Effects of five exotic invasive plants extracts on the survival of the invasive snail Pomacea canaliculata (Lamarck).
The toxicity of cold water (25±1) and boiling water extracts of 5-invasive plants including Mikania micrantha (Kunth), Wedelia trilobata (Linnaeus), Ageratum conyzoides (Linnaeus), Ambrosia artemisiifolia (Linnaeus) and Spartina alterniflora (Loisel) was examined on mortality of golden apple snails (Pomacea canaliculata Lamarck). The cold water extracts were more toxic than boiling water extracts. The toxic potential of tested water extracts followed the order: M. micrantha > W. trilobata > A. conyzoides > A. artemisiifolia > S. alterniflora. The toxicity of water extracts varied with concentration. Among the 5-plants tested, M. micrantha proved most toxic to snails.
