蝇

One is the South American phorid fly. It lays its eggs on fire ants.

一种南美蚤蝇，它将它的蛋生在火蚁上。

One is the South American phorid fly, it lays its eggs on fire ants, when the eggs break open, the young flies eat the brains of the ants. But researchers don't know how well the flies would do in North American.

他们在火蚁身上产卵，当卵破壳的时候，幼蝇就会吃掉蚂蚁的脑子，但是科学家不知道这种苍蝇对于北美的影响。

Other natural ways to fright the fire ants are also possible.One is the South American phorid fly.It lays its eggs on fire ants.When the eggs break open, the young flies eat the brains of the ants.

其他用于抵抗火蚁的自然界方法同样也是可能的，其中之一是用南美的PHORID苍蝇，PHORID苍蝇将卵产在火蚁身上，当卵孵出的时候，幼蝇将火蚁的脑髓吃掉。

This paper was aimed to study the photodynamic effects of tetrapyrrole compounds on insects and rheumatoid arthritis models.

LetS conside some of the insects found in the house,appaently attempting to escape into the snowy landscape--vitually any winte window,late in the season.shouldpovide good collecting if you quay includes ladybidbeetles,polistes wasps,cluste flies,o elm.1eaf beetles.

让我们看一下在房子里发现的一些昆虫，它仃J显然想遁入雪地中--事实上，晚冬时倘若你留心，可以在任何一扇冬天的窗户上发现云集着好一些昆虫，有瓢虫、长足胡蜂、粉蝇或榆黄守瓜，它们将成为很好的标本。

Mitochondrial 16S rRNA gene and COⅠ gene fragments were amplified and sequenced from 4 wild populations of Portunus trituberculatus. Respectively, 524bp and 658bp long partial gene fragments of the 16S rRNA gene and the COⅠ gene were obtained. A high percentage of A+T base composition in the two sequences was observed, which was similar to the results of studies on drosophila, shrimp, crab and other invertebrates.

对分别采自辽东湾、莱州湾、海州湾和舟山的三疣梭子蟹4个野生群体的线粒体16S rRNA和COⅠ基因片段进行了扩增和测序，分别得到长度为524bp和658bp的片段。2段序列的碱基组成均显示较高的A+T比例（16S rRNA基因70.8%，COⅠ基因63%），这与果蝇、虾类、蟹类等无脊椎动物的16S rRNA和COⅠ基因片段研究结果相似。
