Abstract

Apple snail is one of the 100 invasive alien species of the world and saponin proved to be the most effective and promising bioactive compound to manage this pest. This study was conducted to develop a saponin based wettable powder formulation from Phaleria macrocarpa (Scheff.) Borel and to evaluate its efficacy against Pomacea maculata Perry undrer laboratory and glasshouse conditions. Results revealed that all prepared saponin based wettable formulations shown molluscicide effects towards P. maculata. However, F4 formulation consisted of Terwet® 157, Terspers® 2700 and Kaolin at proportion of 15:15:70 revealed significantly higher feeding deterrent activities among prepared formulations and it was not significantly different from positive controls niclosamide and tea seed cake. In terms of lethel effects, the shortest LT50 (154 minutes) was recorded in niclosamide followed by 702 minutes in F4 formulation and 728 minutes in tea seed cake. F4 formulation along with positive control tea seed cake was further assessed in glasshouse condition. F4 formulation illustrated shortest LT50 value (750 minutes) with lowest feeding consumption percentage (0.6%) compared to LT50 (784 minutes) and feeding consumption percentage (1.3%) in positive control tea seed cake. Feeding consumption percentage (40.6%) was recorded for negative control water. Results sugest that F4 saponin based wettable powder overall performed better and can be efficiently used to control the apple snails as an eco friendly botanical molluscicide.
