Abstract

We investigated the thrips fauna on wheat and we discovered 15 species. The most numerous was wheat thrips Haplothrips tritici Kurdjumov. In the same time we investigated the thrips fauna on the plants of the spontaneous flora in the bordering belt surrounding wheat. We collected thrips on 23 plants of the spontaneous flora. A total of 649 thrips specimens have been collected and 32 thrips spieces were identified. The most numerous species was the Onion thrips Thrips tabaci Lindeman. For this species low presence was recorded on wheat and grasses, but high presence on the spontaneous plants. The second most numerous species was Aeolothrips intermedius Bagnall. We found the specimens of this species in great number on wheat as well as on the spontaneous plants surrounding it. 14 species were common for wheat and the spontaneous plants. Sorensen's index of faunistic similarity was 0.6.
