在库蚊属4个亚属中，路蚊亚属与库蚊亚属有更近的亲缘关系，这也印证了库蚊亚属某些幼虫与路蚊亚属幼虫具有相似习性的遗传基础。

When water temperature was 26.4±0.45℃, salinity 25.50 and pH 8.0~8.2, C. antiquata veliger with an average shell length of 196 μm, after 72 hours of cultivation, reached attachment metamorphosis at a rate of

在水温26.4±0.45℃，盐度25.50，pH 8.0~8.2的条件下，平均壳长196 μm的西施舌壳顶面盘幼虫经72 h培育，幼虫附着变态率为

The contents of vitamin A and vitamin B in the bee larva is very rich and more than those in cod liver oil, vitellus and milk.

蜜蜂幼虫中维生素A和维生素D的含量十分丰富，超过鱼肝油、蛋黄和牛奶的含量，蜜蜂幼虫还含有酶、激素等多种生物活性物质。

Environmental manipulations were used to explore the effects of larval competition on the life history strategy of the bean weevil, C.

本研究首次提出幼虫期环境经历会影响成虫期生活史策略反应的假说，并探讨四纹豆象幼虫竞争经历对成虫生活史特徵的影响，以对此假说加以检测。

Results The peak of antibacterial activity appeared at 36-48 hafter induced by four inducements (Because many M.domestica larvae pupated,we did not observe the peak of antibacterial activity by heat-shock). The antibacterial activity of antibacterial proteins by S.aureus was best,and the antibacterial activity of antibacterial proteins by heat-shock was better than control group.

结果 各诱导组诱导家蝇幼虫产生抗菌蛋白达最大活性时间为诱导后36～48h(热诱导后家蝇幼虫很快化蛹，未观察抗菌蛋白产生高峰时间)；金黄色葡萄球菌诱导后的抗菌蛋白抗菌活性最佳，热诱导后的抗菌蛋白抗菌活性也较未诱导组好。

Pupation rate, immatured worm, dead cocoon rate, cocoon shell weight, cocoon weight, percentage of cocoon shell weight, cocoon crop from 10000worms and cocoon shell weight from 10000 worms were controlled by genes with additive and dominant effects, but no epistatic effects in these traits.

结果表明，家蚕的虫蛹率、幼虫生命率、死笼率、全茧量、茧层量、茧层率、万蚕收茧量、万蚕茧层量8个性状同时受基因的加性效应和显性效应控制，不存在上位作用，茧层量、茧层率、万蚕收茧量呈现部分显性，虫蛹率、幼虫生命率、死笼率、全茧量、万蚕茧层量5个性状则呈现超显性。

Manypharmacological experiments have been conducted to determine the effects of adrenergic agonistand antagonist of catecholamine receptors on Meretrix meretrix metamorphosis.

药理学实验分别采用了几种儿茶酚胺类受体的激动剂和抑制剂来处理幼虫，检验它们在幼虫变态过程中的作用。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
