Residual activities of various combinations of application rates and times of 14C-chlorpyrifos-labeled water solutions of Dursban 4E were evaluated under laboratory conditions on painted wood surfaces with adult male Orlando normal (insecticide-susceptible) strain Blattella germanica (L.). A standard control procedure that utilized an initial application of 0.50%(AI) Dursban and subsequent monthly applications of 0.25%(AI) Dursban was shown to produce insufficient availability of chlorpyrifos on the test surfaces between treatments to provide acceptable control of B. germanica under laboratory test conditions. A theory was proposed to explain measured levels of chlorpyrifos with different treatment combinations.
