幼虫的

The development speed of gynogenetic embryos was later than that of the control group, and aneuploids were found in this study. The obvious improved survival of trochophore larvae with a peak at 40s UV exposure suggested the presence of a Hertwig effect in the gynogenesis of A. pectinata. When sperms were irradiated for 40s, the cleavage rate was relatively high (51.2%), the developmental rate of D-larvae became zero, and the rate of haploid reached the highest (36.8%).

经紫外线照射的精子受精后所产生的单倍体胚胎发育速度慢于正常受精所产生的二倍体胚胎，各照射组均出现非整倍体。40s照射组中卵裂率达到51.2%，D型幼虫发生率为0，单倍体率最高，达到36.8%，出现"Hertwig效应"。

Was also observed and evaluated ,The poison symptoms of tropically treated M.separata were observed, following a similar pattern of nerve poisoning: excitation, convulsion, paralysis, and death. The effect of acetone extract from Ferula.ferulaeoidis on the development and hatch of the eggs and survival of hatched larvae as well as ovicidal activity was observed and estimated.

蛹的生长发育有抑制作用，中毒粘虫先后表现出兴奋、痉挛、麻痹等症状，最后死亡；对黄粉虫蛹生长发育的抑制作用类似于保幼激素(Juvenile hormone analogs， JHA)活性；对棉铃虫(Heliothis armigera Hübner)卵发育、孵化及初孵幼虫存活有明显影响，表现出一定的杀卵活性。

Impacts of transgenic Bt rice on survival and growth of wolf spider Pirata subpiraticus Survivals and developmental duration of older spiderlings of Pirata subpiraticus after fed with BPH or Mycalesis gotama reared on KMD1 were not significantly different from those of the controls.

八、转Bt基因水稻对拟水狼蛛生长发育的影响取食在KMD1上饲养的褐飞虱若虫或稻眼蝶幼虫后，拟水狼蛛若蛛各龄的存活率与对照相比，无明显差异；六、七、八龄存活率和历期亦都无显著差异。

In order to study functions of glutathione S-transferase theta during preparation and synthesis of fibroin in Antheraea pernyi, expression of GSTT in silk glands of the fifth instar larvae was analyzed.

为明确柞蚕谷胱甘肽硫转移酶－theta在柞蚕丝素蛋白准备和合成过程中所起的作用，采用生物信息学的方法克隆了柞蚕GSTT基因，并分析其在5龄幼虫丝腺中的表达规律。

Autophagy is one of the major degradative pathways in eukaryotic cells,and it is the only one with the capacity to degrade entire organelles.

我们发现，细胞自我吞噬通路基因的突变体的体细胞在胚胎发育早期以及幼虫早期，会有P颗粒的异位聚集。

Analysis of PcG mutants shows that the PcG system represses genes required for anteroposterior, dorsoventral, and proximodistal patterning of imaginal discs and that it also represses cell cycle regulator genes.

对PcG突变体研究发现，PcG系统表达基因在幼虫发育的前端、背腹以及远端模式都是必须的，同时可抑制细胞分裂调节基因的活性。

And they mooch free meals in part by waggling their heads to beg for food like all the other ant grubs.

这些寄住在红蚁巢穴的蝴蝶毛虫，有时学着蚂蚁幼虫摇动自己的脑袋乞求免费的午餐。

As Bs grows, it produces binary toxin, Mtx and Cry48Aa/Cry49A, which have specific toxic effects on a variety of mosquito larvae. It is hence widely used in biological vector and mosquito control and considered a larvicidal solution that is non-toxic to human, animal, poultry and aquatic life and environmentally friendly.

Bs在生长发育过程中能产生对不同蚊幼虫具有特异性毒杀作用的二元毒素、Mtx毒素和Cry48Aa/Cry49A毒素，广泛应用于病媒蚊虫的生物控制中，被认为是一种对人、畜、禽、水生生物无毒，不污染环境的生物杀蚊幼制剂。

The contribution of soil microbiotic crusts to the diversity of insect species may be attributed to the facts that it stabilizes soil surface, improves soil environmental and there by provides suitable habitats and some food sources for the insects.

生物土壤结皮对荒漠昆虫多样性的贡献可能是由于稳定了土表、改善了植被系统中的土壤环境，为昆虫，特别是幼虫阶段提供相对适宜的土壤生境或部分食物来源。

Assulta are dosely related species in Noctuidae and their larvae are both polyphagous.

本项工作是在人工饲料中分别加入0.5％的烟碱、番茄苷、棉子酚、丹宁酸等饲养早期六龄的幼虫，测定它们对生长和食物利用的影响。

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。
