三种杀虫剂对板栗透翅蛾防治研究

The field Effect of two Insecticides on Controlling?Aegeria molybdoceps Hampson

本试验选用高效氯氟氰菊酯、啶虫脒和氧化乐果对泰安市徂徕山林场内板栗透翅蛾进行防治。结果表明采用注射法施用3%的啶虫脒乳油防治效果最好,施药15天后平均防效为94.7%,40%氧化乐果乳油的平均防效为91.3%,2.5%高效氯氟氰菊酯乳油的平均79.6%;直接涂抹药剂比注射法施药防效略低,三种药剂的平均防效分别为93.1%、89.2%、78%。

This experiment used Cyhalothrin,acetamiptid and omethoate to control Aegeria molybdoceps Hampson in Culai Forestry Centre in Tai＇an,to explore effective control strategy. The results indicated that 3 % acetamiptid EC had the best control effect on Aeg eria molybdoceps Hampson when Injection method were used,and the average control effectiveness is 95.7% and 93.2% respectively after 15 days of treatment, 40% omethoate EC is 91.3% ,2.5% cyhalothrin EC is 79.6%. When used Smear method, the average control effectiveness of this three Insecticides were 93.1% ,89.2 % ,78%.
