Journal ArticleDOI
Unusual acetylenic sex pheromone of grape leaffolder (Lepidoptera: Pyralidae).
TL;DR: The female-produced sex pheromone of grape leaffolder, Desmia funeralis (Hübner), has been identified as a blend of (Z,Z)-11,13- hexadecadienal, 11-hexadecynal, and (Z-11-hexADEcenal, which increased trap catches approximately twofold when added in appropriate doses to the optimum blend of the other two components.
Journal ArticleDOI
Identification of Volatiles From Plants Infested With Honeydew-Producing Insects, and Attraction of House Flies (Diptera: Muscidae) to These Volatiles
TL;DR: Although fly capture rates in the semifield setting were low, benzaldehyde and (Z)-3-hexenyl acetate were consistently attractive to house flies as individual compounds and as components of volatile blends.
Journal ArticleDOI
A male-produced aggregation-sex pheromone of the beetle Arhopalus rusticus (Coleoptera: Cerambycidae, Spondylinae) may be useful in managing this invasive species.
TL;DR: The pheromone can be exploited as a cost-effective and environmentally safe tool for detection and monitoring of this invasive species at ports of entry, and for monitoring the beetle’s distribution and population trends in both endemic and invasive populations.
Journal ArticleDOI
Sex pheromone blend of the pandora moth (Lepidoptera : Saturniidae), an outbreak pest in pine forests (Pinaceae)
TL;DR: The female-produced sex pheromone blend of the pandora moth, Coloradia pandora pandora Blake, a pest responsible for periodic defoliation of pine forests in the western United States, has been identified.
Journal ArticleDOI
Identification of the sex pheromone of the western poplar clearwing moth (Lepidoptera: Sesiidae)
TL;DR: The sex attractant pheromone for western poplar clearwing, Paranthrene robiniae (Hy. Edwards), was identified by field trapping, gas chromatography, mass spectroscopy, and electroantennography to be approximately a 4:1 ratio of ( E,Z):(Z,Z)-3, 13-octadecadienyl alcohols.
