Mating behaviour, mate choice and female resistance in the bean flower thrips (Megalurothrips sjostedti)

Abstract Many species of thrips (Thysanoptera) in the family Thripidae form mating aggregations, but the adaptive significance of these aggregations and the extent of male and female mate choice is poorly understood. We studied the mating behaviour of the bean flower thrips Megalurothrips sjostedti...
