This species is notorious for its detrimental impact on agricultural crops in areas where it is found, making it one of the largest and most harmful land snail pests globally. Its widespread distribution is attributed to several factors, including a high reproductive biological rate, aggressive feeding behavior, insufficient quarantine measures, and human-assisted movement. This review discusses the detrimental effects of snail infestations on agriculture, their biology and management.
