SUMMARY. Unpigmented nymphs and adults of the corixid bugs Sigara dorsalis and Corixa punctata were found in ponds treated with the aquatic herbicide dichlobenil. Tissue residues accumulated rapidly in nymphs exposed to dichlobenil, and pigmentation was inhibited during ecdysis. However, dichlobenil residues were rapidly eliminated from the tissues of unpigmented nymphs placed into clean water, and pigmentation returned during the following ecdysis.
