摘要

摘要：茶尺蠖病毒杀虫剂应在每年茶尺蠖第1、2代和第5、6代的1～2龄幼虫期使用。在7．5×109～ 15．0×109 PIB／hm 的使用剂量下，幼虫期的防治效果可达98％以上。采用不同的喷雾器、不同的用水量及不同的喷施方式喷施，对防治效果无影响。但挑治和丛面喷施可大幅度节约防治成本费。

Abstract

Abstract：Ectropis obliqua nucleopolyhedrovirus(EoNPV)infects tea looper Ectropis obIiqua speci— tically．The application techniques of EoNPV preparations were studied in this paper．It was suggested that the optimum applied periods were 1～ 2 instar larvae of the 1st，the 2nd，the 5th and the 6th generation．The control efect was over 98％ with the usage dose of 75 x 10 150 x 10 PIB／ha． Picking out spraying or surface spraying was more economical，although the amount of dilution water, sprayers，spraying methods did not affect the control efect significantly．
