“…These mean feeding times were similar to those for M. spinolai, T. rubida and T. protracta (both Triatoma species from southwestern USA) and for R. neglectus and R. robustus (Alzamora et al 2007, Klotz et al 2009, Barreto-Santana et al 2011, Reisenman et al 2011). According to Zeledón et al (1977), species that feed longer than 10 min could be considered potentially important vectors of T. cruzi because prolonged vector-host contact could increase the probability of the interruption of feeding, thereby increasing the risk of contact with the faeces of these insects.…”

“…Similar behaviour was recorded for cohorts of Mepraia spinolai (Porter), T. rubida (from southwestern USA), R. colombiensis, R. prolixus, R. neglectus and R. robustus, which are considered potentially important vectors for the transmission of T. cruzi (Alzamora et al 2007, Arévalo et al 2007b, Klotz et al 2009, BarretoSantana et al 2011, Reisenman et al 2011. The short mean time lapse before the beginning of feeding implies efficient feeding behaviour.…”

Biological information is widely available for the 13 most common domestic triatomines (Hemiptera: Reduviidae: Triatominae) among the 30 species described in Mexico (Martínez-Ibarra et al. 2007, Salazar-Schettino et al. 2010). Information about the remaining species is scarce, primarily because these species have rarely been collected and are difficult to raise under laboratory conditions. Three of these rare species are Triatoma recurva (Stal), Triatoma protracta (Uhler) and Triatoma rubida (Uhler). Although these three species are considered to be of low epidemiological importance, specimens of at least two of these species (T. recurva and T. rubida) collected from inside human dwellings were found to be infected with Trypanosoma cruzi (Paredes-González et al. 2001, Licón-Trillo 2006, Breniere et al. 2010, Licón-Trillo et al. 2010. Studies on the behaviour of triatomine species provide a greater understanding of the habits of these insects and therefore facilitate improved decision-making regarding the priorities for vector control. To our knowledge, there has been no study of the biological parameters (life cycle and feeding and defecation behaviours) of T. recurva; in contrast, two recent studies were devoted to the examination of certain behaviours of T. protracta (Martínez-Ibarra et al. 2007, Klotz et al. 2009) and three studies focused on T. rubida (Martínez-Ibarra et al. 2005, Klotz et al. 2009, Reisenman et al. 2011. Even though the biological parameters of the two latter species have been studied previously, it is necessary to determine the particular behaviours of geographically distinct populations of the same species because it is likely that differing environmental conditions result in different behaviours for distinct populations of the same triatomine species (Licón-Trillo et al. 2010).As part of a series of studies on the biology of Mexican Triatominae, a study of the feeding and defecation behaviours and the life cycles of three Triatominae species of secondary importance in the transmission of T. cruzi to human populations in Mexico was conducted. MATERIALS AND METHODSA laboratory colony of T. recurva established in 2009 from specimens collected in Jesús María, Nayarit, Mexico, was used. A colony of T. protracta (morphologically similar to the synonymised subspecies protracta) was established in 2008 with specimens originally obtained from Caborca, Sonora, Mexico. In addition, a colony of T. rubida (morphologically similar to the synonymised subspecies uhleri) from Saucillo, Chihuahua, was included. The colonies were maintained at 25ºC ± 1ºC and 50% relative humidity (RH) ± 5% RH to match the typical habitat conditions of the three species. The colonies were fed on immobilised and anaesthetised New Zealand rabbits on a weekly basis. These rabbits were anaesthetised following the Norma Official Mexicana regulations with 0.25 mL/kg of ketamine delivered intramuscularly (SAGARPA 1999
