Abstract

Sex pheromone blends of large black chafer, Holotrichia parallela (Motschulasky), which consist of a major component L-isoleucine methyl ester (LIME) and a minor component (R)-(-)-linalool, showed different attractiveness depending on the mixing ratios of the two components in potato fields in South Korea. The best ratio for H. parallela attraction was 2.5:1 of LIME and (R)-(-)-linalool. The attraction ability of pheromone traps bated with 2.5:1 ratio did not drop up to 14m, but significantly decreased at 21m from H parallela release point. Korean population of H. parallela showed almost same periodical activity to sex pheromone with that reported in Japan, which showing a circabidian periodicity of 48h cycle.

고구마 큰검정풍뎅이 성페로몬 주성분인 L-isoleucine methyl ester (LIME)와 부성분인 (R)-(-)-linalool의 함량비가 2.5:1일 때 가장 큰 유인효과를 나타냈으며, 유인효과가 미치는 거리는 14 m와 21 m의 중간이었다. 한국에 발생하는 큰검정풍뎅이의 성페로몬에 대한 반응은 일본에 발생하는 큰검정풍뎅이와 마찬가지로 48시간 주기를 보이는 것으로 나타났다.
