Male-Produced Aggregation Pheromone of the Cerambycid Beetle Neoclytus acuminatus acuminatus
Females of the cerambycidCurius dentatus Newman were attracted to traps baited with the four component blend, suggesting that a male-produced sex pheromone for this species may contain (2R,3S)- hexanediol and/or (2S,3R)-hexanediol.
Role of Contact Pheromones in Mate Recognition in Xylotrechus colonus
Stripping cuticular hydrocarbons from females with solvent rendered them unattractive to males, suggesting that males did not recognize females by mechanoreception alone, but reapplying solvent extract to washed females restored their attractiveness, confirming the role of cuticular Hydrocarbons in mate recognition.
Fuscumol and fuscumol acetate are general attractants for many species of cerambycid beetles in the subfamily Lamiinae
The hypothesis that fuscumol and fuskumol acetate are widespread pheromone components or attractants for a variety of cerambycid species, especially lamiines in the tribe Acanthocinini is supported.
(Z)-9-Pentacosene − contact sex pheromone of the locust borer, Megacyllene robiniae
Data indicate that Z9:C25 is a contact sex pheromone of M. robiniae, being the most abundant hydrocarbon on the surface of the cuticular wax layer of females where it is readily accessible to the antennae of males.
Contact Pheromones as Mate Recognition Cues of Four Species of Longhorned Beetles (Coleoptera: Cerambycidae)
It is found that nonpolar compounds on the cuticle of females are essential for mate recognition in all four species and are further evidence of the critical role of contact pheromones in mating systems of longhorned beetles.
ROLE OF HOST PLANT VOLATILES IN MATE LOCATION FOR THREE SPECIES OF LONGHORNED BEETLES
Evaluating the first behavioral stage of mate location behavior for the same three species finds both males and females responded to volatiles emanating from hickory logs in Y-tube olfactometer bioassays.
First Contact Pheromone Identified for a Longhorned Beetle (Coleoptera: Cerambycidae) in the Subfamily Prioninae
This work explored the chemically-mediated mating behavior of Mallodon dasystomus, the hardwood stump borer, and tested the hypothesis that males recognize females by a contact pheromone, finding further evidence of the critical role of contact phersomones in mating systems of longhorned beetles.
The capacity of conophthorin to enhance the attraction of two Xylosandrus species (Coleoptera: Curculionidae: Scolytinae) to ethanol and the efficacy of verbenone as a deterrent
The capacity of verbenone, an anti‐aggregation pheromone component of several coniferophagous bark beetles, to deter both X. germanus and X. crassiusculus is tested, suggesting that the use of conophthorin and ethanol as an attractant and Verbenone as a deterrent can be incorporated into an effective integrated pest management programme.
Evaluating Western Corn Rootworm (Coleoptera: Chrysomelidae) Emergence and Root Damage in a Seed Mix Refuge
The proportion of beetles emerging from refuge plants was significantly greater in a block and strip refuge structure than in a seed mix refuge, and more beetles emerged from Bt-RW corn plants when they were grown as part of a seed mixture.
Geosmithia morbida found on weevil species Stenomimus pallidus in Indiana.
In an Indiana-wide trap-tree survey of ambrosia and bark beetles and weevils colonizing stressed Juglans nigra, G. morbida was detected on three Stenomimus pallidus weevil emerged from two trees on one site, the first report of the pathogen in Indiana and the first reported of the fungus from an insect species other than P. juglandis.
