Dispersive flight by Triatoma infestans under natural climatic conditions in Argentina

Abstract: Male and female T. infestans were released on two consecutive nights in the salinas of Cordoba Province, Argentina, when air temperatures during the flying period averaged 28.5 degrees C. 136 males (43% of the total released) and 170 females (57%) flew on the first night, and 6 males (18%) and 7 females (27%) on the second. Of these, we recovered 23 males and 14 females within 100 m, and a further female within 200 m, all from the first night's release. The remainder appear to have flown more than 100 m and po… Show more

“…The high incidence of T. vitticeps in domicile during hot months is in agreement with the previous observation of the high temperature correlation and the increased avidity of the insect to seek blood meal (Zeledón & Rabinovich 1981), which is responsible for the starting point and the duration of the flight (Schofield et al 1992). However, it is worth mentioning that no correlation has been found between high temperature and incidence of triatomines, based on data obtained by the National Meteorology Institute, in the 1989/1995 period.…”

“…In a dispersal study performed in the Cochabamba valley at 2,700 m asl, the detection of restricted gene flow between close, but distinct, sylvatic sites (rocky outcrops) was consistent with the hypothesis that the vectors do not disperse by flying at high altitude (Richer et al 2007). Some studies on the ability of T. infestans to fly under more favourable conditions (in the lowlands of the Chaco) pointed out that this species showed flight potential on a village-wide scale and in sylvatic environments (Schofield et al 1992, Vazquez-Prokopec et al 2006. However, the results of Richer et al (2007) suggested that, at 2,700 m asl in the Andes, wild T. infestans gradually disperse over a small distance by walk-ing within a "patch", which might be characterised as a continuous land cover with all necessary resources for the persistence of triatomine populations (Gustafson & Gardner 1996).…”

“…In fact, peridomestic and sylvatic populations are being increasingly involved in the re-infestation of domiciles following control programs (Gürtler et al 1999), as well as in the transmission of T. cruzi to humans in the absence of house colonization by triatomines (Coura et al 1994(Coura et al , 1999(Coura et al , 2002. As suggested by a few studies on triatomine dispersal, their flying capacity may have been somewhat underestimated (Schofield et al , 1992, and need to be assessed more carefully. A possible hypothesis for the Yucatán is that seasonal changes in blood meal availability, such as from opossums, one of the main blood source for T. dimidiata (Quintal & Polanco 1977), may induce an increase in sylvatic/peridomestic bugs foraging activity leading to a transient infestation of the domestic areas.…”
