Insects associated with pecan trees, Carya illinoinensis: characterisation, impact and control Project overview (1 October 2020 – 30 September 2021) During this fiscal year, three principal objectives were pursued: (1) continue with insect surveys in the Hartswater, Prieska and Modimolle regions; (2) investigate the entomopathogenic fungi, Beauveria bassiana and Metarhizium anisopliae, as artificially-induced endophytes in pecan seedlings (establishment) and impact on pecan nut weight (trees); and (3) initiate pheromone-based surveillance and damage-correlation of African bollworm, Helicoverpa armigera, and false codling moth, Thaumatotibia leucotreta, in the Hartswater, Prieska and Jacobsdal regions.Research Report 2019/2020

Pecan diseases
Pecan Diseases
Pecan diseases and health risks in South Africa
A collaborative project, launched in 2017 between SAPPA and the University of the Free State (UFS) is focussing on the study and distribution of pecan diseases in South Africa: Part 1:- Pecan Scab
- Black blotch and die-back
- Alternaria black spot
- White and brown rot
- Black lesions on nuts (Chaetomium species)
- Overall decline of pecan trees
- Fungi associated with the shot hole borer
Polyphagous Shothole borer and fungus infesting Pecan trees
Polyphagous Shothole borer and fungus infesting Pecan trees
A collaborative research project between SAPPA and FABI started in 2018 investigating the PSHB on pecan nut orchards.
The project is on understanding the seasonal patterns as well as the rate of spread of the beetles, and also studying the long-term effects of the fungal infections caused by the PSHB
