Improvements in Routine Xenodiagnosis with First Instar Dipetalogaster Maximus (Uhler 1894) (Triatominae)

The American Journal of Tropical Medicine and Hygiene, 1979
First instar Dipetalogaster maximus proved as effective as third instar Triatoma infestans in detecting circulating Trypanosoma cruzi in patients with chronic infections examined in a routine xenodiagnostic laboratory. Since rearing costs are diminished, D. maximus has now replaced T. infestans as the xenodiagnostic agent in our laboratory.

Dipetalogaster maximus (Hemiptera, Triatominae) for xenodiagnosis of patients with serologically detectable Trypanosoma cruzi infection

Transactions of the Royal Society of Tropical Medicine and Hygiene, 1979
In patients serologically positive for Trypanosoma cruzi infection the three bug species/instar combinations used in xenodiagnosis showed third-instar Dipetalogaster maximus to be more efficient in detecting circulating trypanosomes than the first instar of the same species which, in turn, is more sensitive than third-instar Triatoma infestans.

Value of first-instar triatomines (Hemiptera; Reduviidae) in comparative xenodiagnosis of Trypanosoma (Schizotrypanum) cruzi

Parasitology Research, 1987
A direct correlation was shown between bloodmeal intake in xenodiagnosis and subsequent infection rate with Trypanosoma (S.) cruzi, in first-stage nymphs of Panstrongylus megistus Burmeister. The parasitaemia of different hosts, or of the same host at intervals, thus can be compared indirectly by the proportion of first-stage nymphs infected in ...
