Olfactory recognition and behavioural avoidance of angiosperm nonhost volatiles by conifer‐inhabiting bark beetles
When searching for suitable hosts in flight, conifer‐inhabiting bark beetles will encounter not only suitable host trees and their odours, but also unsuitable hosts and nonhost trees. Expand
Orchids Mimic Green-Leaf Volatiles to Attract Prey-Hunting Wasps for Pollination
This work demonstrates for the first time that the flowers of E. helleborine and E. purpurata emit green-leaf volatiles (GLVs), which are attractive to foragers of the social wasps Vespula germanica and V. vulgaris and are implicated in chemical mimicry for the attraction of pollinating insects.

Evaluation of herbivore-induced plant volatiles for monitoring green lacewings in Washington apple orchards
Despite the obvious promise of HIPVs in biological control programs, the data have revealed C. nigricornis to be an abundant orchard predator that can be readily monitored with squalene-baited traps, and urge caution in their deployment as large-scale attractants. Expand
Green Leaf Volatiles Interrupt Pheromone Response of Spruce Bark Beetle, Ips typographus
A synthetic mixture of nine green leaf volatiles (GLVs) including linalool was tested on antennae of Ips typographus (L.) with coupled gas chromatographic–electroantennographic detection (GC-EAD).Expand
Behavioral responses for evaluating the attractiveness of specific tea shoot volatiles to the tea green leafhopper, Empoaca vitis
The results indicate that the bud‐green sticky traps baited with tea shoot volatiles can provide a new tool for monitoring and managing the tea leafhopper. Expand
Semiochemistry of the Goldeneyed Lacewing Chrysopa oculata: Attraction of Males to a Male-Produced Pheromone
(1R,2S,5R,8R)-iridodial (or its enantiomer) is now identified as a male-produced male aggregation pheromone for Co. oculata, the first phersomone identified for lacewings. Expand
Catching Ips duplicatus (Sahlberg) (Coleoptera: Scolytidae) with pheromone-baited traps: optimal trap type, colour, height and distance to infestation.
The optimal trap characteristics will improve the performance of pheromone-baited traps as a critical monitoring or mass-trapping tool to combat outbreaks of this pest species. Expand
Redundancy, synergism, and active inhibitory range of non‐host volatiles in reducing pheromone attraction in European spruce bark beetle Ips typographus
The hypothesis that as mixed forests have greater semiochemical diversity than pure host stands; they disturb olfactory guided host choice, and may reduce the possibility of outbreaks of conifer-infesting bark beetles is supported. Expand
Leaf Volatiles from Nonhost Deciduous Trees: Variation by Tree Species, Season and Temperature, and Electrophysiological Activity in Ips typographus
The leaf volatiles emitted from four nonhost tree species of Ips typographus, i.e. Betula pendula, B. pubescens, Populus tremula, and Sambucus nigra, were collected outdoors by headspace sampling inExpand
A successful Case of Pheromone Mass Trapping of the Bark Beetle Ips duplicatus in a Forest Island, Analysed by 20-year Time-Series Data
The experimental testing of the hypothesis of population reduction by mass trapping with the establishment of treatment/control areas is a logistic problem on landscape scale. We suggest a possibleExpand
