Ips confusus and Ips paraconfusus IDENTITY Taxonomic position: Insecta: Coleoptera: Scolytidae Notes on taxonomy and nomenclature: Although the quarantine pest which appears in the EPPO and EU lists is named as I. confusus, Furniss & Carolin (1977) explain that this species, the piñon ips,...
1984. Pheromone production by axenically reared Dendroc- tonus ponderosae and Ips paraconfusus (Coleoptera: Scolytidae). J. Chem. Ecol. 2:281-90Pheromone production by axenically reared Dendroctonus ponderosae and Ips paraconfusus (Coleoptera: Scolytidae)[J] . J. E. Conn,J. H. Borden,D. W...
paraconfusus and I. pini individuals the de novo production of ipsenol and ipsdienol from acetate. The molecular basis for de novo synthesis involves the interaction of juvenile hormone III and HMG-CoA reductase in the mevalonate biosynthetic pathway to produce monoterpenoids, the precursors to ...
MaleI. paraconfusus confined to artificial entrance tunnels in white fir logs produced the pheromone compounds ipsenol and ipsdienol in their hindguts. The hindguts were attractive to females in a laboratory olfactometer and the male infested logs were attractive in field bioassay. The amount of...
Pheromones and metabolites of host (ponderosa pine) compounds were found in association with the hindgut of both naturally fed and of non-fed, host vapour-exposed bark beetles, Ips paraconfusus and Dendroctonus brevicomis. Much smaller amounts were found in the corresponding heads and mid guts....
In 1990, however, we reported that amounts of ipsenol and ipsdienol produced by male Ips paraconfusus (Coleoptera: Scolytinae) feeding in five host pine species were nearly the same, even though no detectable myrcene precursor was detected in one of these pines (Pinus sabiniana). Subsequent ...
Synthetic juvenile hormone (JH) induced the synthesis of the three pheromones, ipsenol, ipsdienol and 2-phenylethanol, by Ips paraconfusus males and enhanced the conversion of (–)-α-pinene to a fourth pheromome, cis -verbenol. Synthetic JH also mimicked the stimulatory effect of feeding on...
Ips paraconfusus Lanier, 1970b Distribution: USA: California, western Nevada, western Oregon. Principal hosts: Pinus attenuate Lemmon, P. coulteri Lamb. ex D. Don, P. jeffreyi, P. lambertiana Douglas, and P. ponderosa. Diagnosis: There are five spines on the elytral declivity and its gen...
