Abstract

The influence of plant size on attack rates of Oxyops vitiosa, an introduced herbivore of Melaleuca quinquenervia.

Abstract

Oxyops vitiosa Pascoe (Coleoptera: Curculionidae) was released in Florida in 1997 as a biological control agent of the invasive tree Melaleuca quinquenervia (Cav.) S.T. Blake. Three years after release, the weevil's dispersal into three replicated M. quinquenervia stands was monitored to determine if O. vitiosa preferentially selects larger trees during patch colonisation. Data indicated that tree size did not influence the likelihood of an attack by O. vitiosa and smaller individuals within host patches did not escape herbivory through enemy-free space.
