UV‐Induced Fluorescence in the Balance: Mate Choice and Predation Risk in the Female Ornamented Jumping Spiders

open access: yesIntegrative Zoology, EarlyView.
This study investigates the potential adaptive advantages of female‐specific UV‐induced fluorescence in male mate‐choice and predation risk, as fitness costs, using two species of ornate jumping spiders Phintella vittata and Ph. bifurcilinea. Our findings provide empirical evidence of a trade‐off: While fluorescence enhances male mate preference, it ...

Genetic modification of the ant Lasius niger using CRISPR‐Cas9 technology

open access: yesInsect Molecular Biology, Volume 32, Issue 1, Page 11-25, February 2023., 2023
We successfully modified the cinnabar gene in the black garden ant (Lasius niger) resulting in an abnormal eye colour in mutated adults. We provide a detailed protocol to collect ant eggs, inject them with CRISPR‐Cas9 construct, rear the eggs to adults and verify mutants by sequencing the target gene.

Understanding the impact of host plant factors on the oviposition behaviour of the cabbage stem flea beetle (Psylliodes chrysocephala)

open access: yesAnnals of Applied Biology, EarlyView.
The cabbage stem flea beetle (Psylliodes chrysocephala) is an important pest of oilseed rape (Brassica napus) in Europe. The objective of the present study was to gain a better understanding of host plant related factors affecting its oviposition behaviour with the aim of developing new sustainable control strategies.

Dietary Zinc Limitation Dictates Lifespan and Reproduction Trade‐Offs of Drosophila Mothers

open access: yesAging Cell, EarlyView.
Dietary metal ions significantly influence the lifespan and reproduction of Drosophila females. In this study, we show that not adding any of the metal ions to the diet adversely affects reproduction and lifespan. By contrast, food with no added Zn negatively impacts reproduction but not maternal lifespan, suggesting that female flies stop producing ...
