Xylostella. The synergism ability with dipping method l4as more obvious than with contact and stomach method. Among the six adjuvants, copper abietate, 1427 and 412103 had 3.71, 2.82 and 2.72-fold synergism ratio, respectively.

结果表明：在400mg/L以下，各阳离子助剂单独使用对小菜蛾3龄幼虫均无生物活性，但可明显提高阿维菌素对小菜蛾的药效。

We examined the infection of Paecilomyces fumosoroseus via electron microscopy scan and pathogenicity of P. fumosoroseus conidia powder, conidia suspension liquid and conidia broth. Results show more conidia in acanthoid surface topography than in spinous surface topography.

采用扫描电镜观察玫烟色拟青霉分生孢子在小菜蛾幼虫体表的萌发和侵染过程及玫烟色拟青霉孢子粉、孢子悬浮液和孢子培养液对小菜蛾幼虫的致病力。

By means of the life table of acting factors combinations and the theory of modern population system control,this paper evaluated the efficacy of different combinations of application dosage and times of granulosis virus on Plutella xylostella control.

利用作用因子组配的生命表和种群系统控制理论，模拟了小菜蛾颗粒体病毒不同浓度和不同施用次数组合对菜心地小菜蛾自然种群的控制作用。

The result in efficacy trials against Plutella xylostella indicated that some kinds of photoprotecting avermectin had the most dramatic effect on the 3 day after application.

对小菜蛾的田间药效表明，几种光保护型阿维菌素对小菜蛾的防效在3d后差异显著，混合UV-P+BHA的阿维菌素在1、3和7d的防效分别为84.78％、95.17％和98.50％。

Temperature showed significant effect on the toxicity of avermectin to the second instar larva of Plutella xylostella.The toxicity become greater as temperature ranged from 15 -~-- 32 C .

温度对阿维菌素的毒力有较大的影响，在15～32℃温度范围内，阿维菌素对小菜蛾幼虫的毒力随着温度的升高而增强，温度从15℃上升到32℃，阿维菌素对小菜蛾幼虫的毒力增加了32.35倍。

Plant volatiles allyl isothiocyanate , Z-3-hexen-1-ol , and Z-3-hexenyl acetate can attract DBM both in Hubei and in Vietnam.

中国小菜蛾诱芯在越南可以控制小菜蛾的危害，减少农药施用次数约4-5次。

The changes in targets may decrease the effect of NTX insecticide; SI04 sequence has relationship with the propagation of diamondback moth.

它们的改变可能会影响到沙蚕毒素的作用效果；S104序列则可能与小菜蛾的生殖方面相关，目前认为抗药性的不稳定性与抗性小菜蛾的繁殖率降低有关。

Taken together, compared with the susceptible strain, the resistance strai ns have no obvious changes in karyotype but have distinct difference in DNA level, which suggests that insecticide resistance is related to the changes hi gen omic DNA in diamondback moth.

从上面的结果看来，与敏感品系相比，三种抗性品系小菜蛾的核型没有发生明显的变化，但在DNA水平上存在明显的差异，说明小菜蛾的抗药性与基因组DNA的变化有关。

The orientation of diamondback moth and Cotesia plutella to the vegetable volatiles was investigated using Y-tube olfactory in the lab.

采用&Y&型管嗅觉仪，在实验室条件下，对十字花科蔬菜-小菜蛾-小菜蛾绒茧蜂系统中，害虫和寄生蜂对挥发物的定向行为进行了初步的研究。

Methods: Five patients with parkinsonism or dystonia were assigned to general anesthesia using an modified endotracheal tube.

本实验依照人体实验之相关规定进行，五位患有帕金森氏症或肌张力异常的病人接受神经立体定位手术。
