Anarsia lineatella

Short pest overview:

It is a moth of the family Gelechiidae. It is commonly found in Europe, Asia, and North America. The wingspan is 11-14 mm. The moths are on wing from June to August depending on the location.

Geographic Distribution:

This moth is present in Europe, Asia and North America.

Life Cycle:

The pest usually has four annual generations, beginning in April-May. Larvae (caterpillars) of the overwintering generation initially enter the flowers and buds, and then the twigs, boring mines and killing the buds and twigs. When twig tissue hardens in summer the pest moves into fruits, their damage increasing later in the season. The overwintering second or third instar larvae hide in bark crevices, in silken chambers, excavated in the inner bark of branches or twigs.
