转基因自控田中，害虫、天敌及中性昆虫亚群落的个体数分别占总个体数的87 . 6 % 、 10 . 3 % 、 2 . 1 % ，两块转基因棉田昆虫群落的构成比例相似，害虫及天敌亚群落的优势种相同。 - Transgenic bt cotton mainly affect high - instar larvae by retarding the growth and intering the proceeding of ecdysis , pupation , and eclosion . the growth retardation leads to the postponement of growth period duration ( the showed that growth period duration prolonged 17 days ) . feeding the larvae with the tissue of the transgenic bt cotton and the moths with the flower of transgenic bt cotton , the number of eggs and hatching rate decreased obverviously
转基因药防田中，天敌昆亚群落的个体数占整个昆虫群落总个体数的10 . 0 % ，其优势种为蜘蛛类、七星瓢虫( coceinellas叩te即uneitatalinnaeus ) 、龟纹瓢虫( prol ， laea少只ponjcagoeze ) 、大眼蝉长蜷( prqp . ylaeajaponicagoeze )和草岭(助rys叩asepre即unetatawesmael ) 。
