大气污染对植食昆虫的影响及作用机制

综述了植食昆虫对二氧化硫、氮氧化物、酸雨、臭氧和氟化物污染的不同反应 ,其基本规律是 :中低浓度的大气污染促进植食昆虫的生长、发育 ,较高浓度的大气污染抑制植食昆虫的生长 ,不同种类的昆虫反应不同 ,植食昆虫对臭氧污染的反应多变而没有较统一的规律。另外 ,还论述了植食昆虫对大气污染的反应机理 :一是大气污染→植物→昆虫途径 ,二是大气污染→生态系统→昆虫途径

Effect of Atmospheric Pollution on Phytophagous Insects and Its Mechanism

Responses of insects to air pollution have been a hot spot of studies since the 1980s.A review is presented of effects of major air pollutants,such as sulfur dioxide,nitrogen oxides,acid rain,ozone,fluorides on phytophagous insects,with a general conclusion that the pollutants,except ozone,when low or moderate in concentration,contribute to growth of the insects whereas when high in concentration,inhibit their growth,but their response to air pollution varies from species to species.To ozone pollution the insects respond variably without following a uniform law.In addition,mechanisms of the effects are also discussed.One is via the host of plants and the other via the ecosystem.
