Horticulture Q and A from the Mojave Desert
Omg I can't believe I came across this article! I have these bugs in my garden, and haven't been able to find out what they are. And they do travel in tandem like that. Apparently they are stopping for some fun in Vegas, going from Yuma to the Coachella Valley! They are mostly in my flower garden, living in my bark mulch. Could they have come in from that? I'm not growing any of the vegetables in the article, but will be in a couple of weeks. I'm glad I came across your blog address in the The Veiw newspaper. Thanks!!
They are here in Los Alamitos, Orange County, CA June 2012 on my alyssum.This is an excellent photo of what they look like in their various maturities on my alyssum plants:http://cisr.ucr.edu/images/bagrada_bug/03_bagrada_bug_cisr.jpg
HELP! I need to know how to get rid of these pests! They are attacking my vegetables as soon as they sprout! It's been an ongoing problem I have for 3 years! I need to get rid of these beetles for the long term.
Research to date also suggests that heavy Bagrada bug infestation control with insecticides is the most economically viable option to protecting stands and preventing significant yield losses,” Palumbo said. This includes chemigation with pyrethroids, and using contact insecticides (pyrethroids, Lannate, Lorsban) once plants emerge and the irrigation pipe is pulled. After stands are established and plant size increases up to the 3-4 leaf stage, or on growing transplants, PCAs may consider alternating to dinotefuron (Venom/Scorpion) to protect plants from Bagrada feeding. This neonicotinoid also provides knockdown of whitefly adults and nymphs.This was taken from the Western Farm Press article and talking about Univ of Arizona trials and research.http://westernfarmpress.com/vegetables/finding-solutions-bagrada-bug-control-west
