Physa sp.

Unknown Fish exposed to radiolabeled diflubenzuron for33 days contained about 6% of the parent diflubenzuron vs. 54% for alga (Oedogonium cardiacum), 82% for snail (Physa sp.), and 94% for larvae of mosquito (Culex pipiens quinquefasciatus) 42... [Pg.1003]

After first treatment, reduction within 1 week of 3 species of cladocerans (Daphnia laevis, Ceriodaphnia sp., Bosmina longirostus sp.), and 2 species of copepods (Cyclops sp., Diaptomus sp.). No recovery of Daphnia and Ceriodaphnia for 6 months, but Bosmina reappeared 11 weeks later. Diaptomus was depleted for 4 months, but Cyclops recovered in 6-7 weeks. The amphipod Hyallela azteca was eliminated within 4 weeks, and no recolonization was evident after 6 months. No adverse effects on oligochaetes, snails (Physa sp.), or ostracods (Cyprodopsis sp.). After second treatment, temporary reduction in Cyclops and Bosmina, and no significant effects on ostracods, snails, or worms... [Pg.1006]
