雌雄福寿螺取食和对异性选择行为的差异
Differences of female and male Pomacea canaliculata in foraging and heterosexual choice
摘要
Abstract
Pomacea canaliculata is an invasive alien species very harmful to the rice production in South China. In this paper, an indoor incubation test was conducted to study the differences in the foraging rate and hepatic glycogen content of female and male P. Canaliculata, and the self-designed T-maze and three-room connected device were adopted to observe the food selection and heterosexual choice of the females and males. At both hungry and full states, the females had a significantly higher foraging rate than the males. At hungry state, the females spent a shorter time for food selection but the selection frequency was not significantly different from that of the males, and also, the females spent a shorter time and had a higher frequency for food selection than at full state whereas the males didn' t show any difference. In reproductive season ( August), the females stored more hepatic glycogen in their body, but did not in non-reproductive season (November) . The males more chose the rooms with females whereas the females had less choice for males, indicating that the females were attracted by the males, while the latter had less attraction to the females.关键词
