采用不同温度和不同剂量的磷化铝 ,在不同的处理时间下对四纹豆象的高温灭虫及磷化铝熏蒸的试验 ,结果表明 :四纹豆象蛹的耐高温能力最强 ,卵次之。在 55℃温度下幼虫和成虫经 60min校正死亡率为 1 0 0 % ,蛹和卵要 75min ;在 60℃温度下卵、幼虫、成虫经 1 5min全部死亡 ,而蛹需要 45min才达到 1 0 0 %的死亡率。用磷化铝熏蒸 ,幼虫和成虫较敏感 ,用1 .5g/m3 处理 3天 ,全部死亡 ,但卵、蛹的校正死亡率仅为 46.1 5%和 86.67% ,而采用 3 g/m3熏蒸 3天 ,各虫态校正死亡率都达 1 0 0 %。 Using different temperatures and different doses of aluminum phosphide, under different processing time on the high temperature pest control and phosphide aluminum fumigation test results show that: Second. The mortality of larvae and adults at 60 ℃ for 60 min was 100% and that of pupae and eggs was 75 min at 55 ℃. The eggs, larvae and adults all died after 15 min at 60 ℃, while the pupae needed 45 min to reach 100% % Of the death rate. Fumigation with aluminum phosphide, larvae and adults sensitive, with 1.5g / m3 for 3 days, all died, but the corrected mortality of egg and pupa was only 46.1 5% and 86.67%, while the use of 3 g / m3 fumigation 3 Day, the correct mortalities of all insect states reached 100%.
