In 2017, a total of 82 non-target species representing six orders of insects were captured in four types of tephritid fruit fly (Diptera: Tephritidae) surveillance traps located in Korea; the species included 6 families of Coleoptera, 1 of Dictyoptera, 17 of Diptera, 2 of Hemiptera, 3 of Hymenoptera, 1 of Neuroptera, 4 of Lepidoptera, and 1 of Raphidioptera. Of these, Diptera were the most abundant; the main families included Muscidae, Tephritidae, and Anthomyiidae. Herein, based on a survey, we present a list of the species of non-target insects captured in the tephritid fruit fly surveillance traps.
