Should I stay or should I go? Modelling dispersal strategies in saproxylic insects based on pheromone capture and radio telemetry: a case study on the threatened hermit beetle Osmoderma eremita
TLDR
A novel, multi-pronged approach to study dispersal strategies in the endangered saproxylic hermit beetle Osmoderma eremita, exploiting its pheromone system to intercept high numbers of dispersing individuals, which is not possible with other methods.
Chemistry and geographic variation of floral scent in Yucca filamentosa (Agavaceae).
TLDR
No differentiation in floral scent was observed between populations pollinated by different yucca moths, nor was there any correlation between chemical distance and geographic distance among populations, so the observed lack of differentiation can putatively explain high moth-mediated gene flow among sites, but it does not explain conservation of odor composition across populations with different pollinators.

TLDR
It is suggested that around 1900 individuals, or at least half of the O. eremita population, may perform flights from their natal host trees, representing higher dispersal rates than previous estimates, and demonstrates that pheromone‐based monitoring is a valuable tool in the study of species or life‐history stages that would otherwise be inaccessible.
Kairomonal Response of the Parasitoid, Bracon hebetor Say, to the Male-Produced Sex Pheromone of Its Host, the Greater Waxmoth, Galleria mellonella (L.)
TLDR
The results show that females of this economically important parasitoid utilize the male-produced sex pheromone of a host as an indirect cue to guide them to potential oviposition sites.
Monitoring presence, abundance and survival probability of the stag beetle, Lucanus cervus, using visual and odour-based capture methods: implications for conservation
TLDR
Collection of adult beetles, dead or alive, by VES is the most reliable way to monitor this emblematic species, and body size influences the survival probability of stag beetles, showing a lower survival probability for larger males.
Characteristic Odor of Osmoderma eremita Identified as a Male-Released Pheromone
TLDR
It is proposed that the strong signal from males is a sexually selected trait used to compete for females and matings, and could work within trees but also act as a guide to tree hollows, which are an essential resource for O. eremita.
The Successional Change of Hollow Oaks Affects their Suitability for an Inhabiting Beetle, Osmoderma eremita
TLDR
The presence/absence and population size of a threatened beetle, Osmoderma eremita, inhabiting hollow oaks, and the size of the largest entrance hole and tree diameter were positively correlated with the estimated wood mould volume, and could be used as easily measured proxies for wood mouldVolume.
Isolation by distance in saproxylic beetles may increase with niche specialization
TLDR
The results suggest that the dispersal ability of Osmoderma beetles may be one order of magnitude greater than suggested by previous dispersal studies and acceptable levels of habitat fragmentation for metapopulation survival may be bigger than previously thought.
Identification, Synthesis, and Behavioral Activity of 5,11-Dimethylpentacosane, A Novel Sex Pheromone Component of the Greater Wax Moth, Galleria Mellonella (L.)
TLDR
The identification of 5,11-dimethylpentacosane is an important step for the development of an efficient long-range attractant that will be integrated with other environmentally safe strategies to reduce damage to beehives caused by wax moths.
