Antennal Sensilla Patterns Indicate Geographic and Ecotopic Variability Among Triatoma infestans (Hemiptera: Reduviidae) Populations

Antennal sensilla patterns were used to explore intraspecific variability among Triatoma infestans</it> (Klug) from domestic habitats in Argentina and Bolivia, and from sylvatic habitats in Bolivia. The sensilla pattern was effective in distinguishing individuals at sexual, ecotopic, and geographic levels, and supported the idea of a lack of gene flow between sylvatic and domestic habitats.
