Abstract

CHAVEZ-CONTRERAS, Juan Martín et al. Biological parameters of Meccus phyllosomus, Meccus mazzottii and laboratory bred-hybrids. Bol Mal Salud Amb [online]. 2013, vol.53, n.1, pp.73-76. ISSN 1690-4648.

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.
