MONTILLA-CORONADO, Rafael Paúl. Pupal parasitoids of flies (Diptera) associated to the bovine cattle manure, in Aragua, Venezuela. J. Selva Andina Biosph. [online]. 2017, vol.5, n.2, pp.124-132. ISSN 2308-3859.

In livestock farms, flies are one of the main health problems, due to the diseases they transmit and the stress they cause on animals, with the consequent economic losses. In order to obtain information on the species of flies present and associated pupal parasitoids in a system of milk production of cattle from a locality of Aragua state, pupae of flies were collected in the manures found in the paddocks, and In the piles that are made when cleaning the milking rooms, The same ones were put in breeding in the insect of the Institute of Agricultural Zoology of FAGRO-UCV, in Maracay, Aragua state. The emerged adults were preserved in vials with 70% alcohol until their assembly and identification. The flies that emerged from the pastures were determined as Themira sp., (Sepsidae), Fannia sp., (Muscidae), and Musca sp., (Muscidae), manure stacks such as Musca domestica (Muscidae), Leptocera sp., (Sphaeroceridae) and Physiphora sp., (Ulidiidae). Among the parasitoids that emerged from the pupae of flies were Spalangia imitator and Spalangia cameroni (Pteromalidae), Trichopria sp., (Diapriidae) and Kleidotoma sp., (Figitidae). The degree of parasitoidism was quite low (<5%). All these records are new contributions to livestock production systems in the country, that with proper research, which can be used for the development of strategies for control of problem flies and for the industries of massification of biological controllers of such pests.
