COTESIA FLAVIPES PDF

Summary. Releases of the parasitoid Cotesia flavipes have been carried out since late in Colombia’s Cauca River Valley to complement other biological . Cotesia is a genus of Braconid wasps. Some species parasitize caterpillars of species considered as pests. Thus they are used as biocontrol agents. Cotesia. (Lepidoptera: Crambidae), used in producing the parasitoid, Cotesia flavipes Cameron (Hymenoptera: Braconidae), is representative of the problems faced by .
