Olive trees are well adapted to hot and dry Mediterranean climates, but even they can suffer from sunburn (also called sunscald) when exposed to intense sunlight, heat stress, or when bark that was previously shaded becomes suddenly exposed. In mature or neglected/abandoned groves - especially those with heavy pruning or thin canopies - the risk can increase significantly.
Green Vegetable Bug (GVB), Nezara viridula, is a sap-sucking “stink bug” that is generally considered a minor or sporadic pest in Australian olives. However, under certain conditions - particularly in warm, humid olive-growing regions - GVB infestations have caused severe damage in conjunction with fungal diseases. In northern New South Wales and southeast Queensland, heavy GVB activity combined with anthracnose (olive fruit rot) has led to crop
