The grubs of raspberry beetle can damage the fruits of raspberry, blackberry and other cane fruits.

Raspberry beetle affects fruit in the larval stage. The larva feeds at the stalk end of the fruits. It is mainly a problem on summer-fruiting raspberries. Early fruits on autumn raspberries may be damaged, but those ripening after late August are less likely to be affected.
A host plant odour (karimone) water trap is available from Agralan, Ken Muir, Harrod Horticultural and some other suppliers. This will trap both male and female beetles which may help reduce infestation levels.
