青棉花藤和杜仲藤联合对福寿螺的杀灭效果

Combination of Pileostegia viburnoides and Parabarium micranthum on the Killing Effect of Pomacea canaliculata

摘要: 为有效控制外来入侵物种福寿螺的迅速蔓延和危害，研究有效杀灭福寿螺的方法是非常必要的。本文选择中草药青棉花藤和杜仲藤提取物1:1混合进行杀灭福寿螺实验。青棉花藤和杜仲藤烘干、磨成粉末，采用索氏提取法获得混合物母液，取母液稀释后进行杀灭实验。通过室内浸杀实验(4.0 g/L，48 h，死亡率100%，P < 0.001)和野外茭白田铺撒实验(4.0 g/L，72 h，死亡率100%，P < 0.001)都能有效杀灭福寿螺，并且对茭白生长安全无影响；此外，该混合药剂能抑制福寿螺活性，有麻醉效果，能防止逃逸。综上，青棉花藤和杜仲藤混合药剂能有效抑制并杀灭福寿螺，对其他植物无影响，是快速且安全环保的植物型灭螺药剂。

Abstract: In order to effectively control the rapid spread and damage of the alien invasive species, it is nec-essary to study the effective methods of killing Pomacea canaliculata. In this article, we choose the 1:1 Chinese herbal extracts of Pileostigia viburnoides and Parabarium micranthum for the experi-ment of killing Pomacea canaliculata. Pileostigia viburnoides and Parabarium micranthum were dried, ground into powder. Soxhlet extraction was used to obtain the mother liquor of the mixture, and the mother liquor was diluted and then subjected to the killing experiment. Both indoor im-mersion test (4.0 g/L, 48 h, mortality rate 100%, P < 0.001) and field Zizania latifolia experiment (4.0 g/L, 72 h, mortality rate 100%, P < 0.001) could effectively kill Pomacea canaliculata, and had no effect on the growth safety of Zizania latifolia. In addition, the mixture can inhibit the activity of Pomacea canaliculata and prevent them escaping. In conclusion, Pileostigia viburnoides and Parabarium micranthum mixture can effectively inhibit and kill Pomacea canaliculata, without any effect on other plants growth. It is a fast, safe and environmental friendly plant molluscicide.
