HERRERA, María E.; DAGATTI, Carla V.  and  BECERRA, Violeta C.. Life table and population parameters of Lobesia botrana (Den. et Schiff.) under laboratory conditions. Rev. Soc. Entomol. Argent. [online]. 2017, vol.76, n.3-4, pp.1-10. ISSN 0373-5680.

Lobesia botrana Den. & Schiff. is a quarantine pest for Argentina. Its recent introduction in Mendoza requires studies of life cycle and population parameters. The aim of this work is to construct a horizontal life table, determine the demographic parameters, the average duration of the pre - reproductive, reproductive, post - reproductive periods, adult longevity, fecundity and fertility under laboratory conditions. The demographic parameters of L. botrana obtained were: intrinsic rate of increase (rm) of 0.137, net reproductive rate (Ro) of 66.82, mean generation time (T) of 30.51, finite rate of increase (λ) of 1.073, and the doubling time (D) of 9.76 days. The gross fecundity obtained (Mx) of 134.84 ± 15.68 eggs per female, the mean duration in days of pre-reproductive periods was 1 ± 0.81, the reproductive 6.25 ± 1.25 and the post-reproductive period of 2 ± 0.68, female longevity 9.25 ± 1.67 and male 8.64 ± 0.83 days.
