Different concentration of Dursban were applied to soil to test its efficacy against Microcerotermes championi (Snyder), according to Smith (1979). Mortality during 8 hours exposure at 120 ppm, 240 ppm, 480 ppm,960 ppm, and 1920 ppm was 43.3%, 46.6%, 50%, 53% and 56.6% respectively. One month old treated soil retained toxicity up to the same extent against this species.
LC50 of Dursban for M. championi was 501 ppm. As regards repellency, all the concentrations behaved as repellent.
In order to see tunneling ability of M. championi in soil treated with Dursban, very low concentrations were tried. Microcerotermes championi penetrated soil treated with 15 ppm, 30 ppm and 60 ppm and not at higher concentration.
