Have you seen aphid mummies and wondered "what's going on inside?" Here's a pea aphid that has been mummified (dried/swollen) by the braconid parasitoid Aphidius ervi, right next to its unsuspecting compatriot. The chunky wasp larvae is moving inside the remaining aphid "husk."

Sound on! Only two miles from the house, beautiful sunset and geese moving around the valley this winter. Lucked out this flock flew directly at/over me after they got up several miles away.

Our dept. is recruiting an "Assistant Professor of Insect Biology"! The position description is broad: "We define insect biology in the broadest sense." First review date is Dec. 1. See link for additional details. recruit.ucdavis.edu/JPF05990 beetles : ucdavisentgrad.square.site

@DSKarp @saraeemery No, but that would be great! @saraeemery let me know if you'd like to chat at some point.

Still time to plan on coming to our cotton meeting! DPR CE credits approved. Message with any questions.

Easter egg time. I put a little surprise in this metal bug (thank you for all the ♥️)...it has gears, and so do real bugs! So planthoppers...hop on plants. To make sure both their tiny legs jump simultaneously, they have GEARS BETWEEN THEIR LEGS. 1/2 paperpile.com/shared/IkGYt4

See #CArice fields seeded at 100 MPH! Many benefit from every field planted in the #SacValley including businesses, communities and wildlife.

@chdiep Thanks, glad that “did something” for you. Trying to mix things up a little!

Jr. Specialist position (UCD) still open through tomorrow (4/14) for the 1st review (recruit.ucdavis.edu/JPF05603). Limited to people with a Bachelor's. It's for one year, assisting on a variety of projects in field and veg crops. Easy app, share with anyone that would be a good fit.

Echoing this from my own account too! Hopefully folks enjoyed seeing the beasties (tadpole shrimp) up close. I WAS told “they actually are kind of cute”.

Mostly clear skies on Wed provided an excellent view of the lower Sac River's flood control measures. #CAwx #CAwater Photo 1📷| Sutter Bypass ends at the Sac River, spills over Fremont Weir & into the Yolo Bypass. Photo 2 📷|✨Zoom, enhance✨ 🛰️Sentinel-2/European Spacy Agency

Amazing footage but horrible to see. Looks like a view over this area: maps.app.goo.gl/Nvxwbv3dm3T5Rv…

I’ve stood near this same corner on the west side of the Gonzales river bridge everyday this week and today the Salinas river is now flowing over the road, turning the nearby ag field into a lake..

The Tisdale Weir across the Sacramento River from 108 is now running. Several Weirs and Bypasses along the river provide relief during high water levels by rerouting excess water.

Thrips and INSV remain a major problem for lettuce production in the Salinas Valley of CA. I have two @USDA_ARS postdoc positions available immediately to develop diagnostic and management tools! If you’re at #EntSoc22 say 👋🏼 ksbw.com/article/pathog…

Do it!

@AttardoGeoff Ooooo, going to have to chat with you. I need to get some new equipment and see a few things I am going to get. Curious to see what you I went with overall.

My new toys came in! We're gonna take some pretty pictures of vectors! Will make them available for one and all.

We have a new position available in the Department of Entomology and Nematology at UC Davis for an Assistant Professor of Teaching (LPSOE)! Come join our wonderful faculty to help instruct the next generation of Entomologists! Apply here - recruit.ucdavis.edu/JPF05348

@DominicDReisig Missed all of the good info and discussions plus seeing folks! Life of two academics plus a toddler…

@IGrett Missed you in Tucson

Our lygus trial in cotton is looking pretty good as we finish off the season. Challenging pest in CA cotton, so more tools are always needed.
