Abstract
Accumulation and metabolism of the organophosphate pesticide, phorate by the free-living nematode Panagrellus redivivus was studied under anaerobic conditions and in the presence of carbon monoxide or SKF 525A, and compared with results obtained under normal, aerobic conditions and using heat-killed nematodes. Both phorate hydrolysis and side-chain oxidation were inhibited under anaerobic conditions and with heat-killed nematodes, but only hydrolysis was affected in the presence of carbon monoxide. The much greater phorate accumulation in the nematodes under anaerobic conditions and with carbon monoxide could be explained by this metabolic inhibition. SKF 525A had no significant effect on phorate metabolism or accumulation. The possible mechanisms involved in phorate breakdown by P. redivivus are discussed.
