Nymphs are pale green in colour. They feed on the underside of leaves. First feeding damage looks like small, pin-point yellow spots on the upper surface. Crawlers hatch over an extended period of time. Treat once hatch is observed and follow with a second treatment as required.
Systemic insecticides are more effective.
Hooked and crooked candles on mugo and scots pine can be the result of the feeding of European pine shoot moth. Damaged shoots can be pruned out to remove larvae. Delay chemical control until adults have emerged and new larvae hatch, in early July. Click here for a list of all agriphone numbers.
