| Abstract: | The livers from a naturally occurring insecticide-resistant mosquitofish population were examined cytologically and compared to liver preparations from a susceptible population. There was a marked increase in cell size and lipid inclusions in the hepatocytes of resistant mosquitofish as compared to susceptible mosquitofish. The pronounced lipid inclusions in the liver preparations of resistant mosquitofish remained essentially unchanged in mosquitofish starved for up to 2 weeks. No observable differences were noted in any cellular organelles. |
