Abstract

A study was carried out to set up a practical application of piperonyl butoxide (PB) for the reduction of organophosphorus insecticide-toxicity to kuruma prawn Penaeus japonicus. The absorption and excretion of PB administered through the diet to kuruma prawn was ex amined, compared with the case of exposure to PB-seawater. The concentration of PB in the prawn reached a maximum of 13µg/g at 3-h after feeding with a 1% PB-diet for 6h, which was a similar level to the PB in kuruma prawn exposed to 1ppm PB-seawater for 12h. By feeding with a 1% PB-diet, the survival times of kuruma prawn exposed to fenitrothion (0.01ppm), malathion (0.2ppm), dioxabenzofos (0.4ppm), phenthoate (0.1ppm), and diazinon (0.1ppm) were extended by ca. 11, 5, 5, 3, and 2.5 times over those of the respective control prawns fed with a PB-free diet. However, PB was not effective in reducing the toxicity of dichlorvos (1ppm) (a typical oxo-form insecticide) to kuruma prawn.
