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...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。展开更多
