Cover Story: Laurel wilt, a new fungal disease vectored by ambrosia beetles is causing mortality among avocado trees in south Florida. The effect of canopy cover on ambrosia beetle abundance was evaluated. Orchards with a dense canopy cover harbored large populations of these beetles. Reducing canopy cover, thus increasing light intensity, suppresses ambrosia beetle abundance, especially for species associated with the pathogen. Canopy management alters the microclimate in avocado orchards, affecting ambrosia beetle abundance and flight activity. Sanitation (e.g., pruning, stumping, and removing LW-affected trees) and replanting with young trees are cultural practices currently used by avocado growers to reduce the incidence of laurel wilt in their orchards.
