Abstract
Orius insidiosus (Say) was observed to successfully prey on eggs and earlier instar larvae of the fall armyworm (FAW),Spodoptera frugiperda (J. E. Smith). Significantly more neonates of FAW were killed per 24 h than either 1, 2 or 3 d old larvae. Female and male predators exhibited a typical type-II functional response when preying on varying densities of eggs or neonates of FAW.
Résumé
On a observé que les adultes d'O. insidiosus mangeaient les œufs et les stades les plus jeunes de la chenille «légionnaire»Spodoptera frugiperda (J. E. Smith). Il y avait significativement plus de larves néonates tuées en 24 h que de larves âgées de 1, 2 ou 3 jours. Les prédateurs mâles et femelles ont montré une réponse fonctionnelle de type II lorsqu'ils se nourrissaient sur des densités variées d'œufs et de larves néonates de la chenille «légionnaire».
