摘要： 福寿螺为100种恶性外来入侵物种之一,然而目前缺乏有效杀灭其卵块的方法。本研究利用不同浓度的氯化钙溶液对福寿螺的卵块进行杀灭。室内研究结果显示:随着氯化钙溶液浓度的升高,福寿螺卵块死亡率增加(Y=6.547 6X+6.785 7,df=8,r=0.958,p<0.001),在氯化钙浓度达到12 g/L时,卵块的死亡率可达90%;在施药后的不同时间段,用清水对施药后的卵块冲洗1 min,结果发现冲洗组的死亡率与未冲洗的空白对照组的死亡率无显著差异。室外实验结果显示,随着氯化钙溶液浓度的升高,福寿螺卵块死亡率增加(Y=1.523 8X+26.763,df=6,r=0.931 9, p<0.001),在氯化钙浓度达到40 g/L时,卵块的死亡率达到(93.33±2.89)%。以上结果表明,即使是在雨天条件下,氯化钙溶液也可有效杀灭福寿螺卵块,说明可通过对福寿螺卵块喷洒氯化钙溶液来有效杀灭福寿螺卵块。

Abstract: Pomacea canaliculata is one of the 100 most harmful invasive species in the world. However, efficient methods of killing the egg mass are not available up to now. In this study, different concentration of calcium chloride solution were used to kill the egg mass of P. canaliculata. The experiment results in laboratory showed that the death rate of the egg mass increased with the increasing of concentration of calcium chloride solution (Y=6.547 6X+6.785 7,df=8,r=0.958,p<0.001). When the calcium chloride solution concentrations reached 12 g/L, the egg mass death rate was up to 90%. In different times after applying calcium chloride solution, the egg mass were flushed by fresh water for 1 minute. The results showed that there was no significant difference between the flushing group and the no-flushing group. The results of the field experiments showed that the death rate of the egg mass increased with the increasing of concentration of calcium chloride solution too (Y= 1.523 8X+26.763, df=6, r=0.931 9, p<0.001). When the calcium chloride solution concentrations reached 40 g/L, the egg mass death rate was up to (93.33±2.89)%. All the results indicate that the calcium chloride solution can kill egg mass of P. canaliculata effectively, even in the rainy day. So, calcium chloride solution can be used to kill the egg mass of P. canaliculata.

Key words: calcium chloride, Pomacea canaliculata, egg mass, killing action
