Cost of parasite exposure depends on host ontogeny 寄生接觸的代價依賴於宿主發育階段
Ecological Entomology, EarlyView.The cost of parasite exposure varies across host developmental stages, demonstrating that ontogeny influences the expression of non‐consumptive effects (NCEs). Mite exposure resulted in consumptive effects in fly eggs and NCEs in early‐stage pupae; mite longevity was comparable when provisioned with pupae or water but increased when provisioned with ...

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.

An Easy Method to Sample Headspace Pheromones in the Field
Ethology, EarlyView.Females of the orb‐web spider Argiope bruennichi produces a pheromone to attract males for mating. Most of our knowledge about the pheromone and its strategical use by the females is known from the laboratory. While we have confidence in the validity of these results, we wanted to make sure and measure pheromones in the field.

Aliens vs. paper wasps: new records of Darwin wasps parasitizing social wasps in Brazil
Revista de la Sociedad Entomológica ArgentinaThis study reports new associations between Ichneumonidae and social wasps, contributing to the under-standing of the ecological relationships between species and expanding current knowledge of their geo-graphic distribution. We identified a total of five Ichneumonidae species associated with colonies of five species of social wasps.

A protracted phenology: Post‐diapause larval development of a threatened butterfly
Insect Conservation and Diversity, EarlyView.Larval survival during diapause was high; hibernaculum webs were mostly located near Succisa pratensis plants, which often retained vital leaves through winter. Post‐diapause developmental time varied strongly depending on exposure to different microclimates, being reduced by litter cover, solar radiation and a higher heat load index.

Neuronal Extracellular Vesicles Carrying APOE Downregulate Filament Actin Polymerization Signaling to Inhibit Synapse Formation in Alzheimer's Disease. [PDF]
J Extracell VesiclesDuring AD progression, EVs derived from APP/PS1 neurons transport APOE into healthy neurons, potentially interacting with neuronal APOE receptors (LRP1, LDLR, VLDLR) to transduction the signaling. This signaling inhibits Rac1‐GTP activation and subsequently downregulates F‐actin polymerization through the Rac1‐N‐WASP‐Arp2/3 pathway.

Insect Molecular Biology, EarlyView.Comparison between developmental stages (larvae, pupae, worker) in Pogonomyrmex californicus revealed significant stage‐specific differences in Gene Body Methylated frequencies. Methylation sites were highly correlated between WGBS and ONT in P. californicus Genome‐wide methylation was low (~3%) and highly clustered within gene bodies (GBM), especially
