Abstract

Striped flea beetle, Phyllotreta striolata (SFB) and turnip sawfly, Athalia rosae ruficornis (TSF) are two economically important sporadic pests in radish fields on Jeju island. The response of adult SFB and TSF to a mixture of aggregation pheromone, (+)-(6R,7S)-himachala-9,11-diene and host plant volatile, allyl isothiocyanate (HAI), as well as to yellow and blue sticky traps was examined in radish fields. Adult SFB was more attracted to the sticky trap with HAI, regardless of the color of the sticky trap; however, adult TSF was more attracted on the yellow sticky trap than blue, and no effect of HAI was observed. The adult SFB and TSF can be effectively monitored using yellow sticky traps placed 10 cm above the plant canopy. SFB and TSF had 3 and 5 peak times in a year, respectively. The first peak occurred in the middle of March for SFB and mid-late of April for TSF. We expect that the results of the present study can facilitate minimizing the damage caused by the two important pests in commercial radish fields.

벼룩잎벌레(Phyllotreta striolata)와 무잎벌(Athalia rosae ruficornis)는 제주지역 무에서 돌발적으로 발생하여 피해를 주는 해충이다. 본 연구는 벼룩잎벌레와 무잎벌 성충의 트랩 색(황색과 청색)과 벼룩잎벌레 집합페로몬(+)-(6R,7S)-himachala-9,11-diene과 기주식물 휘발성 물질인 allyl isothiocyanate의 혼합물을 이용 두 해충의 발생을 간편하게 예찰하는 방법을 개발하기 위하여 수행하였다. 벼룩잎벌레는 트랩 색에 관계없이 집합페로몬이 부착된 점착트랩에 더 많은 성충이 유인되었으며, 무잎벌은 황색점착트랩이 청색트랩보다 더 많이 유인되었고 벼룩잎벌레 집합페로몬은 유인량에 관계가 없었다. 따라서 벼룩잎벌레 집합페로몬을 부착한 황색점착트랩을 이용하면 벼룩잎벌레와 무잎벌 성충 발생을 효율적으로 예찰할 수 있었다. 점착트랩의 높이는 기주식물에 가까울수록 두 해충의 유인수가 많아 기주식물 상단 10 cm 높이로 설치하는 것이 좋을 것으로 판단되었다. 벼룩잎벌레와 무잎벌의 연간 발생피크는 각각 3회와 5회정도 나타났으며, 두 해충의 첫 주발생시기는 벼룩잎벌레는 3월중하순, 무잎벌은 4월 중하순이었다. 벼룩잎벌레와 무잎벌 성충의 연간 발생특성을 이용하면 두 해충의 무에서의 피해를 최소화하는데 중요한 정보로 활용될 것으로 기대된다.
