What’s attacking your landscape? Read all about it in the newly released book from UC ANR

What do Asian citrus psyllids, Bagrada bugs, brown marmorated stink bugs, palm weevils, and polyphagous shothole borers have in common? Not only are they invasive pests relatively new to California, but they have also been added to the newly revised ANR publication, Pests of Landscape Trees and Shrubs.

Now in its third edition, this integrated pest management (IPM) how-to guide is a comprehensive resource for arborists, home gardeners, landscapers, parks and ground managers, and retail nurseries. It contains solutions for hundreds of insects, mites, nematodes, plant disorders and diseases, and weeds that can damage California landscapes.

Dozens of pests new to this edition include those affecting azaleas, camellias, camphor, eucalyptus, hibiscus, liquidambar, maples, oaks, olive, palms, pines, roses and sycamores.

A very important part of pest management is designing a pest-tolerant landscape, choosing the right plants for the location, and maintaining the landscape with appropriate irrigation, fertilizer, and other cultural practices to keep plants healthy.

These practices are featured along with information on how to:

  • prevent pest problems and plant damage
  • monitor for pests efficiently
  • conserve natural enemies to provide biological control, and
  • selectively use pesticides in ways that minimize adverse impacts

A sampling of pages in Pests of Landscape Trees and Shrubs.
Presenting the practical experience and research-based advice of more than 100 University of California experts and landscape professionals, this 437-page book includes more than 600 high-quality color photographs and line drawings to help you recognize important pests and key natural enemies, causes and symptoms of plant damage, and pest biology and control techniques.

Problem-Solving Tables include the specific pests for each of over 200 genera of trees and shrubs, referring to the pages with their photographs and management solutions.

Pests of Landscape Trees and Shrubs: An Integrated Pest Management Guide, Third Edition, can be ordered through the ANR catalog. For more information, see the UC IPM website.

Bagrada bug menacing Santa Barbara gardeners and farmers

Seemingly out of nowhere, thousands of bagrada bugs have descended on Santa Barbara County gardens and organic farms, reported Joan Bolton in Noozhawk.

Bagrada bugs are native to east and southern Africa, Egypt, Zaire and Senegal, according to the Center for Invasive Species Research at UC Riverside. They first appeared four years ago in Los Angeles County, and rapidly spread through Southern California and southern Arizona.

Surendra Dara, UC Cooperative Extension advisor in Santa Barbara and San Luis Obispo counties, first wrote about bagrada bugs in his Strawberries and Vegetables Blog last January, when the pest was only found in Imperial, Riverside and Orange counties. Last month, Dara said the Santa Barbara agricultural commissioner received specimens from Solvang and found infestations of bagrada bug on mustard in other areas, making an official record of this pest in the county.

Conventional farmers are controlling bagrada bugs with pyrethroids and organophosphates like chlorpyrifos and malathion. However, because the bugs are so new to scientists, they haven’t yet figured out much in the way of organic controls, Dara said.
