项目摘要

In the brown planthopper, Nilaparvata leugens, the phenomenon of negatively corelated cross resistance was found between malathion and fenvalerate. The similar phenomenon was also found between malathion and ethophenprox. In malathion resistant strain, the cuticular penetration of ^<14>C-malathion was found to be redyced and the metabolism of ^<14>C-malathion was found to be enhanced. However, there were no differences in cuticular penetration, metabolism and binding of ^<14>C-fenvalerate to nerve preparation.In the diamondback moth, Plutella xylostella, phenthoate resistance was found to be caused by low cuticular penetration of ^<14>C-phenthoate and reduced sensitivity of acetylcholinesterase to phenthoate-oxon. Inheritance of phenthoate was controled by an incomplete dominant factor. The resistance mechanism of fenvalerate in the diamondback moth was caused by reduced cuticular penetration of ^<14>C-fenvalerate and reduced sensitivity of nervous system to fenvalerate. The inheritance of fenvalerate resistance was considered to be controled by and imcomplete recessive factor.

褐飞虱对马拉硫磷和氰戊菊酯的交互抗性呈负相关。马拉硫磷和醚菊酯也有类似的现象。在马拉硫磷抗性菌株中，~ 1C<14>-马拉硫磷穿透表皮的速度减慢，~ <14>1C-马拉硫磷的代谢增强。小菜<14>蛾对苯硫磷的抗性是由于苯硫磷的低表皮穿透<14>性和乙酰胆碱酯酶对苯硫磷的敏感性降低所致。敌敌畏的遗传受不完全显性遗传控制。小菜蛾对氰戊菊酯的抗药性机制是由于氰戊菊酯的表皮穿透能力降低<14>和神经系统对氰戊菊酯的敏感性降低所致。氰戊菊酯抗性遗传受不完全隐性因素控制。
