  1. Pheromone disruption of Argentine ant trail integrity.

    Journal of Chemical Ecology 34(12):1602 (2008) PMID 19034574

    Disruption of Argentine ant trail following and reduced ability to forage (measured by bait location success) was achieved after presentation of an oversupply of trail pheromone, (Z)-9-hexadecenal. Experiments tested single pheromone point sources and dispersion of a formulation in small field p...
  2. Dolichodial: a new aphid sex pheromone component?

    Journal of Chemical Ecology 34(12):1575 (2008) PMID 19023626

    The sex pheromones of many aphid species from the subfamily Aphididae comprise a mixture of the iridoids (cyclopentanoids) (1R,4aS,7S,7aR)-nepetalactol and (4aS,7S,7aR)-nepetalactone. In this paper, we investigate whether other chemicals, in addition to nepetalactol and nepetalactone, are releas...
  3. No evidence for the induction of brown algal chemical defense by the phytohormones jasmonic acid and methyl jasmonate.

    Journal of Chemical Ecology 34(12):1523 (2008) PMID 19020937

    Induced chemical defense reactions are widespread in marine brown algae. Despite the evidence that the biosynthesis of defense metabolites can be up-regulated upon herbivory, we do not know how this regulation of biosynthetic pathways to secondary metabolites is achieved in brown algae. In highe...
  4. Effects of methyl jasmonate and an endophytic fungus on plant resistance to insect herbivores.

    Journal of Chemical Ecology 34(12):1511 (2008) PMID 18925382

    Tall fescue (Lolium arundinaceum) forms a mutualistic relationship with the fungal endophyte Neotyphodium coenophialum. The endophyte provides constitutive resistance to herbivores through its production of alkaloid compounds. Moreover, herbivore attack induces elevated synthesis of loline alkal...

    Journal of Chemical Ecology 34(12):1593 (2008) PMID 19023627

    An odorant-binding protein cDNA (Acer-ASP2) was cloned and characterized from antennae of adult workers of an Asian honey bee, Apis cerana cerana F. (Hymenoptera: Apidae). The full-length open reading frame of Acer-ASP2 cDNA was 429 bp, encoding 142 amino acids. Protein signature analyses reveal...
  6. Clionapyrrolidine A--a metabolite from the encrusting and excavating sponge Cliona tenuis that kills coral tissue upon contact.

    Journal of Chemical Ecology 34(12):1565 (2008) PMID 19023625

    The Caribbean encrusting and excavating sponge Cliona tenuis successfully competes for space with reef corals by undermining, killing, and displacing live coral tissue at rates of up to 20 cm per year. The crude extract from this sponge, along with the more polar partitions, kills coral tissue a...
  7. Myrcene hydroxylases do not determine enantiomeric composition of pheromonal ipsdienol in Ips spp.

    Journal of Chemical Ecology 34(12):1584 (2008) PMID 19034575

    Myrcene (7-methyl-3-methylene-1,6-octadiene) hydroxylation is likely one of the final reactions involved in the production of the Ips spp. (Coleoptera: Scolytidae) aggregation pheromone components, ipsdienol (2-methyl-6-methylene-2,7-octadien-4-ol) and ipsenol (2-methyl-6-methylene-7-octen-4-ol)...
  8. Cotton plant, Gossypium hirsutum L., defense in response to nitrogen fertilization.

    Journal of Chemical Ecology 34(12):1553 (2008) PMID 19020938

    Plants respond to insect herbivory by producing dynamic changes in an array of defense-related volatile and nonvolatile secondary metabolites. A scaled response relative to herbivory levels and nutrient availability would be adaptive, particularly under nutrient-limited conditions, in minimizing...
  9. Pathogen-induced release of plant allomone manipulates vector insect behavior.

    Journal of Chemical Ecology 34(12):1518 (2008) PMID 19031034

    Infochemicals mediate communication within and between different trophic levels. In this study, we identified a new type of plant allomone induced by a plant pathogen and perceived by its vector insect Cacopsylla picta. This phloem-feeding psyllid is the main vector of Candidatus Phytoplasma mal...
  10. Responses of the pollinating wasp Ceratosolen solmsi marchali to odor variation between two floral stages of Ficus hispida.

    Journal of Chemical Ecology 34(12):1536 (2008) PMID 19015920

    During development of figs on Ficus hispida, only the female floral stage is receptive to its pollinator Ceratosolen solmsi marchali. After this stage, the quantity of fig odor decreases. The effects of F. hispida volatiles from receptive figs (figs at the female floral stage, when they are poll...
  11. New attractants for males of the solanaceous fruit fly Bactrocera latifrons.

    Journal of Chemical Ecology 34(12):1532 (2008) PMID 19018595

    alpha-Ionone, alpha-ionol, and their mixtures with phenolic volatiles act as potential male lures for the solanaceous fruit fly Bactrocera latifrons (Hendel). However, the attractiveness of these compounds is not as strong as that of other well-known tephritid male lures, such as methyl eugenol ...
  12. Essential oil yield and composition reflect browsing damage of junipers.

    Journal of Chemical Ecology 34(12):1545 (2008) PMID 19009322

    The impact of browsing on vegetation depends on the relative density and species composition of browsers. Herbivore density and plant damage can be either site-specific or change seasonally and spatially. For juniper (Juniperus communis) forests of a sand dune region in Hungary, it has been assu...
  13. Virulent Hessian fly larvae manipulate the free amino acid content of host wheat plants.

    Journal of Chemical Ecology 34(11):1401 (2008) PMID 18841417

    Gall-forming insects induce host plants to form specialized structures (galls) that provide immature life stages of the insect access to host plant nutrients and protection from natural enemies. Feeding by larvae of the Hessian fly (Mayetiola destructor Say) causes susceptible host wheat plants ...
  14. Phytotoxic effects of leukamenin E (an ent-kaurene diterpenoid) on root growth and root hair development in Lactuca sativa L. seedlings.

    Journal of Chemical Ecology 34(11):1492 (2008) PMID 18937011

    Leukamenin E, an ent-kaurene diterpenoid isolated from Isodon racemosa (Hemsl) Hara, showed phytotoxic effects on root growth and root hair development of lettuce seedlings (Lactuca sativa L.). Lower concentrations (10 microM) of leukamenin E did not affect root growth, but at concentrations hig...
  15. Amphibian chemical defense: antifungal metabolites of the microsymbiont Janthinobacterium lividum on the salamander Plethodon cinereus.

    Journal of Chemical Ecology 34(11):1422 (2008) PMID 18949519

    Disease has spurred declines in global amphibian populations. In particular, the fungal pathogen Batrachochytrium dendrobatidis has decimated amphibian diversity in some areas unaffected by habitat loss. However, there is little evidence to explain how some amphibian species persist despite infe...
  16. Female crucian carp, Carassius carassius, lose predator avoidance behavior when getting ready to mate.

    Journal of Chemical Ecology 34(11):1487 (2008) PMID 18937012

    In predator-prey interactions, the prey often have to compromise fitness-related behaviors such as feeding, courting, and territorial defense in order to avoid predators. In these trade-off situations, some behaviors have priority over others. These priorities are not rigid, and may be context-d...
