Popis: Beauveria bassiana (Bals.-Criv.) Vuill. and Metarhizium anisopliae (Metchnikoff) Sorokin were autodisseminated in the house fly, Musca domestica L., when one, five, and 10 virgin, 3-day old males exposed to 6 × 108 conidia ml-1 per fungus were confined with 30 females of the same age. Fungal treatments with one or five males killed few, with LT50 of 7 and 5 days, respectively, but when 10 funguscontaminated males were placed with 30 flies, LT50 was 3 days with a sporulation rate of 94% and 66% less oviposition. Moreover, confinement of one, five, or 10 fungal-infected males caused an incremental increase in virulence, reducing the LT50. The regression of the mean of eggs, first-instar larvae, and days of gonotrophic cycle on the LT50 values of nine treatments (six fungal groups and three checks) showed that the three variables decreased about 3–4 units per unit of LT50. Likewise, when the gonotrophic cycle time was regressed on mean oviposition, a linear equation demonstrated that for each decre...
