Potato tuber moth pest of potato attacks the tuber both in field and in storage.
They attack potatoes in the field and storage. The larvae mine the young leaves and tunnel into the tubers, leaving frass (faeces and other remains) from tunneling at the entrance.
When the larvae leave the tunnels, fungi, bacteria and mites take over, and tubers rot and have an unpleasant smell.
