This article describes how the abundance of the banana weevil, Cosmopolites sordidus, and the abundance of the earwig Euborellia caraibea were affected by the addition of a cover crop. The data presented in this article are related to the research article entitled “Cover cropping reduces the abundance of the banana weevil Cosmopolites sordidus but does not reduce its damage to the banana plants†(Carval et al., in press).

Live females, collected volatiles from females and female hindguts, elicited small or no behavioral responses from either sex. Male weevils were attracted to volatiles trapped from males and made longer visits to live males and volatiles from males. Evidence for volatile male-produced pheromone in banana weevilCosmopolites sordidus.įemales of the banana weevil,Cosmopolites sordidus, were attracted to and made longer visits to live conspecific males, trapped volatiles from males, and dissected male hindguts in a still-air olfactometer. ![]()
