  • 简介:在决定潜在的分发并且交配个人的成功的外来、内在的因素的相对重要性的理解为成功的监视和害虫种类的管理是批评的。用地观察和一个将关入笼中的地实验的联合,我们在交配聚集并且在buprestid甲壳虫Capnodistenebrionis交配成功的形成上探索了环境、单个的变化的角色(Linnaeus,1767),石头水果树的害虫种。我们的地观察表明聚集的形成被环境因素的一个范围包括温度,光周期,和人口密度影响。然而,聚集不在随机并且是更可能的与太阳的放射和这样更高的温度的最高的发生发生在植物的节上。从我们的实验与的数据使甲壳虫觉得身困笼中这块地进一步显示这种的繁殖行为与温度变化。发生的成功的交配的概率也是断然与男、女的尺寸有关。C的女性。tenebrionis配偶若干次在一个4-h时期上,但是通常不与一样的男性一起。从这些研究获得的信息是有用的为害虫控制定义最适当的时间,特别采用防碍复制的策略。
