Abstract

Olives are a potential emerging crop for the state of Florida, USA, and the pest arthropods in commercial groves in the state are under-studied. Thrips (order Thysanoptera) are an almost ubiquitous concern among specialty crop growers in Florida. Yellow and blue sticky card traps were used to survey the canopies of trees in 4 North Central Florida olive groves to determine thrips abundance and distribution over 2 growing seasons. Of the 16 species of thrips identified, most were Frankliniella spp., with Florida flower thrips, Frankliniella bispinosa (Morgan) (Thysanoptera: Thripidae), being the most abundant species for both yr. Yellow traps were more effective for most species of thrips, although several species were more abundant on blue traps. No consistent differences between yr existed. Although overall abundance of flower feeding thrips species coincided with flowering events in the olive orchards, there was insufficient flowering to make statistical correlations between the peak of thrips abundance and flowering events in the olive groves. The results of this study will be useful in informing future economic threshold analyses of Thysanoptera in Florida olive groves.
