Effects of non‐host traces on behavioural responses of an egg parasitoid to substrate‐borne semiochemicals in a multi‐herbivore scenario

open access: yesEcological Entomology, EarlyView.
In open arena assays, the response of the egg parasitoid Trissolcus basalis to substrate‐borne semiochemicals left by the host Nezara viridula was affected by the non‐host Spodoptera littoralis. Non‐host larval traces reduced T. basalis residence time spent on walking traces from gravid N. viridula females but did not affect responses to walking traces

Characterizing Sexual Selection in a Wild Population of Protopiophila litigata (Diptera: Piophilidae) and Analyzing the Combined Effects of Cuticular Hydrocarbons and Wing Interference Patterns on Male Mating Success in Drosophila serrata

open access: yes, 2017
One of the major research challenges is the ability to test selective forces in a wild population. A recent discovery of a new dipteran species, Protopiophila litigata, can enable researches to test selection in the wild.

Maternal factors from a parasitoid wasp mediate hyperparasitoid attraction to parasitized caterpillars

open access: yesEcological Entomology, EarlyView.
The parasitoid‐associated polydnavirus CgPDV, but not venom alone, significantly increases the attractiveness of Pieris brassicae caterpillars to the hyperparasitoid Baryscapus galactopus at close range. Naturally parasitized caterpillars elicit stronger hyperparasitoid attraction than any injection treatment, indicating that additional factors beyond ...

Fungal infection affects sexual signalling and mate choice in the sugarcane borer

open access: yesEcological 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.

Declining habitat directive butterflies within a major stronghold: Challenges for conservation Rückläufige Tagfalter der FFH‐Richtlinie in einer bedeutenden Hochburg: Herausforderungen für den Naturschutz

open access: yesInsect Conservation and Diversity, EarlyView.
Myrmecophilous Phengaris nausithous and P. teleius are highly specialized grassland butterflies and flagship species for European nature conservation, but they exhibit ongoing population declines. We show strong declines for both species in the Westerwald mountain range, western Germany, since 1994, driven by inappropriate timing of mowing, grassland ...

Trans‐resveratrol alleviates inflammation and improves skin barrier function via aryl hydrocarbon receptor pathway in human reconstructed epidermis

open access: yesInternational Journal of Cosmetic Science, EarlyView.
In a cytokine‐challenged human epidermal model, trans‐resveratrol reduces inflammation (IL‐1α) and oxidative stress markers (CYP1A1, CYP1B1), while modulating the expression of barrier‐related genes (LOR, OCLN) and differentiation‐associated CASP14. This supports its role as a multifunctional active for sensitive and compromised skin.

Cuticular Hydrocarbons of Glacially-Preserved Melanoplus (Orthoptera: Acrididae): Identification and Comparison with Hydrocarbons of M. sanguinipes and M. spretus [PDF]

open access: yes, 1996
The cuticular hydrocarbons of four groups of grasshoppers were identified and quantified by capillary column gas-liquid chromatography (GLC) and GLC-mass spectrometry (GLC-MS), including samples of: 1) a modern species, M.

Pretreatment of keratinocytes with Galactomyces ferment filtrate (GFF) promotes stress resiliency in an in vitro oxidative stress model

open access: yesInternational Journal of Cosmetic Science, EarlyView.
GFF pretreatment enhances keratinocyte protection against oxidative stress by mitigating stress‐induced biomolecular changes and gene expression dysregulation. GFF‐pretreated keratinocytes maintain healthy epidermal biology post‐stress, preserving mitochondrial function and proliferative capacity.

Epigenetic and Metabolic Changes That Drive Trained Immunity in Response to Microbes and Vaccines

open access: yesImmunology, EarlyView.
This graphical abstract illustrates how microbial products, vaccines and microbial metabolites activate pattern‐recognition receptor signalling, inducing metabolic rewiring and epigenetic remodelling. These changes establish long‐lasting trained immunity through the functional reprogramming of haematopoietic progenitors and innate immune cells, thereby
