Field-based rates of population increase for Oxyops vitiosa (Coleoptera: Curculionidae), a biological control agent of the invasive tree Melaleuca quinquenervia
Florida Entomologist 85 (1), 286-287
Abstract: The classical weed biological control agent Oxyops vitiosa was introduced into south Florida in 1997 to aid in the suppression of the invasive weed Melaleuca quinquenervia. As part of our on-going post release evaluations, we estimated the population growth rate of O. vitiosa under field conditions. The intrinsic rate of increase, r, was estimated as 2.44 and the time required for an O. vitiosa population to double is 3.41 months.
