Pest ID cards
These cards have been created in partnership with the Farm Services Market Access Team and Australian Table Grape Association.
These cards can be used in the field on farms where grapes are intended for China.
To use them simply print them, trim them, fold in the middle to create a two sided card and laminate. Black Plague Thrips (Haplothrips froggatti), Tubular Black Thrips (Haplothrips victoriensis), Grape leaf rust mites, Redback spider (Latrodectus hasselti), Long-tailed Mealybug (Pseudococcus longispinus), Light Brown Apple Moth (LBAM), Bunch mite (Brevipalpus californicus), Argentine Ants are presented in this image gallery:
Argentine Ant (Linepithema humile)
Argentine ants are small (2.5-3mm) brown ants with a single node in the waist. They are typically found travelling in well defined trails between nests and food sources. Argentine ants have an impact in vineyards by protecting honeydew producing insects.
Look for: Presence of ants and bark damage. During packing, special attention must be paid to argentine ants to avoid this pest from contaminating the grapes and packing boxes.
Bunch Mite (Brevipalpus californicus)
Bunch mite adults are microscopic (0.3mm long), flat, shield -shaped and are reddish-brown in colour. Their eggs are oval and bright red and deposited throughout the vine. In Spring bunch mites feed on developing canes and later on the under - surfaces of leaves.
Look for: Brown scars on bunch stalks or berry stems.
Light Brown Apple Moth (Epiphyas postvittana)
Light Brown Apple Moth (LBAM) is a native Australian leaf– roller. The moths are pale brown with a wing span of about 10mm. Caterpillars are yellow when young and become green with a brown head. Pupae are 10-12mm long and turn from green to brown. Egg masses can be green to yellow-brown.
Look for: Egg masses and small caterpillars every 7-14 days from budburst. Caterpillars inside shoot tips, in leaf rolls, in young bunches and on the underside of mature leaves at flowering and onwards.
Long-tailed Mealybug (Pseudococcus longispinus)
Long-tailed mealybugs have soft bodies covered with a white powdery wax and are fringed by white filaments. Their anal filaments are usually as long as the body.
Look for: Young mealybugs on undersides of basal leaves inside the canopy from late spring; Look for sticky leaves and ant activity in dense canopies or where mealybugs have occurred previously.
Redback Spider (Latrodectus hasselti)
Female redback spiders grow up to 1cm and males 3-4mm. Female redback spiders are black (occasionally brownish) with an obvious red stripe on the upper abdomen. The males red markings are often less distinct.
Look for: Presence of spiders and webs around canopy and bark. During packing special attention must be paid to redback spider to avoid this pest from contaminating the grapes and packing boxes.
Grape Leaf Rust Mite (Calepitrimerus vitis)
Grape leaf rust mites are microscopic (0.2mm long) cream to pink in colour, wormlike and possess two pairs of legs near the head. The most visible and easily recognisable symptoms of rust mite occur from January to March. The vine leaves start to darken and take on a bronzed appearance because of the damage caused by the mites feeding on the leaves. Rust mites overwinter on trunks/cordons then migrate to spurs/canes prior to budburst. They infest newly emerging shoots.
Look for: Bronzed leaves
Black Plague Thrips (Haplothrips froggatti)
Black plague thrips are narrow, dark grey to black in colour and the adults are 2-3mm long. They can be abundant in some years, but rarely cause damage.
Tubular Black Thrips (Haplothrips victoriensis)
Tubular black thrips are 1mm long and their larvae are red. They are predators of two-spotted mite and rust mite on vines in the Sunraysia region.
Look for: Scarred berries
