MARIOTTINI, Yanina; WYSIECKI, María L. De  and  LANGE, Carlos E.. Fecundity and postembrionic development of Baeacris pseudopunctulatus (Orthoptera: Acrididae: Melanoplinae) under controlled conditions. Rev. Soc. Entomol. Argent. [online]. 2008, vol.67, n.3-4, pp.135-138. ISSN 0373-5680.

Five cohorts of Baeacris pseudopunctulatus Ronderos were monitored under controlled conditions (30º C, 14L:10D, 40% RH) in order to determine some fundamental aspects of its biology and reproduction. Five nymphal instars were recorded. The observed developmental time in nymphs was 30,14 ± 0,85 days. Mean duration of cohorts was 10,66 ± 1,7 weeks. Mean number of egg-pods per female was 3,56 ± 0,52, and mean number of eggs per pod was 15,5 ± 0,6, with a minimum of 10 and a maximum of 22. Mean fecundity (number of eggs per female) was 46,03 ± 6,84. The egg-laying rate was 1,20 ± 0,21 eggs/female/day.

Keywords : Baeacris pseudopunctulatus; Grasshopper; Cohorts; Longevity; Fecundity.
