Abstract
Association of DDT resistance levels with chromosome inversion polymor phism was investigated in Anopheles arabiensis samples collected from southwestern Ethiopia. The frequencies of the 2Ra, 2Rd, and 3Ra invers ions in 1988 and 1990 between the DDT survivors pooled from the 3 time s of exposure and unexposed controls did not differ significantly. How ever, for 2Rb a significant association was observed (Mantel-Haenszel chi(2), stratified for year of collection = 10.4, P < 0.001). The inve rsion frequency was 56% among unexposed individuals, but it was 64-92% among those surviving exposure.
