Abstract

The present study was conducted in traditional coffee agroecosystems within the buffer zone of the Los Tuxtlas Biosphere Reserve, Veracruz. The main objectives were to identify the beetles associated with this type of agroecosystems, and describe their general structure in order to know the main characteristics that provide refuge to these organisms. Two traditional coffee agroecosystems were selected, the first located at 600 m.a.s.l (meters above sea level) and the second at 900 m.a.s.l; the number of strata was visually determined. The beetles were collected every 15 days with the help of an insect net, strata by strata, within a 1000 m2 transect. Three hundred and eighty specimens, representing 18 families, 24 subfamilies, 17 tribes and 52 genera were collected. In Site One the most abundant families were Chrysomelidae (45%) and Passalidae (13.4%); while in Site Two were Chrysomelidae (21.2%) and Passalidae (20.4%). The most abundant genera and species in Site One were Lemma diversa (13.4%), Oulema melanopus (12%) and Passalus punctatostriatus (9.9%); in Site Two Passalus punctatostriatus (15%) and different Lemma species (12%). Azya luteipes is an important component of both sites. It is the first time species from Pseudoccocidae are reported for Mexico, Azya luteipes was originally reported for Central and South America where is frequently used as a general biological control beetle.

Keywords: Agro-ecological matrix, structure, Azya luteipes, Mexico.
