目的:研究不同色光和白光刺激下蝗虫成虫和虫蝻的趋光、避光行为反应及其与光强度之间的关系,为蝗虫的光电诱导治理提供理论基础。方法:将蝗虫放置于行为反应试验箱中,运用行为试验方法,观察测定不同光谱和光强下蝗虫的波长选择响应及其运动速度。结果:①蝗虫的趋光、避光反应行为具有相反的波长选择机制,在紫光、蓝光、绿光等短波段趋光性较强,在红光、橙光等长波段趋光性较弱;②低光强度范围内,蝗虫的趋光反应率随光强度的增强而增大,至一定光强度时增加变缓,并趋于稳定;③不同种群、生长阶段对蝗虫的波长、光强度行为反应均有一定影响,东亚飞蝗比亚洲小车蝗有更强的趋光反应率和光强可适应性,成虫比虫蝻的趋光反应率和光强适应性高。结论:光电诱导作用下,蝗虫具有明显的光谱选择行为和光强度行为反应。
OBJECTIVE: To study the phototrophic and darkening behavior of adults and insects of locusts under different color and white light stimuli, and to provide a theoretical basis for the photoelectric induced treatment of locusts. Methods: The locusts were placed in a behavioral response chamber, and behavioral test methods were used to observe and select the wavelength selective responses of locusts and their moving speed under different light intensities. Results: ① The locusts had the opposite wavelength selection mechanism of phototaxis and darkening response. Their phototaxis was strong in the short wavelength bands such as violet, blue and green, but weak in long wavelength bands such as red and orange light. ② Low light intensity Range, the locusts photophoretic reaction rate increases with the increase of light intensity, to a certain light intensity increases slowly, and tends to be stable; ③ different populations, growth stages of the locusts wavelength, light intensity behavior response has a certain As a result, the oriental migratory locusts have stronger photophoretic response and light adaptability than the locusts of Asian locusts. Adult adults have higher phototactic response rate and light intensity than that of insects. Conclusion: Under the action of photoelectric induction, locusts have obvious spectral selection behavior and light intensity behavior response.
