摘要
测定福寿螺Ampullarium crosseana Hidalgo(Pomacea canaliculata Lamarck)的适温范围为8～38℃,低于0℃或高于40℃就会被冻死或灼死。通过田间条件下螺饲养试验,用牛顿-马夸法拟合有效积温方程,确定螺的发育零点和有效积温分别为11.419 9℃、1 309.225 0日度。通过恒温下卵孵化实验确定卵的发育零点和有效积温分别为14.032 1℃、94.875 2日度。全世代发育零点和有效积温分别为11.672 1℃、1 404.100 2日度。用全国670个气象站(点)30 a的气候资料预测了福寿螺的适生区和在各地的年发生代数。研究结果可作为制定检疫政策的依据。
The experimental results showed that the viable temperature and fatal temperature of ampullaria snail (Ampullarium crosseana Hidalgo/Pomacea canaliculata Lamarck) were 8 - 38 ℃ ,lower than 0℃ and higher than 40 C respectively. The experiments under natural feeding condition, fitting to Effective Accumulated Temperature (EAT) equation by nonlinear Niuto-Marquardt showed that the developmental zero and EAT of shell were 11. 4199 ℃ and 1309. 2250 day-degree respectively. Incubating test under condition of constant temperature showed the developmental zero and EAT of its egg were 14. 0321℃ and 94. 8752 day-degree respectively, and those of its whole generation were 11. 6731℃ and 1404.1002 day-degree respectively. Using 30-year climate data of 670 meteoroligical stations all over the country, the potential risk regions and generations a year of ampullaria snail in China were estimated. These results were useful and helpful in making quarantine policy.
