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