| Resumo: |
Larvae of A. citrinopsis Dyar were found feeding on leaves of castor-bean plants (Ricinus communis L.) on plantations at Caiuá, Tupi Paulista, Junqueirópolis, Ouro Verde, Marabá Paulista and Cândido Rodrigues, in the State of São Paulo, Brazil. The larvae feed on the lower surface of leaves, were they form cocoon and pupate later on. Only at Junqueirópolis the infestation was high, but there was a natural decrease in the insect population. The hymenopterous Glyptapanteles dalosoma Santis, 1987 (Braconidae), Ceratosmicra argentina Blanchard, 1942 (Chalcididae) and Isdromas monterai (Costa Lima, 1948) (Ichneumonidae) were reared from larvae; the latter two probably behaved as hyperparasites.
