Frankliniella bispinosa (Morgan 1913) - (Florida flower thrips)
The thrips is found in the south-eastern U.S.A., as well as on the Bermuda and Bahama islands. It is polyphagous, infesting fruits (e.g. citrus, blueberries), vegetables like green pepper and tomatoes, as well as various other crops. Like related species, they mainly feed on flowers and developing fruits. It is also a vector of the Tomato spotted wilt virus.
Females can reproduce parthenogenetically, laying only male eggs or sexually, producing eggs of both sexes. The eggs are inserted into the plant tissue and the emerging larvae pass through 2 larval stages. These are followed by a propupal and a pupal stage which do not feed and live in the soil. Depending on the environmental conditions, there can be up to 10 generations per year.
Diagnostic features for identification are listed and illustrated below according to Riley et al. (2011). For larvae see Skarlinsky & Funderburk (2016).
| Diagnostic features: | |
|---|---|
| • | colour yellow |
| • | antennae with 8 segments |
| • | pronotal anteromarginal setae shorter than anteroangular setae |
| • | postocular seta IV is reduced compared with Frankliniella occidentalis |
| • | "spine like" setae at apex of second antennal segment enlarged |
