This is the fourth in a series featuring a few scientists whose work exemplifies UC ANR's public value for California.
UC Cooperative Extension entomology advisor David Haviland has been recognized by his peers, his clientele, and extension directors who oversee programs in 14 western U.S. states. It's a Cooperative Extension hat trick unusual among UCCE mid-career professionals.
“The combination of three awards for me is an incredible honor because I know there are a lot of good extension programs out there,” Haviland said.
In July 2019, Haviland accepted an
San Joaquin Valley farmers are facing an unusually high pest population this spring due to the milder than normal winter, and rapidly warming spring conditions, says a UC Agriculture and Natural Resources entomologist.
“I've never seen this happen before in the 25 years I've been working on citrus entomology,” said Beth Grafton-Cardwell, UC ANR Cooperative Extension citrus entomology specialist. “One pest control adviser who's been in the business for 50 years told me this is the first time he's seen weather conditions this extreme.”
In a normal valley winter, temperatures dip into the low 20-30s for weeks at a time. But...

It's cherry growing season and a good time to begin looking for spotted wing drosophila (SWD), Drosophila suzukii. SWD is a small fruit fly that attacks soft-flesh fruit such as cherry, blueberry, raspberry and blackberry. It first appeared in 2010, and its damage to fruit and increased management costs led to significant economic losses to cherry growers throughout California and the Pacific Northwest.
Unlike other fruit flies that infest rotted fruit, SWD attacks undamaged fruit. As cherry fruit begins to develop and starts to change color from light green to straw, SWD lays its eggs just under the skin of fruit, creating a small scar or...
