Abstract
Many moth pheromones and synthetic attractants have been used to monitor or decrease pest populations However due to their low economic efficiencies and narrow target specificities these methods are of limited use for trapping pests in large agricultural fields In an effort to address this problem we selected oak Quercus serrata sawdust media fermented by the yeast strain Pichia anomala and examined its ability to attract lepidopteran moth pests for mass trapping in an apple Malus domestica orchard A total of 57 taxa were trapped including 42 species of lepidopteran pests The most frequently caught lepidopteran pests included Adoxophyes orana 400 ± 35 individuals/trap/week Oraesia excavata 355 ± 25 and Adris tyrannus amurensis 355 ± 25 Notably less fruit damage was recorded in the experimental orchard versus a trapfree neighboring control orchard These results suggest that adult moths might be effectively attracted and mass captured using P anomalafermented oak sawdust media as bait
