摘　　要：为了解农民喷施化学药剂对板栗主要虫害的防治效果,2009年5—10月,在安徽省金寨县油坊店乡选择20棵板栗母树,其中10棵喷施化学药剂,10棵不喷施化学药剂,每7d收集落果,对虫害情况进行调查,最终通过产量调查评估喷施化学药剂对板栗主要虫害的防治效果。结果表明:喷施化学药剂对剪枝象和栗实象有明显的防治效果;喷施化学药剂,对雪片象和蛾类无明显效用。由此可见,喷施化学药剂对部分板栗虫害有较为明显的防治作用,有利于提高板栗产量和单粒质量,但应根据不同虫害的发生规律及特点,适当、适时、适量地使用化学药剂。A survey was conducted to investigate the influences of the chemical pesticide application on insect pests and production of Chinese chestnut in Dabie Mountain across May to October 2009 in Jinzhai County,Anhui Province. Twenty trees were selected totally to survey the insect pest and their effect on fruit yield,and ten of them were treated with chemical pesticide and the others were not. The results showed that the chemical pesticide application significantly affected on M. cumulates and C. davidi. However,less affected on N. castanes and moths. The chemical pesticide application could improve the fruit size and yield by decreasing the insect damage. So the pesticide could be effective in pest control,and we should use it on the basis of analyzing the regularity of different pests.
