Small gooseberry sawfly

The small gooseberry sawfly (lat. Pristiphora rufipes) is a member of the order Hymenoptera, family Tenthredinidae. This pest is a significant threat to berry crops, particularly in temperate regions where it can cause severe foliage loss within a short timeframe.

The primary hosts for this insect are gooseberries, although it also frequently attacks white and red currants. The larvae are the stage responsible for the damage, as they feed on the leaves, leading to decreased plant vigor and reduced fruit production if left unchecked.

The life cycle involves overwintering as fully grown larvae within silken cocoons in the soil beneath the host plants. In early spring, they pupate, and the adult sawflies emerge to mate and lay eggs. The eggs are typically deposited on the underside of leaves, usually near the veins for protection.

Damage symptoms begin as small, irregular holes in the foliage created by young larvae. As the larvae mature, they consume the entire leaf surface, leaving only the primary veins intact (skeletonization). A heavy infestation can lead to complete defoliation, which severely stresses the plant and inhibits growth.

Control strategies require a combination of cultural and chemical methods. Cultural practices, such as clearing debris from beneath bushes and disturbing the soil, can reduce the number of overwintering cocoons. If chemical control is necessary, apply registered insecticides during the early larval stages when they are most vulnerable to treatment.

• Manual removal of infested leaves in early stages.
• Cultivation of soil around the base to disrupt pupation.
• Monitoring for adult activity using sticky traps.
• Timely application of targeted insecticidal sprays.
