桃蚜

With a dose of 106 conidia/ml concentration the LT50s for the 6 isolates ranged from 3.7 to 8.9 days.

结果表明，球孢白僵菌的一些菌株对桃蚜有较强的致死作用。

Among three microsatellite primers usually used in the aphid and three primers used in the study of the Aedes japonicus (Diptera:Culicidae), finally four primers were selected to amplify the different samples of the green peach aphid. The result showed that DNA samples could be well amplified.

在三条常用的蚜虫微卫星引物和三条用于对日本伊蚊Aedes japonicus 研究所用的引物中，最终选取了33.15 核心序列、4、8G、8G 四条引物对桃蚜的不同样本进行扩增，结果表明扩增效果较好。

During the first 7-day period, 639 alates died from mycoses caused by several obligate aphid pathogens in the Entomophthorales, representing a primary infection rate of 27.2% among the air-trapped alates.

自2002年10月至2005年5月在杭州上空诱获桃蚜的迁飞性有翅蚜2351头，将其带回室内在(21±1)℃和12L：12D条件下单头饲养12d，其中639头在定殖后7d内发病死亡，初始感染率达27.2%。

Five potato lines were selected for peach aphid resistanceidentification, and the result showed that the effect of insect-resistance was apparent.

通过对转GNA马铃薯进行抗蚜虫鉴定，结果证明转GNA马铃薯对桃蚜具有显著的抗性作用。

On the basis of many times of experiments, A optimized reaction system about the microsatellite PCR amplification and partial COⅠ-Ⅱgene amplification of the green peach aphid was proposed.

在多次实验摸索的基础上，优化了桃蚜微卫星扩增和mtDNA COⅠ-Ⅱ部分序列特异扩增的反应体系。

It is the first time of using the microsatellite primer-PCR and partial gene of mtDNA COⅠ-Ⅱamplification to analyze genetic diversity of host bio-type and body colour bio-type and to probe out the changing mechanism of body colour on green peach aphid in China.

本论文在国内首次运用微卫星引物PCR 扩增和mtDNA COⅠ-Ⅱ部分序列特异扩增的方法对桃蚜寄主生物型和体色生物型的遗传分化和体色变化机理进行了研究。

At the mean time higher dose increased its endure tolerance. 2. Extracting DNA from small sized insect proved that the size of the green peach aphid's genome DNA is about 21 kb.

此结果从分子水平证明处理F2代桃蚜的DNA发生了变异，揭示出紫外诱导可遗传的变异，且变异大小是由辐射时间和辐射强度共同决定。

According to the Marker (EcoR1-HindⅢ), the size of the green peach aphid's genome DNA is about 21 kb.

根据分子量Marker(EcoR1-HindⅢ)，桃蚜基因组DNA 的大小在21kb 左右。

On the basis of many times of experiments, A optimized reaction system about the microsatellite PCR amplification and partial COⅠ-Ⅱgene amplification of the green peach aphid was proposed. 3. It is clear that the result of polymorphic bands shows the abundance among the aphids after different UV radiation with three primers.

遗传多样性指标的方差分析结果表明，对于平均多态位点率，2 h处理是平均多态位点率的临界值，超过2 h， F2代平均多态位点率发生显著变异；对于平均基因多样度，对照与不同时间处理间差异显著；研究结果也表明低剂量紫外照射可增加蚜虫的免疫性，高剂量辐射则导致桃蚜的基因发生变异。

After comparison of different complete artificial diets, semi-artificial diets and practical diets, a complete artificial diet was determined that could be employed to rear the green peach aphid, Myzus persicae, continuously for several generatiuons.

通过对多种全纯饲料、半纯饲料和实用饲料的比较，确定了一种可连续多代饲养桃蚜的全纯饲料。

Singer Leona Lewis and former Led Zeppelin guitarist Jimmy Page emerged as the bus transformed into a grass-covered carnival float, and the pair combined for a rendition of "Whole Lotta Love".

歌手leona刘易斯和前率领的飞艇的吉他手吉米页出现巴士转化为基层所涵盖的嘉年华花车，和一双合并为一移交&整个lotta爱&。

This is Kate, and that's Erin.
