Abstract

In view of the fumigant action of dichlorvos, monoethanolamine was used for its analysis in air, to determine the saturation concentrations, Volhard's titration and colorimetric procedures being followed for the analysis. In addition, the conventional enzymatic method was tested. The results were variable, but the techniques could be used. Efforts to design a bioassay method using adults of Sitophilus oryzae (L.) to determine the concentration in air proved difficult owing to breakdown of dichlorvos to dichloroacetaldehyde and other lower-boiling compounds.
