ABSTRACT

Simple Summary The Indian meal moth, Plodia interpunctella (Hübner, 1813) (Lepidoptera: Pyralidae), exhibited significant differences in oviposition preference between normal-oleic peanuts (NOPs) and high-oleic peanuts (HOPs). In this study, we found key volatile organic compounds (VOCs) from NOP and HOP peanuts that were attractive or repellent to P. interpunctella females by gas chromatography/mass spectrometry (GC-MS), gas chromatography/electroantennographic detection (GC-EAD), and electroantennogram (EAG) analysis, as well as behavioral responses in Y-tube olfactometer and wind tunnel bioassays. The identification of key VOCs may provide a foundation for developing food-based attractants and repellents for pest control.
