摘　　要：国槐尺蠖(semiothisa cinerearia Bremer et Grey)的性信息素腺体位置通过触角电位、扫描电镜和组织学三种研究技术进行了检查。触角电位证明性信息素腺体位于产卵器。扫描电镜确定在雌蛾腹部第Ⅷ和Ⅸ—Ⅹ节之间的节间膜背面有一囊状结构。触角电位进一步证明这一囊状结构为性信息素腺体。腺体横切显示性信息素腺体细胞特征为核大,细胞体呈柱状,细胞质内有小空泡。触角电位证明雌蛾在暗周期(20:00,21:00和22:00)产生的性信息素比在光周期(8:00、9:00和10:00)多。风洞试验显示雄蛾在暗周期(21:00)比在光周期(9:00)对性信息素提取物的行为反应强烈。田间试验证明性信息素腺体提取物具有诱蛾活性。上述结果为国槐尺蠖性信息素的化学分离和鉴定提供了基础。The location and structure of the sex pheromone glands in the female moths of the Sophora geometrid Semiothisa cinerearia Bremer et Grey were studied through the electroanten-nogram (EAG) technique,scanning electro microscopy (SEM) and histological examination.The EAG of the male moths in response to the extracts from the different parts of the female body pointed to the area on the ovipositor as the site of sex pheromone gland.SEM examination confirmed that there was a saccate structure located at the dorsal intersegmental membrane between abdominal segment Ⅷ and Ⅺ-Ⅹ (papilla analis) of the female moth.The saccate structure was further identified as the sex pheromone gland by EAG technique.Histological examination on the sex pheromone gland showed that the glandular cells were cubiform with large nuclei.The EAG data showed that the female moth produced more sex pheromone at scotophase than at photophase,and the wind tunnel experiments demonstrated that the male moth responded to the sex pheromone extracts also stronger at scotophase.Experiments of trapping in the field showed that the extracts of sex pheromone glands were attractive to the male moths.These results have laid the basis for chemical isolation and identification of the sex pheromone of this species for further work.
