葡萄透翅蛾1年只发生1代,且蛾、卵、初孵幼虫发生期高度集中,采用放过成虫,放任前期幼虫蛀入嫩梢,再在蛀往粗枝以前一举施药毒杀的策略,在孵化高峰适时喷施20％三唑磷乳油剂1000～2000倍水稀释液。结果表明,对药前12d内孵化已蛀干的幼虫杀虫率为90％～100％。对药后12d内已蛀干的幼虫杀虫率为87.5％～100％。1次施药就能有效防治葡萄透翅蛾为害。 Grapevine moth only occurs one year in one year, and the moths, eggs and newly hatched larvae are highly concentrated in the occurrence stage. By letting off the adult larvae and letting the larvae invade the young shoots, they are poisoned in one go Strategy, timely spraying hatch peak 20% triazophos emulsion 1000 to 2000 times the water dilution. The results showed that the insecticidal rate of larvae that had been hatched in 12 days before drug treatment was 90% -100%. The insecticidal rate of larvae that had been dried for 12 days was 87.5% ~ 100%. 1 application can effectively prevent grape pest moth damage.
