查询词典 lepidopteran

Bt cotton and corn may affect natural enemies indirectly by decreasing the population of lepidopteran insects that serve as hosts of parasitoids or predators. Population densities of predators in Bt fields were significantly higher than those in non-Bt fields treated with insecticides for control of target pests.

杀虫剂用量的减少，降低了对天敌的杀伤力，Bt田中捕食性天敌的种类和数量均显著高于常规施药田；但Bt田内靶标害虫数量的减少和质量的降低，在一定程度上影响了寄生性天敌的种类和数量。

Vip3A with a broad-spectrum insecticidal activity to many lepidopteran insects shares no sequence similarity with the known insecticidal crystal proteins.

Vip3对鳞翅目昆虫具有广谱杀虫活性，该蛋白广泛存在于Bt中，与已知杀虫晶体蛋白ICPs没有序列相似性。

The vip3A genes amplified from wild-type Bt strains S184 and 611 with different levels of activity against lepidopteran insect larvae were cloned into pGEM-T Easy vector. Alignment of these 2 putative Vip3A proteins with 8 others showed that vip3A genes are highly conservative.

从以上菌株中挑选2个对夜蛾科害虫具有较高和较低毒力的菌株，即S184和611，分别进行vip3A基因的克隆和测序，再已报道的其它8个vip3A基因进行核苷酸和氨基酸序列比较，结果表明，vip3A是一个极其保守的基因。

Phylogenetic tree derived from all known EPVs spheroidin gene indicates that the order of the EPV host is in relationship with the genus of corresponding EPV, which agrees with a recent point that "Lepidopteran EPVs and Orthopteran EPVs should be divided into two distinct genus".

对已知的几种昆虫痘病毒球状体蛋白基因做系统进化树，结果显示，以病毒寄主的昆虫分类目作为昆虫痘病毒的分属依据，更符合分子水平的分析结果，也与近年来许多学者所提出的"将鳞翅目与直翅目昆虫痘病毒分为2个不同的属"的观点相一致。

Based on the combined dataset of nucleotide and amino acid sequences of 13 protein coding genes,using the maximum likelihood and Bayesian inference methods to reconstruct the phylogenetic relationship of fifteen species of lepidopteran insects,The resulst showed the same topologies and supported a close relationship between the Geometroidea,Noctuoidea and Bombycoidea.This result deviates from the traditional view.

基于线粒体基因组13个蛋白质编码基因的核苷酸序列及氨基酸序列的联合数据集构建了15种鳞翅目昆虫的系统树，采用BI和ML分析方法建树，所得拓扑结构类似，都显示蚕蛾总科，尺蠖蛾总科和夜蛾总科关系较近，结果与前人研究的结果不完全一致。

A Bacillus thuringiensis strain Bt25 with high insecticidal activity against several primary lepidopteran pests in China was identified by PCR-RFLP system, and subsequently a novel cry1Aa gene was cloned from it by PCR techniques.

Bt25是中国自行分离的对小菜蛾具有高毒力的苏云金芽孢杆菌，经PCR-RFLP鉴定含有cry1Aa基因。

It was found that GUS reaction and PCR amplification test for Bt gene were positive with all RIMY46 and II32A/RIMY46 hybrid plants, and all lines were highly resistant to lepidopteran insects.

经考察，RIMY46及其所配杂种1132A/RIMY46的GUS反应和PCR检测均为阳性，且高抗螟虫。

The GeneParity Plot analysis showed that PiraGV genome shared the highest collinearityof gene order with tortricid-infecting CpGV, ChocGV and CrleGV than to GVsthat infect other lepidopteran families and NPVs.

GeneParityPlot分析显示：PiraGV基因组的基因内容和排列与感染卷叶蛾科的CpGV，ChocGV和CrleGV基因组呈现了高度的共线性关系。

In order to enhance its resistance to bacterial blightand lepidopteran such as leaffolder, striped stem borer and yellow stem borer etc, we intergessed Xa21 and Bt genes into the genetic background of 93-11 by backcross scheme, combining with molecular marker-assisted selection and phenotypic selection. Through three backcross and two self generations, eight families that have homozygous Xa21 and Bt genes were obtained in the BC3F3 families. Two families show higher recovery percentage of 93-11 even up to 90.59%.

为了进一步提高其对白叶枯病的抗性、同时增加其对水稻鳞翅目害虫（如稻纵卷叶螟、二化螟和三化螟等）抗性，利用常规回交育种方法和结合分子标记辅助选择将Xa21基因和Bt基因同时导入93-11中，在BC3F3家系中筛选到8个家系含纯合的Xa21基因和Bt基因，其中有两个家系与93-11比较其遗传背景的回复率很高，达到90.59%。

But we don't care about Battlegrounds.

但我们并不在乎沙场中的显露。

Ah! don't mention it, the butcher's shop is a horror.

啊！不用提了。提到肉，真是糟透了。
