Identification of the sex pheromone of Conogethes pluto: a pest of Alpinia
25-11-2012 | Ashraf M. El-Sayed, Andrew R. Gibb, Vanessa J. Mitchell, Lee-Anne M. Manning, John Revell, Brian Thistleton, David M ..., Chemoecology, 2012
In recent years, Conogethes pluto (Lepidoptera: Crambidae) has become a major pest of Alpinia and other ornamental gingers in the Northern Territory and Queensland, Australia. This pest damages the flowers and bores into the stems, causing substantial losses to production. Currently, no ...
Population and leaf-level variation of iridoid glycosides in the invasive weed Verbascum thapsus L. (common mullein): implications for herbivory by generalist insects
19-11-2012 | Christina Alba, Ryan Prioreschi, Carolina Quintero, Chemoecology, 2012
Plant–insect interactions, which are strongly mediated by chemical defenses, have the potential to shape invasion dynamics. Despite this, few studies have quantified natural variation in key defensive compounds of invasive plant populations, or how those defenses relate to levels of ...
Dealing with double trouble: consequences of single and double herbivory in Brassica juncea
07-11-2012 | Vartika Mathur, Tom O. G. Tytgat, Rob M. de Graaf, Vinay Kalia, A. Sankara Reddy, Louise E. M. Vet, Nicole M. van Dam, Chemoecology, 2012
In their natural environment, plants are often attacked simultaneously by many insect species. The specificity of induced plant responses that is reported after single herbivore attacks may be compromised under double herbivory and this may influence later arriving herbivores. The present ...
Physiological benefits of feeding in the spring by Lymantria dispar caterpillars on red oak and sugar maple leaves: nutrition versus oxidative stress
02-11-2012 | Raymond V. Barbehenn, Julie Niewiadomski, Cristina Pecci, Juha-Pekka Salminen, Chemoecology, 2012
The rapid growth of insects that feed on tree leaves in the spring is believed to be due to high nutritional quality. This study tested the hypothesis that both high nutritional quality and low levels of oxidative stress (i.e., toxicological effects) benefit caterpillars that feed in the ...
The multifunctional pygidial gland secretion of the Steninae (Coleoptera: staphylinidae): ecological significance and evolution
29-10-2012 | Andreas Schierling, Karlheinz Seifert, Sebastian R. Sinterhauf, Julian B. Rieß, Johanna C. Rupprecht, Konrad Dettner, Chemoecology, 2012
The pygidial gland secretion of the rove beetle genera Stenus Latreille and Dianous Leach is composed of pyridine and piperidine-derived alkaloids and several terpene compounds. Two-choice bioassays with ants and fish, as well as agar diffusion assays, revealed that the secretion compounds ...
Reevaluation of the sex pheromone of the lesser date moth, Batrachedra amydraula, using autosampling SPME-GC/MS and field bioassays
13-10-2012 | Anat Levi-Zada, Avraham Sadowsky, Svetlana Dobrinin, Maayan David, Tamir Ticuchinski, Daniela Fefer, Amnon Greenberg ..., Chemoecology, 2012
In a previous study of the sex pheromone of the lesser date moth, Batrachedra amydraula, using laboratory females, (Z4,Z7)-4,7-decadien-1-yl acetate, Z4-decen-1-yl acetate, Z5-decen-1-yl acetate and decyl acetate were identified by sequential SPME-GC/MS analysis. Traces of Z5-decen-1-ol were ...
Field bioassays of cerambycid pheromones reveal widespread parsimony of pheromone structures, enhancement by host plant volatiles, and antagonism by components from heterospecifics
13-10-2012 | Lawrence M. Hanks, Jocelyn G. Millar, Chemoecology, 2012
Recent research has revealed extensive pheromonal parsimony within the large beetle family Cerambycidae, with closely related species producing the same or very similar pheromone components. This article summarizes research that evaluated attraction of cerambycids to individual pheromone ...
Making scents of defense: do fecal shields and herbivore-caused volatiles match host plant chemical profiles?
13-10-2012 | Ken Keefover-Ring, Chemoecology, 2012
Many plant families have aromatic species that produce volatile compounds which they release when damaged, particularly after suffering herbivory. Monarda fistulosa (Lamiaceae) makes and stores volatile essential oils in peltate glandular trichomes on leaf and floral surfaces. This study ...
The effects of simulated acid rain and heavy metal pollution on the mountain birch–autumnal moth interaction
22-09-2012 | Tapio van Ooik, Markus J. Rantala, Juha-Pekka Salminen, Shiyong Yang, Seppo Neuvonen, Teija Ruuhola, Chemoecology, 2012
The exposure of plants to abiotic stresses like air pollutants may increase their susceptibility to herbivores. However, abiotic stresses often induce the accumulation of phenolic compounds that may have adverse effects on plant-eating animals. In this study, we examined the effects of ...
Transient abiotic stresses lead to latent defense and reproductive responses over the Brassica rapa life cycle
21-09-2012 | Adam D. Steinbrenner, Niels Agerbirk, Colin M. Orians, Frances S. Chew, Chemoecology, 2012
Plants can alter physiological and developmental trajectories in response to environmental cues by means of phenotypic plasticity. While cases of immediate plastic responses to different environments are well studied, phenotypic changes can also be delayed and occur in later life cycle ...
