Attractants for the Japanese Pine Sawyer, Monochamus alternatus HOPE (Coleoptera : Cerambycidae)

.BETA.-Myrcene. A potent attractant component of pine wood for the pine wood nematode, Bursaphelenchus xylophilus.

“…1). These compounds were almost the same as those reported in the previous paper, except for their smaller amounts.18) Ikeda et al 19) reported the attractivity of such monoterpenes for the pine sawyer. However, there was no attempt to examine these compounds as attractants for the nematode.…”

Exploitation of kairomones and synomones by Medetera spp. (Diptera: Dolichopodidae), predators of spruce bark beetles

“…The traps were baited with dispensers consisting of a cellulose pad, impregnated with the chemical(s) and sealed within polyethylene foil. The evaporation rate of each chemical is comparable to that associated with injured or attacked Norwegian spruce (Ikeda et al, 1980;Kydonieus & Beroza, 1982;Charlwood et al, 1991;Borg-Karlson et al, 1996;Baier et al, 1999;Pettersson, 2001). The used evaporation rates were (mg/day): -pinene -100; limonene -60; camphor -5; 2-methyl-3-buten-2-ol -100; S-cis-verbenol -5.…”

Spatial Distribution Pattern of Pine Trees Killed by Pine Wilt Disease in a Sparsely Growing, Young Pine Stand

“…The PWNs might leave the beetles and invade rapidly into sound pine trees when the beetles reached new host pine trees, causing new diseased trees there. As the season progresses, the beetles might be attracted to volatiles emitted from dying or newly killed pine trees Ikeda et al, 1980bIkeda et al, , 1981 and aggregate to the colonies with newly diseased pine trees (Shibata, 1986;Togashi, 1989a). As the results, groups of 2009KT might occur in colonies of pine trees other than those with 2008KT.…”
