Behavioural 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...
متن کاملPopulation 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 کاملWhat is Next in Bark Beetle Phylogeography?
Bark beetle species within the scolytid genera Dendroctonus, Ips, Pityogenes and Tomicus are known to cause extensive ecological and economical damage in spruce and pine forests during epidemic outbreaks all around the world. Dendroctonus ponderosae poses the most recent example having destroyed almost 100,000 km² of conifer forests in North America. The success and effectiveness of scolytid sp...
متن کاملFine structure of degenerating and regenerating flight muscles in a bark beetle, Ips confusus. II. Regeneration.
The flight muscles of the bark beetle Ips confusus undergo a pronounced degeneration within 4 days of introducing beetles into the bark of pine logs. Numerous lysosomes develop between the myofibrils, and the fibrils become greatly reduced in size. In female beetles many of the mitochondria and most of the myofilaments disappear from the muscle, and apart from lysosomes, tracheoles and a few fi...
