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

Methods The necrophagous fly L. sericata were reared at constant temperature of 20 ℃, 24 ℃ and 28 ℃ respectively and were tempted to lay eggs with lean pork. One Sample was taken at 12 h intervals till 50% of the larvae were in pupae stage. Then, the anterior spiracle, posterior spiracle and cephalopharyngeal skeleton were investigated through digital image processing combined with morphologic observation.

在20 ℃、24 ℃和28 ℃下饲养丝光绿蝇，瘦猪肉诱其产卵，每隔12 h取样1次，直至50%以上幼虫化蛹为止，采用形态观察与图像分析相结合的方法对幼虫前气门、后气门、头咽骨进行观察研究。

Moth whose larvae form nests by rolling and tying leaves with spun silk .

幼虫用卷起的树叶和丝来筑巢的蛾子。

After hatching, squid hatchlings were separated to incubate in two different photoperiod regimes, 12 hr: 12 hr and 24 hr constant light conditions. Squid larvae were maintained as long as possible. Although the trend which older squids have more increments on the statolith than younger squids is consistent, the slope between the increments and survival days is less than one. The time required to form one ring on the statolith is needed for more than one day.

孵出后的个体分别饲养在两种不同的光照周期下，分别为十二小时亮十二小时暗及二十四小时亮两种光周期，在两种光周期下培养的个体都在平衡石上发现新生成的纹路，纹路生成的数量虽然随著培养时间的延长而增加，轮的生成与光照周期间没有相关性，一条新的纹路生成所需要的时间却大於一天，一般需要两至三天才生成一轮。

To screen resistant rice varieties in Liaohe Valley to the rice stem borer Chilo suppressalis Walker, development of and damage by the borer larvae on the varieties were examined using intact-plant resistance evaluation method, and morphological and biochemical characteristics and number of silica cells of the rice varieties were determined to explore the potential resistance mechanisms.

采用活体成株鉴定法测定了辽河流域主栽水稻品种对二化螟发育和为害的影响，同时测定了不同品种的主要形态特性、硅细胞数量和主要生化特性，评价这些品种对二化螟的抗性、分析其发生的可能机制。

The age structure of striped stem borer, Chilo suppressalis, overwintering in different type of rice fields and wild rice fields was investigated, and post winter feeding and pupation dynamics were compared among larvae in different instars.

调查了不同类型稻田及茭白田中二化螟的越冬年龄结构，比较了不同龄期幼虫之间在冬后取食与化蛹动态方面的差异。结果表明，越冬虫龄以双季晚稻田中明显较低，中稻田与茭白田中相对较高。

The content variation to Chrysopa septempunctata"s vitellin was detected through ELISA. It indicated that vitellin was utilized gradually during embryonic development, and a fallowing trend in form of straightline was found in the whole embryonic development. Vitellin couldn"t be detected in just hatched larvae.

通过ELISA来测定大草蛉的胚胎发育和胚后发育中卵黄蛋白的含量变化，随着胚胎的发育，卵黄蛋白逐渐被利用，在整个胚胎发育过程中呈直线下降趋势，在刚孵化的幼虫中已检测不到卵黄蛋白的存在。
