幼虫的

However, they have their respective shortcomings in mosquitocidal spectrum, persisting and resist-mosquito management. In this research, the mosquitocidal toxin genes cry4Ba and cry11Aa from Bacillus thuringiensis and btx gene from Bacillus sphaericus were co-expressed.cry4Aa,cry4Ba and cry11Aa genes were also co-expressed with btx gene seperatedly and in combination.The constructed recombinants had a high toxicity against susceptible and resistant mosquito.

本研究将苏云金杆菌以色列亚种的杀蚊毒素基因cry4Ba和cry11Aa与球形芽胞杆菌的二元毒素基因btx两种杀蚊菌的杀蚊毒素基因进行了重组，将Bti杀蚊毒素基因cry4Aa， cry4Ba， cry11Aa及Bs的杀蚊毒素基因btx单独或组合表达，所得工程菌株对敏感和抗性库蚊的毒力均有提高，不仅提高了杀蚊毒力，扩大了杀蚊谱，而且部分克服了蚊幼虫对Bs的抗性。

The growth and survival of Mytilus galloprovincialis post-larvae metamorphosed using different chemical compounds were investigated in this study to identify potential inducers in aquaculture and antifouling and biofouling researches.

中文摘要：在以往实验的基础上，跟踪调查了筛选出的化学诱导物质对紫贻贝幼虫变态后的生长和成活率的影响，并比较了其与相同条件下自然诱导物、微生物膜诱导后的稚贝的生长和成活率。

The emergence of adult started to occur in the last ten days of May and would last to the first ten days of July, and then went into a stage of rampantly damaged to the bamboos. The adults could mate multi-time each other in all life except the dormancy.

卵和幼虫在横向上的聚集性强于其在纵向上的聚集性，而蛹和成虫在横向上的聚集性则明显弱于其在纵向上的聚集性，种群在0-3 m尺度内的分布没有明显规律性。

To clarify the acetylcholinesterase changes among different developmental stages of Tribolium castaneum, the toxicological and biochemical characterizations of AChE in 10-d larvae, 20-d larvae, pupae and adults were investigated, respectively with the microplate reader method.

为了阐明赤拟谷盗体内乙酰胆碱酯酶在其各虫态间的变化关系，以期为该虫的综合治理提供一定的理论依据，本试验采用微量滴度酶标板法，分别对其10d龄和20d龄幼虫、蛹及成虫体内AChE的生化及毒理学特性进行了较为系统的研究。

Immature of its kind; especially being or characteristic of immature insects in the newly hatched wormlike feeding stage.

该种类的不成熟时期的；尤其是在或具有刚被孵化的像蠕虫一样饲养的幼虫时期的特征的。

This ragtag group consists of the brilliant but insect-headed Dr. Cockroach, Ph.D.; the macho half-ape, half-fish The Missing Link; the gelatinous and indestructible B.O.B.; and the 350-foot grub called Insectosaurus.

这组由乌合之众的辉煌，但昆虫博士为首蟑螂，博士学位；的马乔半猿半鱼的缺失环节；的胶质和坚不可摧巴鲁达；和350英尺的幼虫称为Insectosaurus 。

The results indicated that the histone deacetylase inhibitors had effects on the morphology of the polytene chromosomes.

2，利用RT-PCR技术，对去乙酰化酶抑制剂处理后的果蝇的热休克基因的表达水平进行检测，结果表明经组蛋白去乙酰化酶抑制剂处理后的果蝇幼虫，其热休克基因的表达高于基础水平，也就是说去乙酰化酶抑制剂诱导了热休克基因的表达。

Based on this result, it is concluded that the change of acetylation level at the loci of hsp, mediated by histone deacetylase inhibitors, exertsimportant functions in hsp gene transcription.3, After immunolabeling with anti acelated-lysine monoclonal antibody on the polytene chromosomes of heat shocked flies, fluorescence signals were detected at the hsp loci.

3，利用抗乙酰化赖氨酸的单克隆抗体对热激处理后的果蝇幼虫多线染色体进行的免疫荧光实验结果表明在热休克诱导的hsp70基因的表达中存在乙酞化修饰。

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。
