This dissertation studied the overcompensatory responses of cotton,Gossipium hirsutum L. plants to leaf loss, square loss and cell sap lossand the changes in some physiological and biochemical contents with timein the case of overcompensation. The artificial defoliation, early squareremoval and aphis colonization were used as three types of simulated ornatural herbivory. The target of this study is to elucidate thephysiological mechanism of cotton plant overcompensation for insectherbivory.

本文以棉花为实验材料，采用人工去除棉花一部分叶片、花蕾及接种棉蚜的方法，分别模拟昆虫食叶、食蕾及吸汁为害等三种为害方式，研究棉花对于失叶、失蕾及损失细胞汁液所产生的超补偿作用，及一些生理生化代谢随棉花发育时间进程变化的情形，以期较为系统地从多个方面阐明棉花对于虫害超补偿作用的生理学机制。

By use of High Speed TLC Scanner,CS-920,was used to apply droplet of insecticide solution to the dorsum of the testinsect.

The life table analysis in the laboratory showed that there were no significant differences in survival rate, nympha duration, and fecundity between laboratory populations of aphids fed on Bt and non-Bt cotton.

对Bt棉在长江中游棉区对各种主要靶标及非靶标害虫影响的系统评价表明，在长江中游棉区种植Bt棉，将有助于控制该地区的棉铃虫和红铃虫的危害，减少棉田农药的使用次数，控制棉蚜的暴发，使棉田生态系统朝良性的方向发展。

The migratory and sedentary lines were screened and monitored, the heredity power of take-off angel traits was 0.99-0.81 from the first to second generations. The migratory and sedentary lines could hybrid successfully , and the migration potential energy could be inherited maternally or paternally to offspring.

首次发现春季木槿上棉蚜种群存在迁飞特性上的分化，并且筛选出了迁飞型和居留型，两型的杂交后代在起飞角度和有翅蚜产生比率上表现出了明显的亲本遗传效应。

Mulberry leaves: adding water to 5 times, boiled liquid, liquid plus 0.5 kg per 2 kg of water, or water extract of mulberry leaves sprayed 10 times to control cotton aphid and spider mite.

桑叶：将其加水5倍，煮成原液，每0.5公斤原液加水2公斤，或桑叶10倍水浸液喷洒，可防治棉蚜和红蜘蛛。

In Xinxiang Aera of Henan Province in 1997, the occurrence of cotton pests were investigated in the Bt cotton and common cotton fields The result showed that the numbers of cotton bollworm egg were similarly in both fields, but that of survival larvae on Bt cotton were lower than that on common cotton The occurrence of cotton aphis was no difference but the spider mite were more heavy in Bt cotton field At the same time,control strategy against cotton pests were discussed for the Bt cotton

对河南新乡棉区种植的转Bt基因棉和常规棉棉田虫情进行了定点系统调查和大田普查，结果表明：棉铃虫在两种棉田棉花上的落卵量无明显差别，而幼虫存量差异显著，Bt棉棉花上幼虫存量显著降低；Bt棉对棉蚜的发生无明显的影响，而Bt棉上棉红蜘蛛的发生比常规棉略重，同时初步研究制定出种植Bt棉后的棉虫综防对策
