Feeding and mating deterrency by sulfhydryl reagents in Triatoma infestans.


Topical application of different sulfhydryl (SH) reagents in acetone solution resulted in a deterrence of the feeding activity of Triatoma infestans nymph V. The ED50 for topical application of N-ethylmaleimide (NEM), the more active compound assayed, was 8.9 micrograms/insect. This effect showed a dose-dependent reversibility.
