摘　　要：【目的】研究光照强度对稻水象甲飞行能力的影响,探索稻水象甲的迁飞规律,为控制稻水象甲的扩散提供依据。【方法】通过昆虫飞行磨系统测定不同光照强度下稻水象甲的飞行能力。【结果】稻水象甲在光照强度为100 lx时飞行能力最强,且其飞行能力随着光照强度的增加而下降。【结论】光照强度对稻水象甲的飞行能力影响较大,弱光照强度下,稻水象甲容易迁飞,100 lx是稻水象甲的最适飞行光照强度。在相同光照强度等条件下,稻水象甲越冬后成虫和入土前的飞行能力无明显差别。[ Objective ] The flight capacity of the rice water weevil：Lissorbqptrus oryzqphilus kuschel （LOK） in different light intensities was studied, and the flight law of the LOK was explored in order to provide evidence for preventing LOK from dispersal. [ Method] Systematic study was conducted about the LOK＇s flight capacity under the different light intensities by using the computer - monitored flight - mill. [ Result] When the light intensity was 100lx,the flight capacity of the LOK was the strongest, and the flight capacity decreased with the rise of light intensity. [ Conclusion ] Light intensity had greater effect on flight capacity, under the weak light intensity, the LOK can migrate easily, and the optimum flight light intensity was 100 Ix. In the same light intensity conditions, there was no obvious difference between overwintering LOK and before earthed LOK on the flight capacity.
