This paper has shown that temephos, in actual field applications as a mosquito larvicide, behaves in much the same way as was predicted by Henry et al. (1971) and Sanders et al. (1981). The results indicate that the pesticide remains intact in water up to 48 hours, and residues as high as 62 µg/l were found. A problem of stabilization in this study was overcome by using mineral oil as an extracting solvent until the samples could be returned to the laboratory. The two new methods presented for analysis, although similar to methods already published, incorporate some newer technology.
