中文摘要：测定了白背飞虱及其天敌黑肩绿盲蝽对紫光（410nm - 415nm）、蓝光（455 nm - 458 nm）、绿光（515 nm - 518 nm）、黄光（587 nm - 590 nm）、红光（615 nm - 618 nm）、白光（6000 k – 6500 k）等六种LED的趋光率。白背飞虱对蓝光和绿光较为敏感，且光波对白背飞虱趋光率的影响效应与暗适应时间有明显的互作；光照强度、羽化日龄及暗适应时间对白背飞虱的趋光率无显著影响。在不同光照强度下，黑肩绿盲蝽对蓝光的趋光率达（19.25±1.12）%，显著地高于其它5种光波。
英文摘要：Phototaxis of Sogatella furcifera and its natural enemy Cyrtorhinus lividipennis to 6 wavelengths of light-emitting dioded (LED) were evaluated under laboratory conditions. The results indicate that blue (455 nm - 458 nm) and green (515 nm-518 nm) LED lights were more attractive to S. furcifera. Although obvious interactions between wavelength and light intensity, days afteremergence or dark adapted time were found, none of these factors had a significant effect on phototaxis in S. furcifera, C. lividipennis was significantly attracted by blue (455 nm - 458 nm) LED lights.
