ABSTRACT

Se reportan datos sobre el ciclo de vida, número de repastos sanguíneos para mudar de estadio ninfal, mortalidad y el porcentaje de hembras de híbridos de M. phyllosomus x M. mazzottii en comparación con cohortes “puras” de M. phyllosomus (Burmeister) y M. mazzottii (Usinger). El ciclo de vida fue significativamente (P<0,05) más corto en las dos cohortes híbridas, respecto de las parentales. En contraste, no se registraron diferencias significativas (P>0,05) entre cohortes en el número de repastos sanguíneos para mudar de estadio ninfal. El porcentaje de mortalidad (41.8%) de la cohorte parental de M. phyllosomus fue significativamente (P<0,05) mayor que los de las tres cohortes restantes. El porcentaje de hembras fue similar (P>0,05) entre las cuatro cohortes bajo estudio.


Data is reported about life cycle, number of blood meal to molt to next instar, mortality and percentage of females on hybrids from crosses of M. phyllosomus x M. mazzottii compared to “pure” cohorts of M. phyllosomus (Burmeister) and M. mazzottii (Usinger). Recorded life cycle was significantly ( P<0,05) shorter in both hybrids cohorts with respect to the two parental ones. In contrast, non significant (P>0,05) differences were recorded in the number of blood meals to molt to next instar when the four studied cohorts were compared. Mortality percentage (41.8%) on the parental cohort of M. phyllosomus was significantly (P<0,05) higher than those in the three other studied cohorts. Female percentage was similar (P>0,05) when the four studied cohorts were compared.
