Honey bees, mosquitoes, cabbage butterflies, fruit flies and more...

You'll hear about a variety of insects when the international symposium, “Insect Olfaction and Taste in 24 Hours Around the Globe,” takes place beginning at 9 a.m., Pacific Daylight Time (PDT), Wednesday, Aug. 11. 

The 24-hour Zoom symposium has already drawn more than 1100 registrants from 66 countries, according to UC Davis distinguished professor Walter Leal, one of the three co-hosts. It's free and open to all interested persons. You can register at https://bit.ly/3k68c2m. 

The speakers will focus on a wide variety of insects, including three species of mosquitoes (Culex, Aedes and Anopheles); honey bee (Apis mellifera); fruit flies (Drosophila melanogaster, Drosophila sechellia, and Drosophila suzukii); sand flies (the blood-sucking dipteran flies); cotton bollworm (Helicoverpa armigera); housefly (Musca domestica); cabbage butterfly (Pieris rapae); and the American cockroach (Periplaneta americana). 

The event will cover such topics as why mosquitoes are so persistent; the origins of insect olfaction; bitter perspectives (and insect taste); and novelty detection in the early olfactory processing of the honey bee. 

“We will have 15 invited (keynote) and 36 contribution presentations,” said Leal, who will host the PDT segment. One of the interviews will feature olfaction research pioneer Karl-Ernst Kaissling of Germany. 

Co-hosts with Leal are Wynand van der Goes van Naters of Cardiff University, UK, who will host the British Summer Time (BST) segment; and Coral Warr of La Trobe University, Australia (formerly of the University of Tasmania), host of the Australia Eastern Standard Time (AEST) segment.  The trio, along with Karen Menuz (PDT), Wei Xu (AEST), and Emmanuelle Jacquin-Joly (BST), will moderate the symposium. 

The speakers include icons in the field as well as graduate students, postdoctoral fellows, early career professionals, and under-represented minorities. Of  the 15 keynote lectures, seven will be delivered by woman scientists.  

“The attendees will be engaged by questions and answers,” announced Leal, a UC Davis distinguished professor with the Department of Molecular and Cellular Biology and a former chair of the Department of Entomology (now the Department of Entomology and Nematology). “We will give priority to questions from students, postdocs, and early career professionals, but will attempt to address everyone's questions. Attendees can ask anonymous questions.” Many of the attendees would not otherwise have an opportunity to travel to an international symposium, he added. 

The first segment--the PDT segment hosted by Leal--begins with a welcoming address by John Hildebrand of the University of Arizona, Foreign Secretary of the National Academy of Sciences. Presentations by Josefina del Marmol of The Rockefeller University, New York,  and Jon Clardy of Harvard Medical School will follow.  “There will be four keynote lectures and 10 contributed presentations,” Leal said.  

The last presentation in this segment, by Ke Dong of Duke University, will bridge with the AEST segment, hosted by Warr. It will include two keynote lectures and 14 contributed presentations. Then, a keynote lecture by Richard Benton of the University of Laussanne will bridge with the BST segment, hosted by van der Goes van Naters.  It will include six keynote lectures and 12 contributed presentations. After the last lecture by John Pickett of Cardiff University) the symposium returns to UC Davis for closing remarks. 

One of the keynote speakers in the PDT segment is Zain Syed of the University of Kentucky, a former postdoctoral researcher in the Leal lab at UC Davis.
