MELO, Thiago Lima et al. Parasitoid communities of Leucoptera coffeella (Guérin-Mèneville & Perrottet, 1842) (Lepidoptera: Lyonetiidae) in coffee plants in the western and southwestern regions of Bahia state, Brazil. Ciênc. agrotec. [online]. 2007, vol.31, n.4, pp.966-972. ISSN 1413-7054.

The aim of this work was to know the diversity and the structure of parasitoid communities of Leucoptera coffeella (Guérin-Mèneville & Perrottet, 1842) in the West, municipality of Luiz Eduardo Magalhães, and in the Southwest, municipality of Vitória da Conquista, of the State of Bahia, Brazil. The studies were developed in 2002 and 2003, by monthly samplings of leaves from the fourth pair, of branches in the three plant strata and those fallen on the ground, with a total of 1600 leaves per region and sampling period, and by collecting mines containing pupae of parasitoids and chrysalis. The material was kept in the Entomology Laboratory of the State University of Southwestern Bahia (Universidade Estadual do Sudoeste da Bahia - UESB), under ambient temperature, for the emergency of adults. The structure of communities was assessed by means of the faunistic indexes, frequency, constancy, dominance and diversity. Six parasitoid species belonging to Braconidade and Eulophidae were identified, namely parasitoids Cirrospilus neotropicus (Diez & Fidalgo, 2003); Closteroscerus coffeellae (Ihering, 1914); Horismenus aeneicollis (Ashmead, 1904); Neochrysocharis coffeae (Ihering, 1914); Stiropius sp.1 and Stiropius sp.2 associated to plant coffee leaf miner. There are differences in the structure of parasitoid communities according to the studied regions, being given that in the Western Region the predominant species was N. coffeae, while in the Southwestern Region, H. aeneicollis and Stiropius sp.1 were the predominant ones.
