Insect and natural enemy fauna were surveyed at conventional (CV) and organic-farming persimmon orchards (OF) at Jinju, Korea, using sweeping net and naked eyes in 2013 and 2014. Using sweeping net, 49 species at an OF and 18 species at a CV were observed in 2013. In 2014 too, more species were observed at OF (66 species, 33 families, 7 orders) than at a CV (25 species, 15 families, 5 orders). During both the years, dominant species were all hemipteran insects like Nysius plebejus (Lygaeidae) and Cletus punctiger (Coreidae) in both types of orchards, followed by Rhopalus maculatus (Rhopalidae), Riptortus pedestris (Alydidae). Similarly, naked eye inspection also found more species at OF (192 species, 72 families, 11 orders) than at CV (104 species, 52 families, 10 orders) in 2014. Dominant species in naked eye inspection were Lycorma emelianovi (Hemiptera: Fulgoridae), Apis mellifera (Hymenoptera: Apidae), Uroleucon cephalonopli (Hemiptera: Aphididae) at OF, and A. mellifera and R. maculatus at CV in 2014. Using naked eye inspection or sweeping net in 2014, more species of natural enemies were observed at OF (31 and 9 species, respectively) than at CV (18 and 5 species, respectively).
