Shoutout to Entomology PhD student Sylvana Ross for her recent feature in the Cornell Chronicle! In the article, she shares insights into her projects and how her research journey began, highlighting the value of engaging communities in urban ecology and shedding light on the diverse insect life thriving in our cities. 🐞🌱 Ross’ research is among the first to examine how the historical structuring of cities affects biodiversity, offering new insights into the relationship between urban development and ecological communities.

The annual Bee Course recently wrapped up in southeastern Arizona! Dr. Bryan Danforth, along with former Cornell students and post-docs and collaborators from other institutions, led the course, which is administered through the American Museum of Natural History and hosted at the in Portal, AZ. The course this year included 24 students from the US, Canada, Ecuador, Uruguay, Panama, Sri Lanka, and Israel, representing a wide range of backgrounds—from academic institutions, conservation organizations, and federal and state agencies. The course focuses on the biology, systematics, ecology, and natural history of bees. The Chihuahuan desert is a bee biodiversity hotspot, and therefore an ideal location for engaging students in the diversity of bees. Thanks to everyone who contributed to and participated in the Bee Course this year, and to the SWRS for hosting us! For more information on the Bee Course, see our website. Link below:

Protecting crops and pollinators takes teamwork. 🌻🐝 Cornell Department of Entomology researchers and Cornell Integrated Pest Management are working with New York growers to address the challenges and opportunities created by the state's new pesticide ban. Read more:

Preliminary Cornell research on managing the dreaded seedcorn maggot is giving hope to growers across the state ahead of New York’s 2029 ban on neonicotinoid pesticides in field crops: Side-by-side farm trials of neonic-treated vs. untreated corn showed no difference in yield.

Thank you to everyone who stopped by the Dyce Lab for our 2026 honey extraction! 🍯🐝 It was great to connect, share our excitement for bees (and birds!), and send everyone home with a sweet treat to welcome the fall semester. We look forward to seeing you again soon!
Below are the numbers for this year:

Number of participants: ~550
Youngest participant: 8 weeks old (unless I missed someone younger!)
Furthest travelled to get to Dyce: Busan, South Korea
Most enthusiastic participant: James the dog (as usual)
Total honey extracted: ~156 gallons (1872 lbs)
Taken home by wonderfully helpful participants (thank you!): ~130 gallons (1560 lbs)
Consumed by the most enthusiastic participant: Not too much this year! But there’s still some cleaning to do...🐝

🦟 Today, August 20, is World Mosquito Day! Take a tour of the Murdock Lab Insectary and learn some fun facts about these tiny creatures and the important research being conducted, from caring for larvae to feeding adult mosquitoes. Special thanks to PhD student Brit Johnson for taking us behind the scenes.
What do we feed our mosquitoes?
Larvae are fed fish food pellets. Adult mosquitoes are fed blood. Depending on the species, this may be cow, chicken, or human blood obtained from a blood bank.

What do we study in our lab?
We investigate how environmental factors, such as temperature and humidity, affect mosquito fitness and their ability to transmit diseases like malaria and dengue.

How long do mosquitoes live?
It depends on the species and their environment. In the wild, mosquitoes typically live for 3 to 4 weeks. In the lab, they can survive for up to 60 days when provided with optimal conditions.

Before this summer, CCE intern Edmund Hod ’29 had never set foot in a cow or sheep pasture.

Weeks later, he was dragging fields for ticks, identifying dung beetles under a microscope, counting parasite eggs in sheep samples and doing fieldwork on his own.

The CALS entomology major spent the summer working with Cornell Cooperative Extension Albany County, the Hudson Valley Research Laboratory and Cornell IPM on livestock pest management research. Along the way, he helped monitor farms across the Capital Region and Hudson Valley, tested CO₂ traps for Asian longhorned ticks and created an information sheet for livestock producers.

There were also the less predictable parts — sheep that started recognizing him, a calf licking his hair and helping herd escaped cows across the road.

By the end, Edmund said he was surprised by just how much he had experienced and learned in nine weeks, and grateful for the chance to explore so many sides of entomology so early in his Cornell career.
