HELP(害迩匍)在温室白粉虱等害虫化学治理中的增效作用

SYNERGISM OF HELP IN THE CHEMICAL CONTROL OF GREENHOUSE WHITEFLY AND OTHER INSECT PESTS

温室白粉虱和棉铃虫是我国蔬菜与棉花生产中的主要害虫，其抗性治理一直是植保工作的重点和难点。该试验利用增效剂ＨＥＬＰ加各种常用杀虫剂，对温室白粉虱、棉铃虫的毒理测定结果证明：ＨＥＬＰ在温室白粉虱的化学治理中有显著的增效作用，在棉铃虫的防治中亦有一定的增效作用。

Greenhouse whitefly (Westwood)]and cotton bollworm Heliothis armigera (Hbner)]are the main pests in vegetable and cotton production. The resistance management of them is the important work in plant protection. In this test the synergist HELP plus some common insecticides are used to control greenhouse whitefly and cotton bollworm. The result shows that HELP has notable synergism in chemical control of greenhouse whitefly. And it has some synergism in control of cotton bollworm, too.
