Response of invasive plants to biocontrol and herbivory
Biocontrol remains an important means of controlling invasive plants in South Africa and the success of insect agents is influenced by environmental conditions and plant responses. My interest has been to quantify plant responses to biocontrol agents and determine how these are influenced by environmental conditions. This work has been conducted in collaboration with Prof. Martin Hill (Zoology and Entomology Department, Rhodes University).
