Predação e foresia (ocasional?) entre imaturos de Simuliidae (Diptera: Culicomorpha) e Asolene (Pomella) Megastoma (Sowerby, 1825) (Mollusca: Gastropoda: Ampullaridae) Predation and phoretic association (occasional?) among immature stages of Simuliidae (Diptera: Culicomorpha) and Asolene (Pomella) megastoma (Sowerby, 1825) (Mollusca: Ampullaridae)

Abstract

The predation and phoretic association (occasional?) among simulids and mollusks are being registered here for the first time on the Neotropical region. These inter-relations observations were obtained among Asolene (Pomella) megastoma (Sowerby, 1825) and the simulids: Simulium (Thyrsopelma) Orbitale Lutz, 1910; Simulium (Psaroniocompsa) spp. The material studied is proceeding from the Uruguai river Hidrological Basin. Based on the mollusks natural habitat, it is here suggested his use as a possible integrated management element for simulids species which immature stages live on mighty river with rocks.
