摘要
对2.0%噻虫啉触破式微胶囊和2.5%高效氯氟氰菊酯对竹卵圆蝽的毒杀效果进行试验,结果表明:2.0%噻虫啉触破式微胶囊水悬剂200倍液和2.5%高效氯氟氰菊酯触破式微胶囊水悬剂200倍液对竹卵圆蝽的毒杀活性均较高,校正死亡率分别达到88.9%和92.8%;施药2、7、30 d后虫口密度最高分别下降了94.3%和93.0%;大田试验结果表明,施药30 d后虫口密度显著下降,下降率分别达90.0%和91.9%。
Experiments were conducted on toxic effect of thiacloprid and lambda-cyhalothrin on Hippotiscus dorsalis in bamboo forests of Anji,Zhejiang province.The results showed that the treatments of 200-fold of 2.0% thiacloprid and 200-fold of 2.5% lambda-cyhalothrin had the highest toxic effect,the corrected mortality reached 88.9% and 92.8%.The insect density after two,seven and thirty days after application decreased 94.3% and 93.0%.The field experiments showed that the insect density 30 days after application decreased respectively 90.0% and 91.9%.
