Acrolepiopsis assectella (Zeller) - (leek moth)
This small moth is native to Europe with some records in Asian countries. It has been accidentally introduced into North America and was first recorded in Canada in 1993. Since 2009 it is also found in the north-eastern U.S. It is an important pest of Allium crops.
The larvae initially mine the leaves and at a later stage bore into the centre of the plants feeding on the stem or the bulb. The damage on the leaves (leek) or bulbs (onions) can make the crop unmarketable. There are 2 to 5 generations per year with the adults overwintering.
