Some pictures from 27th UCR Urban Pest Management Conference (March 21, 2018).
27th Annual UCR Urban Pest Management Conference was held at UCR Extension Center on March 21, 2018.
There were about 200 attendees from urban / structural pest management industry and other related parties, several industry sponsors, and 13 speakers from university labs, UC ANR, industry, government agencies. We think the conference was a big success.
This one-day conference has been UCR urban entomology program's one of the most important outreach events for professionals in the pest control management industry and the public interested in these questions. For more information, visit the following website.

Our research on the development of biodegradable hydrogel for delivering liquid baits to control Argentine ant was recently published in Pest Management Science.
Also, the journal chose the image from our research, showing Argentine ants feeding on the hydrogel bait, as the cover image for their October 2017 issue.

Scents from Bed Bugs' Shed Skin Affect the Pests' Behavior
Researchers find shed skins of bed bugs emit pheromones that could help combat infestations of the insect
RIVERSIDE, Calif. (www.ucr.edu) — Researchers at the University of California, Riverside have discovered the shed skins of bed bugs retain the “obnoxious sweetness” smell often associated with the pests, a finding that could potentially be used to combat infestations of the insects.
Bed bugs shed their skins, known as exuviae, as they grow. Four pheromone compounds known as aldehydes are consistently found in the shed skins.
