Avoidance of nonhost plants by a bark beetle, Pityogenes bidentatus , in a forest of odors

Naturwissenschaften, 2004
The bark beetle, Pityogenes bidentatus (Coleoptera: Scolytidae), searches in mixed conifer and deciduous forests of northern Europe for suitable branches of its host, Scots pine ( Pinus sylvestris). We tested whether odors from several diverse nonhost trees and plants common in the habitat (e.g., mountain ash, Sorbus aucuparia; oak, Quercus robur ...

Strategies of a bark beetle, Pityogenes bidentatus , in an olfactory landscape

Naturwissenschaften, 2000
Volatiles from leaves or bark of nonhost birch (Betula pendula) and Norway spruce (Picea abies) dramatically reduced the attraction of the bark beetle, Pityogenes bidentatus (Coleoptera: Scolytidae), to their aggregation pheromone components (cis-verbenol and grandisol) in the field.

Aggregation pheromones of bark beetles, Pityogenes quadridens and P. bidentatus, colonizing Scotch pine: olfactory avoidance of interspecific mating and competition

Chemoecology, 2013
The bark beetles Pityogenes bidentatus and Pityogenes quadridens (Coleoptera, Curculionidae, Scolytinae) are sibling species that feed and reproduce in bark areas on branches of Scotch pine, Pinus sylvestris. To identify aggregation pheromone components of both species, hindguts and head/thoraxes of males and females of both species feeding in hosts ...

Associations between Pityogenes bidentatus and fungi in young managed Scots pine stands in Poland

Forest Pathology, 2008
SummaryThe association between Pityogenes bidentatus and fungi was studied in young, managed Pinus sylvestris stands in Poland. Fungi were isolated from emerged adults and their galleries collected from four populations. In total, 2089 fungal isolates including 42 species, were obtained. Penicillium sp. 1 and Geosmithia sp.

Inhibitory Effect of Monoterpenes on Response of Pityogenes bidentatus to Aggregation Pheromone Released by Piezoelectric Sprayer for Precision Release of Semiochemicals

Journal of Chemical Ecology, 2000
A piezoelectric sprayer for dispensing semiochemicals was developed and used for a field test of bark beetle semiochemicals. The sprayer consists of a geared pump that pushes a syringe slowly to dispense semiochemicals in solvents through a microtube to a glass micropipet fixed to a piezoelectric high-frequency vibrator. The frequency is adjusted via a
