Maintenance of a narrow host range by Oxyops vitiosa; a biological control agent of Melaleuca quinquenervia
Host range expansion in insect herbivores is often thought to be mediated by several factors, principal among them are secondary plant metabolites. In weed biological control, the host range of a prospective agent is one of the most important considerations in its implementation. Extensive host testing tests seek to determine the behavioral acceptance and nutritional value of different test pla...
متن کاملHost Plant Quality Factors That Influence the Growth and Development of Oxyops vitiosa, a Biological Control Agent of Melaleuca quinquenervia
t t The Australian weevil Oxyops vitiosa was released in 997 in Florida as a biological control agent of elaleuca quinquenervia. The larvae of this agent are ush-feeders, found only on the growing tips of their ost. Knowledge of this restriction to feeding on the rowing tips and other nutritional requirements may ssist in the establishment and dispersal of this speies. Therefore, O. vitiosa sur...
متن کاملAcquired Natural Enemies of the Weed Biological Control Agent Oxyops Vitiosa (colepotera: Curculionidae)
The Australian curculionid Oxyops vitiosa Pascoe was introduced into Florida in 1997 as a biological control agent of the invasive tree Melaleuca quinquenervia (Cav.) S. T. Blake. Populations of the weevil increased rapidly and became widely distributed throughout much of the invasive tree’s adventive distribution. In this study we ask if O. vitiosa has acquired natural enemies in Florida, how ...
متن کاملEvaluating Acephate for Insecticide Exclusion of Oxyops Vitiosa (coleoptera: Curculionidae) from Melaleuca Quinquenervia
One method of evaluating the impact of insect weed biological control agents is to exclude them from their host with insecticides, thereby enabling comparisons of host fitness between infested and non-infested plants. However, the insecticide must not positively or negatively affect the plant being protected. The insecticide acephate was tested for its effects on Oxyops vitiosa Pascoe and Melal...

The invasive treeMelaleuca quinquenervia (Cav.) Blake is widely distributed throughout peninsular Florida and poses a signiÞcant threat to species diversity in the wetland systems of the Everglades. Mitigation of this threat includes the areawide release campaign of the biological control agentsOxyops vitiosa Pascoe and Boreioglycaspis melaleucaeMoore. We summarize the results of this release e...
