摘要
为探索适用于茶园害虫茶角胸叶甲成虫的防治药剂,选用12种药剂采用胃毒触杀联合毒力法对茶角胸叶甲成虫进行室内毒力测定。结果表明,4种化学药剂和3种生物药剂的毒杀效果较好。综合药效、成本及农残的因素,防控茶角胸叶甲优先选用80亿孢子/毫升金龟子绿僵菌和1%苦皮藤素,化学农药中选用24%虫螨腈和4.5%高效氯氰菊酯。
To select effective insecticides for the controlling adult Basilepta melanopus Lefevre,the toxicities of 12 pesticides were tested by the contact and ingestion method.The results showed that 4 kinds of chemical pesticides and 3 kinds of biological pesticides had batter insecticidal effect.Based on the comprehensive efficacy,cost and pesticide residue factors,8 billion spores/mL Metarhizium anisopliae and 1%Celastrus angulatus were recommended,and 24%chlorfenapyr and 4.5%beta-cypermethrin were better among the tested chemical pesticides.
