Abstract

BATTEL, Ana Paula Magalhães Borges et al. Reproductive potential of Chrysoperla externa maintained in different cage sizes in laboratory conditions. Cienc. Rural [online]. 2017, vol.47, n.3, e20160381.  Epub Jan 05, 2017. ISSN 1678-4596.  https://doi.org/10.1590/0103-8478cr20160381.

This study investigated the influence of cage sizes on the survival and reproductive potential of Chrysoperla externa (Hagen). Size of breeding cages significantly affected the reproductive potential of C. externa . Our results indicated that in cages smaller (7.5cm of diameter) than those usually recommended for the rearing of this insect (10cm diameter), females showed higher rates of oviposition. Reduction of space for rearing natural enemies in the laboratory is very important for developing biological control programs.

Keywords : green lacewing; mass rearing; oviposition; predator.
