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.

In April 1982, at Urânia, State of São Paulo, Brazil, a high infestation of larvae of Diabrotica speciosa (Germar, 1824) (Coleoptera: Chrysomelidae) damaging roots, gynophores and pods of an irrigated peanut crop was observed. The roots, radicles and gynophores showed lesions due to the attack of the larvae; sometimes these plant parts were completely destroyed. The pods presented holes through which the larvae penetrated in order to eat the seeds. Because of the high infestation and the heavy damage the harvest of the crop was considered not economical.
