Starting off here with a last spring snapshot of Sitodiplosis mosellana—the orange wheat blossom midge. This #cecidomyiidae may not form #galls, but it’s a major pest of cereals 🌾. #diptera #entomology

🪰Gall midges cause trouble in lavender there and in other plantations in Europe (pears, cabbages, douglas firs,...)
Great people, strange maggots and ladybirds in action (I couldn't resist)🐞📸

In our ongoing experiment, we are exposing Douglas firs 🌲 to varying densities of the #invasive gall midge Contarinia pseudotsugae 🪰 within insect-proof tunnels and measuring the impact on tree growth. Measurements in progress, results coming soon! 📈🌿

Best practices for data collection
In this online training session you’ll learn:
- Best practices for data collection and common mistakes to avoid
- Which information should be collected?
- What can be done with spreadsheets and CSV files?
- Why metadata is important?
- How to organize the datasets and metadata?
You can access the pdf version of the presentation here: https://8e8ea45e-d3b1-4c0f-8009-56b8df6908d2.usrfiles.com/ugd/8e8ea4_f98a6a988b5942f99ff1a6082e927ce3.pdf
This online session is organised by BeeLife European Beekeeping Coordination and the Walloon Agricultural Research Center (CRA-W) within the framework of the EUBP Platform project.
