RESEARCH INTERESTS

I am trained as an ecologist, with a specialisation in entomological (pests, entomofaunal diversity) and macro-invertebrate survey work. Areas of special interest include the impact of landscape fragmentation on the distribution of insects, various aspects of environmental ecology with emphasise on pesticide effects on non-target species in agricultural ecosystems as well as the use of aquatic macro-invertebrates as biological indicators in aquatic ecosystems. Investigations on the use of natural biocontrol agents, e.g. entomopathogens, parasitoids occurring in Swaziland is an area I would like to explore further given sufficient funding and time. Preliminary investigations on this aspect could be used as a basis for possible studies in the biological control of economically important species.
A primary component in all the work above is filling the gap on an entomological database within Swaziland. Due to lack of funding, preliminary survey work has been done on select coleopteran families, e.g. Carabidae and Scarabaeidae as well as macro-invetrebates, including both agricultural and riparian ecosystems. More entomological surveys are in the pipeline to fill in this void as well as enhance investigations in other areas of interest.
