摘　　要：研究了5种常用杀虫剂(50%吡蚜酮水分散粒剂WG、5%啶虫脒水分散粒剂WG、10%溴氰虫酰胺可分散油悬浮剂OD、10%烯啶虫胺水剂AS和25%阿克泰水分散粒剂WG)及其不同剂量对草莓蚜虫防治效果的影响。结果表明:高剂量的10%烯啶虫胺AS(67.50 g ai∕hm~2)和50%吡蚜酮WG(225.00 g ai∕hm~2)对草莓蚜虫防治速效性较好,2 d防效分别达到93.98%和92.88%。随着施药时间的延长,防效逐渐升高,用药7 d后,除50%吡蚜酮WG(67.50 g ai∕hm~2)和5%啶虫脒WG(6.75 g ai∕hm~2)2个处理外,其他处理的防效均达到85%以上。用药14 d后,25%阿克泰WG(112.50 g ai∕hm~2)、10%烯啶虫胺AS(67.50 g ai∕hm~2)及5%啶虫脒WG(22.50 g ai∕hm~2)处理的防效仍维持在98.36%、98.34%和97.38%;在用药初期,高剂量处理组的防效一般显著高于中、低剂量处理组,用药7 d、14 d后,除5%啶虫脒WG(11.25 g ai∕hm~2、22.50 g ai∕hm~2)外,其他杀虫剂的高、中剂量处理的防效之间已无显著差异。试验中5种常用杀虫剂不同剂量对草莓植株均是安全的,未产生药害。本研究可为上海地区草莓蚜虫防治杀虫剂选择提供参考。The control effects of 5 common insecticides(50% pymetrozine WG,5% acetamiprid WG,10% cyantraniliprole OD,10% nitenpyram AS and 25% thiamethoxam WG) and their different doses on strawberry aphids were studied.The results showed that high dose of 10% nitenpyram AS(67.50 g ai∕hm~2) and 50% pymetrozine WG(225.00 g ai∕hm~2) had good control effects on strawberry aphids,and the control effects reached 93.98% and 92.88% respectively at 2nd day.With the extension of application time,the control effects gradually increased.After 7 days of application,the control effects of other treatments reached more than 85%,except 50% pymetrozine WG(67.50 g ai∕hm~2) and 5% acetamiprid WG(6.75 g ai∕hm~2).After 14 days of application,the control effects of 25% thiamethoxam WG( 112.50 g ai∕hm~2),10% nitenpyram AS(67.50 g ai∕hm~2) and 5% acetamiprid WG(22.50 g ai∕hm~2) remained at 98.36%,98.34% and 97.38%.At the beginning of application,the control effects of high dose treatment group was generally significantly higher than that of the middle and low dose treatment groups.After 7 days and 14 days of application,except for 5% acetamiprid WG(11.25 g ai∕hm~2,22.50 g ai∕hm~2),there was no significant difference between the control effects of the high dose and middle dose treatments of other insecticides.In the experiment,the 5 commonly insecticides with different doses were safe for strawberry plants,and did not cause harm.This study could provide a reference for the selection of insecticides for controlling strawberry aphids in Shanghai.
