  • Publication number: 20160205931
    Abstract: The present disclosure discusses dodecan-12-olide, and formulations thereof, and its use in detection surveys of, and in mitigation methods for, Emerald Ash Borer beetle infestations of Ash trees.
    Type: Application

  • Patent number: 9226503
    Abstract: The invention disclosed relates to a novel composition and use thereof, for the attraction and detection of emerald ash borer, Agrilus planipennis Fairmaire. The composition comprises (3Z)-dodecen-12-olide and ash foliar or cortical volatiles (green leaf volatiles) associated with a prism trap of a color in the green range of the visible light spectrum. A significant increase in the capture of male A. planipennis is achieved when traps were deployed in the upper tree canopy. This invention is the first demonstration of increased attraction with a combination of a pheromone and a green leaf volatile in a Buprestid species.
    Type: Grant

  • Patent number: 8404225
    Abstract: The invention disclosed relates to the detection of the Emerald Ash Borer (EAB), Agrilus planipennis Fairmaire (Coleoptra: B-prestidae) and in particular to the use of contact sex phenomones therefor. Analysis of the elytral hydrocarbons from male and female emerald ash borer, that were freshly emerged vs. sexually mature (>10 days old) revealed a female-specific compound, 9-methyl-pentacosane (9-Me-C25), only present in sexually mature females. This material was synthesized by the Wittig reaction of 2-decanone with (n-hexadecyl)-triphenylphosphonium bromide followed by catalytic reduction to yield racemic 9-Me C25, which matched the natural compound by GC/MS (retention time and EI-mass spectrum). In field bioassays with freeze-killed sexually mature A. planipennis females, feral males spent significantly more time in contact and attempting copulation with unwashed females than with females that had been washed in n-hexane to remove the cuticular hydrocarbons.
