Carbofuran and a series of biscarbofuran polysulfide analogs of carbofuran in acetone were similar in toxicity on a weight basis, with one exception, when applied topically to the thorax of the house fly, Musca domestica L. The one exception, biscarbofuran-N, N′-disulfide, was relatively nontoxic and was found to crystallize extensively on the surface of the cuticle, whereas in comparison the other carbofuran polysulfide analogs showed little or no crystal formation but did have amorphous globular deposits. Methomyl in acetone was toxic to the house fly and showed a slight amount of crystal formation on the house fly thorax when applied topically. However, dicarbasulf, the bismethomyl-N, N′-sulfide analog of methomyl, was relatively nontoxic when topically applied in acetone and showed extensive crystal formation. Application of dicarbasulf in an acetone-kerosene mixture increased toxicity to house flies and dramatically reduced the amount of crystal formation as seen under the scanning electron microscope.
