| 摘 要： | 为了解斜纹夜蛾Spodoptera litura(Fabricius)配对后雌、雄成虫日活动行为节律,在室内人工气候室中配对饲养斜纹夜蛾,连续6 d观察成虫移动、静息、补充营养、产卵和交配5个行为类型。结果表明,在配对后6 d内,斜纹夜蛾的交配、产卵、移动、补充营养和停息行为所占比例均有明显变化,交配行为主要发生在配对后的前2 d,在配对后第6天成虫除偶尔补充营养外基本处于停息状态;交配行为有2个明显高峰期,即00∶00~01∶00(3.89%)和04∶00~05∶00(3.89%),雌、雄成虫移动行为日节律所占比例在03∶00~06∶00和补充营养行为日节律在03∶00~05∶00差异显著;成虫各行为分配频次最多的是停息行为,远高于其它行为,且各行为所占比例差异极显著,但雌、雄成虫之间无显著差异;雌、雄成虫运动行为几乎全部发生在暗期,且在不同时间段无显著差异;光、暗期各行为活动发生的比率差异显著;在暗期不同时间段,除雌蛾的移动行为、雄蛾的补充营养行为和交配行为无显著差异外,其它各种行为均差异显著。表明斜纹夜蛾雌、雄配对后移动、静息、补充营养、产卵和交配行为受成虫日龄影响较大,也受性别影响,表现出明显的日节律性。

| Abstract: | To study the diurnal behavioral rhythm and time budgets of Spodoptera litura (Fabricius) adults after paired, the adult behaviors, including moving (MV), resting (RT), mating (MT), supplementary nutrition (SN) and oviposition (OP), were observed for six consecutive days in artificial climatic chambers. The results showed that all behaviors of S. litura adults changed apparently in six consecutive days. MT-behavior occurred mainly in the 1st and 2nd day after paired. All were nearly RT in the 6th day except occasional SN. Two distinct MT behavioral peaks existed at 00:00-01:00 and 04:00-05:00. The rates of MV-behavior at 03:00-06:00 and SN-behavior at 03:00-05:00 were significantly different between females and males. RT-behavior accounted for the largest proportion and was far more than other behaviors. There was a significant difference in the diurnal time budget of adult behaviors, but no difference was observed between females and males. No significant difference was found in the motional behavior occurring mostly in scotophase between females and males in different periods. The proportion of all behaviors was significantly different between scotophase and photophase, not significantly different in different periods of scotophase except for MV-behaviors of females and MT- and SN-behavior of males. This study indicated that all behaviors of S. litura after paired were affected by adult age, and behavior rhythm was obvious and affected by gender. |
