“…They are generally above 80% (Zeledón et al 1970b, Rabinovich 1972, Zárate 1983, Braga et al 1998, Cabello & Lizano 2001, Gomes & Silva 2001, although percentages less than 75% have been recorded for most Mexican triatomines, such as M. mazzottii (58.7%) (Malo et al 1993 Egg hatching rates in M. picturatus in this study (78.1% on the cohort fed on hens and 82.1% in the cohort fed on rabbits) reflects the similarity between conditions in the natural habitats of M. picturatus and those present in laboratory conditions. Mortality showed an irregular pattern.…”

“…Compared to the life-spans reported for other fed triatomines, the life-span we observed for T. brasiliensis females (90-120 days) is similar to Triatoma gerstaeckeri and Triatoma sanguisuaga (Wood 1964) but considerably shorter compared to adult life-spans of over 200 days recently reported for some triatomines (Martinez-Ibarra & Katthain-Duchateau 1999, Cabello & Lizano 2001, Wolff et al 2004. Conversely, the life-spans we observed for unfed animals are similar to those reported for unfed Triatoma lecticularia (Jurberg & Costa 1989) and unfed T. brasiliensis (Costa & Perondini 1973).…”

“…If we calculate the same rate in other species of triatomines (sum of developmental periods of 4th and 5th instar nymphs/sum of developmental periods of 1st, 2nd and 3rd instar nymphs) we find that this is not the case for them. (Zeledón et al 1970, Galvão et al 1995, Martínez-Ibarra et al 1999, 2003, 2007, Cabello & Lizano 2001, Rocha et al 2001, Emmanuelle-Machado et al 2002, Wolf et al 2004, LuitgardsMoura et al 2005, Villacis et al 2008). …”

1972). Later on, three more female specimens were found in airplanes in Miami, United States, one from Honduras and two from Guatemala, the latter together with bromeliad plants in air freight (Lent & Wygodzynsky 1979). The first male specimen was found near the town of Santa Cruz, Guanacaste Province of Costa Rica (Sherlock & Morera 1988). Carcavallo et al. (1996) did an external morphological study, with scanning electron microscopy, of another male specimen, collected in Santa Rosa, Guanacaste Province, Costa Rica. More recently, the natural habitats of T. ryckmani were discovered in a semiarid region of El Progreso Department, Guatemala, in cacti (Stenocercus eichlamii) and epiphytic bromeliads (Tillandsia xerographica). In the first instance, all instars of the bug were found in the dry portions of the cactus (Marroquín et al. 2004a, Monroy et al. 2004; in the second situation, colonies of the bugs were also found within the leaves of the bromeliads growing on trees, including the cacti (Marroquín et al. 2004b). The species has also been found in at least four Departments of Nicaragua in small numbers in houses, under intra and peridomiciliary conditions (Marín et al. 2006 Here we describe, for the first time, the entire life cycle of T. ryckmani under laboratory conditions and the blood patterns of the different instars from specimens collected under natural conditions in Guatemala. MATERIALS AND METHODSA colony was started from specimens captured in June 2005 in bromeliads from a semidesertic area of the Department El Progreso, Guatemala, 89 km from the capital. The climate is hot and dry with a mean maxima temperature of 34.3°C (2003-2008) and a mean annual rain fall of 762.2 mm for the same period.A cohort was initiated with 121 eggs laid, during a period of six weeks, by one female captured as a 5th instar nymph. The eggs, obtained during different days, were separated in nine groups of 8-18 eggs, by date of oviposition, in 10 cm diameter plastic Petri dishes with filter paper on the bottom. They were incubated at a constant temperature with relatively little variation during the experiment (mean ± SD: 26.0 ± 0.37) and 62.0 ± 3.32 relative humidity.Each group was fed on anesthetized hamster (0.25 mL of a mixture of Ketamine, 3 parts and xylazine, 1 part) by xenodiagnosis in a small box, during 40-60 minutes, every two weeks and evidence of ecdyses was monitored daily. First instar nymphs were fed at 4-5 days after hatching. Up to the 4th instar, the nymphs required from 2-4 meals for molting; 4th and 5th instars required 5-7 meals and 9-12, respectively, even though they usually fed readily to repletion.The sources of blood meals of 37 insects, obtained from T. xerographica, were collected individually from the stomach in separate filter papers for each one and after eluded they were identified by the capillary tube precipitin test with antisera against 15 different hosts (human, fowl, dog, cat, horse, goat, cow, pig, sheep, rodent, opossum, armadillo, toad, lizard and insect hemolymph), following th...
