AMADO, SAVIO; GULIAS-GOMES, CLAUDIA C.  e  MILWARD-DE-AZEVEDO, ELIANE M.V.. Longevity of Musca domestica L. (Diptera: Muscidae) parasitized by Habronema muscae Carter (Nematoda: Habronematidae). Parasitol. día [online]. 2000, vol.24, n.1-2, pp.35-39. ISSN 0716-0720.  http://dx.doi.org/10.4067/S0716-07202000000100005.

The present work had as objective to evidence the influence of the parasite Habronema muscae on the Musca domestica longevity. Muscids larvae belonging to second generation, with aproximately 30 h old, were submitted to infection in artificial diet, in which were inoculated H. muscae eggs, obtained from maceration of female helminths. The muscid larvae and pupae were mantained in artificial chamber at 27o C, 60 ± 10% RH and 14 h of photophase. After emergence, the adults were distributed in screen cages, The number of dead muscids were conferred daily, with posterior dissection and ratification of infective nematode larvae. The mean intensity of infection was 3.11 infective larvae per muscid (range: 0-14) in the infected group. The infected group showed a significative reduction on mean longevity, when compared with the control (25.0 and 32.5 days, respectively). There was no difference between mean longevity from male and female dipterous.
