| Abstract: | Leptodius floridanus (Rathbun) (Decapoda: Xanthidae) larvae were fed dieldrin-contaminated Artemia nauplii throughout their development to megalopa. Sublethal effects were noted at dieldrin concentrations as low as 5.49 ppm, and no larvae completed their development when fed Artemia containing 33.0 ppm dieldrin. Organochloride pesticide residues were measured in zooplankton collected from Onslow Bay, North Carolina, USA. These residue levels were found to be much lower than those found to affect Leptodius larvae in the laboratory. |
