小鳞翅目

Total RNA was isolated from the third instar larval body of the black cutworm, Agrotis ipsilon.The two actin cDNA sequences were cloned by RT-PCR and rapid amplification of cDNA ends and were designated as Aiactin1 and Aiactin2, respectively.

本研究以鳞翅目夜蛾科昆虫小地老虎［Agrotis ipsilon］3龄幼虫整个虫体为材料提取总RNA，利用RT-PCR和cDNA末端快速扩增技术，分别扩增得到2条肌动蛋白的cDNA序列Aiactin1和Aiactin2。

The orders with high species richness were Hymenoptera (168 species), Diptera (90 species), Coleoptera (44 species), Homoptera (26 species), Hemiptera (23 species), Araneida (18 species) and Lepidoptera (12 species).

棉田节肢动物物种较丰富的目为膜翅目(168种)、双翅目(90种)、鞘翅目(44种)、同翅目(26种)、半翅目(23种)、蜘蛛目(18种)和鳞翅目(12种)，棉田物种数最多的科为姬蜂科和姬小蜂科，分别有22和21个物种。

There are a total of 34,782 individuals belonging to 15 orders, 102 families were found in this study. And the dominant groups among them were Myriapoda、Lycosidae、Miridae、Delphacidae、Cicadellidae、Aphidoidea、Margarodidae、Geometridae、Noctuidae、Olethreutidae、Braconidae、Chrysopidae、Coccinellidae.

调查共发现节肢动物个体34782个，分属3纲、15目、102科，其中优势类群主要是多足纲、蛛形纲狼蛛科、半翅目异翅亚目的盲蝽科，同翅目的飞虱科、叶蝉科、蚜科、蚧科，鳞翅目的尺蛾科、夜蛾科、小卷蛾科，膜翅目的小茧蜂科、小蜂总科，脉翅目草蛉科、鞘翅目瓢虫科。

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。

By the time of its fall, most of the prisoners were writers who had written against the corruptions of the government.

到它被攻陷的时候，里面多数的犯人是写了反对政府贪污文章的作家。

The most obvious variation to ovum morphological character was that the color was changed from light green to sepiaceous in embryonic development, and all the ovums were almost hatched after 96h.

在胚胎发育过程中卵的形态特征最明显的变化是颜色从淡绿到深褐色，卵在发育96h后卵基本全部孵化。
