摘要
阐述了新疆棉区主要害虫的演替及其机理。 195 0～ 196 0年主要害虫为黄地老虎、牧草盲蝽象、烟蓟马、苜蓿蚜为主 ;1970～ 1980年以棉铃虫、烟蓟马、棉长管蚜、棉红蜘蛛为主 ;从 1990年开始以棉铃虫、棉蚜、棉红蜘蛛为主。导致这一演替的主要原因为作物布局、耕作制度、栽培方法、管理技术的变化和农药化肥的过量施用。
The succession and its mechanism of cotton pests in Xinjiang were summarized in this paper.From 1950s to 1960s,the main pests were yellow cutworm (Agrotis segetum),tarnished plant bug (Lygus pratensis),tobacco thrips (Thrips tabaci),and aphid (Aphis medicaginis);while from 1970s to 1980s,the main pests were cotton bollworm (Heliothis armigera),tobacco thrips (Thrips tabaci),aphid (Acyrthosiphom gossypii),and two-spotted spider mite (Tetranychus urticae);and from 1990s,the main pests were cotton bollworm (Heliothis armigera),cotton aphid (Aphis gossypii),and two-spotted spider mite (Tetranychus urticae).The main reason for this succession might be the changes in crops distribution,cultivation type,planting method,management technique and over-use of chemical pesticides and fertilizers.
