Abstract

Thrips palmi Karny, 1925 is a polyphagous, phytophagous thrips species recorded on numerous plant species from more than 36 families, with species from Cucurbitaceae and Solanaceae predominating. It is a vector of destructive plant tospoviruses. It appears to have originated in Southern Asia. In the EU the species has a status as a quarantine harmful organism and it is regularly intercepted in imported non-European shipments of cut-flowers, fruits and vegetables. T. palmi presents a serious phytosanitary risk for agricultural production in the Mediterranean basin. A survey of quarantine species T. palmi started in Croatia in 2021. Visual inspections were conducted in vegetable plantations in greenhouses as well as on ornamentals in nurseries and garden centers, in 34 localities in 13 counties. Adult thrips specimens were collected by beating of plants on a white plastic tray or directly from plant organs with a fine brush and stored in AGA mixture in Eppendorf vials until laboratory analysis. Altogether 46 visual inspections were carried out and 101 samples of trips from 43 plant species were collected for laboratory analysis. Thrips from collected samples were identified to the species level on the basis of morphological characters of adult females, using classical identification method according to the EPPO diagnostic protocol PM 7/3 (3) and relevant morphological keys. Nineteen species of thrips were identified in the collected samples, of which Chaetanaphothrips orchidii (Moulton, 1907) and Scirtothrips cf. canizoi Titchak, 1964 are new for the thrips fauna in Croatia. Quarantine species T. palmi was not determined in any of the analyzed samples.
