磷化氢气体具有挥发性、渗透性、扩散性,杀虫效果好等特点,60年代初期,我国开始广泛应用磷化氢防治储粮害虫。长期单一的使用磷化铝药剂反复熏蒸杀虫,使虫体产生了较大的抗药性,直接影响防治效果,威胁粮食的安全储藏。为此,我们选择四种常见的仓储害虫作抗药性的研究和磷化铝与防虫磷混合使用的试验。 Phosphine gas has the characteristics of volatility, permeability, diffusibility and insecticidal effect. In the early 1960s, China began to widely use phosphine to prevent and control stored grain pests. Long-term single use of phosphine pharmaceutical fumigation repeatedly fumigation insects, the parasites have a greater resistance, a direct impact on prevention and control of the effect of threatening the safe storage of food. To this end, we chose four common storage pests for resistance studies and mixed use of aluminum phosphide and pest control.
