    Leafroller: Leafrollers are caterpillars of various moths that gorge themselves on foliage and then pupate within the protection of rolled up leaves making it hard to kill them with any traditional insecticide. Some of the adult moths of the leafroller caterpillars are brown or gray, 1/4 - 1/2 inch long; larvae are dark to light green or cream to yellow, 3/8 - 1- 3/4 inch long. he native North American pest, obliquebanded leafroller, Choristoneura rosaceana (Harris) (Lepidoptera: Tortric-idae), is widely distributed and has a broad range of over 50 hosts, but mem-bers of the Rosa-ceae family are preferred (Sand-erson and Jackson ; Larocque et al. ).

Pandemis leafroller (Pandemis pyrusana). Pest description and crop damage Several species of leafrollers [family: Tortricidae] are pests of tree fruits.

These species use native host plants as well as fruit trees. Pandemis pyrusana and Choristoneura rosaceana are the most commonly found tortricids in commercial orchards in Washington, where the former has increased in importance on apple and cherry in the past 15 years, and the latter is a problem in newly planted apple orchards or in young orchards just beginning to bear fruit.

Information is provided on the recognition, biology, food plants, Cited by: 6. Other leafrollers include the obliquebanded leafroller, Choristoneura rosaceana, and the omnivorous leafroller, Platynota stultana, which are serious problems on fruit trees.

The orange tortrix, Argyrotaenia franciscana, and apple pandemis, Pandemis pyrusana, are pests that occur throughout the year primarily on fruit trees and vines in. Obliquebanded leafroller has two generations per year, overwintering as small larvae in the trees.

The overwintering larvae become active when trees break dormancy, and they complete their development about 3 weeks after the apple blossom period. Adults begin to emerge in late May or early June.

Obliquebanded leafroller is an occasional Pandemis and obliquebanded leafrollers book in spring and summer. Summer damage is most commonly seen in orchards where highly selective codling moth insecticides are used, including mating disruption, that do not control obliquebanded leafrollers.

Leafrollers are among the most destructive lepidopteran pests of tree fruits in Washington, second only to codling moth, Cydia gh a number of leafroller species occurs in Washington, two species,Choristoneura rosaceana (Harris), and Pandemis pyrusana Kearfott, are the most important in commercial orchards.

Lepidoptera: Tortricidae) and obliquebanded leafroller (Choristoneura rosaceana (Harris) Lepidoptera: Tortricidae) held in shaded vials in the tree canopy was measured during the normal flight periods during and In both years all codling moths were dead by degree-days (DD) (21 d) in the spring and DD (8 d) in the by: European leafroller (ELR) and two-generation species (obliquebanded leafroller (OBLR) and threelined leafroller (TLLR).

The distribution and abundance of these leafrollers varies from region to region and within regions, so it is important to know which species are present in your area. Orchard Pest Management provides a practical reference on tree fruit IPM.

Insect hosts, life stages, life histories, damage, monitoring, biological control, and management are described for most major and minor pests in orchards as well as major natural enemies. Obliquebanded leafroller Obliquebanded leafroller larva on a leaf.

25 mm Pheromone traps can be used to determine adult emergence. This information can be combined with growing degree days to predict egg hatch, larval development, and optimal timing for control.

Timing of treatment may depend on the type of insecticide. Moth wings are banded. Mating disruption is currently being used on nearly 75% of the Washington apple and pear acreage (J.F.B., unpublished data), and its success with codling moth fueled the hopes that tortricid leafrollers [obliquebanded leafroller, Choristoneura rosaceana (Harris) and Pandemis leafroller, Pandemis pyrusana Kearfott] attacking apple could be Cited by: Red banded leaf roller and green fruit worm larvae- to distinguish the obliquebanded leafroller from other leafrollers look for dark brown or black head capsules and green bodies.

Insecticide bioassays of the leafrollers, Choristoneura rosaceana (Harris), and Pandemis pyrusana Kearfott (Lepidoptera: Tortricidae), were used to investigate resistance and cross-resistance between azinphosmethyl and other insecticides.
