The tolerance to the organophosphorus insecticide malathion in nimphs
V of Triatoma infestans was notabily higher at the end of this larval
stage. The possibility of this differential toxicity response dependen
t on nimphs V age were due to changes in the detoxifying capacity medi
ated by hydrolases or glutathione transferases. The experimental evide
nces obtained would indicated that the malathion carboxyesterases woul
d not be the primary cause of the differential toxicity but the glutat
hione transferases and phosphorotriesterases could contribute to expla
in this phenomenon.
