摘要
针对目前用于防治储粮害虫的空仓杀虫剂杀虫效果差,施用操作麻烦,杀虫剂对操作人员身体危害大等问题,在空仓环境内,进行了残杀威、敌百虫、溴氰菊酯及高效氯氰菊酯4种烟剂对谷蠹、米象、赤拟谷盗、锈赤扁谷盗、锯谷盗和嗜卷书虱等6种储粮害虫成虫的防治效果测试。结果表明,2.5%溴氰菊酯烟剂杀虫效果最好,100%杀死试虫;2%高效氯氰菊酯烟剂杀虫效果次之,试虫死亡率在99.3%以上;20%残杀威的触杀效果较溴氰菊酯、高效氯氰菊酯差一些,赤拟谷盗试虫死亡率85%以上;30%敌百虫烟剂的触杀作用较差,谷蠹和锈赤扁谷盗试虫的死亡率在85%以上。
Since the insecticides that used in empty silo have many problems, such as poor insecticidal effect, application of operational problems, and harm to operators, four fume of insecticides, Propoxur, Trichlorfon, Deltamethrin and Beta cypermethrin were applied on six major species of stored grain pests which were Rhizopertha dominica （Fabricius）, Sitophilus oryzae （ Linn6）, Tribolium castaneum （Herbest）, Cryptolestes ferrugineus （Stephens）, Oryza- ephilus surinamensis （ Linn6 ）, and liposcelis bostrychophia （ Badonnel ）. The results showed that the best fume was 2.5% deltamethrin,and kill all of six major species of stored grain pests adult. The fume of 2% beta cypermethrin was take second place ,the mortality rate of adult up to 99.3%. The fume of 20% propoxur control effect was lower than fume of 2.5% deltamethrin and 2% beta cypermethrin, and the mortality rate of Red flour bettles adults up to 85%. The poor fume was 30% trichlorfon,the mortality rate of Lesser grain borer and rusty grain beetle above 85%.
