Frankliniella schultzei (Trybom 1910) - (yellow flower thrips)

The thrips is widespread in tropical and subtropical regions on buds and flowers of various crops like vegetables and fruit trees. It feeds on the developing shoots, buds and fruits causing dark spots on the leaves and fruit surface, as well as premature drop of flowers and fruits. In addition, it is a vector of several plant viruses, e.g. Tomato spotted wilt virus or Groundnut ringspot virus. Economic damage has been, for example, reported from tomatoes and Capsicum peppers, mainly due to the transmission of viruses.

Vernacular names
• English: yellow flower thrips
tomato thrips
common blossom thrips
• Español: trips común de las flores
• Português: tripes-do-tomate

On the other hand the thrips also feeds on eggs of spider mites and it can delay the development of mite outbreaks. Mite eggs in the diet seem to increase the reproduction of the thrips.

Diagnostic features:

For control, insecticides are predominantly used. However, temporary flooding to kill the soil inhabiting pupae has been also recommended.
