About My Research

I am currently a PhD candidate in Biological Sciences at the University of Cape Town, Department of Biological Sciences. My research focuses on the molecular and morphological phylogeny of Sycophila and Ficomila parasitoid wasps (Hymenoptera: Eurytomidae) associated with Afrotropical Ficus (Moraceae). The primary objective is to revise the taxonomy of these parasitoid wasp genera in Southern Africa.

In my study, I employ molecular and morphological phylogenetic analyses to examine the congruence of host specificity with their host fig species and assess the degree of co-divergence. This research involves sorting and identifying relevant specimens based on morphological characteristics prior to DNA extraction. Given the limited knowledge of African fauna, I anticipate describing numerous new species. Comprehensive identification keys for all species will be developed and made publicly available on FigWeb (www.figweb.org).

Fig trees, considered keystone species for vertebrate frugivores, are widely distributed in tropical and subtropical regions. Research indicates that these plants are consumed more than any other fleshy fruits. Tropical species of Sycophila and Ficomila primarily interact with Ficus species, either as parasitoids attacking gall-maker larvae or as inquilines feeding on both the larvae and the tissues of large galls caused by Epichrysomallidae (Hymenoptera: Chalcidoidea). These interactions block access to the fig by pollinators as the galls fill the syconium.

By studying these relationships, my research aims to provide a deeper understanding of the impact non-pollinator fig wasps have on the success of pollinators, which is crucial for the propagation of fig trees. Given that fig trees are vital resources in tropical and subtropical ecosystems, this research will contribute to our knowledge of biodiversity and ecosystem dynamics.
