂发展面临害虫抗药性 的严重挑战！;Abstract: One of the significant features of the 20th century has been a massive increase of insect control by chemicals, an exercise in applied entomology and chemistry; another has been the appearance of insecticide-resistance, a consequence of general biological principles. It is typical of the generosity of Americans, who have played so leading a part in the development of the one and in research on the other, that they have chosen a Canadian to describe them in their Memorial Lecture. This honor is taken as a token of the high regard in which entomology in Canada is now held. It also offers the opportunity of paying tribute to J. H. Comstock, who founded the Department of Entomology at Cornell University which has been Mecca to so many Canadian students. ;抗性发展速度超过了新药剂开发速度！;15 ;;化合物;二、我国害虫抗药性现状及存在的问题;Increasing;蔬菜害虫;小菜蛾（ Plutella xylostella ）在我国抗药性情况（1）;小菜蛾（ Plutella xylostella ）在我国抗药性情况（2）;小菜蛾（ Plutella xylostella ）在我国抗药性情况（3）;烟粉虱（ Bemisia tabaci）在我国抗药性情况（1）;烟粉虱（ Bemisia tabaci）在我国抗药性情况（2）;烟粉虱（ Bemisia tabaci）在我国抗药性情况（3）;菜青虫（ Pieris rapae）在我国抗药性情况;萝卜蚜（Lipaphis erysimi ）在我国抗药性情况;温室白粉虱（Trialeurodes vaporariorum）在我国抗药性情况;棉花害虫;棉蚜（ Aphis gossypii）在我国抗药性情况（1）;棉蚜（ Aphis gossypii）在我国抗药性情况（2）;棉铃虫（ Helicoverpa armigera）在我国抗药性情况（1）;棉铃虫（ Helicoverpa armigera）在我国抗药性情况（2）;棉铃虫（ Helicoverpa armigera）在我国抗药性情况（3）;棉铃虫（ Helicoverpa armigera）在我国抗药性情况（4）;棉铃虫（ Helicoverpa armigera）在我国抗药性情况（5）;水稻害虫;褐飞虱（Nilaparvata lugens）在我国抗药性情况;白背飞虱（Sogatella furcifera）在我国抗药性情况;二化螟（Chilo suppressalis）在我国抗药性情况;小麦害虫;麦长管蚜（Macrosiphum avenae）在我国抗药性情况;果树及其他害虫;朱砂叶螨（Tetranychus cinnabarinus）在我国抗药性情况;药剂名称;东方果实蝇（ Bactrocera dorsalis）在我国抗药性情况;苹果蠹蛾（ Cydia pomonella）在我国抗药性情况;椰心叶甲（ Brontispa longissima）在我国抗药性情况;马铃薯叶甲（leptinotarsa decemlineata）在我国抗药性情况;抗性监测存在的问题;三、我国害虫抗药性治理中存在的问题;1. 忽略了有效治理时机-早期;抗性形成三个阶段采取的不同治理策略;2. 忽略了剂量控制的基本原理;抗药性治理的单位剂量原理;3. 抗药性治理的措施-药剂轮用与混用不合理;用作用机制不同的药剂交替使用(轮用)？ 作用机制
