Flight Initiation in Triatoma infestans and T. melanosama (Hemiptera, Reduv
iidae)- The flight initiation of T. infestans, the main vector of Chagas di
sease in the Southern Cone countries of Latin America, and of the closely-r
elated species T, melanosoma was studied in laboratory. The results demonst
rated that after the beginning of observations the peak of the flight activ
ity was about 14 days after feeding in both species and it was usually more
marked in the females than in the males, but there were no significant dif
ferences in the flight behaviour of the two species.
