| 摘 要： | 本试验于1987年在中国农科院兴城果树所综防示范点——辽宁省金州三十里堡苹果园进行。此文应用主分量分析方法研究苹果树不同生长阶段害虫-天敌群落中优势种的组成和季节性变化。结果表明,综防区的防治策略有利于保护天敌优势种。常规防治区凭经验用药,忽视了优势种间的食物网联系,导致杀伤天敌,害虫抗药性增加,而再度猖獗。

| Abstract: | In 1987,systematic investigations on apple insect pests and naturalenemies were conducted in an IPM demonstration area in suburb of Jin-zhou,Liaoning Province.Based on principal component analyses,the composition and seasonal succession of dominant species in insectpest-natural enemy community were explored.The results showed thatthe IPM strategies was in favor of the protection and utilization of na-tural enemies,while in routine control area,the food web among thosedominant species were ignored by empirical pesticide treatments,causing the significant population decrease of natural enemies,increaseof pesticide resistance and resurgence of apple insect pests. |
