墨玉县天然胡杨林春尺蠖飞防试验研究

摘要

In order to effectively control A pocheima cinerarius ,aerial control tests were conducted in Moyu County through monitoring and grasping the optimal control time .By insect survey ,the numbers of 2-year-old larvae of A pocheima cinerarius increase gradually from April 13 ;2-year-old larvae of A pocheima cinerarius constitute 58%of the total number in April 14 ,April 14 being the optimal control period .Using emamectin benzoate to control A pocheima cinerarius ,the reduced rate of insect density reach the peak value (98 .4% ) and the average number are 93 .8% .Emamectin benzoate is a high effective ,rapid ,stable ,and long-lasting biotic pesticide and has significant effect .%为有效防治春尺蠖，首先通过对墨玉县春尺蠖发生期进行监测，在掌握春尺蠖的最佳防治时期的基础上，在墨玉县胡杨林内进行了飞机防治试验。经虫情调查，从4月13日开始二龄幼虫数量逐渐增加，14日二龄幼虫占总虫口数的58％，为最佳防治时期；使用甲氨基阿维菌素苯甲酸盐防治春尺蠖，虫口减退率最高达到98．4％，平均为93．8％。甲氨基阿维菌素苯甲酸盐是一种高效、快速、稳定、持效期长的生物农药，药剂效果明显。
