The coccinellids Eriopis connexa (Germar), Harmonia axyridis (Pallas) and Olla v-nigrum (Mulsant) are important natural biological control agents. The purpose of this paper was to study the biology and create a fertility life table of these three coccinellid species. For the biology study, 50 insects/species were used and kept in groups of 10 in glass vials (2300cm3). For the three species studied, the viability of the total cycle varied from 45 to 50%. O. v-nigrum was the species which presented the longest oviposition period. However, H. axiridis demonstrated the best reproductive performance and ability of population growth in each generation. In conclusion, the use of commercially obtained pollen and A. kuenhiella eggs enables the development of coccinellids E. connexa, H. axyridis and O. v-nigrum under laboratory conditions, since the insects completed their biological cycle and originated adults with good reproductive performance.

Os coccinelídeos Eriopis connexa (Germar), Harmonia axyridis (Pallas) e Olla v-nigrum (Mulsant) são importantes agentes de controle biológico natural. O objetivo deste trabalho foi estudar a biologia e a tabela de vida de fertilidade dessas três espécies de coccinelídeos. Para a biologia foram utilizados 50 insetos/espécie, mantidos em grupo de 10 em recipientes de vidro de (2300cm3). Para as três espécies estudadas, a viabilidade do ciclo total variou de 45 a 50%. O. v-nigrum foi a espécie que apresentou maior período de oviposição. No entanto, H. axiridis foi àquela que demonstrou maior performance reprodutiva e capacidade de aumento populacional a cada geração. Em conclusão, a utilização de pólen comercial e ovos de A. kuenhiella possibilita o desenvolvimento dos coccinelídeos E. connexa, H. axyridis e O. v-nigrum em condições de laboratório, pois, os insetos completaram o ciclo biológico e originaram adultos com boa performance reprodutiva.
