查询词典 budworm

Remote sensing for the detection of pest damage is an important element in forest management, This study describes the application of Landsat-5 Thematic Mapper digital data, using the Perceptron image analysis system, for the detection of western spruce budworm damage on Douglas fir stands near Cache Creek, British Columbia, Canada.

森林虫害监测是森林经营管理中的一个重要内容，为此作者利用陆地卫星第5号的主题成图仪数据，在加拿大不列颠哥伦比亚省卡奇河试验区对花旗松林被云杉茅卷蛾危害的状况进行了监测。

CDNA fragment of cadherin-like protein gene in the fifth instar larva of oriental tobacco budworm was amplified using degeneracy primers and RT-PCR technique, and the target fragment was further sequenced after being cloned into pMD18-T vector plasmid.

本研究以烟夜蛾五龄幼虫中肠的总RNA为模板，根据已经克隆的其他昆虫的类钙粘蛋白基因序列设计引物，利用RT-PCR技术扩增出了烟夜蛾类钙粘蛋白基因的cDNA片段，将其连接到pMD18-T载体，转化大肠杆菌后筛选阳性克隆并进行序列测定，测序得到的1335bP的片断编码444个氨基酸残基。

Insect resistance to Bt toxin is related with the variation of cadherin-like protein gene.cDNA fragment of cadherin-like protein gene in the fifth instar larva of oriental tobacco budworm was amplified using degeneracy primers and RT-PCR technique,and the target fragment was further sequenced after being cloned into pMD18-T vector plasmid.

本研究以烟夜蛾五龄幼虫中肠的总RNA为模板，根据已经克隆的其他昆虫的类钙粘蛋白基因序列设计引物，利用RT-PCR技术扩增出了烟夜蛾类钙粘蛋白基因的cDNA片段，将其连接到pMD18-T载体，转化大肠杆菌后筛选阳性克隆并进行序列测定，测序得到的1 335 bp的片断编码444个氨基酸残基。

With primers designed according to sequence(AY052417) of diapause pupae of oriental tobacco budworm registered on GenBank, a double-strand cDNA fragment of DH gene was obtained from RT-PCR amplification and was further cloned into pGEM-T Easy vector.

根据GenBank发表序列(AY052417)设计引物，以烟夜蛾(Helicoverpa assulta Guenée)滞育蛹为材料，利用RT-PCR技术扩增到滞育激素(diapause hormone，DH)cDNA，并通过TA克隆的方法将其克隆至pGEM-T Easy载体上，对目的基因进行测序，并利用设计的酶切位点将目的基因从T载体上切下。

Aquatic or marsh-growing fern allies; known to have existed since the Cenozoic; sometimes included in Lycopodiales.

生活于水中或湿地的蕨类；从新生代生存至今；有时归于石松目之中。

The engine was uprated from a 90hp Franklin to a 125hp Lycoming.

改良过的引擎是从90hp到125hp莱康明富兰克林。
