“…In higher organisms, many metabolic products of DDT have been found. 4,4'-Dichlorobenzophenone (DBP), bis(p-chlorophenyl)acetic acid (DDA), DDD, 1, 1-dichloro-2 , 2-bis(pchlorophenyl)ethylene (DDE), DDMS, DDMU, unsym-bis(p-chlorophenyl)ethylene (DDNU), 2, 2-bis(p-chlorophenyl) -ethanol (DDOH), and 1,1 -bis(pchlorophenyl) -2,2,2trichloroethanol (Kelthane) have all been isolated from mammals and insects exposed to DDT (7,11). Peterson and Robison (12) were able to recover the following metabolites from rats given DDT orally and postulated the metabolic pathway to be: DDT -* DDD > DDMU --DDMS DDNU --DDOH -DDA, or DDT --DDE.…”

“…The extraction and detection methods used should have shown other known DDT metabolites, e.g. dicofol found in Drosophila melanogaster (TstrKAMOTO, 1959, andMENZEL, SMITH, MISKUS &HOSKINS 1961) and ,4edes aegypti, (KIMURA & BROWN 1964), or DDA (di-(4-chlorophenyl) acetic acid) found in body lice (PERRY, MILLER & BUCKNER 1963), but none of these was detected in any of the strains of house flies tested. A small amount of DDE occurred in the surface washings, suggesting that DDT and metabolites may be excreted either in the faeces or through the cuticle, but there was no evidence that more was excreted by resistant than by susceptible insects.…”

“…For the second possibility, no published evidence is available for metabolism of DDT, because most investigators describe only comparison of the enzyme activity but not of the protein amounts or specific activity of enzymes between resistant and susceptible strains. The third possibility should not be ignored because at least three other metabolic pathways of DDT are known in insects: hydroxylation of DDT to dicofol (TSUKA-MOTO 1959), reductive dechlorination to TDE (HooPER 1967), and formation of unknown metabolites probably conjugation via DDA (PERRY et al 1963). Indeed, even in the housefly, the presence of the hydroxylating enzyme system has been suggested in vivo (TSUKA-MOTO 1961) and has been reported in vitro (AGOSIN et al 1961, TSUKAMOTO and.…”
