选AB是因为这题问的是人类对蝴蝶雌雄的识别= =很BT的语言游戏
昆虫间谈情说爱并不需语言，通常通过化学物质来传递信息，沟通思想。大多数情况下，雌成虫成熟后，即分泌一种特殊的易挥发的信号化合物，刊登征婚广告。而雄成虫则靠自己灵敏的嗅觉，感受信息，并根据信息的方位去寻找自己的意中人。发布日期：日&|&标签：&

摘要:（该内容经过伪原创处理，请直接查看目录）甜菜夜蛾Spodoptera exigua是一种主要的农业益虫,常迸发伤害,轻易发生抗药性,灯光诱杀与性引导剂诱杀常作为其防治的主要办法。两种诱捕防治技巧也被集成运用来对甜菜夜蛾停止防控,但防控后果却鲜有评价。田间诱捕防治时发明,甜菜夜蛾对灯光及性引导剂行动反响表示出节律性且上灯存在显著的雄性偏好。是以,本课题从提醒甜菜夜蛾上灯节律及性别偏好发生的能够机制、明白甜菜夜蛾雄虫交配通信体系调控程度的角度展开研讨,评价灯光与性引导剂集成运用对甜菜夜蛾的防控后果,为进步诱捕效力供给实际基本,对加倍经济、有用天时用灯光与性诱杀防治益虫具有必定的指点意义。重要成果以下：1.甜菜夜蛾上灯节律及雄性偏好发生机制田间灯光诱捕试验发明,甜菜夜蛾扑灯具有显著的节律性和雄性偏好,在全部产生期,上灯雄虫量均高于雌虫,雌虫重要在上子夜扑灯,雄虫重要鄙人子夜扑灯。田间收集幼虫豢养至化蛹,剖析成果注解甜菜夜蛾天然种群牝牡性比相符实际比值1：1。雌虫扑灯节律与其产卵节律明显相干,且扑灯雌虫重要为己交配雌虫；雄虫扑灯节律与交配节律明显相干。室内趋光行动试验注解,雄虫与己交配雌虫的上灯率无明显差别,二者均明显高于未交配雌虫的上灯率,且室内牝牡虫扑灯节律与室外相分歧。由试验成果剖析推想,能够因为已交配雌虫在上子夜产卵,运动性加强,所以上子夜被诱捕；雄虫重要鄙人子夜运动追求雌虫交配,故诱捕岑岭鄙人子夜,出现出显著的节律性。未交配雌虫的运动性弱,上灯率较低,是以,从灯光诱捕总量剖析,构成了灯下雄虫偏多的景象。2.甜菜夜蛾雄虫对性信息素行动反响节律调控程度很多虫豸中雄虫对性信息素的行动反响表示出显著的节律性,但是这类节律调控机制尚不清晰。本课题经由过程研讨甜菜夜蛾对性信息素的行动反响节律和飞翔运动节律来说明其对性信息素行动反响调控程度。2011年7月-8月田间诱捕试验发明,灯光和性引导剂对甜菜夜蛾诱捕岑岭均涌现鄙人子夜,且两诱捕节律间存在显著的相干性。触角电位丈量发明,在LD15：9光周期前提下,触角每小时对性信息素的反响电位值无明显差别。在27℃,LD159、连续暗期第一天(DDl)、连续暗期第二天(DD2)前提下雄虫的运动岑岭重要在暗期和客观光期,在雷同的温度和光周期前提下,风洞中雄虫对性信息素的行动反响产生在暗期和客观光期。Pearson相干性剖析注解,在LD15：9、连续暗期第一天(DD1)、连续暗期第二天(DD2)前提下,雄虫的运动节律和对性信息素的行动反响节律均表示出明显的相干性。该研讨成果注解,甜菜夜蛾雄虫对性信息素的行动反响与其飞翔运动节律相耦合,且这两种节律行动均由内源性生物钟调控。3.灯光诱杀与性引导剂集成运用对甜菜夜蛾防控后果评价诱捕成果显示,频振灯零丁应用可诱捕更多的雌虫,频振灯上吊挂性诱芯仿佛克制了光源对雌虫的诱捕却可明显增长雄虫的诱捕量,且诱捕的雄虫量高于离开应用时诱捕雄虫的总和。是以,当频振灯与性引导剂分离应用时可诱到更多的雌虫,诱捕雄虫数目绝对削减。性信息素搅扰交配试验发明,性信息素在有用规模内可明显搅扰甜菜夜蛾的交配。雌虫的交配与产卵在种群繁衍中占领侧重要位置。综合剖析注解,杀虫灯与性信息素离开零丁应用为一种较好的应用方法。该课题深刻研讨了甜菜夜蛾对光与性信息素行动反响的调控机制,为进一步优化甜菜夜蛾灯光诱杀与性诱捕防治技巧,勤俭本钱,高效防治供给实际基本,对蔬菜地益虫综合防治有普遍的自创意义和适用价值。
Abstract:Beet armyworm, Spodoptera exigua is a major agricultural pests, often burst damage, prone to drug resistance, light trapping and guiding trapping agent is often used as a primary means of prevention and treatment of the. Two kinds of trapping techniques are also applied to the integrated control of beet armyworm stop control, but rarely evaluate consequences of prevention and control. Field trapping control of the invention, beet armyworm to light and guide agent action response expressed rhythm and light exist significant male preference. This topic from alerting light rhythm and sex preference in the beet armyworm can mechanism, understand Spodoptera exigua male mating communication system that regulates the degree of angle discussion, evaluation and light guide agent to integrate the prevention and control of beet armyworm consequences, for progress trapping efficiency to provide basic theory, to double economic and useful days with lights and trap to control insect pests has certain directive significance. Important results are as follows: 1. Beet armyworm light rhythm and male preference occurrence mechanism field light trapping test method, beet armyworm flapping lamp with significant rhythm and male preference, in the whole period of generation, the light quantity of male were higher than females, females important in midnight flapping lamp, male important issueing midnight flapping lamp. The feeding larvae were collected to pupation, analysis of the results of annotation of beet armyworm in natural populations than male and female coincided with the actual ratio of 1:1. Females flutter light rhythm and spawning rhythm was coherent and flapping lamp female important himself mating females. Males were flapping light rhythm and mating rhythm obvious coherence. Indoor light action test annotation chemotactic, males and females mated lamp was no significant difference, both were significantly higher than those of unmated females lights on the rate and indoor male and female worm flutter light rhythm and outdoor phase differences. By the test results analysis suppose, can because of mated females laying eggs in the midnight, strengthen the movement, so
