摘  要：
为探讨昆虫的趋光性和灯光诱捕技术在储粮害虫防治中的应用,在实验室条件下探究了光源波长、光强、虫龄、虫口密度和饥饿处理对谷蠹成虫趋光行为的影响。结果表明,在可见光区,谷蠹趋光性较强的波长范围在530nm和575nm,在紫外光区,谷蠹趋光性较强的波长为365、385和395nm。在一定的光强范围内,谷蠹的趋光性随光强度的增强而增大。随着日龄的增加,趋光性先增强后逐渐减弱,10~15日龄成虫的趋光性最强。随着成虫饥饿处理时间的延长,谷蠹的趋光性先增强后减弱,饥饿处理2d的趋光性最强。随着释放虫口密度的增加,谷蠹的趋光性增强。研究结果为谷蠹灯光诱捕技术的研究和应用提供了一些参考。

摘  要：
To discuss the insect phototaxis and popularize the application of light trapping technology in the integrated management of stored product pests,the effects of light wavelength,light intensity,insect age,population density and deprivation of food on the phototactic behavior of Rhyzopertha dominica(Fabricius)adults were evaluated under the laboratory conditions.The results showed that beetles showed higher phototaxis to530 and575 nm wavelengths within the visible light spectrum.Within the ultraviolet light spectrum,beetles showed higher phototaxis to the wavelengths of 365 nm,385 nm and395 nm.Within a certain range of light intensity,their phototaxis increased with the increment of light intensity.With the increment of the age,their phototaxis initially reached to aplateau at the age of 10-15 days and then shrank;with the increment of starvation period,their phototaxis initially reached to a plateau after 2 d of starvation and then shrank;with the increment of the insect density,their phototaxis increased.These data provide some references to the research and application of light trapping of R.dominica.
