Thanasimus formicarius responded in different numbers to traps baited with exo-brevicomin alone or in combination with ethanol as well as to a mixture of ipsenol, ipsdienol and (S)-cis-verbenol; compounds produced by and/or attractive to bark beetle

Chances and limits of using synthetic pheromones in bark beetle management. A successful point-application of synthetic pheromones in bark beetle management depends on the timely removal of baited trees if trap trees are used. The direct application

Applicability of bark beetle pheromones: Configuration and consequences Recent field tests with optically pure isomeres of the pheromones brevicomin, frontalin and ipsenol indicate biological activity for only one of the possible stereochemical antip

New results on bark beetle pheromones are presented and discussed along with a critical review on recent investigations in this field. Male specific compounds of the spruce bark beetle Polygraphus poligraphus are identified as trans- and cis-4-thujan

Studies on effect and formulation of the Trypodendron attractant “Lineatin” (±) 3,3,7-trimethyl-2,9-dioxatricyclo (3.3.1.04,7) nonane (“lineatin”) proved highly attractive at low concentrations to populations of T. lineatum in the Black Fore

Populations of the southern pine beetle, Dendroctonus frontalis, from the loblolly pine region of the United States differed in pheromone production and did not interbreed with beetles attacking Pinus leiophylla in central Mexico. Beetles collected f

Chemical characteristics of pine resin (Pinus spp.) Extensive knowledge of the chemical composition of pine resins may contribute to the resolution of chemotaxonomic problems as well as to a better understanding of significant insect/plant relationsh

The aggregation pheromone system of Ips cembrae appears to consist of three compounds produced by attacking males. Gas chromatographic analysis of hindgut volatiles revealed the presence of ipsenol, ipsdienol and an additional compound which was iden

Interactions between resin flow and subcortically feeding Coleoptera Under investigation is the dual function which oleoresin apparently has in the colonization of conifers, particularly pine trees, by subcortically feeding insects: Oleoresin represe
