梨小食心虫发生期预测与防治

摘要

于2014-2016年利用性诱剂诱蛾,调查了桃、梨蛀果类害虫梨小食心虫发生量,预测了其在桃树上的发生期,并研究了几种药剂对梨小食心虫的防治效果.结果表明,20％氯虫苯甲酰胺(康宽)SC 3 000倍稀释液、15％茚虫威(凯恩)EC 2 000倍稀释液、6％阿维·氯苯酰(宝剑)SC 750倍稀释液、10％阿维·氟虫双酰胺(稻腾)SC 1 000倍稀释液对梨小食心虫的防效较好,在90％左右.并提出了蛀果类害虫的综合防治技术.%We investigated the occurrence quantity of Grapholitha molesta (Busck) in peach trees and pear trees by sex lures trapping method from 2014 to 2016,and studied the control effects of several agents against Grapholitha molesta (Busck).Results showed that 3 000 times of 20％ chlorantraniliprole SC liquid,2 000 times of 15％ indoxacarb EC liquid,750 times of 6％ abamectin · chlorantraniliprole SC liquid and 1 000 times of 10％ abamectin · flubendiamide SC liquid had good control effect on Grapholitha molesta (Busck),about 90％.Some integrated prevention and control technique for decay fruit pests were put forward.
