Diallyl disulfide (DADS), a major insecticidal principle of garlic, L, has low environmental persistence; there is an exponential loss of [35S] DADS from the treated water with respect to time. Compared to larvae, pupae of Say, exhibit higher tolerance to this pesticide. Both, larvae and pupae metabolise [35S] DADS to inorganic [35S] sulfate.
