摘要
在不同温度下研究了赤拟谷盗Tribolium castaneum(Herbst)在固体物面、设定粮面、温度均匀的粮(小麦)柱和具有温度梯度粮柱内爬行扩散速度、起飞温度等。主要结果为:赤拟谷盗在17℃开始有爬行为,25℃开始有飞行行为,在15～25℃时水平爬行速度和15～20℃时竖直运动速度与温度呈显著正相关,在无障碍固体物面上的爬行速度为在粮面上速度的3.9～5.9倍,在水平粮柱内的扩散速度约为在竖直粮柱内扩散速度的1.2～3.1倍,赤拟谷盗的适宜起飞温度在25～30℃之间。
The influence of temperature on the dispersal rate and flight initiation of Tribolium castaneum（Herbst） adults was studied at different temperatures and on different substrates.The dispersal rate was monitored both on a solid surface and on wheat in a perspex groove at both uniform temperatures and over a temperature gradient.The results indicate that the minimum temperature that initiated crawling was 17℃ both on the solid surface and wheat bulk.The minimum temperature for flight initiation was 25 ℃ on both substrates.The dispersal rate of adults significantly increased with temperature within the range of 15-25℃ for horizontal movement,and within the range of 15-20℃ for vertical movement in the wheat column.The dispersal rate on the solid surface was 3.9-5.9 times higher than that on wheat.The dispersal rate in wheat columns was 1.2-3.1 times higher than in vertical columns without wheat.The ideal flight temperature was 25-30 ℃ for both male and female T.castaneum.
