Like spiders, adult mites have eight legs, but their freshly hatched "larvae" have only six—they acquire an extra pair of legs after moulting.

和蜘蛛一样，成年螨虫有八条腿，但新孵化出的"幼虫"只有六条腿——它们蜕皮后会长出另外一双腿。

In present study, RAPD markers are used to analysis the population genetic structure of rotifer Brachionus calyciflorus in Donghu Lake.

利用18种寡核苷酸引物对轮虫种群遗传结构进行RAPD分析，18种引物总共得到了187条条带，其中多态条带135条。

A bird zeroing in on a flag-footed bug perched on a passionflower might see the flutter of red "flags"—the insect's attempt to divert the hunter's bite to nonessential limbs, away from its vital core.

一只旗足虫栖息在一株西番莲上，在空中逡巡觅食的鸟类有可能会被它那飘动的&红旗&分散注意力，就达到了旗足虫舍一两条细足来保住重要器官的目的。

Total RNA was isolated from the forth instar larvae of the armyworm,Mythimna separata Walker.An α and a β tubulin cDNA sequences were cloned by RT-PCR and rapid amplification of cDNA ends.

以黏虫4龄幼虫为材料提取总RNA，利用RT-PCR和cDNA末端快速扩增技术，分别扩增得到该虫的α和β微管蛋白基因的cDNA序列各1条。

Armigera BBMV, on the contrary few membrane proteins can be got by dissoluted in M. separata BBMV, and the concentration of membrane protein in M. separata BBMV is lower than in H.

棉铃虫中肠BBMV解离后得到许多可溶性膜蛋白，相比较粘虫中肠BBMV解离后得到的可溶性膜蛋白条带较少，并且粘虫中肠BBMV可溶性膜蛋白的含量明显低于棉铃虫。

Using the total RNA of merozoites of Eimeria acervulina isolated from Guangdong Pro- vince as template,a partial segment of 3-1E gene was amplified by RT-PCR. The gene fragment 682 bp inlength was cloned into pGEM-T Easy vector,and the recombinant plasmid was identified by PCR,restric-tion enzyme analysis and sequencing. The homology analysis revealed that the nucleotide homology be-tween the 3-1E gene of the E.

根据GenBank中登录的堆型艾美球虫3-1E基因序列，设计了3条引物，以广东株堆型艾美球虫裂殖子总RNA为模板，利用反转录-聚合酶链反应扩增获得了3-1E基因部分片段，将这一片段克隆至pGEM-T Easy载体中，经PCR、限制性内切酶分析和克隆片段的序列测定、比较，证实了克隆片段的可靠性。

The results showed that the most suitable time to isolating the Larva from the experiment animals, which were experimentally infected with canine Trichinella was on the fiftith day; the most suitable time of degesting was at 37℃ for 17 hours; 38℃ for 14 hours; 39℃for 19 hours; 40℃ for 10 hours; the most suitable inquantity to inoculate per millilitre was 6000 strips; the best temperature was at 37℃; the best gas condition was in the CO2gas incubator and the concentration of CO2 was 8 per cent; the most suitable pH was at 7.0; the most suitable medium was RPMI-1640; the best nourishment component was peptone; the most appropriate time interval of changing medium was about 24 hours; the best time to observe was at 24 hours.
