For anyone wondering where modern #chemicalecology stands, here is an instant classic example 🤩
Small changes in the olfactory receptors of Drosophila suzukii agricultural pest explain its preference for laying eggs in ripe fruit instead of overripe fruit bc of detection of ester fruit volatiles 🤯
Here is Petra testing her bee 🐝 cage experiment to assess biomiticide peptide against varroa mites as an alternative to chemical pesticides 🤩 Thanks to Project Apis m. for the support!

The International Society of Chemical Ecology Conference will be hosted by Cornell (Ithaca, NY) this June 21-26! 🐛🧪🥀🦠🦇
Early Bird registration until April 7! Please spread the word!
Lots of great talks and sessions! Post-conference Metabolomics Workshop!

Well deserved!!!
My first podcast 😅 on how decoding the smell of organisms could help us to find solutions to protect crops in agriculture, and improve plant, animal, and human health by detecting diseases before symptoms appear!

Our most accomplished work on chemical evolution 🥳
These N,S-cardeneolides have unique structures and bioactivities, and they also have divergent macroevolutionary histories 🤩

Here is the Cornell Chronicle article about our PNAS paper on the evolution of milkweed toxins (N,S-cardenolides), to which the monarch butterfly is sensitive, despite being co-evolved with milkweeds!

Ever wondered how the #cuticle, a hallmark of land plants, was established?
In our latest study, we show that the CUTIN SYNTHASE enzyme family was a key driver of this evolutionary innovation. #plantscience

Our paper on using #eDNA from rainwater to study hidden biodiversity in #tropical #forest #canopies is now out in Science Advances! This method is a major step forward for the study and #conservation of this inaccessible compartiment. www.science.org/doi/10.1126/...

Milkweed has found a new strategy in its epic evolutionary battle with monarch butterflies: structurally upgrading its toxins to outmaneuver monarchs' resistance.
I am very happy to share that the latest work from the lab, led by Dr. Qi Xue, has been published in PNAS and is now online: www.pnas.org/doi/10.1073/...
