ABSTRACT
The structure and composition of the assemblage of pupal parasitoids of Phyllocnistis citrella Stainton, the citrus leafminer, were studied in two citrus orchards (Citrus deliciosa Tenore cv. Montenegrina and Citrus sinensis (L.) Osbeck x Citrus reticulata Blanco hybrid Murcott), in Montenegro County (29° 68’S and 51° 46’W), southern Brazil. At fortnightly samplings, from July 2001 to June 2003, all the new shoots from 24 randomly selected trees were inspected. The species richness reached five native species in the Murcott orchard, and six in Montenegrina. In Murcott, the presence of Ageniaspis citricola (Hymenoptera Encyrtidae), an exotic species, was detected in the first year of sampling, probably migrating from the nearby areas where it had been released for the miner control. In Montenegrina, its presence was only registered in the second year. A. citricola in both areas was dominant and changed the community structure of parasitoid complex of P. citrella in both orchards.
RESUMO
A estrutura e a composição da assembléia de parasitóides que emergiam na fase de pupa de Phyllocnistis citrella Stainton, o minador-dos-citros, foram estudadas em dois pomares de citros (Citrus deliciosa Tenore cv. Montenegrina e Citrus sinensis (L.) Osbeck x Citrus reticulata Blanco híbrido Murcott), no Município de Montenegro (29° 68’S, 51° 46’O), RS. Em 49 ocasiões de amostragem de jul/2001 a jun/2003, todos os brotos de 24 árvores escolhidas aleatoriamente foram inspecionados. Foram registradas cinco espécies de parasitóides nativos no pomar de Murcott e seis em Montenegrina. Em Murcott, a presença de Ageniaspis citricola Logvinovskaya (Hymenoptera Encyrtidae), espécie exótica, foi detectada no primeiro ano de amostragem, provavelmente migrando de áreas adjacentes ao pomar onde foi liberada para o controle do minador. Em Montenegrina, sua presença foi registrada somente no segundo ano. A. citricola foi a espécie dominante em ambas as áreas e provocou mudanças na estrutura do complexo de parasitóides de P. citrella nos dois pomares.
