I am currently completing my PhD (Entomology) at FABI and the department of Zoology and Entomology at the University of Pretoria.

I completed a BSc (Entomology) at Rhodes University, Grahamstown. Thereafter I completed my MSc at FABI and the department of Zoology and Entomology, University of Pretoria. My research focused on the distribution, diversity and prevalence of two genetically distinct lineages of the minute gall wasp and pest on EucalyptusLeptocybe invasa (Hymenoptera: Eulophidae). This wasp induces galls on a variety of Eucalyptus species and has become a serious economic threat to Eucalyptus plantations worldwide. The distribution and prevalence of two biological control agents and parasitoids of L. invasa (Selitrichodes neseri (Hymenoptera: Eulophidae) and Ophelimus maskelli(Hymenoptera: Eulophidae))Furthermore, two Megastigmus species (M. zebrinus and M. pretorianensis) (Hymenoptera: Toryimidae). The roles these wasps adopt with each other were researched through dissections and the use of species specific primers/restriction enzymes. 

 

 

 

My PhD will expand on my MSc. This includes a national monitoring scheme of over 5 years worth of data. The establishment of isolated cultures of two cryptic species belonging to the genus Leptocybe. The investigation of potential hybridization between these two cryptic species. Furthermore, the exploration into host specify of the gall community that surrounds these gall forming wasps.
