Abstract

Achatina sp. is a common pest that can cause severe damage to plant. This will cause losses of yield and lower the quality of plant. Synthetic molluscicides is a common method in controlling the snails. However, this will cause detrimental effects to the environment and biodiversity. Alternative method in controlling the snails are by using organic repellents such as neem, mint, coffee and garlic. The objectives of the study are to investigate the time taken for snail to response toward different organic repellent and to determine the effectiveness of organic repellent toward the juvenile and adult land snails. All the four repellents used have their effectiveness towards the repelling the snail agriculture pest were compared. Two stages of giant African snail were tested which juvenile and adult with four treatments of neem, garlic, mint and coffee respectively. Two snails were used in each replication. The parameter taken was the time taken for snails to move away from the repellents to the furthest distance in plastic container. The results shows that all four repellents, which are neem, garlic, mint and coffee are effective in repelling the snail and are correlated to the stages of the snails. The younger size of snails with took the fastest time to repel. The most effective repellent are coffee and garlic because snails take the fastest time when the concentration is 50% the repelling time is 173 seconds for adult while the repelling time is 171 seconds for juvenile. The repelling time of adult for garlic when the concentration is 50% is 227 seconds while for juvenile is 203 seconds.
