摘要
采用释放异色瓢虫和喷施化学药剂2种方法对杏球坚蚧进行了防治对比试验,结果表明:利用异色瓢虫防治杏球坚蚧,虫口减退率为91.28%,防治效果达到92.25%;药剂防治杏球坚蚧防治效果为94.98%.两者之间差异不显著,均具有良好的防治效果。
Didesmococcus koreanus was controled by 2 methods of releasing Harmonia axyridis and spraying chemicals. Results showed that pest decreased rate and control effect of releasing Harmonia axyridis was 91. 28% and 92. 25%,while the control effect of spraying chemicals was 94. 98%. There was no significant difference between these 2 methods and both them had good control.
