Abstract

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)-7,11-hexadecadienal (7Z,11Z-16:Al) 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:Al 1mg. Sticky wing trap was more effective than bucket trap. Most caught CLM were attracted at 2$\sim$6 a.m. regardless of season, and activity time of CLM was affected by sunrise time as well as sunset time. The trap catch of CLM was more influenced by wind velocity than temperature for activity time of CLM. The number of caught CLM was fallen at below 13$^{\circ}C$, 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.

귤굴나방, Phyllocnistis citrella Stainton은 운향과(Rutaceae) 특히 감귤류를 가해하는 해충으로 성페로몬 (Z,Z)-7,11-hexadecadienal (7Z,11Z-16:Al)에 대한 귤굴나방의 반응 특성을 조사하였다. 귤굴나방의 포획효율은 7Z,11Z-16:Al을 미끼로 한 끈끈이날개트랩을 이용했을 때 높았다. 귤굴나방이 유인되는 시간대는 일출과 일몰시간이 관여하고 있으며, 그 시간은 오전 2$\sim$6시로 일일 유인수의 93.1%를 차지하였다. 또한 이 시간대의 평균온도와 풍속, 강우가 귤굴나방 트랩 포획에 미치는 영향을 조사한 결과 풍속의 영향이 가장 높았다. 평균온도 13$^{\circ}C$이하에서는 유인수가 감소하였으나 그 이상의 온도에서는 별다른 영향이 없었다. 풍속은 2.0 m/sec 이상일 때에는 유인수가 급격히 줄어드는 경향이었으며, 강우는 별다른 영향이 없었다.
