信息素

The behavioral data robustly suggested that the 3 alkanols synergistically created a female attractant odor or male pheromone in the budgerigar and that bird uropygial glands have broader implications in sexual behavior than previously known.

张健旭研究组在性信息素，即费洛蒙研究方面获患了多个成果，曾以以11页的篇幅，在国际上首次论述了比小鼠更与人类接近的模式动物——大鼠的性信息素成分。

Four sorts of sex pheromones that were mixed at different ratios with three kinds of main sex pheromone components of seabuckthorn carpenter moth:-7-tetradecenyl acetate (Z7-14:Ac),-3-tetradecenyl acetate (E3-14:Ac) and-7-tetradecenyl acetate (E7-14:Ac), were experimented in the field. The results showed that four kinds of pheromones all had strong, attractive effects on male moths.

为比较沙棘木蠹蛾性信息素不同配方的诱集效果，该文利用人工合成的性信息素组分顺-7-十四碳烯乙酸酯(Z7-14：Ac)、反-3-十四碳烯乙酸酯(E3-14：Ac)和反-7-十四碳烯乙酸酯(E7-14：Ac)按照不同比例配置的4种配方进行了野外诱集试验。

The sex pheromone of click beetle was reviewed from the terms of distilled, isolated and identified, and its application status in this paper, to provide a guidance for the study of it.

本文对叩甲科昆虫性信息素的提取、分离鉴定及应用现状进行了综述，以期对我国在叩甲性信息素的研究提供一定指导。

The sexual behavior of chrysanthemum gall midge, Rhopalomyia longicauda (Diptera: Cecidomyiidae) such as the release of sex pheromone and calling behavior, were studied indoors and in a field trapping experiment. The sex pheromone was collected with an organic solvent aided by a glass container of charcoal-purified air. Laboratory observations showed that most males emerged 1-2 h before females.

为对菊花瘿蚊性信息素进行有效提取，本文对菊花瘿蚊成虫性行为进行了室内观察和田间诱捕试验，研究了菊花瘿蚊性信息素释放和求偶的行为规律，并用溶剂浸提和空气收集法提取了菊花瘿蚊性信息素。

It is improved to solve the prematurely and stagnation problems of traditional Ant Colony Optimization in the paper. First, mean value method is used to update pheromone to avoid premature convergence which leads to non-globally optimal solution. Second, Pheromone is updated by Best Track to speed the rate of convergence which will help to avoid locally optimal solution.

本文针对基本蚁群算法比较容易陷入早熟和停滞，对现有蚁群算法的信息素更新规则进行了改进，一是采用平均值法更新信息素，避免算法过早收敛于非全局最优解；二是采用最佳路径法更新信息素，可加快收敛速度，并使算法跳出局部最优解。

The research showed that:(1) Dendroctonus micans and Ips nitidus responded to pheromone of low concentration,which demonstrated that the olfactory response threshold of these two species to pheromone was very low,and the response value increased with the concentration.

研究结果表明：(1)云杉大小蠹与光臀八齿小蠹均能对其较低浓度的虫体信息素成分产生嗅觉反应，说明其对虫体信息素的感受阈值较低；且随着虫体信息素浓度的增大，反应值增加。

The sex pheromone-producing gland of Ancylis.sativa Liu is amodified intersegmental membrane as a dorsal bag between eighth and ninthabdominal segments.

对枣粘虫雌蛾性信息素腺体的扫描和透射电镜观察表明，枣粘虫性信息素腺体是由第八、九腹节间的节间膜特化而成，是位于背部的一个囊状结构，它由两部分构成，前部的方形囊状体和后部的三角形囊状体，二者之间有一突起的脊；雌蛾静止时，腺体随第八和第九腹节一起嵌缩于第七腹节内，求偶时，腹部末端外伸，腺体细胞表皮外露，释放性信息素；腺体细胞呈方形，其表面覆盖几丁质表皮，表皮顶端无孔；细胞核很大，呈椭圆形，由双层核膜包被，位于细胞中下部，内有丰富的染色质；细胞质内有丰富的内质网，其内还有大量的大小不等的脂肪滴，以及线粒体和溶酶体等细胞器。

Second,we set the database of morphological characteristics of intercepted and captured bark beetle during quarantine,and the last,we studied the molecular identification of 15 species.The results were showed as below.1.Application of bark beetle semiochemicals in timber quarantine1.1 EAG and walking responses of bark beetle to different semiochemicalsSemiochemicals which can induce the olfactory response and aggregation behavior of bark beetle include host volatile components,pheromones secreted by bark beetles itself or synthesized with host compounds by bark beetles,and the compounds released by tissue of decaying wood under the pressure of microorganism after bark beetle colonization.

信息化合物在小蠹虫检疫中的应用1.1小蠹虫对各种信息化合物的触角电位及嗅觉反应能诱发小蠹虫产生嗅觉反应，进而使之产生聚集行为的信息化合物有很多种，主要包括：树木的挥发性组分；小蠹虫自身产生的信息素和寄生后转化寄主化学物质合成的信息素统称虫体信息素以及树木被小蠹虫寄生后，其组织在微生物作用下释放的物质。

I am accused of being overreligious," she said in her quiet, frank manner,"but that does not prevent me thinking the children very cruel who obstinately commit such suicide.""

客人们在卡罗利娜·埃凯家里，举止就文雅一些，因为卡罗利娜的母亲治家很严厉。
