Journal of Japan Association on Odor Environment, 2006 食品，飲料，化粧品，環境計測などの分野では，においを簡便かつ客観的に測定できるセンサーが要求されている．水晶振動子ガスセンサーはかおりの強さとセンサー感度に相関があり，簡便に多様なセンサーを製作することができるので，このセンサーの原理と製作方法を紹介する．水晶振動子ガスセンサーを応用して，複数の要素臭の混ざったにおいを記録し，記録したにおいを再生するにおい記録再生システムの実験について述べる．さらにニーズが見込まれるセンサーとして低濃度の硫化物を検出して識別する口臭センサー，ガス検知管と光学センサーを利用した悪臭センサーについても紹介する．

Entomologia Experimentalis et Applicata, EarlyView.Ticks are obligate ectoparasites that blood‐feed on a variety of vertebrate hosts including rodents such as deer mice, Peromyscus maniculatus bairdii. Female blacklegged ticks, Ixodes scapularis—but not female lone star ticks, Amblyomma americanum, or American dog ticks, Dermacentor variabilis—were attracted to urine‐ and feces‐soiled bedding of male ...

A clinical and mechanistic study on traditional Chinese medicine herbs used in olfactory training
Chinese MedicineBackground Olfactory dysfunction (OD) is a prevalent condition with limited treatment options, severely impairing patients’ quality of life. Olfactory training (OT) using conventional odorants provides limited benefit.

Entomologia Experimentalis et Applicata, EarlyView.Insect herbivores rely on olfactory cues to locate natural‐enemy‐free spaces for feeding or ovipositing; conversely, natural enemies detect herbivores by chemical cues from damaged plants or from the herbivores themselves. Based on the reviewed findings, we suggest that herbivores and natural enemies converge towards using specific olfactory cues. This

Ecological Entomology, EarlyView.Hamiltonella defensa infection increases honeydew production in certain aphid genotypes, potentially modifying aphid feeding behaviour. Parasitoid wasps, Aphidius ervi, are more attracted to honeydew from H. defensa‐infected aphids; though larger honeydew amounts may slightly deter searching.

A preliminary study on the sources of the earthy-musty odorants in Lake Doghu
, 1997 A preliminary study on the sources of the earthy-musty odorants in Lake Donghu were conducted during June 1995-May 1996. Earthy-musty odors in the lake were mainly caused by 2-methylisoborneol (MIB).

Validation studies in novel odorants from different available databases.
, 2019 Bars correspond to means and error bars to the standard error to the mean (SEM). (a) Dravnieks dataset: odorants that fulfill the criteria for the rules woody (a.i), earthy (a.ii), and camphor (a.iii) from our model (Rule (1), black bars) were ...

Fungal infection affects sexual signalling and mate choice in the sugarcane borer
Ecological Entomology, EarlyView.Fungus‐infected Diatraea saccharalis females exhibit enhanced attractiveness to males in wind tunnel assays. Fungal infection alters the pheromone profile of females, increasing the relative abundance of Z9‐16: Ald, a minor but behaviourally active component of the species' sex pheromone blend.

A lipid‐sensitive food choice behavior influences aging outcomes from a longevity‐promoting diet
The FEBS Journal, EarlyView.C. elegans are exposed to a variety of bacteria in their natural environment and must be able to distinguish between beneficial and detrimental food sources. We show that C. elegans exposed to the bacterium from their natural habitat, Methylobacterium, disrupts lipid homeostasis, causing worms to avoid this bacterial species and choose the laboratory ...
