I am the programme leader of the Macadamia Protection Programme (MaPP) at FABI. The Macadamia Protection Programme is a collaborative venture between the Southern African Macadamia Growers’ Association, the Agricultural Biotechnology Institute (FABI) and the University of Pretoria. The overall goal of MPP is to provide biological information required to control pests and diseases of importance to the Southern African Macadamia industry.

 

Currently, a number of insect pests are of major concern to the macadamia industry. Most notable is a complex of stink bugs, of which Bathycoelia natalicola (the two-spotted stink bug) are the most dominant and damaging. The other is the nut borer complex (Lepidoptera) which includes Thaumatotibia leucotetra (False codling moth) and Thaumatotibia bactracopa (Macadamia nut borer). MaPP research will focus on the biology and life cycles of these insects, their population biology, structure and diversity. With regards to diseases, macadamia husk rot, a fungal disease of the pericarp, has become more prevalent during the last few growing seasons and is also of growing concern to the industry. A detailed investigation of the primary causal agent of this disease is also a MaPP research focus area.
