虱的

This thesis focuses on beetle Cybister tripunctatus in addition to some other species of beetles and studied the elytron's micro-structure. We found that there are many concaves、hollows and holes on its structure; the configuration of this material is compound samdwich; the linkage-structure between elytra adopts the concave-protuberant mesh joint with some bristle.

本文以东方龙虱为重点研究对象，并综合了四个科的十个物种，通过对甲虫鞘翅微结构的观测，发现东方龙虱鞘翅表面遍布着很小的凹坑；从其鞘翅断面来看，内部存在着许多空腔和孔道结构，而且甲虫鞘翅是复合层状结构；对鞘翅间联接处研究发现，联接机构采用了凹凸啮合结构，在局部区域存在微小毛刺和突起结构来增加摩擦接触。

The 6 AChE Genes from L.bostrychophila,L.entomophila and L.decolor were demarcated into Insect TypeⅠAChE Gene and Insect TypeⅡAChE Gene.4 Gene cloning of nAChR and mRNA expression level in L.bostrychophilaTwo nicotinic acetylcholine receptor subunit genes,Lb al and Lb a8,were cloned from the psocid L.bostrychophila.The full length cDNAs of Lb a1(GenBank Accession No.: EU871527) and Lb a8GenBank Accession No.

昆虫的两类AChE严格的区分，其中Ⅰ型AChE先与脊椎动物AChE聚合后才与Ⅱ型AChE相聚，说明两类AChE基因在物种分化前就已经分化。4嗜卷书虱烟碱型乙酰胆碱受体基因克隆及其mRNA表达水平研究利用RT-PCR和RACE技术成功克隆获得了嗜卷书虱2个烟碱型乙酰胆碱受体亚基的全长序列，分别命名为Lb a1(GenBank登录号：EU871527)和Lb a8(GenBank登录号：EU871526)。

Tabaci was the shortest (19.3 d) on hairy gourd and the longest (29.0 d) on bitter cucumber, the survival rate from egg to adult was the highest (92.85%) on cucumber and the lowest (53.08%) on bitter cucumber, the laid eggs were the most (187.4 eggs per female) on cucumber and the least (30.0 eggs per female) on bitter cucumber, and the longevity was the longest (25.2 d) on cucumber and the shortest (10.9 d) on bitter cucumber. The intrinsic rate of increase r(subscript mon cucumber, hairy gourd, bitter cucumber, and sponge gourd was 0.1453, 0.1429, 0.0616, and 0.1055, respectively.

结果表明，B型烟粉虱在节瓜上的世代发育历期最短，为19.3d，在苦瓜上的世代发育历期最长，为29.0d；世代存活率在黄瓜上最高，为92.85%，在苦瓜上最低，为53.08%；平均单雌产卵量在黄瓜上最多，为187.4粒，苦瓜上最少，为30.0粒；雌成虫寿命以在黄瓜上最长，为25.2d，在苦瓜上最短，为10.9d.B型烟粉虱在黄瓜、节瓜、苦瓜和丝瓜上的内禀增长率r(下标 m分别为0.1453、0.1429、0.0616和0.1055。

Better prevention and control of pesticides will be marked with objects, such as imidacloprid, Actara, Le Meridien, for sucking mouthparts of the aphid, whitefly, leafhopper, canarium; 15% more than for the control of anti-ADM Alternaria mali disease, pear black spot disease; Celest Fusarium, Rhizoctonia diseases caused by a high control effect; Diflubenzuron Insect Growth Regulators such as applied to control pests and moths Phyllocnistis Mosquitoes pest, Avermectin streptozotocin on the type of anti-mite efficient.

好农药都会标明防治对象，如吡虫啉、阿克泰、艾美乐，适用于刺吸式口器的蚜虫、粉虱、叶蝉、木虱；15%多抗霉素用于防治苹果斑点落叶病、梨黑斑病；适乐时对镰刀菌、丝核菌引起的病害具有很高的防效；灭幼脲等昆虫生长调节剂适用于防治潜叶蛾类害虫和蚊类害虫，阿维菌素对叶螨类防效高。

The number of the adults and nymphae of psocids at the surface of the stored wheat was as many as that at the inner of stored wheat when the temperature was 15℃, the number of the psocids at the surface of the stored wheat would exceed the psocids number at the inner when the temperature exceed 20℃.

结果表明，嗜虫书虱在小麦堆的种群变化因粮温的上升而增大，并表现为15℃左右时粮堆表层和粮面下100cm处数量相近，粮温升达到22℃以上后，粮堆表层的书虱数量明显多于粮堆内部。

Therefore, its morphological identification, test of the squash silverleaf induced as well as two genetic markers (RAPD-PCR and rDNA-ITS1) were carried out in order to establish a base for effective control.

此外还对北京地区B型烟粉虱田间的发生情况做了初步调查。搞清我国烟粉虱生物型的种类及其分布是采取有效防治措施之前迫切需要解决的问题。

To compare the susceptibility of two homogenous genotypes of transgenic indica rice, namely, B1 and B6 expressing a gene of cry1Ab from Bacillus thuringiensis Berliner against the non-target pest, the white-backed planthopper, Sogatella furcifera, with that of their non-transgenic parental cultivar (Jiazao 935), the development duration, oviposition behavior and fecundity of this planthopper on B1 and B6 were measured as compared with those on Jiazao 935 using the methods including a developmental duration measurement, an electronic monitor of the oviposition behavior.

为了比较2个转cry1Ab基因抗虫籼稻品系B1和B6对其非靶标害虫白背飞虱敏感性与其非转基因亲本对照嘉早935的差异，采用历期测定和产卵行为电子记录等方法分别测定了白背飞虱于B1和B6及嘉早935上的发育历期、产卵行为及繁殖力。

These results indicated that a significant mutualism developed between TYLCCNV and the Q biotype whitefly but not so obvious between TYLCCNV and the ZHJ2 biotype whitefly.

这表明，TYLCCNV与Q型烟粉虱之间能够产生显著的互惠关系，而与ZHJ2型烟粉虱之间的互惠关系则不显著。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
