Antibiotic-induced inhibition of pheromone synthesis in a bark beetle.
نویسندگان
چکیده
Ingestion of diet containing streptomycin inhibited the conversion of myrcene, a host plant terpene, to the male-specific pheromones ipsenol and ipsdienol in 1ps paraconfusus. Synthesis of cis-verbenol, which is not a sex-specific pheromone, from the host plant terpene (-)-alpha-pinene and other metabolites from these two terpenes was not inhibited by the antibiotic.

Evaluation of funnel traps for characterizing the bark beetle (Coleoptera: Scolytidae) communities in ponderosa pine forests of north-central Arizona.
Lindgren funnel traps baited with aggregation pheromones are widely used to monitor and manage populations of economically important bark beetles (Coleoptera: Scolytidae). This study was designed to advance our understanding of how funnel trap catches assess bark beetle communities and relative abundance of individual species. In the second year (2005) of a 3-yr study of the bark beetle communi...
متن کاملBark beetle conversion of a plant compound to a sex-specific inhibitor of pheromone attraction.
Both sexes of the bark beetle Dendroctonus brevicomis convert the (+) and (-) enantiomers of the tree terpene alpha-pinene to the corresponding enantiomers of trans-verbenol at about equal rates. (-)-trans-Verbenol inhibited the response of females, but not of males, to a mixture of attractive pheromone components. Since the female initiates the attack on a pine tree, (-)-trans-verbenol may pla...
متن کاملPheromone Biosynthesis in the Bark Beetle, Ips Paraconfusus, during Feeding or Exposure to Vapours of Host Plant Precursors
The quantities of trans-verbenol, myrtenol, and the pheromone, cis-verbenol, in the hindguts of males and females were found to increase in linear proportion following exposure to increasing concentrations of vapour of the host plant precursor, (-)-a-pinene. Males produced significantly more of these compounds than females. Differences between males and females in the ratios of compound product...
متن کاملBark Beetles, Pityogenes bidentatus, Orienting to Aggregation Pheromone Avoid Conifer Monoterpene Odors When Flying but NotWhenWalking
Previous studies and data presented here suggest that odors from healthy host Scotch pine (Pinus sylvestris) and nonhost Norway spruce (Picea abies), as well as major monoterpenes of these trees at natural release rates, significantly reduce the attraction of flying bark beetles, Pityogenes bidentatus, of both sexes to their aggregation pheromone components grandisol and cis-verbenol in the fie...
متن کاملIsolation and functional expression of an animal geranyl diphosphate synthase and its role in bark beetle pheromone biosynthesis.
Geranyl diphosphate synthase (GPPS) catalyzes the condensation of dimethylallyl diphosphate and isopentenyl diphosphate to form geranyl diphosphate. Geranyl diphosphate is the precursor of monoterpenes, a large family of natural occurring C(10) compounds predominantly found in plants. Similar to plants but unique to animals, some bark beetle genera (Coleoptera: Scolytidae) produce monoterpenes ...
