Ecology and behavior of Pezothrips kellyanus (Thysanoptera: Thripidae) on citrus.
The most common thrips species found in Cyprus citrus orchards between 2003 and 2008 were Pezothrips kellyanus (Bagnall) (Thysanoptera: Thripidae), Frankliniella occidentalis (Pergande) (Thysanoptera: Thripidae), and Thrips tabaci (Lindeman) (Thysanoptera: Thripidae). Only Pezothrips kellyanus, Kelly's citrus thrips (KCT) causes feeding damage on citrus fruits in Cyprus. KCT adults prefer to concentrate mostly in the northern and eastern sides of both lemon and grapefruit canopies. The attractiveness of white, sky blue, marine blue, and yellow color to KCT was evaluated. White was found to be the most attractive color to adults of KCT, F. occidentalis, and T. tabaci. A range of incidental and breeding host plants grown within and outside citrus orchards in Cyprus were identified. KCT adults were found on flowers of all citrus varieties, and various other flowering plants including Malva nicaeensis, Malva silvestris, Sinapis alba, Oxalis pes-caprae, Calendula arvensis, Urospermum picroides, Jasminum officinale, Gardenia jasminoides, Jasminum sambac, Prunus dulcis, Mangifera indica, Persea americana, and Eriobotrya japonica. KCT larvae were found only on lemon, grapefruit, Jasmine spp., and Gardenia flowers.
