“…4). This may indicate that female antennae contain more receptor cells that respond to this compound, supporting the data obtained by single-cell activity recordings that showed that females contain a higher proportion of receptor neurones tuned for compounds of host-plant origin than do males (Andersson et al 2009). I. typographus attacks many more spruce trees than those that become successfully colonised and subsequently killed (e.g.…”

“…Ips typographus can perceive at least 18 compounds emitted by its host plant (Kalinová et al 2014). Electrophysiological recordings from individual olfactory sensilla on I. typographus antennae indicate that approximately 42 % of olfactory receptor neuron cells are specialised for pheromone perception, 35 % for perceiving host-plant compounds, and at least 23 % for detecting non-host-plant compounds (Andersson et al 2009). Behavioural assays have demonstrated that several non-host compounds can inhibit I. typographus beetle attraction to the pheromone (Zhang et al 1999;Zhang and Schlyter 2003).…”

“…Some volatile plant secondary metabolites sensed by bark beetles remain unknown, as proved by electrophysiological analysis of beetle receptor neurons in olfactory sensilla: it is still not known what substances approximately 24 % of receptor cells respond to (Andersson et al 2009). Ips typographus preferentially infest old (over 100 years) and large (Becker and Schröter 2000;Zolubas et al 2009) spruce trees.…”

Abstract& Key message Spruce trees emit significant amounts of trans-4-thujanol, but the amount of this compound in bark decreases with tree age. Trans-4-thujanol acts as an efficient repellent for the bark beetle Ips typographus. & Context The spruce bark beetle, Ips typographus, is an economically significant pest of Norway spruce (Picea abies) that preferentially infests and kills old trees. & Aims We looked for spruce volatiles that were perceivable by I. typographus and that differed as the host tree aged. & Methods Bark beetles were collected in the wild. Bark samples from spruce trees of different age were hydrodistilled. Gas chromatography-electroantennogram detection (GC-EAD) was used to identify which compounds induced beetle olfactory responses. These were identified by gas chromatography-mass spectrometry (GC-MS). Behavioural responses of bark beetles were tested using a Y-tube olfactometer. & Results Several EAD peaks were recorded, of which trans-4-thujanol was consistently active and could be identified chemically unequivocally. The antennae of I. typographus females responded to a lower dosage of the compound than males, but both sexes were repelled by it. The bark of 10-year-old spruce trees contained 3 times more trans-4-thujanol than that of 35-40-year-old trees, 27 times more than that of 70-to 80-year-old trees, and 200 times more than that of 120-year-old trees. & Conclusions Trans-4-thujanol is a bioactive compound in Norway spruce bark that varies in amount with tree age and affects spruce bark beetle behaviour under laboratory conditions. It is suggested that trans-4-thujanol might play a role in both spruce tree defence and tree choice by beetles.

Abstract• The effect of water stress on host selection and performance during the shoot feeding phase, by the Mediterranean pine shoot beetle Tomicus destruens, was studied.• Young potted Pinus pinaster plants were subjected to two water supply regimes: (i) well watered; (ii) 4-5 months of moderate drought stress. Plant volatile organic compound (VOCs) emissions were collected by SPME and analysed by GC/MS.• In tests with paired plants, the number of holes and tunnels excavated by beetles in well watered pines was significantly larger than in stressed plants, whereas in no-choice tests no differences occurred.• Beetle survival was significantly higher on well watered, than on stressed pines (p = 0.006), while fat contents also increased (p = 0.09).• Plants could be assigned to treatments based on VOCs emissions, stressed pines emitting more myrcene and less β-pinene than well watered ones.• It is concluded that during the shoot feeding phase, T. destruens preferentially attacks non-stressed plants, in detriment of stressed ones, upon which a higher fitness is attained.• The role of pines VOCs emissions under moderate drought stress, in the host selection and colonization process by the pine shoot beetle, is discussed.

“…The whole sequence of mechanisms is still unclear, in particular about host location and attack (habitat location, host location, host acceptance, overcoming of defenses). Interestingly, while no "primary attraction" sensu strictu (Anderson 1948) has been proven, the sensory array of I. typographus includes many receptors for host monoterpenes (Andersson et al 2009, Andersson et al 2010. The defense at tree and stand scales may be explained by water stress (project Kyrill).…”

In natural spruce stands, a change of generation is usually initiated by wind or bark beetle disturbances. We combined semi-temporary monitoring plots, remote sensing, and GIS in order to understand and model these processes. Sub plots, called “active”, were located in areas with a high probability of bark beetle or wind disturbances. The optimal location of these plots is usually at an active forest edge, i.e., the zone of maximal change in bark beetle abundance over time, corresponding to the border between wind-damaged or bark beetle-attacked parts and undisturbed parts of a forest stand. The key variable investigated was tree mortality caused by bark beetles. Other variables were similar to those recorded in traditional forest monitoring. Tree defense indicators (resin flow, phenolic compounds) and reaction of a tree to bark beetle inoculation were measured. Terrestrial data were then combined with remote sensing data. Time series of satellite images were analyzed in order to define the pattern of wind and bark beetle damages. Weather monitoring data were used for predicting bark beetle and water stress development. All of the information was integrated in a GIS-based system and future bark beetle infestations were predicted. In this paper, we review previous studies and conclude that: (1) the hypotheses of habitat selection (non-host volatiles and semiochemical diversity) and location of moderately-stressed host trees are confirmed, although further work about olfactory orientation and host resistance is needed;(2) reactions of trees to bark beetle attack can be predicted by monitoring several parameters, e.g., air temperature and tree physiology; (3) data from ground monitoring can be integrated with GIS and remote sensing systems for bark beetle prognosis and management at the habitat and landscape levels
