Comparative biology of the two sister species of Triatominae (Hemiptera: Reduviidae) Biologia comparativa de duas espécies irmãs de Triatominae (Hemiptera: Reduviidae)
INTRODUCTION: Triatoma pseudomaculata and T. wygodzinskyi (Hemiptera: Reduviidae: Triatominae) are two Brazilian vectors of Chagas disease. The first is an arboricolous species in sylvatic environment and considered a vector of T. cruzi in peridomestic structures; the second, a rupicolous species in...
