摘　　要：本文报道了低浓度辛硫磷对两种贮粮有害昆虫的耐受性诱导实验。结果表明,昆虫黄粉虫(TenebriomolitorL.)和赤拟谷盗(TriboliumcastanenmHerbst)的农药耐受性可以不依赖于生态选择而形成,而且涉及多基因的个体水平的生理适应过程。生态选择作用于种群演化,导致寡基因决定的高水平抗性;而生理适应作用于个体,是机体内代谢过程的多水平调节。然而低浓度农药引起的这种耐受性与添加雷公藤(TripterygiumwilfordiiHook.f.)粉所导致食物成分改变的关系不明显。Studying on the low-dose effects of phoxin on two granary populations, Tribolium castanenm Herbst and Tenebrio molitor Linnaeus, it is concluded that the insect tolerance to an insecticide can result from the physiological (adaptation;) it is determined by many factors what many genes and environmental factors such as foods are involved in. The physiological adaptation process is different from the ecological adaptation, which induces high-level insecticide resistance,for it is a population evolution driven by the natural selection. The tolerance to insecticide was induced by low dose (phoxin) administration as a physiological adaptation process,which is implicated in multi-level regulations in an organism,and however, was not affected by insects′ nutritional change by adding the Chinese herb,Tripterygium wilfordii Hook.f.,in their foods.
