WEEVILS

Look for in leaves- Chew marks on leaves or on young wood
- Adult weevils at night feeding on leaves
- 'Shot holes' in leaves eaten by various weevils e.g. garden, apple, Fuller's rose, white-fringed and/or black vine weevil
Look for in bunches - Ringbarking of bunch stalks eaten by the garden or apple weevils (Also see Boring Insects and Pests of Young Vines
- Few weevils cause economic damage
- In Western Australia and NZ, weevils sometimes damage small groups of vines. Weevil grubs are like beetle grubs but are small, pale, and have no legs or enlarged rear. Weevil adults usually cannot fly.
- Distinguish weevils from other beetles by their stubby snout, narrow head and shoulders and that they play dead when disturbed. Adults feed at night and shelter under leaf litter or bark during the day.
ACTION **If weevils are of concern, monitor every seven days from budburst till December **At budburst, a spade full of soil near the base of 20 damaged vines may reveal larvae or emerging adults **To monitor for adult weevils, wrap a single-faced corrugated cardboard band (10 cm wide) around the trunk of several vines in spring. After seven days, look for sheltering adults **To find adults during the day, lightly scrape the soil at the base of damaged vines or under leaves and bark on the canopy **During the night, look for weevils eating leaves
