Important thrips attacking wheat in central Anatolia.
As a result of studies in central Anatolia, Turkey, on some economically important species of Thysanoptera infesting wheat in all the areas examined, a list is given of the 6 most injurious species, with notes on their distribution within Turkey and in the world and on their alternative food-plants; these were Haplothrips tritici Kurd., Aptinothrips rufus (Hal.), Sitothrips arabicus Priesn., Anaphothrips obscurus (Mull.), Frankliniella tenuicornis (Uzel) and Thrips tabaci Lind. The commonest of these species was H. tritici, which constituted 76-99% of all species of Thysanoptera found on wheat and some other cereals; details are given on the feeding habits of the nymphs and adults and on the resulting damage to the leaf-sheaths, ears and grains of wheat. During the studies 6 further species were found infesting other cereals and grasses; these species, which were rare on wheat, are also named.
