Laboratory experiments were conducted to determine the effects of mirex, methoxychlor and malathion on the larval development of Callinectes sapidus from the time of hatching until the first crab stage is reached. For comparison, similar investigations were made to ascertain the effects of methoxychlor and malathion on larval development of Rhithropanopeus harrisii. The effect of a range of concentrations of each insecticide on survival of larvae of C. sapidus and R. harrisii was determined, as well as concentrations which were sublethal and lethal. Zoeal and total development to the first crab stage of R. harrisii and C. sapidus was prolonged in relation to increased concentrations of methoxychlor and malathion. Other sublethal effects of methoxychlor and malathion included abnormal development of the pleopods of male R. harrisii and male C. sapidus early crab stages, and autotomy of the legs of R. harrisii megalopa and early crab stages. The developmental stages in which larvae are particularly sensitive vary in the two species and with the three insecticides.
