摘　　要：目的描述我国广州地区福寿螺的形态差异,期望为广州管圆线虫病防治的研究及福寿螺蔓延控制的研究提供证据。方法对广州地区黑色福寿螺、黄色福寿螺、灰色福寿螺的螺壳、软体部、呼吸管、足、齿舌进行观察,描述三类福寿螺的形态学差异。结果对三类福寿螺的足及呼吸管进行HE染色分析,显示软体部颜色不同的原因主要是黑色颗粒的有无和沉积数量的多少。对福寿螺齿舌的观察显示,灰色福寿螺第一、第二突起与中央齿宽的比值明显大于黑色福寿螺和黄色福寿螺;在扫描电镜下,三类福寿螺的齿舌未见明显不同。结论我国广州地区的福寿螺存在三种变异。Based on the characteristics of Pomacea canaliculata＇s external shell and its soft part,they were divided into 3 types： black P.canaliculata,yellow P.canaliculata,and grey P.canaliculata.HE staining of their breathing tubes and feet proved that the different colors of the soft parts mainly resulted from the existence of melanin granules and the number of deposition.During the observation of the radula of P.canaliculata,the ratios of the first and second cusp to the centre radula of grey P.canaliculata largely exceeded that of the black and grey P.canaliculata.The differences of the three types were difficult to judge under scanning electron microscope.It＇s suggested that the analysis of the above differences of P.canaliculata would provide evidence in the researches about the treatment of angiostrongyliasis and the control of spread of P.canaliculata.
