In a ground-breaking discovery encompassing six years of research, an international team of scientists led by UC Davis chemical ecologist Walter Leal announced they've identified the sex pheromone of the Asian citrus psyllid (ACP), an insect that feeds on citrus and transmits the bacteria that causes the deadly citrus greening disease known as Huanglongbing (HLB).
Leal's team included scientists from UC Davis, University of Sao Paulo, and the Fund for Citrus Protection (FUNDECITRUS) from the state of Sao Paulo.
“Dr. Leal's discovery of the ACP pheromone is a significant breakthrough in preventing the spread of this serious citrus insect,...

HLB, also known as citrus greening, has already devastated the citrus trees in Florida, Georgia, Louisiana, South Carolina, and Texas. There is no known treatment for the disease, which usually kills the tree within three to five.../span>
If you subscribe to our Pests in the Landscape blog, you'll notice that we frequently post updates about Asian citrus psyllid (ACP) and huanglongbing (HLB). Educate yourself about ACP and HLB so you can help prevent its spread. Here are a few things you can do:
Attend one of two Northern California Retail Nursery and Garden Center IPM Workshops this January!
UC IPM is offering two hands-on, train-the-trainer workshops designed especially for retail nursery and garden center employees, managers, owners, and affiliates.
