“…With the increase in the literature regarding the feeding sources of triatomines over the last 30 years, haemolymphagy has been observed in more than 20 species belonging to the genera Belminus ( Lent & Wygodzinsky 1979 , Sandoval et al 2000 , 2004 , 2010 , 2013 ), Eratyrus ( Miles et al 1981) , Psammolestes ( Carcavallo et al 1998 , Noireau et al 2005a ), Panstrongylus ( Carcavallo et al 1998 , Garrouste 2009) , Rhodnius ( Brumpt 1914 , Marinkelle 1965 , Piñero et al 1988) and Triatoma ( Brumpt 1914 , Ryckman 1951 , Phillips 1960 , Lent & Wygodzinsky 1979 , Salvatella & Calegari 1991 , Salvatella et al 1994 , Lorosa et al 2000 , Ruas-Neto et al 2001 , Vezzani et al 2001 , Emmanuelle-Machado et al 2002 , Freitas et al 2005 , Noireau et al 2005a , Silva et al 2005 , Zeledón et al 2010 , Alves et al 2011 , Pontes et al 2011 , Cardozo-de-Almeida et al 2014) . The ability to use haemolymphagy is suggested to represent an important survival strategy under natural conditions for some species, resulting in optimised use of available nutrition resources and an increase in the probability of survival when vertebrate hosts are absent ( Salvatella et al 1994 , Lorosa et al 2000 , Ruas-Neto et al 2001 , Alves et al 2011) .…”
