Abstract
Influence of the blood meal source on life cycle, mortality, and fecundity of 2 cohorts of recently colonized Mexican Meccus longipennis, fed on hens (H-cohort) or rats (R-cohort) were evaluated in laboratory conditions. One hundred twelve nymphs (56%) (H-cohort) and 102 nymphs (51%) (R-cohort), completed the cycle. The average time from Nymph I to adult was 209 ± 41 days (H-cohort) and 239 ± 28 days (R-cohort), taking an average of 1.8 (H-cohort) and 1.9 (R-cohort) blood meals per nymphal stage (range 1-6). The average span in days for each stage from the H-cohort was 20.8 for Nymph I, 24.5 for Nymph II, 38.8 for Nymph III, 56.1 for Nymph IV, and 72.5 for Nymph V, and it was 20.2 for Nymph I, 23.1 for Nymph II, 43.2 for Nymph III, 68.8 for Nymph IV, and 75.4 for Nymph V from the R-cohort. The mortality percentage was 44% (H-cohort) and 49% (R-cohort). The average number of eggs laid per female in a 9-month period was 484.1 (range 351.1-847.8) in the H-cohort, whereas the average number of eggs was 442.3 (range 288.5-720.5) in the R-cohort. No significant differences (P > 0.05) were recorded among cohorts fed on the studied blood meal sources, different from most previously studied Triatominae species, perhaps due to a high degree of association of M. longipennis with chickens and hens as much as with mammals under natural conditions on human dwellings.
