Pheromone traps are a widely-used tool for monitoring pest activity in commercial apple orchards. Studies were conducted to evaluate delta-style traps painted with different colors (orange, red, yellow, green, blue, and white) for capture of obliquebanded leafroller, Choristoneura rosaceana (Harris), and oriental fruit moth, Grapholita molesta (Busck), as well as nontarget muscoid flies (Diptera: Muscidae) and honeybees, Apis mellifera L. An additional study evaluated plastic, four-sided LepTrap® traps of various colors in comparison with a standard delta trap for capture of obliquebanded leafroller, oriental fruit moth, tufted apple bud moth (Platynota idaeusalis (Walker)), and codling moth (Cydia pomonella L.). Capture of obliquebanded leafroller and oriental fruit moth was not significantly affected by trap color. Capture of nontarget flies and honeybees tended to be higher in blue and white (both painted and unpainted) delta-style traps in New York apple orchards, although there was some variability in this response by orchard site. There were no differences in capture of 4 pest species in Pennsylvania between colored, plastic LepTrap® traps and standard unpainted white delta-style traps. Given the observed differences in nontarget capture and the improved efficiencies of finding traps placed within tree canopies, we recommend using yellow, red, or orange delta traps for monitoring of obliquebanded leafroller, oriental fruit moth, and tufted apple bud moth in apple production areas in the eastern United States.

AbstractThe daily pattern of oviposition, the rank order of oviposition preference for three potential hosts, and the effect of experience on oviposition preference were investigated under natural abiotic conditions in the obliquebanded leafroller, Choristoneura rosaceana. Females from the two adult cohorts occurring seasonally oviposited between 0400 and 2400 hours, with peak oviposition around 2000 hours. Both non-choice and choice oviposition trials revealed that the apple and snowberry hosts were preferred over wild rose. Oviposition preference resulted in delays in laying on the less preferred host, but seemed to have no effect on clutch size. Females caged with exclusive access to one of the three hosts appeared to have similar lifetime fecundity or longevity. A first oviposition on wild rose resulted in a delay in laying a second clutch on that host, which suggests the presence of aversive learning that could function to reduce the liklihood of laying successive clutches on a less preferred host. A first oviposition on the apple host, however, seemed to have no effect on further oviposition preference. Hence, it appears that learning would not function specifically to concentrate foraging of the females within apple orchards.
