采用实地调查及室内饲养等方法,摸清金华市区悬铃木上星天牛的生活史和生物学特性。采用2.5%溴氰菊酯乳油、3%噻虫啉进行星天牛防治试验,结果表明:以2.5%溴氰菊酯乳油防治的虫情指数为12.1,防治效果为82.4%;以3%噻虫啉防治的虫情指数为11.0,防治效果为84.8%。说明噻虫啉的防治效果略高于2.5%溴氰菊酯乳油,在生产中可在6月中下旬,优先选择噻虫啉,采用树干喷雾的方法杀死星天牛的卵、幼虫和成虫。 Using field surveys and indoor rearing methods, we can find the life history and biological characteristics of Aster beetle in Jinhua City. 2.5% deltamethrin emulsifiable concentrate and 3% thiacloprid were used for the control experiment. The results showed that the control index was 12.1 and the control effect was 82.4% Pest control insect index 11.0, control effect of 84.8%. The control effect of thiacloprid was slightly higher than that of 2.5% deltamethrin. In production, thiacloprid was preferentially selected in the middle and late June, and eggs, larvae and adults of Asteroids were killed by trunk spray .
