福寿螺对不同颜色光的趋避效应初探

The Preliminary Study on Phototaxis and Apheliotropism of Ampullaria gigas to Different Clolor Lights

采用不同颜色(即不同波长)的光对福寿螺(Ampullaria gigas)进行室内照射试验,分析探讨了不同壳色福寿螺的趋避效应。结果发现,黄壳螺较黑壳螺对光更为敏感,橙色和红色光对黄螺有明显的驱避效应,黄螺对黄色光趋向性最高;红色光对黑螺有明显的驱避效应,黑螺对绿光和蓝光的趋向效应更为明显。研究结果可为利用灯光对稻田福寿螺进行物理防控提供一定的科学依据。

A laboratory experiment was conducted to investigate the effect of different color lights on two varieties of golden apple snails （Ampullaria gigas） which were distinguished in yellow and black shell color, aimed to explore their different phototonus to lights. The result showed that yellow snails were more sensitive to light than black ones. Both yellow and black snails had a significant phototaxis or apheliotropism differences under certain light colors. This research would be of vital importance for physical control of apple snails by using particular lights in paddy field.
