A study was conducted to find out plant flora, the occurrence of insect pests and natural enemies in the fallow paddy fields of Jeonnam and Jeonbuk provinces from 2004 to 2005. They were identified as 124 plant species in 32 families, 58 insect pest species in 30 families and 11 natural enemy species in 9 families. Plant species belonging to Poaceae and Asteraceae were founded as 28 and 18 species, respectively, and dominated significantly among plants growing in the fallow paddy fields. In insect pests, Conocephalus chinensis, Nysius plebejus, Cletus punctiger, Eysarcoris aeneus, Nephotettix cincticeps, Laodelphax striatellus and Tipula sp. occurred significantly in the fallow paddy fields. Among them, occurrences of N. cincticeps and L. striatellus were low from May to June, and that of L. striatellus was high in August and September. In insect natural enemies, Coenagrion sp., Harmonia axyridis, Propylea japonica and Eristalis tenax occurred significantly in the fallow paddy fields.
