The results are as follows:(1) The relative spectrum sensitivity of the two kinds of compound eyes were similar, both were most sensitive to wavelength of 562nm, and also sensitive to wavelength of 400nm、483nm;(2) The absolute sensitivity curves to these three kinds of sensitive light of the two kinds of compound eyes were similar, all increase with the increment of luminance strength, but the compound eyes of corn borer had stronger response to wavelength of 562nm and 483nm;(3) The two kinds of compound eyes showed similar absolute sensitivity curves to white light, however, showed different sensitivity to light at different time or under different adaptative state.

结果如下：（1）二者具有相似的光谱反应曲线，均对562nm的光最敏感，另外对400nm、483nm光也较敏感；（2）二者对这三种敏感光的光强度曲线近似，在一定范围内均近似线性递增，但玉米螟复眼ERG在562nm和483nm下具有更高的反应幅度；（3）二者对白光的光强度曲线也近似，但随复眼适应状态及测试时间的不同，表现出不同的光敏感性。

Coccinella septempunctata adult life span is longer, an average of 77 days, to adults and larvae prey aphids, spider mites, whitefly, corn borer, Helicoverpa armigera larvae and eggs and so on.

Results show that the insect community structure in the Bt fields differed sharply from that in the CV fields. The populations of the Lepidopterous pests, such as cotton bollworm, corn borer, diamond bollworm and cotton leaf caterpillar, decreased significantly in the BT fields, while the populations of non-target pests with piercing-sucking mouthparts, such as leaf bugs, cotton spider mites, cotton aphids and whiteflies, increased obviously. Much more predators, such as spiders and ladybirds, and much less parasitiods of Helicoverpa armigera were observed in the BT fields.

结果表明，与常规棉田相比，Bt棉田棉铃虫、玉米螟、金刚钻、棉小造桥虫等鳞翅目害虫种群数量显著降低，而盲蝽象、红蜘蛛、棉蚜、烟粉虱等非靶标刺吸式害虫种群数量显著增加；蜘蛛、瓢虫等捕食性天敌种群数量显著增加，而棉铃虫的寄生性天敌种群数量则显著下降。
