An Innate Preference of Bumblebees for Volatile Organic Compounds Emitted by Phaseolus vulgaris Plants Infected With Three Different Viruses

open access: yesFrontiers in Ecology and Evolution, 2021
Cucumber mosaic virus (CMV)-infected tomato (Solanum lycopersicum L.) plants emit volatile organic compounds (VOCs) attractive to bumblebees (Bombus terrestris L.), which are important tomato pollinators, but which do not transmit CMV. We investigated if

Reverse chemical ecology approach for the identification of an oviposition attractant for Culex quinquefasciatus. [PDF]

open access: yes, 2018
Pheromones and other semiochemicals play a crucial role in today's integrated pest and vector management strategies. These semiochemicals are typically discovered by bioassay-guided approaches.

A New Experimental Setup to Study the Olfactory Behaviour of Trichogramma Egg Parasitoids

open access: yesEntomologia Experimentalis et Applicata, EarlyView.
We developed an experimental setup to assess odor‐induced egg‐laying behavior in tiny egg‐parasitoid wasps. This Y‐shaped olfactometer, coupled with an AI‐based image‐recognition model, automatically quantifies egg parasitism by Trichogramma wasps. Olfactory‐driven egg‐laying preferences were analyzed using Bayesian inference.

Sex Pheromone of the Introduced Pine Sawfly, Diprion similis, Revisited to Define a Useful Monitoring Lure: Deviating Chiral Composition and Behavioural Responses Compared to Earlier Reports

open access: yesInsects, 2021
Extracts of Diprion similis females contained about 15 ng of the sex pheromone precursor 3,7-dimethylpentadecan-2-ol per female. After derivatisation with (S)-2-acetoxypropanoyl chloride, we found that the major stereoisomer in the extract was (2S,3R,7R)-

Computational reverse chemical ecology: Virtual screening and predicting behaviorally active semiochemicals for Bactrocera dorsalis [PDF]

open access: yes, 2014
BACKGROUND: Semiochemical is a generic term used for a chemical substance that influences the behaviour of an organism. It is a common term used in the field of chemical ecology to encompass pheromones, allomones, kairomones, attractants and repellents ...

Using a Generic Blend of Pheromones to Simultaneously Attract a Diversity of Elaterid Beetle Species Native to Eastern North America

open access: yesEntomologia Experimentalis et Applicata, EarlyView.
We assessed attraction of eight elaterid species to a “generic” pheromone blend containing their eight known pheromones or sex attractants. All eight species were attracted by their specific attractants, as expected. Six species were attracted to the blend, but the remaining two species were strongly inhibited by unknown blend components.

Odour perception in the codling moth Cydia pomonella L. [PDF]

open access: yes, 2004
The codling moth, Cydia pomonella L. (Lepidoptera: Tortricidae) is a renowned pest in apple, pear and walnut orchards, and its activities are in large guided by volatile odours as sensory cues.

Landscape and Geography Determine Saproxylic Beetle Captures in Pheromone‐Baited Traps

open access: yesEntomologia Experimentalis et Applicata, EarlyView.
Pheromone‐baited traps at 39 forest sites across southern Sweden captured 58 saproxylic beetle species, including seven Red‐listed taxa. The effect of surrounding forest cover on beetle abundance may depend on latitude and longitude: positive effects were strongest in warmer southern and eastern regions but weakened or reversed in colder northwestern ...

Acttra SWD Bait Formulation Against Drosophila Suzukii and its Compatibility with Berry Pollination by the Honey Bee, Apis Mellifera

open access: yesJournal of Apicultural Science, 2021
Crop protection substances are continuously developed to prevent the decimation of non-target insect populations through insecticide use. The bait formulation Acttra SWD was created to attract the adult spotted-wing drosophila, a generalist pest of ...

Comparing Methods for Measuring Predation: Toward a Quantitative–Informative Indicator of Natural Pest Control

open access: yesEntomologia Experimentalis et Applicata, EarlyView.
Predation methods vary widely in their ability to quantify biological control. Estimating predation rates (the number of prey killed per predator per time unit) is crucial. Combining predation rates with predator abundance yields real‐time field estimates of pests consumed.
