Resumen:
The hyperactivity produced in third instar nymphs of Triatoma infestans by their exposure to films of deltamethrin or cis-permethrin was evaluated. Both pyrethroids produced a significant increase in locomotor activity at 26 and 36 °C, but not at 16 °C. At 26 °C, only deltamethrin produced hyperactivity when topically applied on the dorsal side of the nymphs abdomen. However, both pyrethroids produced hyperactivity when topically applied on the head of the nymphs. Hyperactivity was not observed when nymphs were treated with N-ethylmaleimide (20 ìg/insect) before exposure to the pyrethroids. The effect of both insecticides on locomotor activity reversed the inhibitory influence on locomotion elicited by contact with the walls of the experimental arena (thigmotaxis).
