Its website provides the information of related societies, search engine, the links to another insect pages(includes the fastest flyer, the longest diapause, the most tolerant of cold, the most tolerant of dessication, the smallest eggs and so on), and links to meaningful sites(such as: why do Insects Aggregate, an introduction to insect territoriality and so on), and key to the orders of insects.

Insect resistance to Bt toxin is related with the variation of cadherin-like protein gene.cDNA fragment of cadherin-like protein gene in the fifth instar larva of oriental tobacco budworm was amplified using degeneracy primers and RT-PCR technique,and the target fragment was further sequenced after being cloned into pMD18-T vector plasmid.

本研究以烟夜蛾五龄幼虫中肠的总RNA为模板，根据已经克隆的其他昆虫的类钙粘蛋白基因序列设计引物，利用RT-PCR技术扩增出了烟夜蛾类钙粘蛋白基因的cDNA片段，将其连接到pMD18-T载体，转化大肠杆菌后筛选阳性克隆并进行序列测定，测序得到的1 335 bp的片断编码444个氨基酸残基。

The vip3A genes amplified from wild-type Bt strains S184 and 611 with different levels of activity against lepidopteran insect larvae were cloned into pGEM-T Easy vector. Alignment of these 2 putative Vip3A proteins with 8 others showed that vip3A genes are highly conservative.

从以上菌株中挑选2个对夜蛾科害虫具有较高和较低毒力的菌株，即S184和611，分别进行vip3A基因的克隆和测序，再已报道的其它8个vip3A基因进行核苷酸和氨基酸序列比较，结果表明，vip3A是一个极其保守的基因。
