昆虫免疫反应是昆虫在受到外源刺激时产生的一系列的防卫反应,分为体液免疫和细胞免疫两种,二者共同作用抵御细菌、线虫、病毒、寄生蜂卵等外源病原物的侵染.亚致死剂量杀虫剂可显著影响昆虫对病原菌免疫反应能力.笔者主要根据文献,综述亚致死剂量杀虫剂对昆虫免疫反应方面的影响,旨在进一步了解杀虫剂的亚致死效应,了解亚致死剂量杀虫剂与病原微生物对害虫的联合作用,为害虫综合防治中化学防治与生物农药的协调应用提供参考.%Insect immunity is a defense response against attack of exogenouspathogens or other adverse stimulation.The insect immune system is comprised of humoral immunity and cellular immunity.Both of the immunities act co-operatively in response to attack of exogenous pathogens such as bacteria,nematodes,virus,parasitic wasp eggs,etc.These immunity responses can be e influenced obviously by sublethal exposure to insecticides.The effect of sub-lethal dosage of insecticides on insect immune response was reviewed to have a good understanding of sublethal effect of insecticides,and the synergistic effects of combined application of sublethal dose of insecticides and mycopathogenes on pest insects.This review may provide a reference for combined application of chemical insecticides and bio-insecticides in integrated pest management.
