Abstract in Portuguese
Esta pesquisa foi executada com o objetivo de estudar a morfologia e alguns aspectos biológicos de Olla v­nigrum (Mulsant, 1866) e Cycloneda conjugata Mulsant, 1866 (Coleoptera, Coccinellidae), predadores de Psylla sp. (Homoptera, Psyllidae) que ataca a sibipiruna, Caesalpinia pelthophoroides Benth. Foram caracterizadas através de desenhos, as fases de ovo, larva, pupa e adulto de cada espécie de Coccinellidae. Foi observado que Psylla sp. vive em simbiose com Pheidole sp. e Brachymyrmex sp. (Hymenoptera, Formicidae). Os pulgões da colza (Brassica napus Metzg.) podem ser predados por O. v-nigrum. Homalotylus sp. (Hymenoptera, Encyrtidae) parasita as larvas de e C. conjugata. Os adultos de C. conjugata passam o inverno em estado de dormência, em folhas enroladas.

Morphology and biological aspects of Olla v-nigrum (Mulsant, 1866) and Cycloneda conjugata Mulsant, 1866 (Col., Coccinellidae) predators of Psylla sp. (Homoptera, Psyllidae) on sibipiruna (Caesalpinia pelthophoroides Benth.)
Abstract in English
This research deals with the study of the morphology and some biological aspects of Olla v-nigrum (Mulsant, 1866) and Cycloneda conjugata Mulsant, 1866 (Coleoptera, Coccinellidae) predators of Psylla sp. (Homoptera, Psyllidae) a pest on sibipiruna (Caesalpinia pelthophoroides Benth.). Descriptions and illustrations of the stages of egg, larva, pupa and adult are provided. Psylla sp. presents a symbiosis with Pheidole sp. and Brachymyrmex sp. (Hymenoptera, Formicidae). O. v-nigrum was observed preying aphids on colza (Brassica napus Metzg). Homalotylus sp. (Hymenoptera, Encyrtidae) is a larval parasite of C. conjugata. The adults of C. conjugata overwinter in dormancy among rolled plant leaves.
