#ObservationOfTheDay

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

My personal favourite is : "New insights revealed by $place here your last fancy method$". Generally the sign of a not so interesting paper with AI text generation involved

📢 1/6 Our latest paper is out in @PLOSONE!
We investigate how to improve trapping of jewel beetles, crucial for early detection of non-native species. 🌳🪲Brief summary in this thread ⤵️

Attended the #Cecidomyiidae meeting organised by @iteipmai a few weeks ago in Avignon
🪰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)🐞📸

We analyzed how Members of the European Parliament voted on 12 key votes concerning #pollinators policies. Check our interactive dashboard developed with #rstats #flexdashboard:See also @BeeLifeEU MEPs Scoreboard :

How reliable is the identification of pollen by #metabarcoding ? 🌼 How to improve the accuracy of these identifications? We explore these questions in our last paper @peerJ#Bioinformatics #Pollinators Brief summary in this thread ⤵️

📊Nice visual summary of my #iNaturalist 2023 stats. 🦠
First highlight: a Demodex mite found living on my nose - don't be jealous, they're probably crawling on yours too! 😅

🐝 We released the results of #COLOSS survey for #HoneyBee winter mortality in Belgium as an interactive dashboard. 😢17% of colonies lost last winter❄️

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! 📈🌿

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. Best practices for data collection

📊 I gave a seminar on best practices for data collection

Learn which data / metadata to collect systematically & tips to avoid hours of data cleaning nightmare 😅(aka 80% of data scientist's job😭)

But why on earth are they called "longhorn beetles"? I wonder... 🪲🦌 #cerambycidae #monochamus #coleoptera #macrophotography

🌲🔍 Non-European #BarkBeetle Pityophthorus solus spotted in the wild in Belgium (found previously in Spain & Hawaii outside its native range).🙏Thanks to T.Atkinson,& other #scolytinae experts for ID help.

🪲🪵Wood borers spotted during @IUFROdivision7 conference in Bordeaux:
1️⃣Monochamus galloprovincialis, gorgeous #Cerambycidae but vector of the Pine wood nematode😱
2️⃣Six-toothed #BarkBeetle, Ips sexdentatus. Smaller but very harmful🌲
3️⃣Ergates faber: Beware of its mandibles!🪚

At the @IUFROdivision7 conference on bark and wood borers in Bordeaux. @Alex_Kuhn presented our work on Ips typographus management. 🪲Very interesting talks, super nice people and the occasion to look for insects in the urban environment (found Coccoidea 😍

🌲🪲When a #BarkBeetle challenges Donald Trump's hairstyle... Or is it more BoJo? These female Pityokteines spinidens are amazing anyway💃🔥! Fancy more diversity of bark beetle heads and butts? Check out @JiriHulcr and @MarcAbrahams' fantastic book

🪲Can #pheromone traps really make a difference against the spruce #BarkBeetle (Ips typographus)?🌲 Our 2-year experimental study reveals some surprising insights🔬!

😍Holidays in Italy: met rare ladybird Ceratomegilla rufocincta🐞! Waited 15 years to meet this endemic from the Southern Alps. Spotted its buddies too: C.alpina and C.notata. Documented lifecycle through rearing & 📸.

🌼🐝 Curious about bees' favourite flowers for collecting pollen? #Metabarcoding is the way to go. But first, you’ll need a sturdy DNA reference database🧬Find out how we build such databases at CRA-W in our recent paper #bioinformaticsvia @BioMedCentral
