Kermes scales (Allokermes spp.), which resemble galls or buds, typically infest oak trees (Quercus spp.). Their feeding causes branch dieback, flagging, reduced growth rates, and occasionally tree death. We sought to determine their life history and management in Florida, which was thought to differ from northern states. Shoot samples were collected biweekly, and the number and life stages of scales, and presence of natural enemies were recorded. We also conducted an insecticide trial in May 2003, corresponding to the presence of first and second instar A. kingii. Shoot samples were collected biweekly, and nymphal survival was determined.
