The grubs of raspberry beetle damage the fruits of raspberry, blackberry and other cane fruits and is the most serious pest of these plants.
Raspberry beetle causes damage in its grub stage, which 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.
