Insects in the vineyard - ID Photos

Vine Moth



Light Brown Apple Moth





Wingless Grasshoppers & Locusts


Wingless Grasshoppers and locust have been seen in McLaren Vale and Adelaide Hills vineyards. In general levels are low and surrounding grassland and pastures have enough green feed to support the locusts limiting any significant damage to grapevines (below).


Late nymph and adult locust eat green feed during summer. They tend to move from nearby drying pastures and crops into vineyards during December to February where there is a source of green feed. They prefer to feed on tender young shoots and leaves and leave a smooth edge to their feeding area. The vine rows nearest the drying pastures and crops tend to be most damaged.
