Population Genetics of Spruce Bark Beetle Ips typographus (Col., Scolytidae) and Related Ips Species1
Enzyme electrophoresis proved to be a useful method to study population genetic aspects in Ips typographus (L.) because of three highly polymorphic loci. Aspartate aminotransferase locus-2 (Aat-2), physiologically involved in the transfer of aminogroups, has six alleles per population. Amylase locus1 (Amy-1), physiologically involved in the hydrolysis of starch, has 10 alleles per population, a...
متن کاملNon-Host Volatile Blend Optimization for Forest Protection against the European Spruce Bark Beetle, Ips typographus
Conifer feeding bark beetles (Coleoptera, Curculionidae, Scolytinae) pose a serious economic threat to forest production. Volatiles released by non-host angiosperm plants (so called non-host volatiles, NHV) have been shown to reduce the risk of attack by many bark beetle species, including the European spruce bark beetle, Ips typographus. However, the most active blend for I. typographus, conta...
متن کاملHost-Tree Monoterpenes and Biosynthesis of Aggregation Pheromones in the Bark Beetle Ips paraconfusus
A paradigm developed in the 1970s that Ips bark beetles biosynthesize their aggregation pheromone components ipsenol and ipsdienol by hydroxylating myrcene, a host tree monoterpene. Similarly, host α-pinene was hydroxylated to a third pheromone component cis-verbenol. In 1990, however, we reported that amounts of ipsenol and ipsdienol produced by male Ips paraconfusus (Coleoptera: Scolytinae) f...
متن کاملBehavioural sequence in the attraction of the bark beetle Ips typographus to pheromone sources
The functions of the two synergistic pheromone components, (4s)-cis-verbenol (cV) and 2-methyl-3-buten-2-01 (MB), and the role of ipsdienol in the attraction of Ips typographus (L.) (Scolytidae) to pheromone sources were studied in the field. Absolute and relative beetle catches were compared between several traps placed at and nearby a central pheromone source: a pipe trap containing the sourc...
متن کاملConifer Stored Resources and Resistance to a Fungus Associated with the Spruce Bark Beetle Ips typographus
Bark beetles and associated fungi are among the greatest natural threats to conifers worldwide. Conifers have potent defenses, but resistance to beetles and fungal pathogens may be reduced if tree stored resources are consumed by fungi rather than used for tree defense. Here, we assessed the relationship between tree stored resources and resistance to Ceratocystis polonica, a phytopathogenic fu...
