제주지역에서 굴굴나방, Phyllocnistis citrella (Lepidoptera: Gracillariidae)의 성페로몬, (Z,Z)-7,11-hexadecadienal에 대한 반응


Responses of Citrus Leafminer, Phyllocnistis citrella (Lepidoptera: Gracillariidae) for a Sex Pheromone Component, (Z,Z)-7,11-hexadecadienal on Jeju Island

송정흡, 강상훈


  The citrus leafminer (CLM), Phyllocnistis citrella Stainton, is an oligophagous pest of Rutaceae family, especially Citrus spp. occurring in most worldwide citrus-growing areas. This study was conducted to evaluate a sex pheromone chemical of CLM, (Z,Z)-7,1l-hexadecadienal (7Z,11Z-16:AI) in monitoring CLM by trap types, the diel activity and the influence of some weather factors on trap catch. CLM was well attracted on a trap baited 7Z,11Z-16:AI 1㎎. Sticky wing trap was more effective than bucket trap. Most caught CLM were attracted at 2~6 a.m. regardless of season, and activity time of CLM was affected by sunrise time as well as sunset time. The trap catch of CLM was more influenced by wind velocity than temperature for activity time of CLM. The number of caught CLM was fallen at below 13℃, but there was little effect for trap catch at over that temperature. The average wind velocity at over 2.0 m/sec made the number of caught CLM drop down. The precipitation did not affect the number of caught CLM when the average wind velocity was lower than at 2.0 m/sec.
