摘　　要：目的掌握上海市浦东新区福寿螺孳生情况,为福寿螺的防控提供科学依据。方法采用自然行走法对福寿螺监测点进行环境监测,采集的福寿螺及卵样本进行实验室检测。采用肺检法初筛,组织匀浆法复检检测福寿螺广州管圆线虫。通过调查问卷收集居民对福寿螺信息知晓情况。采用卡方检验分析问卷调查结果。结果2023年上海市浦东新区共有111个监测点,福寿螺生存环境类型多为河流(72.97%)。本研究共检测48个螺样本,雌性33个(68.75%),平均螺长(4.83±1.39)cm,雄性15个(31.25%),平均螺长(4.69±0.83)cm;共检测56个卵样本,平均卵块长(3.72±1.16)cm,平均卵粒数(252.59±95.53)粒。实验室检测48个螺样本检测均未发现广州管圆线虫。收集有效问卷430份,其中26.74%的居民无法辨别福寿螺,31.86%的居民无法辨别福寿螺卵,41.16%的居民不清楚福寿螺及卵是否会传播疾病。不同性别(χ^(2)=8.879,P<0.05)、不同文化程度(χ^(2)=8.207,P<0.05)福寿螺信息知晓率差异有统计学意义。结论上海市浦东新区暂未发现感染广州管圆线虫的福寿螺,但福寿螺孳生较严重,居民有捕食螺行为且对福寿螺知晓率较低。因此,需做好查螺灭螺工作,并加强居民宣传。Objective To understand the breeding situation of Pomacea canaliculate in Pudong New Area,Shanghai,so as to provide scientific basis for the prevention and control of P.canaliculate.Methods Environmental monitoring of P.canaliculate monitoring sites was conducted by adopting the natural walking method.Samples and eggs were collected for laboratory testing.Preliminary screening was carried out by using lung-microscopy and tissue homogenization for reexamination in detecting Angiostrongylus cantonensis in the P.canaliculate.The residents'awareness of information about P.canaliculate was collected through a survey questionnaire.The Chi-square test was used to analyze the questionnaire results.Results In 2023,there were a total of 111 monitoring sites in Pudong New Area,Shanghai.The type of living environment of P.canaliculate was mostly rivers(72.97%).A total of 48 P.canaliculate samples were tested in this study.There were 33 females(68.75%)with an average length of(4.83±1.39)cm.There were 15 males(31.25%)with an average length of(4.69±0.83)cm.56 egg samples from P.canaliculate were tested.The average length of the egg mass was(3.72±1.16)cm,and the average number of single egg grains was(252.59±95.53)eggs.The laboratory test showed that no A.cantonensis was found in the 48 P.canaliculate samples tested.Altogether,430 valid questionnaires were collected.26.74%residents were unable to distinguish P.canaliculate,31.86% couldn't distinguish P.canaliculate eggs,and 41.16% residents were unsure whether P.canaliculate and eggs can transmit diseases.Chi-square test showed that there were significant differences in the awareness rate of information on P.canaliculate of different gender(χ^(2)=8.879,P<0.05)and different cultural levels(χ^(2)=8.207,P<0.05).Conclusion No P.canaliculate infected with A.cantonensis has been found in Pudong New Area,Shanghai.However,the proliferation of P.canaliculate is relatively serious.Residents have the act of catching and eating P.canaliculate,and have a low knowledge of P.canaliculate
