Abstract

In 2000-2002 thrips species were collected from mature white cabbage head leaves in Hungary. The total number of the sampled specimens was 4226. Out of the 3374 identified adults Thrips tabaci was predominant (91.3%). Frankliniella tenuicornis was found in significant number (6.9%) with rather extraordinary appearance in 2000 (15.1%) but in the other years its frequency was lower (0.5%, 1.9% respectively). The rest of the adults (1.8%) were: Frankliniella intonsa, Aeolothrips intermedius, Thrips angusticeps, Thrips atratus, Haplothrips aculeatus, Limothrips denticornis, Anaphothrips obscurus, Chirothrips manicatus and Scolothrips longicornis. The 852 second instar larvae were also identified. 96.4% was Thrips tabaci, 2.7% Thrips angusticeps and 0.8% Anaphothrips obscurus. In spite of the fact that in 2000 15.1% of the adults on cabbage was Frankliniella tenuicornis, not a single larva was found. Therefore we concluded that in Hungary it is only the thelytokous populations of Thrips tabaci that are of high importance as thrips pest of white cabbage.
