Abstract/Contents: | "Field studies were done to determine whether continuous exposure to the systemic insecticides aldicarb, carbofuran, disulfoton, and terbufos would induce or select for insecticide-resistant greenbugs, Schizaphis graminum (Rondani). The extent of resistance was determined with a surface residue bioassay for each of the insecticides. In field experiments, greenbug populations exhibited 21- to 104-fold increases in resistance to disulfoton. Greenbugs exposed to the other insecticides did not exhibit significant increases in resistance. Greenhouse studies were done to determine if disulfoton resistance resulted from a change within a genotype (greenbug clone) or was simply the result of selection of resistant genotypes from a genetically diverse population. Greenbugs originating from a single aphid susceptible to insecticides developed 65- 300-fold increases in resistance. Similar results were obtained when the study was repeated with progeny from a different greenbug. These results indicate that resistance developed within greenbug clones after exposure to disulfoton for 3 wk or longer. When resistant greenbugs were tested for cross-resistance to cross-resistance to carbofuran, dimethoate, malathion, and terbufos, a significant increase in cross-resistance to dimethoate (nine-fold) and terbufos (two-fold) was observed, but cross-resistance to carbofuran and malathion was not significant." |