male important issueing midnight movement pursuit of female mating, thus trapping Cen Ling in the midnight, significant rhythm. Unmated females movement is weak, light rate is low, is to, from the light trapping total analysis, constitute the lamp male side of the scene. 2. Beet armyworm males of information element action response rhythm control level in a lot of insects in males of prime action response expressed significant rhythm, but this kind of rhythm control mechanism is not clear. This topic through the beet armyworm research process of the action reaction rhythm and flying rhythmic motion to illustrate the sex pheromone action response control level. July 2011 August field trapping trials of invention, light and directing agent of the beet armyworm trapping Cen Lingjun emerge in midnight, and between two trap rhythm exists significant coherence. In the premise of the LD15:9 light cycle, there is no obvious difference in the value of the response of the antenna with the antenna. In 27 DEG C, LD159, continuous dark period in the first day (DDl) continuous dark the next day (DD2) premise under male sports Cen Ling important during the scotophase and the objective light period and under the same temperature and photoperiod on the premise that males in the wind tunnel of prime action response produced in the dark phase and tourist period. Pearson correlation analysis of annotations in the LD15:9, continuous dark period on the first day (dd1), continuous dark period (DD2) prior to the next day, male rhythmic movement and of the action reaction rhythm expressed obvious coherence. The research notes, beet armyworm males to the action reaction and fly are coupled with the rhythmic motion, and these two rhythm action by an endogenous circadian clock regulation. 3. Light trapping and guiding agent integrated application on the prevention and control of beet armyworm consequence assessment trapping results display, lamp of frequency vibration Lingding application can be trapping more females, the lamp of frequency vibration hanging hanging induced restraint core if light source to the female trapping can be significantly increased male of trapping volume and trapping the quantity of male higher than leaving the application when trapping males, the sum. So, when the lamp of frequency vibration and guide agent application can be induced to separate more females, the number of absolute cuts in trap. The sex pheromone disturbed mating test method, sex pheromone can be useful in the scale of mating significantly disturbed beet armyworm. Female mating and spawning in the population occupied an important position in the side. Comprehensive analysis of notes, insecticidal lamp with sex pheromone left alone application is an effective method of application. The paper deeply research the beet armyworm to light and information element action response regulation mechanism, in order to further optimize the beet armyworm light trapping and trap prevention techniques, diligence and cost, efficient control of supply basic theory, the integrated control of vegetable pests have generally self creative meaning and applied value. ...
