University of California Agriculture and Natural Resources announced on April 15 that it will begin its seasonal updates on thrips development, noting ongoing technical issues with the UC ANR web platform. The organization said updates will be reported through alternative channels for the start of the season.
The timing of these reports is important for growers monitoring pest activity in their crops. According to the update, “The first post winter generation adults peaked around March 18th (about 2 weeks earlier than 2025). Peak egg hatch for generation 2 peaked around April 4th. Generation 2 adults will peak around April 24th. Based on current development rates and projected temperatures, the third generation of adults should peak around May 25th.” The report added, “Unless there is evidence of TSWV in crops already, it is unlikely that treatment for thrips will be useful at this time until the third generation at the earliest.”
University of California Agriculture and Natural Resources secures funding through public contributions to support its programs, according to the official website. The organization promotes sustainable practices aimed at strengthening resilient ecosystems and economic vitality according to its official website.
The university uses nine research and extension centers as laboratories representing California’s diverse ecosystems according to its official website. It has also gained recognition for providing trusted services that link research with community needs according to its official website.
As part of the University of California system, UC ANR manages Cooperative Extension services throughout California according to its official website. Each year, it conducts more than thirty-three thousand educational events and engages over eighteen thousand volunteers in various initiatives according to its official website.
These seasonal updates are expected to continue as conditions develop further into spring.
