초록

본 시험은 온도 발육모델을 이용하여 꽃매미 알의 부화시기를 예측하고 약충과 성충 방제에 효과적인 친환경 자재선발 및 끈끈이트랩 색상별 유인효과를 찾기 위하여 수행하였다. 꽃매미 알은 15, 20, $25^{\circ}C$(14L:10D)에서 각각 55.9, 26.8, 21.6일 만에 부화하였고 부화율은 각각 61.9, 57.8, 30.4%로 온도가 높을수록 부화소요기간은 짧고 부화율은 낮았다. 알의 온도와 발육속도와의 관계식은 Y=0.0028X-0.0228 ($R^2$=0.9561)이었으며, 발육영점온도는 $8.14^{\circ}C$, 유효적산온도는 355.4일도였다. 위의 관계식에 의하여 전남지역 꽃매미 알의 부화시기는 5월 22일로 예측되었다. 꽃매미 약충방제에 효과적인 친환경자재는 제충국추출물, 고삼추출물, 데리스추출물이었고, 성충은 제충국추출물, 고삼추출물이었다. 황토색, 파랑색, 노랑색 끈끈이트랩 중에서 황토색끈끈이트랩의 유인량은 2주 동안에 약충 535마리, 성충 87.7마리였다. 황토색 끈끈이트랩은 꽃매미 약충과 성충의 유인포살효과가 우수하였다.

This study was conducted to predict the hatching time of eggs of Lycorma delicatula, to select an effective environmentally-friendly agriculture material (EFAM) and to evaluate the attraction effect of brown sticky traps for controling of Lycorma delicatula nymph and adults. Eggs hatched 55.9, 26.8, 21.6 days after incubation at 15, 20, $25^{\circ}C$ with 14L:10D condition and the hatching rates of egg were 61.9, 57.8, 30.4%, respectively. At high temperature conditions, egg development periods were shorter and the hatching rate was lower. The relationship between temperature and developmental rate was expressed by the linear equation Y=0.0028X-0.0228, $R^2$=0.9561. The low temperature threshold of eggs was $8.14^{\circ}C$ and the thermal constant required to reach larva was 355.4 DD. According to this relationship, the mean estimated hatching date was $22^{nd}$ May. The effective EFAM was natural plant extract, sophora extract, derris extract to nymph and natural plant extract, pyrethrum extract, sophora extract to adult. Among three colors of sticky trap : brown, blue and yellow, the brown sticky trap was the most attractive to nymphs and adults of L. delicatula over a 2 weeks trial period. It suggested that the brown sticky trap could be a very useful and environment-friendly control method for nymphs and adults of L. delicatula.
