Raspberry beetle on raspberry plants.

The raspberry beetle (Byturus tormentosus) can be a serious pest of cane fruit such as raspberries, blackberries and loganberries. Damage is caused by the adults feeding on the leaves and flowers as well as larvae feeding on the fruit.

Fortunately, they can be controlled without pesticides and we now supply Raspberry Beetle Traps in our range. If you do intend to use an insecticide, the traps can also be used as a way of detecting the best time to spray.

The raspberry beetles emerge from the soil from April to June and are attracted to flowers using sight and smell. A female adult can lay over 100 eggs in the fruit which hatch into pale brown larvae and can be difficult to spot causing the fruit to appear smaller and shriveled if they develop at all. Larvae contaminate and damage fruit and fungi can also cause blemishes. Once fully grown, the larvae drop to the ground and pupate in the soil below the host plant.

This pest damages both wild and cultivated raspberries and blackberries.

Our natural trap allows you to detect signs of the beetle, then catch without pesticides once they emerge in the spring. The attractant lure is irresistible to the beetles, trapping them and removing the danger to your plants.

The trap is best used as beetles emerge before the first flowers appear between April-June. For later flowering berries, a second lure can be used. Each lure will last for 6 weeks.
