The influence of commercial food grade essences on the efficacy of metaldehyde for the control of Achatina (Lissachatina) fulica (Bowdich)
The highly invasive giant African snail (GAS) has been found in several agricultural areas of Trinidad. Because this snail is able to feed on many different types of crops, it is proving to be a serious threat to the economic viability of farmers in this country. The results presented in this study...

The highly invasive giant African snail (GAS) has been found in several agricultural areas of Trinidad. Because this snail is able to feed on many different types of crops, it is proving to be a serious threat to the economic viability of farmers in this country. The results presented in this study are the most recent of several pest control strategies attempted. Five cotton pads, soaked with 1:1 mixtures (by volume) of each of five food grade essences (Aniseed, Banana, Coconut, Lemon and Vanilla) and metaldehyde, and a sixth pad of only metaldehyde (the control), were placed at strategic distances from each other in each of five blocked patterns at various sites in each of two locations, known to be infested with GAS. The number of snail deaths was recorded for each pad and the maturity stages of snails were noted.
