Estudo comparado do desenvolvimento pós-embrionário de Musca domestica Linnaeus, 1758 criada em fezes de animais domésticos sobre condições de laboratório

Abstract

The objective of the present study was to compare the development and viability of larvae, pupae and adult stages of Musca domestica L. 1758 (Díptera, Muscidae), raised in faeces of domesticated animals (cattle, swine, poultry and equines), in differents periods post-emission. The study was conducted at the laboratory of Insect Biology of the Experimental Station for Parasitological Research W.O. Neitz, Department of Animal Biology, Universidade Federal Rural do Rio de Janeiro. Faeces of Bos taurus L., Sus scrofa L., Gallus gallus L. and Equus caballus L., recently eliminated, 24, 48, 72 and 96 hours old were seeded with up to 24 hours old larvae. In horse faeces, the M. domestica larvae stages developed only in recently eliminated faeces. About treatments with bovine, swine and poultry faeces, the larval stage viability, pupae weight, duration and viability of larval to adult stage, were influenciated by the interaction factors analised (types of faeces x post-emission periods). Faeces of swine up to 72 hours old xx. and recently eliminated faeces of poultry were considered the most appropriate medium for development of M. domestica. The pupation period and viability of pupae were not influenced by type of faeces. However, the average weight of pupae of M. domestica from cattle faeces was lower than the average weight of pupae recovered from swine and poultry faeces.
