摘要
针对小麦仓中下层局部生虫 ,采用粮堆局部处理机环流熏蒸 ,分两次投药 ,共计熏蒸处理时间为两周。实验证明 :在处理部位PH3浓度 1 0 0～ 30 0 ppm可以保持 1 2天左右 ,粮堆中的害虫全部杀死 ;经检查埋入粮堆的赤拟谷盗、谷蠹和玉米象 ,成虫死亡率 1 0 0 % ,对虫粮培养 4 2天后 ,检查F1代为零。
To control the insects in middle and lower layer in bulk stored wheat,partial recirculation fumigation was carried out in two weeks.The results showed that the PH 3 concentration can maintain 100～300ppm for about 12 days.The insects inside bulk were all killed,and after 42 days incubation no insects was found.
