Effects of parathion and 2,4-d to eggs incubation and larvae hatching in Chasmagnathus granulata (decapoda, brachyura)

1. Effects of the pesticides parathion and 2,4-d on the crab Chasmagnathus granulata during eggs incubation period were assessed. 2. Abortion of egg masses carried by the females occurred. 3. ec50 values for clutch loss were 34 μg/l for parathion and 7.4 mg/l for 2,4-d. 4. When hatching occurred, pa...
