Géneros de Braconidae del estado de Guanajuato (Insecta: Hymenoptera)

Abstract

A number of 153 collects of braconids were made from different localities of Guanajuato, México; The collecting was May 20, 1 995 to October 11, 1996. In order to complement the Information of the braconids from Guanajuato, we checked the collections of Instituto de Fitosanidad del Colegio de Postgraduados (CEIFIT), Instituto Nacional de Investigaciones Agrícolas, Forestales y Agropecuarias (INIFAP) and Escuela Superior de Agricultura del Copal, Irapuato, Gto. (LTC). A list of 61 genera in 31 tribes and 19 subfamiües of braconids from Guanajuato was obtained. The most abundant genera were Aphidius, Opius and Apanteles. The most representative (because its high number of species) genera were Bracon and Opius. The most representative subfamilies were Alysiinae and Euphorinae. From these genera, 45 are new records to Guanajuato; and one is new record to México. The new report to México is Eubazus. Species from the genera Aphidius, Diaeretiella, Lysiphlebus, Praon, Trioxys. Habrobracon, Bracon, Digonogastra, Chelonus, Meteorus, Apanteles, Cotesia, Opius, Orgilus and Aleiodes, were found to be parasitic on different pest species of economic importance. A key to genera identification from Guanajuato was translated and modified from Wharton et al(1997) with illustrations, using morpliological characters. We implemented a data base in the Paradox program, from which we made a catalogue of braconids from Guanajuato.
