Girl scouts, parents and scout leaders investigated pest management and agricultural careers at the GIRL Expo organized by Girl Scouts of Central California South on January 24, 2015. The annual scouting event attracts more than 1,200 visitors from Fresno, Kern, Kings, Madera and Tulare counties for a day of “learning by doing” and inspiring girls to take action for their planet and their communities.
Roberta Barton and Julie Sievert represented UC ANR Kearney Agricultural, West Side and Lindcove Research and Extension Centers at an interactive information booth in the “CSI” area. In keeping with the crime scene investigation theme, different “crop science investigation” dioramas were presented containing clues to common pests and pest management methods. Girls and adults had fun using their powers of observation and child-sized magnifying glasses to identify the usual “suspect” for each scene from among a gallery of “wanted” mug shot posters for aphid, rodent, weed, Asian citrus psyllid, snail, and slug pests. Curious visitors were drawn to the REC booth to participate in the engaging hands-on learning activity, get seed packets, and have a chance to win a California Naturalist bug observation kit.

The UC Statewide IPM Program provides new resources to help workers identify the light brown apple moth.
Nursery workers are our first line of defense in detecting light brown apple moth when growing ornamental plants in commercial nurseries. A new brochure and video can help those in the field distinguish light brown apple moth from several look-alike caterpillars.
Light brown apple moth is currently under a California Department of Food and Agriculture quarantine that regulates the interstate shipment of plants to keep the moth from spreading to new areas. It has been quarantined in various counties throughout coastal California ranging from Mendocino to San Diego.
Correct field identification of the light brown apple moth is the first step in containing the spread of this moth. Unfortunately several other leafroller caterpillars, including the orange tortrix, omnivorous leafroller, avocado leafroller, and apple pandemic moth, look similar to light brown apple moth caterpillars. This makes photo identification tools that can go into the field with workers, like the Field Identification Guide for Light Brown Apple Moth in California Nurseries, a useful resource for nursery workers.
The field guide was created by Steven Tjosvold, Neal Murray, University of California Cooperative Extension; Marc Epstein, Obediah Sage, California Department of Food and Agriculture; and Todd Gilligan, Colorado State University with the Statewide Integrated Pest Management Program (UC IPM).
An exotic and invasive pest from Australia, light brown apple moth has a host range of more than two thousand plants. It is a pest to a wide range of ornamental and agricultural crops, including caneberries, strawberries, citrus, stone fruit, apples, and grapes. The caterpillars eat leaves and buds, leading to weak or disfigured plants. They also can feed directly on fruit, causing the fruit to be unmarketable.
For more information on light brown apple moth and other leafrollers found in nurseries, see the UC Pest Management Guidelines for Floriculture and Nurseries.
