Mortality was 100% for 0.5 and 1.0% (AI) concentrations on painted and plywood surfaces for the entire study. Diazinon on treated glass declined to near the limit of detection, with no mortality at 4 weeks for both concentrations. Diazinon residues decreased by 35% on plasterboard at 4 weeks. However, mortality was reduced to 11%at 4 weeks on plasterboard treated at the 0.5% rate and 44% at the 1.0% rate. Decreased cockroach mortality on plasterboard may have been due to absorption or binding of diazinon to the paper covering on the treated surface.}, number={4}, journal={JOURNAL OF ECONOMIC ENTOMOLOGY}, author={ROPER, EM and WRIGHT, CG}, year={1985}, pages={733–737} }
