After topical application of c!4-endosulfan to Musca domestica (85, 86) 
or to leafy plants (248), endosulfan sulfate was isolated. Several additional 
metabolites were also found but not identified. Characteristics of the 
unidentified compounds indicated that they were probably conjugates of endo- 
sulfan as either the glucoside, the glucuronide, or the ethereal sulfate. 
After peroral, cutaneous, and subcutaneous application of endosulfan 
to male imagos of the locust (Pachytilus migratorius migratorioides ), four 
metabolites were observed and identified as: endosulfan sulfate; endosulfan 
ether; endosulfan hydroxyether; and endosulfan lactone (77). 
On the basis of NMR and infra-red spectra, the configurations of the 
two isomers of endothal were assigned (1786).
