摘要/Abstract

摘要： 为获得灰茶尺蠖（Ectropis grisescens Warren）的趋光/避光反应特征、光谱反应范围及性别差异,采用光行为学的方法研究了370~600 nm范围内的18种不同波长的单色光对成虫趋光、避光反应行为的影响。结果显示,各单色光均能引起灰茶尺蠖成虫一定的趋光或避光反应,雌虫在橙光（600~605 nm）、绿光（520~525 nm）、紫光（370~375 nm）范围内趋光性明显;雄虫在绿光（520~525 nm）、紫光（395~400 nm和390~395 nm）范围内趋光性明显;雌虫在冰蓝青光（490~495 nm）、蓝光（440~450 nm）和红光（660~665 nm）范围内避光性明显;雄虫在紫光（400~405 nm）、蓝光（440~450 nm）、冰蓝青光（490~495 nm）和自然白光（CK）范围内避光率较高。研究表明,灰茶尺蠖成虫对不同波长光的趋、避性存在差异,性别对其光谱行为反应有一定的影响。

Abstract: The study aims to get the sensitive spectral range of Ectropis grisescens Warren to different light spectrum. The phototaxis or photophobism behavior of E. grisescens Warren in response to spectral sensitivity was tested under 18 monochromatic lights ranging from 370 nm to 600 nm in the laboratory. The results show that phototaxis or photophobism reaction were observed under all the tested monochromatic wavelengths between 370 nm and 600 nm spectrum. The female adults showed positive phototaxis under orange light (600-605 nm), green light (520-525 nm) and ultraviolet light (370-375 nm). Meanwhile the male adults showed phototaxis under green light (520-525 nm), ultraviolet light (395-400 nm) and ultraviolet light (390-395 nm). The female adults showed photophobia under ice indigo light (490-495 nm), blue light (440-450 nm) and red light (660-665 nm). Meanwhile the male adults showed photophobia under ultraviolet light (400-405 nm), blue light (440-450 nm), ice indigo light (490-495 nm) and CK. There are differences inphototaxis of E. grisescens Warren to light at different wavelengths, and gender is an important factor affecting the spectral behavior response. This study not only provided a necessary theoretical foundation for further research on light vision of E. grisescens Warren, but also provided a scientific basis for the use of phototaxis in the integrated management of E. grisescens Warren.
