Argyrotaenia franciscana Walsingham

Description

Argyrotaenia franciscana (Walsingham) (Tortricidae: Tortricinae)

The orange tortrix, Argyrotaenia franciscana, is a polyphagous species that is an occasional pest of avocado in California. This species is found primarily in cooler coastal areas and river valleys, where adults may be present year round; only two generations are present in warmer inland areas (Powell 1964). Larvae feed in silken shelters on outer shoots and can cause economic damage by chewing holes in fruit and even causing fruit to drop by feeding on the stem (Faber et al. 2010).
