拥挤度和光照条件对赤拟谷盗成虫逃逸行为的影响

Effects of Overcrowding and Light Conditions on Escape Behavior of Tribolium castaneum Adults

【目的】研究赤拟谷盗成虫逃逸活动规律和赤拟谷盗种群控制方法。【方法】以赤拟谷盗成虫为研究对象,分析赤拟谷盗成虫逐日逃逸现象,研究拥挤度、光照条件对其逃逸行为的影响。【结果】全黑暗和自然光周期条件下,赤拟谷盗成虫的逐日逃逸数量与拥挤度呈正相关;拥挤度达到50头/皿以上时,赤拟谷盗成虫逃逸行为频繁,且黑暗条件下的逃逸数量显著小于光照条件。【结论】光照对赤拟谷盗成虫的逃逸行为具有刺激作用,拥挤度的增加,有助于成虫逃逸。

【Objective】 To clarify the escape activity of Tribolium castaneum adults movement behavior and study the control method of the population.【Method】 Taking the adults of Tribolium castaneum as the research object, the daily escape phenomenon was observed, and the effects of congestion and light conditions on the escape behavior were studied preliminarily.【Result】 There were significant differences between the amount of daily escape of Tribolium castaneum in the condition of light and dark. The amount of Tribolium castaneum adult daily escape was positively correlated with the crowd, which was indicated by the different numbers of insects in one plate;When the degree of overcrowding was more than 50 heads or more per plate , the movement of Tribolium castaneum adults was frequent, and the number of escapes in dark condition was significantly fewer than that under light condition.【Conclusion】 The light can stimulate the escape behavior of the adults, and the increase of congestion is helpful to the escape of the adults.
