Triatoma gerstaeckeri
kissing bug, blood-sucking conenose
Triatoma gerstaeckeri is a triatomine bug (subfamily Triatominae) and a documented vector of Trypanosoma cruzi, the protozoan parasite causing Chagas disease. Adults measure 20–30 mm in length. The species occurs from the southwestern United States (New Mexico, Texas) through northeastern Mexico, occupying dry scrubland habitats with strong associations to woodrat (Neotoma) nests. It exhibits paurometabolous development with five nymphal instars before adulthood. The species is notable for its relatively high T. cruzi infection rates in some populations and its propensity for peridomestic occurrence near human habitation.
