Bagrada Found in Eastern Fresno County
By Patrick Cavanaugh, Editor
Michael Yang, a UC
Cooperative Extension Fresno County ag assistant specializing in small farms
operated by Hmong Farmers, said a farmer who had a mustard plant infested with
a bug called him out. “The farmer in Eastern Fresno County wanted to know what
he could spray to kill the bugs,” Yang said.
He said that hundreds of the insects
were infesting the mustard plant—a favored host of the pest.
“I did some research and it
looked like the pest was the Bagrada bug. So, we we bagged part of the plant
with the bugs and sent them to the Fresno County’s Ag Commissioner office. They forwarded the sample to the CDFA in Sacramento, and CDFA confirmed that it was the Bagrada bug,” said Yang.

Yang noted the low rainfall
this year left the foothills dry and many insects started coming into the lush
fields grown by Asian famers.
According to UC IPM, Bagrada
bug, Bagrada hilaris, is an invasive stinkbug spreading through western
Arizona and southern California since 2008, causing severe crop, nursery, and
landscape losses. Bagrada bugs gather on plants in large groups. In
agriculture, Bagrada bug is a pest of cole crops and other mustard family
Growers are asked to alert
their county UC Farm Advisor if they see Bagrada bugs in their fields, as it is
a new pest in Fresno County. The pest has been widely observed in southern
California Counties and more recently in Monterey County.
There are several pest
control products that are registered and effective on the pest. Growers should
contact their pest control advisor for advice.
