“…For example, T. dubius (F.), Thanasimus undatulus (Say) and several Zinodosis species are attracted to feeding induced pine volatiles from Ips pini (Say) and Ips grandicollis (Eichhoff) (Erbilgin & Raffa, 2001). Using host volatiles as lures could increase the presence of scolytid predators in the proximity and the subsequent predation pressure on pest populations (Mizell et al, 1983;Chénier & Philogéne, 1988;Erbilgin & Raffa, 2001;Kenis et al, 2004;Costa & Reeve, 2011). Enoclerus nigripes rufiventris (Spinola) and Enoclerus nigrifrons gerhardi Wolcott are attracted to monoterpenes in field assays (Mizell et al, 1983;Chénier & Philogéne, 1988;Costa & Reeve, 2011).…”

1 Exotic invasive ambrosia beetles are among the most economically important pests of nursery stock and forest systems in the U.S.A. 2 Conophthorin, a common bark volatile of deciduous trees, acts as an attractant for the exotic black stem borer, Xylosandrus germanus (Coleoptera: Curculionidae: Scolytinae). Nevertheless, the extent to which a congener, Xylosandrus crassiusculus and other ambrosia beetles are attracted to conophthorin remains unclear. It is also unknown whether conophthorin enhances the attraction of these Xylosandrus beetles to traps baited with ethanol. 3 In the present study, we evaluated the extent to which conophthorin enhances the attraction of X. crassiusculus and X. germanus to ethanol-baited traps. We also tested the capacity of verbenone, an anti-aggregation pheromone component of several coniferophagous bark beetles, to deter both species. 4 More X. crassiusculus were captured in traps baited with both conophthorin and ethanol than in those containing either compound alone, suggesting that conophthorin enhances the response of X. crassiusculus to ethanol. This combination was also attractive to the checkered beetles Madoniella dislocatus and Pyticeroides laticornis (Coleoptera: Cleridae). 5 Verbenone deterred both X. germanus and X. crassiusculus, suggesting that the use of conophthorin and ethanol as an attractant and verbenone as a deterrent can be incorporated into an effective integrated pest management programme.

“…Kenis et al 2004;Wegensteiner 2004) have not been fully understood yet in the context of climate change. Bark beetle parasitoids and predators could play a role in the future as climate change driven agents or simply respond to the population sizes and preferences of their hosts.…”

Climate change is expected to influence the distribution and population dynamics of many insect pests, with potential severe impacts on forests. Spruce bark beetle Ips typographus (L.) (Col.: Curculionidae, Scolytinae) is the most important forest insect pest in Europe whose development is strictly regulated by air temperature. Therefore, climate change is anticipated to induce changes in the pest's distribution and development. We used the PHENIPS model to evaluate climate change impacts on the distribution and voltinism of spruce bark beetle in the Czech Republic. Two future time periods -2025-2050 (near future) and 2075-2100 (distant future) -are addressed. The period 1961-1990 is used as the reference. We found that while a two-generation regime dominated in the Czech Republic in the reference period, significant three-generation regime regions are projected to appear in the near future. In the distant future, the three-generation regime can be expected to occur over all existing coniferous stands in the Czech Republic. The analysis of altitudinal shift of n-generation regime regions indicates noticeable expansion of Ips typographus development to higher elevations, leading for example to disappearance of one-generation regime regions in the distant future. Uncertainties and limitations of the presented findings are discussed as well.

“…The first group feeds on the substrate, most frequently fungi, and some of these species can be beneficial for bark beetles (Kiełczewski et al, 1983). The second group is parasitic or predacious on beetles (Kenis et al, 2004). Both groups can use bark beetles for transport.…”

“…To date, however, it is not clear whether this approach constitutes an effective and practical option for controlling the numbers of bark beetles. In addition, we do not yet know the entire spectrum of phoretic mites accompanying the beetles, nor do we know their direct influence on beetle populations or the details of their ecology (Kenis et al, 2004).…”

Members of the order Mesostigmata frequently use other animals to colonize suitable habitats, and thus their phoretic exploitation of bark beetles is not exceptional. We compared the abundance and species spectrum of phoretic mites in univoltine and bivoltine populations of the European spruce bark beetle Ips typographus. Two localities with high population densities of Ips typographus in the eastern part of the Czech Republic (400 and 1100 m a.s.l.) were studied. Beetles were sampled with pheromone traps baited with IT Ecolure (5 per locality). In total, 1268 I. typographus individuals were captured, from which 1662 mite individuals were collected and 8 species of phoretic mites were identified. The most numerous species were Dendrolaelaps quadrisetus and Trichouropoda polytricha. Trichouropoda polytricha was dominant at the higher elevation (1100 m a.s.l.). Neither the number of phoretic mites per beetle nor the percentage of beetles carrying the mites differed between the localities. At the locality with bivoltine beetle populations, however, the number of phoretic mites per beetle was greater in the spring generation than in the summer generation.
