A total of 164 cases with Hymenoptera stings have been treated in our hospital during the 3 year period from 2002 to 2004. We examined year-on-year incidence of the insect stings, monthly distribution, occurrence time, elapsed time from occurrence to visit to our hospital, age, male-female ratio, stung parts, number of stings, types of Hymenoptera, symptoms, and the rate of emergency room visits. The largest number of 83 cases were treated during 2004. A great number of cases were observed from June to September. The stings most frequently occurred during the daytime, and 95 males (58%) and 69 females (42%) were treated. Many of them were in their 50s years or above. The parts which the insect attack were mostly exposed parts such as hands, the upper limbs, face, and legs. Seven cases had systemic reactions (4%), one had urticaria, one had palpitations, two had nausea, two felt ill, and one suffered a anaphylactic shock. The most of the victims were elderly people engaged in agriculture in this area. The stings were most frequently observed in 2004, because there was less precipitation from May to June in that year. The propagation of Hymenoptera became active when the rainfall decreased.
