Several populations of the free-living nematode species Rhabditis oxycerca have been reared since 1975 in increasing concentrations of aldicarb and oxamyl. General observations concerning survival, reproductive capacity, morphological changes and possible influence of microflora in the culture media were reported in part I. The present results rcfcr to an exposure level of 380 ppm aldicarb and 400 ppm oxamyl. Tests revealed a resistance index of Ri = 86 to oxamyl of the oxamyl-exposed population and a Ri = 34 of the aldicarb-exposed population to eserine. Biochemical investigations indicated an increased activity of the target enzyme of the nematicidal carbamates, the acetylcholine esterase, in resistant populations. Furthermore the numbers of oxidases and unspecific esterases in resistant Rhabditis populations are increased. Both enzyme systems are supposed to be mainly involved in carbamate detoxification in exposed nematode populations, while the glutathione-S-transferases take no leading part in biochemical mechanisms of resistance.
