| Popis: | Dose-mortality studies were conducted with 2 members of theEntomophthora muscae (Cohn) Fresenius complex from southern California (CA) and Denmark (DA) infecting house flies,Musca domestica L., from southern California. Primary conidia of the DA form were significantly more infective (LC50=34 conidia/mm2) than primary conidia of the CA form (LC50=67 conidia/mm2) for 2–7 days old (‘young’) flies. Infectivity (single experimental trial) for 10–14 day old (‘old’) flies of primary conidia of the CA form (LC50=34 conidia/mm2) was similar to that of the DA form for young flies. Secondary conidia of the CA form were markedly more infective (LC50=0.36 conidia/mm2) than primary conidia of either form. Dose had no significant effect on incubation period for primary conidia of either form, but increased doses resulted in significantly shorter incubation periods for flies exposed to secondary conidia of the CA form. |
