“…By the mid-1970s, obliquebanded leafrollers were causing "some significant fruit damage" to apple plantings despite multiple insecticide applications (Reissig 1978). During the 1980s, oblique banded leafrollers became a more serious pest and a phenological model was developed to allow better timing of insecticide applications (Onstad et al 1985). At the same time, Reissig et al (1986) documented that this pest was becoming resistant to insecticides.…”

Effect of atmospheric permeation with synthetic sex pheromone on the behavior lmd control of oblique banded leafroller, Choristoneura rosaceana (Harris), was studied in small and large plots in commercial apple orchards. Synthetic sex pheromone significantly reduced the ability of male moths to locate pheromone-baited traps and tethered females; however, no differences were found among 3 pheromone rates. Location of pheromone dispensers within the tree canopy did not alter the number of males locating pheromone-baited traps and mating tethered females. Oblique banded leafroller activity was greatest in the upper positions of the tree canopy and no edge effect was observed around perimeters of large dismpted blocks. The presence of gravid feral females, mated tethered females, high larval densities, and fruit damage within large pheromone dismpted blocks indicate obliqubanded leafrollers mate in orchards treated with synthetic sex pheromone. However, fruit damage caused by obliquebanded leafroller larvae was similar in pheromone, pheromone plus insecticide, and insecticide treatments.

“…there ii a considerable range of developmental stages occurring at any particular time in the field during the summer generation (Onstad et al 1985;Gangavalli and Aliniazee 1985). Therefore, number of degree-days was related to pest phenology by using data from Onstad et al (1985,1986) and Gangavalli and Aliniazee (1985) to determine when the majority of larvae were in a particular stage.…”

Abstract-The rate at which obliquebanded leafroller, Choristoneura rosaceana (Harris), larvae vacated feeding sites in apple, Malus dornestica Borkhauser (Rosaceae), trees was determined by monitoring infested terminal foliage under field conditions. The overwintering and summer generations of C . rosaceana were monitored in two orchards in 1997 and 1998. Larvae vacated terminal feeding sites relatively frequently because 50% of the sites during the overwintering and summer generations were vacant 34 f 6"d (threshold = 6°C) and 53 f 10°d, respectively, after sites had been marked. Vacancy rates increased from the beginning to the end of the summer generation in 1997 but remained relatively constant throughout the summer generation in 1998. The differences between the 2 years were probably because of less precipitation and lower availability of actively growing tirminal foliage at the end of the summer in 1997 than in 1998. Differences in larval development did not seem to contribute to differences in vacancy rate. Recolonization of growing terminals was also studied in the field by removing C. rosaceana larvae from terminals only (1997) and the entire tree (1998). In 1997 and 1998, larval recolonization of terminals and trees occurred, because 6-8 d after larvae were removed populations in removal and adjacent control trees were not significantly different. Frequent larval movement to actively growing terminal foliage with sublethal insecticide residues may increase larval survival and could slow resistance development by providing a refuge for susceptible insects.Waldstein DE, Reissig WH, Nyrop JP. 2001.

“…Fruit damage may occur if insecticides are applied too late. Because the hatch period for obliquebanded leafroller larvae lasts between 3 and 4 wk (Onstad et al 1985), and insecticides are usually applied at 2-wk intervals, repeat applications after the initial spray are often necessary. Late applications of insecticides against larger larvae may be less effective, because late instars may be less susceptible than neonates to some orchard insecticides (Reissig 1978, Biddinger et al 1998.…”

“…Reissig (1978) examined the relationship between obliquebanded leafroller egg development and temperature more thoroughly. Onstad et al (1985) developed a model that related the entire life cycle of the obliquebanded leafroller to the number of degree-days accumulated after the Þrst moth catch. The results of this study indicate that egg mass hatch begins 168 Ϯ 7 degree-days base 6ЊC (DD 6 ) and ends at Ϸ550 DD 6 .…”
