草蛉

Chrysopa septempunctata Wesmael is a kind of important natural enemy insects, which can control agricultural and forestry pests effectively, such as aphids, coccids and aleyrodid. Due to wide feeding habits, large appetite, wide distribution and large quantity, it has been paid great attention to by biological control workers.

大草蛉Chrysopa septempunctata Wesmael是一类重要的天敌昆虫，能够有效地控制蚜虫、蚧虫、粉虱等农林害虫，由于它的食性广、食量大、分布广、数量多而深受国内外生防工作者的重视。

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。

Chrysopa glue secreted by the body of the eggs quickly stick it in a safe height, he used glue in a few seconds to harden the egg barely hanging in the air.

草蛉用身体分泌的胶水将它的卵快速粘在一个安全的高度，他用的胶水在几秒钟之内就变硬，卵几乎还悬挂在空中。

The responses of Chrysopa pallens Ramber to light stimuli with different intensities were investigated by means of electroretinogram technique and behaviour measurement.

运用视网膜电位(electroretinogram， ERG)技术和行为学方法研究了大草蛉Chrysopa pallens Ramber成虫的光强度反应。

According to amino acid sequence to vitellin which has the structural character of GL/ICG motif near C end, two degenerate primers were designed and Chrysopa septempunctata s RNA was extracted, and a 900bp fragment was amplified by RT-PCR.

根据昆虫卵黄蛋白氨基酸序列在靠近C端存在GL／ICG区域的结构特点，设计了两条简并引物，提取大草蛉的RNA，用Takara的3′—RACE试剂盒进行RT-PCR，扩增出一段900bp的片断。

The variation to vitellin polypeptide was studied by SDS-PAGE during embryogenic and postembryonic development to Chrysopa septempunctata. The results indicated that vitellin was degradated constantly during embryonic development, and the bands of vitellin couldn't be detected in the 4th day of ovum development.

用SDS-PAGE研究了大草蛉胚胎发育和胚后发育过程中卵黄蛋白多肽的变化动态，结果表明，卵黄蛋白在胚胎发育过程中被不断降解，在卵发育的第4天已经基本上看不到卵黄蛋白的条带。

Temperature is an important environmental factor which influences insects reproduction. In order to obtain the highest reproductive efficiency, Chrysopa septempunctata was fed with aphids at 15 #,25 # and 30 # respectively.The results indicated that oviposition period was prolonged obviously and oviposition quantity to a single female worm was the highest at low temperature of15#.

温度是影响昆虫生殖的重要环境因子，为了获得最高的繁殖效率，比较了在15℃、25℃和30℃的条件下用蚜虫做食料来饲养大草蛉，发现在低温15℃的条件下，单雌产卵量最高，产卵历期也较长。

In consideration of the natural suppression of Chrysopa septempunctata Wesmael to the thrips populations,the ET might relax to 624 insect-days,i.e.the fourth level of injury with the injured area about 1/2 to 3/4 of the whole leaf and its edges curled upward.

考虑大草蛉对桑蓟马的捕食作用，则桑蓟马防治指标可定为4级受害水平，即叶片受害面积占全叶的1/2～3/4，叶缘向上卷起。

Chrysopa sinica and Orius sauteri showed closely sympatricand synchronous with the two leaf mites,but wide niche breadthesof food recipes weaken their functions of predatorness when themites and A.citricela appear at the same time.

六、草蛉、小花蝽与两叶螨的时间同步性和空间同域性较强，但因其食谱生态位较宽，当叶螨与蚜虫并存时，便降低了它们对叶螨的捕食效能。

The designer selected the four insects: Coccinella Septempunctata,Sympetrum Croceoium,Chrysopa Septempunctata and Tenodera Aridifolia Sinensis as the motifs, which form big oblique lines in different directions and configurations.
