2012 Persea Mite Workshop

Workshop title, dates

Workshop Details

Who: This workshop is designed for the CA avocado community (growers, researchers, pest control advisers, farm advisers, orchard employees, packing house employees, grove managers, etc.)

What: A hands-on workshop to learn about avocado mites and their control

Santa Paula (June 20), Hansen Ag Center, 14292 West Telegraph Road, Santa Paula, CA 93060 (Please park in the parking lot on Briggs Road)

Irvine (June 27), South Coast Research Experiment Station, 7601 Irvine Blvd, Irvine, CA 92618

When: Two sessions held at each location, Morning (8-11:30am) & Afternoon (1-4:30pm). Both sessions cover the same material.

Arrive within 15 minutes of the listed time for the workshop session you selected. This will allow for you to find parking, sign in and fill out your form for Continuing Education (CE) Credit (2.5 hours).

Why: There are beneficial and pest mites in the CA avocado system. Learning how to recognize, monitor and control pests is an important part of successful orchard production.

Workshop Description:

The persea mite (Oligonychus perseae) is a non-native leaf-feeding pest of avocado trees in California. The feeding damage caused by this mite has been recently linked with yield reduction. This training workshop contains a presentation and field demonstration with updated information on persea mite research and pest management for the California avocado system.

Participants will learn:

  1. How to recognize beneficial and pest mites from avocado trees
  2. The basics of persea mite biology, invasion history and management options (i.e., biological control and pesticide recommendations)
  3. In the field demonstration, participants will get hands-on experience on how to use two simple sampling methods designed to estimate persea mite densities in commercial avocado orchards

Mark HoddleDr. Hoddle has headed the research in this laboratory since 1997 and is primarily involved in the identification of pest problems where biological control could be a successful approach. The location, release and evaluation of natural enemy impacts on population growth features strongly in his research. The evaluation of biological control agents are conducted primarily in the field and, when necessary, aspects of both pest and natural enemy biology and behavior are studied in the laboratory.

Ricky LaraRicky joined the Hoddle laboratory in 2008 as a graduate student pursuing a Ph.D. in Entomology. His academic interests revolve around acarology, agroecology and integrated management of economically important pests in agriculture. This committed appreciation of acarology began with several undergraduate internships working in California vineyards. More info...

Tom RobertsTom Roberts is an independent pest control adviser with a focus on avocados, citrus and grapes. He works in Ventura, Santa Barbara and San Luis Obispo Counties. 

Ben FaberDr. Ben Faber is the soils-water-subtropical crops advisor for Ventura and Santa Barbara Counties. His primary crop involvements are avocado and citrus. He is currently evaluating various subtropical tree varieties for their economic viability in coastal environments. He also studies soil and water quality issues (e.g., irrigation scheduling, erosion, salinity, orchard floor & fertility management). More info...

Gary BenderDr. Gary Bender is a farm adviser in Southern California. He specializes in subtropical horticulture; deciduous fruit trees; irrigation; water quality; pest management; root rot and pathology of avocados and citrus; and avocado canopy management. More info...
