Redbanded leafroller

Argyrotaenia velutinana (Walker)
Lepidoptera: Tortricidae

The adult's forewings are grayish brown with a subtle dark red and brown oblique band (A). The larva is pale green with a yellow or green head (B).

Distribution

Most fruit-growing states and provinces in eastern North America.

Damage

Attacks apple mainly; other fruit trees may be affected. Larvae cause rolling of the leaves; they feed on the surface of fruit (C) and dig superficial tunnels in the flesh of fruit. Damage can be confused with that of the lesser appleworm (Grapholita prunivora), but in the case of the redbanded leafroller, damage is not accompanied by reddish frass.

Similar Species

Resembles other tortricid larvae, but most, including obliquebanded leafroller (Choristoneura rosaceana), fruittree leafroller (Archips argyrospila) and threelined leafroller (Pandemis limitata) are larger and have a darker head.

Management

This insect may become problematic in orchards under a softer pesticide program or those relying on mating disruption for other species. Species presence and flight activity can be monitored with pheromone traps. Economic infestations can be controlled by the use of selective (e.g., Bacillus thuringiensis) or broad-spectrum insecticides.
