Abstract

The seasonal occurrence trends of the brown-winged green bug, Plautia stali, and the brown malmorated stink bug, Halyomorpha halys, were monitored in sweet persimmon orchards in southern region of Korea using light traps (in 2000 and 2001), and aggregation pheromone traps (methyl (E, E, Z)-2 ,4, 6-decatrienoate)) of P. stali (in 2001). Light trap data showed that H. halys started to occur from the end of June, and reached its peak in early or mid August, while P. stali was mostly attracted to the traps from mid July to late August without any distinct attraction peak. Both species did not occur after September in the persimmon orchards studied. The attraction patterns of both species to aggregation pheromone traps were different from those observed in light traps. Both species were attracted to the pheromone traps from mid May to late August. The peak occurrence of H. halys could not be detected due to low catches. However, the period of peak attraction for P. stali was from late June to late August depending on the geographical locations. The aggregation pheromone traps of P. stali attracted more number of P stali than H. hails, but the light traps showed a reverse pattern. In both species, more females were attracted to the aggregation pheromone traps than males. The difference of attraction patterns between 2 types of traps was discussed in relation to content of soluble tannin in persimmon fruits.

경남 지역의 단감원에서 2000­2001년에 수은유아등과 2001년에 갈색날개노린재의 집합페로몬(methyl (E, E, Z)-2, 4, 6-decatrienoate)) 트랩을 이용하여 갈색날개노린재(Plautia stali)와 썩덩나무노린재(Halyomorpha halys)의 발생소장을 조사하였다. 유아등 조사결과 썩덩나무노린재는 6월 하순부터 발생하기 시작하여 8월 상ㆍ중순이 최성기이었다. 갈색날개노린재는 썩덩나무노린재와는 달리 유살 최성기가 뚜렷하지 않았는데, 主 유인시기는 2개년 모두 7월 중순­8월 하순이었다. 두 종 모두 9월 이후에는 거의 유살되지 않았다. 집합페로몬 트랩에 의한 유살 양상은 유아등에 의한 유살양상과 달랐다. 집합페로몬 트랩조사 결과, 두 종 모두 5월 중순부터 8월 하순까지 꾸준히 유인되었다. 썩덩나무노린재는 유인수가 적어 주 발생시기가 뚜렷하지 않았고, 갈색날개노린재는 지역에 따라 6월 하순부터 8월 하순 사이에 많이 유살되었다. 갈색날개노린재는 수은유아등 보다는 집합페로몬 트랩에, 썩덩나무노린재는 수은유아등에 더 많이 유인되었다. 또한 집합페로몬 트랩에는 두 종 모두 수컷보다 암컷이 더 많이 유인되었다. 두 종류의 트랩에 의한 유살소장 차이의 원인을 탄닌함량과 연관지어 고찰하였다.
