Determinação do período de desenvolvimento e da viabilidade das desovas de duas populações de Biomphalaria glabrata e Biomphalaria tenagophila (Mollusca, Planorbidae)

Abstract: tenagophila).Recordamos aqui, que estas espécies de planorbídeos são as grandes responsáveis pela m anutenção dos focos de Schistosoma mansoni n a região Centro-Sul do país.O estudo com parativo do com porta m ento e dos dados biométricos dessas duas populações é im portante tendo-se en* vista a competição observada entre elas (2) além da im portância epidemiológica já res saltada no parágrafo anterior. MÉTODOEm um mesmo dia foram depositados em "beakers" de 250 ml, dois caramujos da mesma espécie e população.… Show more

“…He observed a hatch rate for B. glabrata that ranged from 37.7% to 56.0%. KAWAZOE 16 found an average of 95.8% for B. glabrata in pairs and MAGALHÃES & LUCCA 18 obtained a rate of 91.6% for B. glabrata in groups. In this paper, the hatch rates for B. glabrata in groups and individually show significant differences for some age groups, with a significant drop in the hatch rate for the groups is the last age group (Table 3).…”

“…At the first week post exposure (p.e.) (Magalhães & Lucca 1971, Kawazoe 1977.The physiological stress factors, as temperature variations (Pimentel-Souza et al 1990), lightness (Barbosa et al 1987), starvation (Livingstone & Zwaan 1983), and parasitism by larval trematodes (Looker & Etges 1979, Sullivan et al 1985, Cooper et al 1994, Cousin et al 1995 have been pointed as able to influence the reproductive biology of the snails.There are few studies on the interference of plants that exhibit moluscicide action with the reproductive activity of the snails, intermediate host of helminthes. The reproductive capacity of B. alexandrina is reduced when it was exposed to Allium sativum, A. cepa, and Atriplex halimus (Mantawy 2001, Tanatawy 2002.…”
