title: Subchronic exposure of Biomphalaria glabrata eggs to aridanin and niclosamide.
abstract: Treatment of 3-day-old Biomphalaria glabrata eggs with aridanin caused a knock-down effect on the prehatch snails, making this group the most susceptible. The development and hatching of 0- to 1-day-old eggs could not be prevented but was prolonged by continuous exposure to aridanin (0.5-10 mg/l). Prehatch snails were less susceptible than juvenile and adult snails. Niclosamide (0.625-0.35 mg/l) arrested the development of B. glabrata. The results predict a poor action of aridanin as an ovicidal agent in the control of snail intermediate hosts of schistosomiasis.
