Seasonal variations in active dispersal of natural populations of Triatoma infestans in rural north-western Argentina
The flight dispersal of Triatoma infestans Klug (Hemiptera: Reduviidae) is one of the main mechanisms determining community re-infestation after control interventions. An empirical model of flight initiation coupled with data from a longitudinal study predicted that the flight dispersal of T. infest...
