  1. Field evaluation of the bacterial volatile derivative 3-pentanol in priming for induced resistance in pepper.

    Journal of Chemical Ecology 40(8):882 (2014) PMID 25149655

    We investigated the ISR capacity of VOCs and derivatives collected from strain IN937a against bacterial spot disease caused by Xanthomonas axonopodis pv. vesicatoria in pepper. Of 15 bacterial VOCs and their derivatives, 3-pentanol, which is a C8 amyl alcohol reported to be a component of sex pherom...
  2. Identification and biosynthesis of novel male specific esters in the wings of the tropical butterfly, Bicyclus martius sanaos.

    Journal of Chemical Ecology 40(6):549 (2014) PMID 24894159 PMCID PMC4090810

    We report the identification and biosynthetic pathways of several novel esters from the wings of male B. martius sanaos. We found that the volatile compounds in this male butterfly were similar to female-produced moth sex pheromones. Components associated with the male wing androconial areas were id...
  3. The inverted phantom giant.

    Journal of Chemical Ecology 40(5):417 (2014) PMID 24832064

  4. Nectar minerals as regulators of flower visitation in stingless bees and nectar hoarding wasps.

    Journal of Chemical Ecology 40(5):476 (2014) PMID 24888745

    Various nectar components have a repellent effect on flower visitors, and their adaptive advantages for the plant are not well understood. Persea americana (avocado) is an example of a plant that secretes nectar with repellent components. It was demonstrated that the mineral constituents of this nec...
  5. Involvement of a specific chemosensory protein from Bactrocera dorsalis in perceiving host plant volatiles.

    Journal of Chemical Ecology 40(3):267 (2014) PMID 24627092

    Insects have evolved many physiological and behavioral adaptations to recognize external complex chemicals. Olfaction plays an important role in perceiving volatile chemicals, utilizing them to locate host sites, conspecifics, and enemies. Chemosensory proteins (CSPs) are present in high concentrati...
  6. Brassica plant responses to mild herbivore stress elicited by two specialist insects from different feeding guilds.

    Journal of Chemical Ecology 40(2):136 (2014) PMID 24500734

    These results have implications for the understanding of plasticity in plant defenses against herbivores and for the management of Brassica rapa in agroecosystems....
  7. Terpenes tell different tales at different scales: glimpses into the Chemical Ecology of conifer - bark beetle - microbial interactions.

    Journal of Chemical Ecology 40(1):1 (2014) PMID 24337719

    I approach this problem by focusing primarily on one chemical group, terpenes, by emphasizing the curvilinear and threshold-structured basis of most underlying relationships, and by focusing on the system's feedback structure, which can either buffer or amplify relationships across scales....
  8. Real-time monitoring of (E)-β-farnesene emission in colonies of the pea aphid, Acyrthosiphon pisum, under lacewing and ladybird predation.

    Journal of Chemical Ecology 39(10):1254 (2013) PMID 24158268

    We present the first long-time monitoring of EBF emission in aphid colonies using real-time monitoring. We used a zNose(TM) to analyze the headspace of colonies of the pea aphid, under lacewing (Neuroptera: Chrysopidae) and ladybird (Coleoptera: Coccinellidae) predation, over 24 hr. We found no emis...
  9. Microbial detoxification of mycotoxins.

    Journal of Chemical Ecology 39(7):907 (2013) PMID 23846184

    Mycotoxins are fungal natural products that are toxic to vertebrate animals including humans. Microbes have been identified that enzymatically convert aflatoxin, zearalenone, ochratoxin, patulin, fumonisin, deoxynivalenol, and T-2 toxin to less toxic products. Mycotoxin-degrading fungi and bacteria...
  10. Human skin volatiles: a review.

    Journal of Chemical Ecology 39(5):569 (2013) PMID 23615881

    We detail the different sampling techniques, each with its own set of advantages and disadvantages, which have been used for the collection of skin odors from different parts of the human body. We present the main skin volatile compounds found in these studies, with particular emphasis on the most f...
