[Prior Art and Problems to be Solved by the Invention]

The larvae of the scarab beetle, Scarabaeidae, has recently caused a large outbreak in southern Japan and the Kanto region, especially in Chiba and Ibaraki prefectures, and has caused serious damage to turfgrass and the like on golf courses.

[0005] It is very difficult to prevent or control the damage caused by the Japanese red velvet, depending on the conventional insecticide.

Generally, in order to effectively control pests, an attractant is added to a predictive means for accurately knowing the occurrence thereof or a new type of control means different from the conventional control means using insecticides. Is being used,

Conventionally, as an attractant for scarab beetles, LIME (L-isoleucine methyl este), which is the main component of the sex pheromone of Holotrichia parallera, has been used.

However, the attractant by LIME is
It could not be said that it had a sufficient attracting effect on the Japanese flounder.

[0009] Therefore, there has been a demand for an attractant having a sufficient attracting effect on the Japanese pearl hemlock beetle.

[0010] The chemical structure of the sex pheromone of Pleurotus cornucopia has already been confirmed by Real et al.
(-)-(Oct-1-enyl) oxacyclopentan-2-one and (R, Z) -5-(-)-(dec-
It has been clarified that it is 1-enyl) oxacyclopentan-2-one (Annual Meeting of the Inte
rnational Society of Chemical Ecology, Clearwater
July 31- Aug. 4, 93).

[0012] However, it is desired to develop a more effective method for investigating an effective developmental surveillance of H. albicans and a method for catching a large number of adults, as compared with the case where the sex pheromone of A. albicans is used alone. It was rare.

[0012] Therefore, there has been a demand for an attractant having a stronger attracting effect than the case where the sex pheromone is used alone, against the green leaf beetle.
