Contributions to the study of Thysanoptera of small-grain cereal crops.
In 1966-68, 24 species of Thysanoptera were collected from fields of wheat, rye, barley and oats in the Simnic region of Romania. The suborder Terebrantia predominated, comprising 71% of the total collection of 5818 insects and including 5.4% of the family Thripidae and 17% of Aelothripidae; of the suborder Tubulifera, the only family present was Phloeothripidae, which formed 29% of the total collection. The abundance of each species collected from each crop is shown in tables. The most abundant species were Haplothrips tritici Kurd. (especially on wheat and oats), H. aculeatus (F.) (especially on rye, barley and oats) and Frankliniella intonsa (Tryb.) (especially on oats).
