Tridge summary

A study published in the journal Science of the Total Environment predicts that rising temperatures due to climate change will lead to an increase in populations of three major insect pests in California - codling moth, peach twig borer, and oriental fruit moth. These pests are particularly damaging to walnut, almond, and peach orchards, which could have a significant economic impact on the state's specialty crops industry. The study suggests that growers may need to adapt their pest management strategies to address the growing threat posed by these pests, including using pest-resistant crop varieties and implementing biological control methods.

As a result of climate change, the Golden State's farms are expected to face a surge in agricultural pests, which poses a threat to California's specialty crops industry. Populations of three major insect pests—codling moth, peach twig borer and oriental fruit moth—are projected to increase mainly due to rising temperatures, according to a study published in the journal Science of the Total Environment by a team of researchers at UC Merced, University of California Agriculture and Natural Resources and the U.S. Department of Agriculture California Climate Hub. "These three pests are notorious for infesting most of the walnut, almond and peach orchards of California, causing extensive damages by reducing quality of fruits and nuts," said study co-author Jhalendra Rijal, UC Cooperative Extension integrated pest management advisor and entomologist for Stanislaus, San Joaquin and Merced counties. Climate change can ...
