Description

Protective efficacy of a synthetic pyrethroidlike compound, ethofenprox, was investigated in the laboratory against the Formosan subterranean termite workers, compared with chlordane and S-421.<BR>In wood treatment, ethofenprox in itself seemed to be at least twenty times more protective than chlordane at the concentration level against the termite attack. Furthermore, ethofenprox was more effective than chlordane even after various severe weatherings of wood, when treated at the same concentration.<BR>In soil treatment, ethofenprox was found to have almost the same initial and residual efficacy as chlordane or S-421 against the termite tunneling in clay loam and also to have more residual efficacy in the case of sandy loam.<BR>From the results obtained here, residual efficacy of ethofenprox considered to be superior to organophosphorus compounds being used for termite control, as compared to the results reported previously.<BR>Besides, it showed that the addition of each S-421 and Sanplas (3-ethoxycarbonyloxy-l-bromo-1, 2-diiodo-l-propene) to ethofenprox gave a synergistic and durable effect on ethofenprox, respectively.<BR>Considering the low toxicity of ethofenprox to mammals, this compound is expected to be one of promising chemicals having a good chance of practical use.
