摘要: 将蜗牛身体倒置并记录其恢复原状的时间来研究灰尖巴蜗牛的翻身习性,并研究蜗牛体重、环境温度、光照强度、饥饿和取食等因素对翻身时间的影响。结果表明,翻身时间随体重、光照强度和饥饿时间增加而增加,随温度升高和取食时间增加而减少。体重组Ⅳ(体重0.7~0.9 g)、Ⅴ(体重0.9~1.2 g)的翻身时间极显著长于体重组Ⅰ(体重0.1~0.3 g)、Ⅱ(体重0.3~0.5g)、Ⅲ(体重0.5~0.7 g)(P<0.01),体重组Ⅰ的翻身时间显著短于体重组Ⅲ的(P<0.05);3体重组(Ⅰ、Ⅲ、Ⅴ)在较高温度和低白炽灯光照强度(204 lx)下的翻身时间显著短于较低温度和强白炽灯光照强度(493 lx)下的;体重组Ⅰ、Ⅴ在长饥饿时间下的翻身时间均显著长于短饥饿时间。体重组Ⅲ、Ⅴ取食较长时间后的翻身时间都显著短于取食较短时间。

Abstract: In this study, the body-turning behaviors of Bradybaena ravida ravida were studied by recording the duration of the snails resuming their original posture after being put upside down. The effects of the factors such as snail body weight, environmental temperature, illumination intensity, and the time of feeding and starvation on the body-turning duration were also studied. The bodyturning duration increased with the increase of snail body weight, illumination intensity, and starvation time, but decreased with the increase of environmental temperature and feeding time. The durations of the bodyturning of groups Ⅳ and Ⅴ (snail body weight was 0.7-0.9 g and 0.9-1.2 g, respectively) were significantly longer than those of groups Ⅰ, Ⅱ, and Ⅲ (snail body weight was 0.1-0.3 g, 0.3-0.5 g and 0.5-0.7 g, respectively) (P<0.01), and the duration of body-turning of groupⅠ was significantly shorter than that of group Ⅲ (P<0.05). At higher temperature and weaker illumination intensity from electric incandescent lamp (204 lx), the body-turning durations of groups Ⅰ, Ⅲ, and Ⅴwere significantly shorter than those at lower temperature and stronger illumination intensity (493 lx). The body-turning durations of groups Ⅰ and Ⅴ that starved for longer time were significantly longer than those starved for shorter time. When fed for longer time, the body-turning durations of groups Ⅲ and Ⅴ were significantly shorter than those fed for shorter time.
