Influence of Trap Colour on the Capture of Codling Moth (Lepidoptera: Tortricidae), Honeybees, and Non-target Flies

摘要

Studies were conducted to evaluate the influence of trap colour on the captures of honeybees, Apis mellifera L., codling moth, Cydia pomonelia L., and non target muscoid flies in sticky delta traps. Traps varied widely in their spectral reflectance. The unpainted white and the painted white and cream traps had the highest reflectance. The painted green trap had the lowest total reflectance. The green, orange, and red traps had low reflectance at wavelengths < 560 nm. Red and green painted traps consistently caught the fewest honeybees, while the unpainted white trap caught the most. Red painted traps caught the greatest number of flies. Significantly more codling moths were caught in green and orange versus the unpainted white traps, in a later experiment, painted green traps caught more codling moths than unpainted white traps.
