Alameda County Department of Agriculture, Weights and Measures is involved in a continuing insect pest detection program. This is part of a statewide cooperative effort to protect California's agriculture from unwanted pests.

Insect detection traps are often placed in residential yards and gardens. We have an ongoing survey to locate desirable host trees and plants to in which to place insect. These pests are host-specific; therefore it is crucial to place traps in the best host location in order to increase our chances of early detection. Traps are relocated on a regular basis throughout the county and generally stay at a location for approximately two months.

Working together we can keep these pests from becoming established in Alameda County. You can help by allowing Agriculture employees access to your property to install and monitor insect survey traps.

We are currently looking for the following host plants:

Apple, Apricot, Asian Pear, Avocado, Beans, Calamondin, Catalina Cherry, Cherry, Crepe Myrtle, Cucumber, Fig, Grapefruit, Guava, Kumquat, Lemon, Loquat, Melons, Nectarine, Orange, Peach, Pear, Peppers, Persimmon, Plum, Pomegranate, Pumpkin, Quince, Roses & Turf, Sapote, Squash, Tangerine, Tangelo, and Tomato.

If you have any of the host plants listed above on your property and you would like to help:
