Sexual dimorphism in the 1st instar of the cochineal insect dactylopius austrinus homoptera dactylopiidae



Sexual dimorphism in the 1st instar of the cochineal insect dactylopius austrinus homoptera dactylopiidae



Journal of the Entomological Society of Southern Africa 41(2): 333-338



A simple and reliable method that allows separation of the sexes in the 1st instar of D. austrinus is reported. This is the 1st time that clear sexual dimorphism has been noted in the crawlers of the Dactylopiidae. The crawlers, after emergence, develop long filaments on the dorsal surface of the body. The pattern, number and growth rate of the filaments differs in males and females and these differences allow the living crawlers to be sexed.
