摘要
在新型房式仓内的小型粮垛中进行了ＰＨ３、ＣＯ２混合效熏蒸抗性害虫的试验。试虫有采自河南安阳的赤拟谷盗，对ＰＨ３的抗性系数Ｒｆ＝１８０；采自吉林四平的赤拟谷盗，为ＰＨ３敏感品系；采自河南商丘的谷蠹，对ＰＨ３的抗性系数Ｒｆ＝１９０；采自广东潮州的谷蠹，为ＰＨ３的敏感品系；采自河南许昌的玉米象，为ＰＨ３敏感品系。结果表明在ＡｌＰ（片剂）１．２ｇ／ｍ＾３、Ｃｏ２８％、温度２７℃、ＲＨ７５％的情况下。
The fumigation to control phosphine - resistant insects by using mixture of PH_3 and CO2 was carried out in the small stacks of bagged wheat in the wharehouse. The tested insects were susceptihle and resistant strains (Rf = 180 ) of Tribolium castaneum, susceptible and resistant strains (Rf = 190) of Rhyzopertha ddominica and susceptible strain of Sitophilus zeamais. The results showed that under 27℃ and RH 75%, 1. 2g/m3 of AlP (tablet) with CO2 8% could kill the high resistant strains of T. castaneu,n and R. dominica aftcr sealing for 10 days.
