The stomach was removed, washed, extracted and analysed by TLC. Also five polysulfide derivatives of carbosulfan or of carbofuran [4 (n =2-3) and 51 were detected as minor products (Umetsu and Fukuto, 1982). P. R. (1980) J. Agric.

1975). [14C-ring]Benfuracarbwas applied topically to houseflies. Flies were extracted and analysed at intervals up to 24 hours. Penetration of applied radioactivity was rapid and extensive (65% of that applied). Pathways of metabolism were similar to those for plants (Scheme 2). Principal reactions in the housefly were N-S bond cleavage, oxidation, hydrolysis and conjugation. Benfuracarb was readily decomposed to form carbofuran which was in turn oxidised at the 3-position and at the N-methyl group.
14C-caubonyl]-,[14C-dibutylarnino]-or [14C-ring]-Carbosulfanwere orally administered to rats. Samples of urine, faeces and blood were taken at intervals up to 96 hours. Radioactivity eliminated after 24 hours as C02 Carbarnates Carbosulfan 37 from [14C-carbonyl]carbosulfanrepresented 6 5 4 5 % of that administered. Radioactivity eliminated in urine from [14C-ring]carbosulfanrepresented S O % and from [14C-dibutylamino]carbosulfan>50% after 24 hours. A large was recovered from faeces. The carbofuran was then metabolised via hydrolysis and oxidation to metabolites 7, 8,9 and 10.
