The result showed a quite different phototaxis among 5 optical fields that the guppy fry displayed a high phototaxis of 99% under blue light with the illuminance of 1 500~2 000 lx while comparing with the low phototaxis under re.
结果表明,孔雀鱼幼苗对5种颜色光表现出不同程度的趋光性和选择性,对蓝光的趋光性最强,其趋光率高达99%,相应的照度范围为1 500~2 000 lx,对红光的趋光性最小。
The phototaxis on 8 species stored-product insects was detected by using device of color response for red light (750～630nm),yellow light (600～570nm),green light(570～490nm),violet light (430～380nm) and blue light (460～430nm).
采用储粮昆虫趋光性测试装置测定了红、黄、绿、紫及蓝色光对8种储粮昆虫的光趋避强度,测试结果表明,在黑暗条件下,各试虫处理分布差异都达不到5 %水平的显著水平,而红、黄、绿、紫及蓝色光处理试虫分布都存在一定的差异。
