Researchers look at two parasitoids from Pakistan as potential natural pest control

The fruit orchards of California are under attack by Asian citrus psyllids (Diaphorina citri). These insect pests spread the huanglongbing disease that kills profitable citrus plants. To combat them, researchers are using two parasitoid wasps from Pakistan, the original home of the psyllid menace. The psyllids are an invasive species from southern Asia that first […]

Looking at alternative approaches to pest control

In response to the devastating huanglongbing disease sweeping through California’s citrus orchards, researchers are testing a biological control program. They are using two wasps from Asia that are natural enemies of the Asian citrus psyllid (Diaphorina citri), an invasive species of insect that spreads the bacteria responsible for the disease. The study was supported by the University of California Riverside. […]

Conservationists looking at fungi to restore native plant populations

More than five million species of fungi have been identified so far, but only about 300 are known to make people sick. Fungi – both the “good” and the “bad” ones – play a vital role in the ecosystem, something that conservationists from Washington State University Tri-Cities (WSU Tri-Cities) are demonstrating through their research. Tanya […]
