| 摘 要： | 2008—2011年在新疆莎车县调查研究了杏树对棉田主要害虫及自然天敌种群发生的影响。研究表明杏棉间作田主要害虫及天敌种类与棉单作田一致。杏树间作种植模式对棉田牧草盲蝽Lygus pratensis、棉蓟马Thripstabaci和棉长管蚜Acyrthosiphon gossyfii的种群发生有一定影响,不利于其在田间发生;对棉蚜Aphis gossyfii、棉叶螨Tetrangchus urticae影响不大。棉田瓢虫和食虫蝽天敌受间作和棉蚜发生量的双重影响。间作有利于蜘蛛数量的增加。

| Abstract: | A survey was conducted to assess the effects of apricot trees on insect pests and their natural enemies in adjacent cotton fields in Shache county, Xinjiang Province from 2008 to 2011. The results show that the species composition of natural enemies and insect pests was similar between isolated cotton fields and those adjacent to apricot trees. Apricot trees, did however, have a negative effect on the occurrence of Lygus pratensis, Thrips tabaci and Acyrthosiphon gossyfii. Interplanting and the occurrence of Aphis gossyfii greatly influenced on the occurrence of ladybirds and bugs. Proximity to apricots also appeared to increase spider abundance. |
