Highlights from the latest issue of “Topics in Subtropics” cover several developments and research updates relevant to California’s subtropical agriculture sector. The publication includes information on citrus integrated pest management (IPM) entomology, avocado flowering and fruit set, woodpecker damage in avocados, and the expansion of pest control district services.
