Biochemistry, Genetics and Microbiology
I started my PhD in April 2013 at the Forestry and Agricultural Biotechnology Institute (FABI) under the supervision of Prof. Bernard Slippers. My PhD project focuses on the diversity and specificity of the Sirex - Deladenus - Amylostereum complex. Sirex noctilio being a great threat to the pine forestry industry worldwide, makes this project a very important one to combat the pest using the biocontrol agent D. siricidicola. The nematode native range includes North America Europe and Asia. Through years of human breeding and interbreeding, a highly efficient, but also highly inbred line of the nematode (the Kamona strain) has been established throughout Southern Hemisphere plantations. It has become evident that this lack of diversity could be affecting the efficiency of the biological control system. Therefore interest lies in characterizing the global native diversity of D. siricidicola and its potential to be used to improve biological control of S. noctilio.
