Help increase public awareness of invasive species and encourage participation in the ongoing fight against invasive species by celebrating California Invasive Species Action Week (CISAW) June 1- 9, 2024.

Invasive species include non-native plants, animals, and pathogens that can negatively impact our waters, native ecosystems, agriculture, health, and economy. Every day this week, UC IPM will share information spotlighting a different invasive species, its impacts, and what you can do to help.

Keep an eye out for our upcoming blog posts and check out the resources below to learn more about invasive species:

Healthy Soils Week (Dec. 4-8) is a week-long initiative by the California Department of Food and Agriculture (CDFA) to highlight the importance of soil health throughout California. 

Healthy soils can improve crop yields, sequester carbon, reduce erosion, and increase biodiversity. In addition, they can reduce pest problems and pesticide and fertilizer use. Healthy soils lead to healthy plants which are less susceptible to pest attacks and can better tolerate and recover from pest pressure.

In integrated pest management (IPM) we promote the use of cultural control methods to improve soil and plant health, making an environment less conducive for pests to...

Seven invasive fruit fly quarantines are in place throughout California. If you live within one of these quarantine zones, fruits and vegetables should not be moved off the property they were grown on. Quarantines are in place for the Mediterranean fruit fly, Oriental fruit fly, tau fruit fly, and Queensland fruit fly. Smuggled, illegally imported fruit is the most common pathway of fruit fly entry into California.

These fruit flies lay their eggs under the skin of many crops, making their detection difficult. Females of some species can lay 1,000 eggs in their lifetime. Once eggs hatch, larvae (maggots) feed on the inside of the fruit. Infested fruit drops to the ground where larvae leave the fruit to burrow into the soil to...

QFF quarantine in LA, Ventura counties among seven fruit fly quarantines statewide

Residents in multiple Southern California and Northern California counties should not move homegrown fruits and vegetables from their properties to help contain several species of fruit fly that can destroy crops and impact the livelihoods of local farmers.

With sharing and gifting of food integral to the holiday season, the California Department of Food and Agriculture is reminding people to heed the seven active fruit fly quarantines aimed at controlling the
