Occurrence and biology of Dinocampus coccinellae (Schrank, 1802) (Hymenoptera; Braconidae: Euphorinae) parasitising different species of Coccinellidae (Coleoptera) in Neotropical region

surveys on coccinellidae (coleoptera) in sete lagoas city, minas gerais state, brazil, indicated the parasitism of adults of the species coleomegilla maculata de geer, 1775, eriopis connexa (germar, 1824) and olla v-nigrum (mulsant, 1866), by dinocampus coccinellae (schrank, 1802) (hymenoptera; braconidae: euphorinae). since then, the parasitoid have been maintained in its original hosts at the insect rearing laboratory - lacri of the brazilian agricultural research institution - embrapa milho e sorgo. besides the citation of occurrence in brazil, this work also indicates the parasitoid preference for c. maculata (70% of parasitism), followed by o. v-nigrum (43.3% of parasitism) and e. connexa (36.7% of parasitism). total life cycle of d. coccinellae was longer on c. maculata (32.4 ± 0.48 days), compared to o. v-nigrum (29.5 ± 0.49 days) and e. connexa (27.8 ± 0.4 days). due to the relatively high percentage of field parasitism, d. coccinellae can reduce the efficiency of biological pest control by coccinellidae predators especially in the case of c. maculata.
