利用LED光源、温控加热装置和行为反应试验装置,采用对比试验法进行蝗虫趋光增益性热源温度的优选,探讨光温耦合效应与环境温度作用对蝗虫趋光增益行为影响的机理。结果显示:热源温度、光谱色光照、环境温度及蝗虫昼行夜伏性活动规律影响夜间蝗虫对光温耦合效应的选择,热源温度于蝗虫的趋光响应具有增益效应,其中以65℃热源温度于蝗虫的趋光增益作用最佳;同一时间段内,蝗虫对紫光与65℃热源温度耦合效应的选择最优;热源温度对蝗虫的光温诱导起增益群集作用,光谱色光照对蝗虫诱导起主要作用。
By using LED light source, temperature control heating device and behavior reaction test device, the comparative experiment method was used to optimize the temperature of the locust’s phototropism gain heat source, and the mechanism of light-temperature coupling effect and ambient temperature on locust phototropism gain behavior was discussed. The results showed that the heat source temperature, spectral color illumination, ambient temperature and day-night activity of locusts influenced the night-time locusts’ selection of light-temperature coupling effect. The heat source temperature had a gain effect on the locust phototrophic response. For locusts, the phototrophic gain was the best. During the same time period, locusts had the best choice of the coupling effect between temperature and UV light source temperature of 65 ℃. The heat source temperature induced the cluster effect of locust light and temperature, main effect.
