“…Flying SBB were trapped during the months of May, June and July, 1986. Four Borregaard drain-pipe traps were deployed every 150 m along the margin of the 1981 blowdown area in the Tokyo University Forest in Furano, Hokkaido, Japan (FURUTA et al, 1985). Each trap contained a dispenser containing 1500 mg methylbutenol, 70 mg cis-verbenol and 15 mg ipsdienol.…”

“…In 1981, typhoon number 15 extensively damaged forests in the northern Japanese island of Hokkaido, precipitating a buildup of SBB populations in stands of (FURUTA et al, 1985). This event enabled us to collect SBB and compile a list of the Japanese phoretic mite species and their hyperphoretic fungal ascospores, and compare these with those collected from Europe.…”

Flying Ips typogruphus juporzicus from Hokkaido (Japan) carried 12 species of phoretic mites, three of which were not previously recorded in Europe. The mite biologies were diverse, including specialists feeding on microorganisms, beetle eggs, and nematodes which were common under beetle elytra. Hyperphoretic on these mites were seven distinct species of fungal spores, plus an undetermined number identifiable only as conidia. The spores stuck anywhere on the mite bodies with no special carrying structures evident. Ophiostomu hicolor was the most common species, with the pathogenic Cerutocystis polonicum present in small numbers.

“…Uncollected windthrown trees provide important breeding material for bark beetles (Coleoptera: Scolytidae) and, thus, wind damage in forests often results in a serious risk of bark beetle outbreaks (e.g. Furuta et al 1984, Långströ m 1984, Reynolds & Holsten 1994.…”

Windthrows and Dead-standing Trees as Bark Beetle Breeding Material at Forest-clearcut Edge

The spatial distribution of windthrows and dead-standing trees as well as the occurrence of two bark beetle species, Ips typographus and Tomicus piniperda, were studied at forest-clearcut edges in southern Finland. More than 80% of the recorded dead trees were situated within the first 15 m from the clearcut border. The number of dead-standing spruces attacked by I. typographus did not depend on the amount of windthrows at the same site. According to logistic regression analysis, the distance from a clearcut border had a negative effect on the likelihood of I. typographus being present in the windthrows. The results indicate that windthrows do not necessarily increase bark beetle-induced tree mortality under endemic wind conditions. The accumulation of dead trees at forest-clearcut edges may support the diversity of saproxylic species, but may also maintain populations of harmful bark beetles under non-epidemic conditions.

“…Trapping of spruce beetles in this study was originally planned to ascertain the disturbing effects of the anti-aggregation pheromone 'ipsenol' on aggregation-pheromone trap catches. However, ipsenol did not show any effectiveness in reducing the number of beetles caught in traps when it was placed more than several meters away from the traps (FURUTA et al, 1994). Therefore, in this paper we use this trapping data for the analysis of the abundance of spruce beetles inside and outside the forest.…”

Seasonal difference in the abundance of the spruce beetle (Ips typographus japonicus Niijima) (Col., Scolytidae) within and outside forest in a bivoltine area

In Hokkaido (Japan), the spruce beetle (Ips typograpaus japonicus) kills standing spruce trees after selection cutting. The seasonal change in the number of beetles captured in 18–21 traps within or outside forest was analysed, with reference to a control strategy for this species in a bivoltine area. The number of beetles captured in traps had two peaks: one, which was small, in early June, and the other, which was a large peak, in July. However, the number of beetles captured in traps outside the forest had only one small peak, in June. The difference between the inside and outside of the forest was caused by the difference in the number of newly emerged beetles captured in traps. Beetles were distributed contagiously within the forest and there was no remarkable change in distribution pattern throughout seasons. Beetles were distributed at random in June when beetle activity was high outside forest. Overwintered beetles must undertake long‐range dispersal irrespective of whether they are within or outside of forest for finding suitable breeding materials. Nevertheless, the most important point is that newly emerged beetles stayed inside the forest and only a few individuals dispersed outside the forest. This study recommends that different control methods are adopted according to the seasons for the control of spruce beetles.
