Spodoptera exigua Hiibner and Spodoptera litura Fabricius occurred onall vegetables. Additionally, Frankliniella interna Trybom, Trialeurodes vaporariorum Westwood, Myzuspersicae Sulzer, and Phytomyza horticola Goureau occurred on all vegetables except Liliaceae(4///wm tuberosum Rottl. and Allium fistulosum L.). Thirteenspecies of insect pests including Hymenia recurvalis Fabricius occurred only one vegetables, indicating that they were monophagous. The main insect pests of Chenophodiaceae were M. persicae, H. recurvalis, S. exigua and S. litura whereas Dolycoris baccarum Linne, Trialeurodes vaporariorum Westwood, Trichoplusia ni Hiibner, and P. horticola were not recorded. On Brassicaceae were Brevicoyne brassicae Linne, M. persicae, Phaedon brassicae Baly, Phyllotreta striolata Fabricius, Plutella xylostella Linne, Hellula undalis Fabricius, 5". litura, Pieris rapae Linne, Artogeia rapae Linne, mdAthalia rosae ruficomis Jakovlev, but six species including Frankliniella intonsa Trybom were not recorded, The degree of damage by insect pests on Apiaceae was low, five species including Tetranychus kanzawai kishida, F. intonsa, T. vaporariorum, S. litura, and P. horticola were not recorded. The main insect pests on Liliaceae were Thyatira tabaci Lindeman, Acrolepiopsis sapporensis Matsumura, S. exigua, and Liriomyza chinensis Kato. The damage to Compositae by insect pests was relatively low except that of S. litura.
