摘　　要：利用自制的昆虫趋光行为测试装置测定柑橘木虱和柚喀木虱成虫对自然光和10种不同波长单色光(波长340~689 nm)的趋光反应,比较两者的趋光差异性.结果表明,柑橘木虱和柚喀木虱对自然光(白光)和10种不同波长单色光均具有正趋光性.在所有测试光谱中,柑橘木虱对380 nm的紫外光的趋光率最高(83%),其次是549 nm的黄绿光(70%)和414 nm的紫光(63%);柚喀木虱对340 nm的紫外光的趋光率最高(60%),其次是对白光(47%)和50 nm的蓝绿光(30%).整体来看,柑橘木虱对10种单色光的平均趋光率(49%)显著高于柚喀木虱(13%).To compare the difference in their phototactic characteristics, the phototactic reactions of Diaphorina citri and Cacopsylla citrisuga(Hemiptera: Psyllidae) were measured with a self-made device for testing insects’ phototactic behavior. The results indicate that both of adult D.citri and C. citrisuga showed positive phototaxis to the whole-spectrum lights and 10 kinds of different monochromatic light. Among all the testing lights, UV light(380 nm) elicited the strongest phototactic rate(83%) from D. citri, followed by 549 nm(70%) and 414 nm(63%). UV light(340 nm) elicited the strongest phototactic rate(60%) from C.citrisuga, followed by whole-spectrum lights(47%) and 504 nm(30%). Overall, the average phototactic rate(49%) of D. citri to 10 kinds of different monochromatic light significantly exceeded the C. citrisuga(13%).
