棉铃虫

There were resembled mechanizm of the moth selecting and avoiding some monochromatic light or intensity level under two lights.

4棉铃虫蛾的趋光、避光反应行为具有相似的波长及光强度选择机制。

The life table analysis in the laboratory showed that there were no significant differences in survival rate, nympha duration, and fecundity between laboratory populations of aphids fed on Bt and non-Bt cotton.

对Bt棉在长江中游棉区对各种主要靶标及非靶标害虫影响的系统评价表明，在长江中游棉区种植Bt棉，将有助于控制该地区的棉铃虫和红铃虫的危害，减少棉田农药的使用次数，控制棉蚜的暴发，使棉田生态系统朝良性的方向发展。

A two-choice olfactometer was developed to determine the behavioural responses of adult cotton bollworm to plant volatiles.

发展了一种选择性嗅觉仪，用这种嗅觉仪测定了棉铃虫成虫对萎蔫的枫杨叶、新鲜的棉花叶、棉花花蕾、玉米叶及玉米花丝气味的反应。

This disseratation has confirmed that MAG stimulatedoviposition and oogenesis earlier.

棉铃虫MAG具有促进雌蛾更早产卵和卵子成熟的功能。

Electroantennogram responses of the generalist parasitoid Campoletis chlorideae Uchida to a range of plant volatiles and host pheromone gland compounds were investigated.

测试了棉铃虫齿唇姬蜂Campoletis chlorideae Uchida对58种植物挥发物和5种寄主性信息素腺体化合物的EAG反应。

In summary, FA is a sensitive indicator of the environmental stress and ecological risks induced in the parasitoid by exposure to Bt-cotton.

Bt棉对异色瓢虫也无影响，但在取食了转Bt基因棉的棉铃虫体内发育的寄生蜂较之对照表现为卵-结茧历期延长、茧重减轻、成虫寿命缩短，而其FA与个体结茧-出蜂历期呈显著正相关，表明FA是反映转Bt基因棉对斑痣悬茧蜂不利影响的敏感指标，可望成为转Bt基因棉生态风险的早期预警指标。

The ultrastructure studies show that the number of mitochondria in the motor neurons from resistant strain are higher than those of the susceptible strain, and the thickness of neural lamella and perineurium of resistant strain is thicker than those of the susceptible insects.

棉铃虫抗性种群、对照种群、同种群不同龄期幼虫以及同一个体胸、腹神经节的神经细胞体外培养时形态无明显差异，但抗性品系幼虫运动神经元内线粒体明显增多，且神经围鞘与神经节膜厚度之比明显增加。

The results were as follows:(1) Monochromatic light in different wavelenth could induce phototaxis behaviour reaction of the CBW moth with different level. According to the response rate of it, some peaks appeared in their spectral behavior response curve, two of them were located at 483nm and 340nm, others located in 400nm,538nm and 605nm respectively. The peak response in 483nm agreed well with ERGs result.

峁允？：(1)一定时间暗适应的棉铃虫蛾对单色光和白光刺激均具有趋光行为反应，依其趋光反应率大小，其光谱反应曲线在340 -605nm波谱范围内，表现为大小较复杂的几个峰，其中两个峰分别在蓝光区483nm、紫外340nm ，另在近紫外的400nm、绿黄光区的538nm有峰。

The mechanism of photosensitivity and phototaxis was studied with optical andelectrophysiological method. The results are as follows:1 among three kinds of Chysopa peral. of the compound eyes show little daily change in Chrysopa sinica Tjedar .The model and color of psesudpopupil show significant daily change in Chrysopa septempzhbybimctata Wesmacl and Chrysopa formosa Brauer, color and diameter of the psesudpopupil of the compound eyes in Chrysopa septempunctata Wesmacl make rapid change at noon, afternoon ,night are similar ,but make little change in the morning and the next morning. Diameter of psesudpopupil of compound eyes is the biggest in the afternoon, which of Chrysopa formosa Brauer, is the biggest at noon.

本文应用光学及电生理学方法对棉铃虫优势种天敌—中华草蛉、大草蛉和丽草蛉3种草蛉的感光和趋光机制进行了研究，主要研究结果如下： 1、中华草蛉、大草蛉、丽草蛉复眼伪瞳孔大小、颜色昼夜间有节律性变化，且种间具有不同的变化模式。3种草蛉中，中华草蛉复伪瞳孔大小昼夜节律变化不明显，其模式和颜色上亦基本无变化，中间为一小黑点，其外围是绿色，最外层为红色，形状为正六边形：大草蛉、丽草蛉的复眼伪瞳孔大小昼夜间不同，大草蛉的复眼伪瞳孔在中午、下午、晚上变大，早晨和次日早晨基本一致，但次日早晨稍小些。

This paper reports the results of studies on the nuclear polyhedrosis virus-of the cotton bollworm Heliothis armigera.

自1973—1974年以来，在湖北荆州地区微生物站筛选出一批棉铃虫病毒毒株，其毒力均为80％以上，有的高达100％。

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。
