| 摘 要： | 在500 Pa正压半衰期为30 s的拱板仓中对储藏小麦中抗性488倍的嗜卷书虱LiposcelishbostrychophilusBadonnel进行磷化氢熏蒸,包括预置试虫虫笼、潮解施药、气体环流、检测浓度、补充药剂、检查效果、熏蒸后防护等。主要结果为：初次施入磷化铝片剂44 kg后,仓内磷化氢浓度下降很快,以后分别于第14 d、第19 d和第37 d先后补充施药6 kg、12 kg、12 kg,仓内磷化氢浓度保持在200 mL/m3以上的时间维持45d。在大部分时间保持磷化氢浓度200 mL/m3~500 mL/m3的情况下,虫笼中的害虫到第45 d才全部死亡,试验仓在后期隔离防护的情况下180 d没有检测到书虱。结果说明,密闭较差的仓房熏蒸中补充施药才可能有效保持磷化氢浓度,在200 mL/m3~500 mL/m3的浓度下熏蒸需要很长的时间才能完全杀死抗性嗜卷书虱。

| Abstract: | A phosphine fumigation trial against Liposcelish bostrychophilus Badonnel with 488 times of phosphine resistance was carried out in an arch storage of 30 seconds half time at 500 Pa pressure.The test included test cage monitoring,applying aluminium tablet on trays,gas recirculation,phosphine concentration monitoring,fumigant supplement etc..Phosphine concentration decreased quickly after applying 44 kg of the aluminium phosphide tablet,but for maintaining the concentration above 200 ppm for 45 days,6 kg,12 ... |
