Comparison of In Vivo Versus In Vitro-Reared Catolaccus Grandis in the Field

J.A. Morales-Ramos, M.G. Rojas, R.J. Coleman, S.M. Greenberg, K.R. Summy, E.G. King


The movement, searching capacity, and survival under field conditions of in vitro and in vivo reared Catolaccus grandis (Burks) females were compared in Ricardo and Lyford, TX. Dispersal ability and searching capacity was not significantly different within the 30-m radius among parasitoid females reared by the two different methods. However, a significantly higher proportion of stations with parasitism was recorded from in vivo- reared C. grandis at a 60 m radius. These results indicate that in vitro-reared C. grandis have a significantly lower dispersal ability, but, their searching capacity is not significantly affected.
