The chemical ecology of the lesser chestnut weevil : behavioral and electrophysiological responses of Curculio sayi (Coleoptera: curculionidae) to host-plant volatile organic compounds
(University of Missouri--Columbia, 2011)The most abundant volatile organic compounds (VOC) from chestnut reproductive plant tissue (catkin, nut and bur) were identified with gas chromatography and mass-spectrometry (GC-MS). Two-choice behavioral bioassays were ... -

(University of Missouri--Columbia, 2007)Chestnut trees were once a dominant sight across the deciduous forest of the eastern and central United States, but following a devastating blight in the early 1900's much of the native range for this tree species has been ... -
The sublethal effects of ecdysone agonists on the attractiveness, responsiveness, fertility and fecundity of oriental fruit moth, a comparative examination with codling moth on larval feeding damage
(University of Missouri--Columbia, 2006)The ecdysone agonists methoxyfenozide and tebufenozide are designed to affect the larval stage of Lepidopteran pests. Recent studies have reported sublethal effects on the adults of several tortricid apple tree pests exposed ... -
The sublethal effects of methoxyfenozide on the field orientation and courtship behavior of Cydia pomonella (Linnaeus) (Lepidoptera: tortricidae)
(University of Missouri--Columbia, 2008)The sublethal effects of ecdysone agonist methoxyfenozide on the mating behavior and field orientation of codling moth, Cydia pomonella (Linnaeus), was examined. Five different lure types were placed in the upper canopy ...
