为沙棘木蠹蛾性引诱剂的开发和利用作准备 ,在内蒙古鄂尔多斯地区 ,就与沙棘木蠹蛾性引诱有关的几个生物生态学特性进行了研究 .结果表明 ,沙棘木蠹蛾 7月中旬进入羽化高峰期 ,1 5 :0 0— 1 8:0 0羽化量占日羽化总量的 90 % .雌蛾的求偶行为主要发生在 2 0 :0 0— 0 :0 0 .未观察到雌蛾多次交尾现象 ,偶尔可见雌蛾未交尾即产卵 .雌蛾寿命一般 2～ 7d ,平均 4d ;雄蛾寿命 3～ 8d ,平均 6d .处女雌蛾在林缘上风方向 30～ 1 0 0 0m都能诱到一定数量的雄蛾 .雌蛾的求偶行为表现出很强的时间节律 ,通过悬挂 7个处女雌蛾诱捕器连续观察发现 ,2 0 :0 0— 0 :0 0诱蛾量占日诱总量的 94 2 % ,1日龄处女雌蛾诱蛾量最多 ,随着处女雌蛾日龄的增加 ,诱蛾数量下降 .雌蛾腹部性腺体粗提物具有引诱雄蛾活力 ,交配雌蛾不再具有引诱雄蛾能力 .雌蛾的求偶暗期为 1～ 2h .沙棘木蠹蛾性诱特性符合蛾类的一般规律
In order to prepare for the development and utilization of the sex attractant of the seabuckthorn, the authors studied several ecophysiological characteristics related to the sexual attraction of the seabuckthorn (Cydia pumilai) in Erdos, Inner Mongolia.The results showed that the midrib At the peak of eclosion, the amount of eclosion accounted for 90% of the total number of feathering occurrences at 15: 0 0-1 8:0. The courtship behavior of female moth mainly occurred at 20: 0-0- 0: 0. Moth often cross the phenomenon, and occasionally visible female moths do not cross that is spawning.Female moth life is generally 2 ~ 7d, an average of 4d; male moth life of 3 ~ 8d, an average of 6d. Virgin virgin forest edge wind direction 30 ~ 100 0m can induce a certain number of male moths.The courtship behavior of the female moths showed a strong time rhythm.The continuous observation of the suspension of seven virgin female moths showed that the number of 20 ~ Accounting for 94.2% of the total amount of induced trapping, the number of induced moths was the highest in virgin female moths at 1 day old, and decreased with the increase of virgin female moths’ age. , Mating female moths no longer have the ability to induce male moths.The mating dark period of female moths is 1 ~ 2h.The sex trapping characteristics of seabuckthorn The general rules of co-moth
