The collections of biological material and observations were made during April to July 2015 in rye crops from five localities (Rădăuţi, Horodnic de Jos, , Po- ieni-, country, and Mihăileni, Botoşani country). The biological material were been emphasized with entomological net, with 100 mowings for corn plants at each sampling. In total, we made six samplings were made for each place. From these five localities were been collected and investigated 2821 individuals of thrips and there were identified following species: Aeolothrips intermedius Bagnall (Fam. Aeolothripidae), Limothrips denticornis Haliday, Chirothrips manicatus Haliday, Frankliniella pallida Uzel (Fam. Thripidae) and Haplothrips aculeatus Fabricius (Fam. Phloeothripidae). The most individuals were collected from rye culture from Mihăileni (841 indi- viduals) and the fewest individuals were collected from Marginea ( 247 individuals) (Tab. 1). The Aeolothrips intermedius species is predatory (its individuals are feeding on aphids, thrips etc) and all other species are phytophagous. As dominant species, in all investigated areas, is Haplothrips aculeatus species which registered 80.98% thrips individuals in rye crops from Mihăileni and 56.63% thrips individuals in rye crops from Rădăuţi, followed by Limothrips denticornis and A. intermedius (Tab. 1).

In Romania, systematic studies concerning to the harmful and auxiliary entomo- fauna from rye cultures were not done. However, Bărbulescu (2001), Popov (2003) and Popov and colab. (2009) mentioned 9 species in the Southern of Romania. Table 2. Thrips Diversity from rye cultures in Romania Nothern Nr Species Southern RO (1) Southern RO(2) Moldavia (3) 1.

The dominant species for this region is Haplothrips aculeatus.
