Genome and transcriptome‐based identification and expression profiling of chemosensory gene families across developmental stages and tissues in Sirex noctilio (Hymenoptera: Siricidae)

Insect Molecular Biology, EarlyView.
The first draft genome of Sirex noctilio was produced. Fifteen S. noctilio transcriptomes were sequenced to study chemosensory gene expression patterns. SnocOR16 and SnocSNMP1 displayed tissue‐ and sex‐specific expression patterns. Abstract The Sirex woodwasp (Sirex noctilio; Hymenoptera: Siricidae) is among the most destructive invasive pests ...

Drought Stress Promotes Aphis gossypii Growth but Decreases Host Attractiveness in Melon

Journal of Applied Entomology, EarlyView.
ABSTRACT Drought stress is a significant environmental factor that affects plant physiology and growth, leading to considerable detrimental effects on crop productivity. Cucumis melo, which is widely cultivated for its economic value, is particularly susceptible to water scarcity.

A Novel Olfactometer for Efficient and Flexible Odorant Delivery [PDF]

Chemical Senses, 2018
Abstract Understanding how sensory space maps to neural activity in the olfactory system requires efficiently and flexibly delivering numerous odorants within single experimental preparations. Such delivery is difficult with current olfactometer designs, which typically include limited numbers of stimulus channels and are subject to ...

Shrubs and trees as natural insect protection for grazing animals in Switzerland and the alpine region: A systematic review of in vitro, in vivo and clinical trials Sträucher und Bäume als natürlicher Insektenschutz für Weidetiere in der Schweiz und im Alpenraum: Eine systematische Literaturübersicht über in vitro‐, in vivo‐ und klinische Studien

Medical and Veterinary Entomology, EarlyView.
Biting or irritating insects are a threat to the health and welfare of grazing animals. This systematic review reveals that several shrubs and bushes growing in the alpine area have insecticidal, insect‐repellent and/or attractant properties. The alder Alnus glutinosa, juniper Juniperus communis, spruce Picea abies and walnut Juglans regia are ...

Gonadal hormones, but not sex, affect the acquisition and maintenance of a Go/No-Go odor discrimination task in mice [PDF]

, 2018
In mice, olfaction is crucial for identifying social odors (pheromones) that signal the presence of suitable mates. We used a custom-built olfactometer and a thirst-motivated olfactory discrimination Go/No-Go (GNG) task to ask whether discrimination of ...

Conspecific cueing or cooperative feeding?—Foraging stable flies are visually attracted to conspecific flies

Medical and Veterinary Entomology, EarlyView.
In two‐choice laboratory bioassays, food‐deprived and CO2‐stimulated stable flies were offered paired landing platforms that were baited or not (control) with conspecific flies. The presence of conspecifics prompted the attraction and landing of foraging stable flies.

Chemosensory Event-Related Potentials in Response to Nasal Propylene Glycol Stimulation

Frontiers in Human Neuroscience, 2019
Propylene glycol, also denoted as 1.2 propanediol (C3H8O2), often serves as a solvent for dilution of olfactory stimuli. It is supposed to serve as a neutral substance and has been used in many behavioral and electrophysiological studies to dilute pure ...
