Few studies have been published regarding the ecology of North American Triatomines
Phylogenetic approach to the study of triatomines
Collected adult triatomines
and first and fifth instars were identified according to Lent and Wygodzinsky (13).

vectors, reservoir hosts, and previous documentation of canine disease (5,7).
can survive for months in harvested crops; thus, multiple hygiene interventions are potentially necessary along the food production line (14).
In Arizona, humans may be at a greater risk for vectorial transmission of the disease than previously thought because human populations are rapidly expanding into habitats where infected triatomines
(20-22) and wild mammalian reservoirs such as packrats, mice, armadillos, raccoons, and opossums (23-27) are plentiful.
Oral transmission occurs by consumption of foods contaminated with triatomines
or their feces or by consumption of raw meat from infected mammalian sylvatic hosts (3).
In the Brazilian Amazon region, where domiciled triatomines
have not been reported, human cases of Chagas disease have been increasing (2).
His book includes information on diseases transmitted by mosquitoes, ticks, rodents, mites, sandflies, fleas, lice, biting midges, diptera, triatomines
, and cockroaches.
