Life-trait parameters of S and R lineages at F9 generation in comparison with the Rockefeller strain.

Mean ± standard deviation are shown in all cases. Numbers followed by the same letters do not differ significantly (ANOVA, p>0.05). The last two columns (“average reduction”) compare S and R groups with the Rockefeller strain and R with S group.(1)Larvae development is the rate of pupae formed up to the 6th day after larval hatching.(2)Longevity is represented by the mean survival rate at the 30th day after adult emergence.(3)Blood meal engorgement refers to the females' weight after / before bloodfeeding.(4)Percentage of blood fed females that laid eggs.(5)Mean number of eggs laid by bloodfed females.(6)Rate of larvae hatching.
