Pine Sawfly L Arvae, Neodiprion spp., In Florida

Pine sawfly larvae, Neodiprion spp., are the most common defoliating insects of pine trees, Pinus spp., in Florida. Sawfly infestations can cause growth loss and mortality, especially when followed by secondary attacks by bark and wood-boring beetles (Coleoptera: Scolytidae, Cerambycidae, Buprestidae). Trees of all ages are susceptible to sawfly defoliation (Barnard and Dixon 1983; Coppel and Benjamin 1965).
