Biocontrol of false codling moth

SA Fruit Journal: February / March 2024

Research confirms the potential of entomopathogenic fungi and nematodes to counter the soil stages of this key pest.

False codling moths damage table grapes and many other crops. Chemical crop protectants are important to false codling moth control but environmentally friendly alternatives must be identified.

Entomopathogens – organisms that cause insect disease and death – could be a greener and healthier alternative to chemical crop protectants. Previous research demonstrated that entomopathogenic fungi and nematodes from South African soils can kill different life stages of false codling moths.
A recent project co-funded by SATI and Hortgro and led by Profs Pia Addison and Antoinette Malan of the Department of Conservation Ecology and Entomology at Stellenbosch University assessed how these local entomopathogens affect larvae and pupae of false codling moths when applied to soil. Trials in soil are essential because false codling moth larvae pupate in soil.
