Thrips (Thysanoptera) species associated with wheat and barley in Golestan province, Iran
Authors
Abstract:
به منظور شناسایی گونه‌های تریپس مزارع گندم و جو و تعیین فراوانی و پراکنش آنها، از مزارع گندم و جوی زمستانه‌ی استان گلستان در طول سال‌های 1375 و 1376 نمونه برداری به عمل آمد. در مجموع 32 گونه از 3 خانواده و 16 جنس شناسایی گردید. در این میان تریپس گندم، Haplothrips tritici (Kurdjumov)، با فراوانی 2/70% و 7/55%، به ترتیب روی گندم و جو، در بین تریپس‌های شناخته شده دارای بیشترین فراوانی بود و به عنوان گونه‌ی غالب تعیین شد. پس از آن گونه‌ی Sitothrips arabicus Priesner با فراوانی 5/13% و 1/20% با همان ترتیب، بعد از تریپس گندم دارای بیشترین فراوانی بود. آنالیز رگرسیونی وجود یک رابطه‌ای غیر‌خطی (y = 42.65 + 0.33x – 0.0002x2) بین جمعیت تریپس گندم (y) و ارتفاع (x) را ثابت نمود. اطلاعات مربوط به محل و تاریخ جمع‌آوری، میزبان و پراکنش برای هر گونه ذکر شده است.

Zearalenone contamination of 175 wheat samples produced in 2004 in Golestan province, northern Iran was determined. The 10-20 kg samples collected at different stages, including pre-harvest, before and after storage for 2 months in local silos. Samples were ground and sub-sampled with an analytical Romer mill. Each sample extract was cleaned-up using an immunoaffinity column. Zearalenone levels...

Stemphylium as a monophyletic genus of filamentous ascomycetes, comprises both of saprophytic and plant pathogenic species with worldwide distribution. In an investigation of fungi associated with the black (sooty) head mold of wheat and barley in different regions of Golestan, Alborz and Qazvin provinces, thirty–two isolates with typical characteristics of the genus Stemphylium were recovered....
full textGrass-flower thrips of the genus Chirothrips (Thysanoptera: Thripidae), with a key to species from Iran
Species of the genus Chirothrips Haliday breed and pupate only within grass florets. Each larva is restricted to a single floret, and adult body size is thus presumably related to floret size. Despite this, some Chirothrips species are distinguished only on states that are related to body size. The validity of some commonly recorded members of the C. manicatus species-group, including C. africa...

The wheat thrips, Haplothrips tritici, is known from across eastern Europe and adjoining areas of Asia into western Europe and north Africa, and is widely regarded as a pest of cultivated cereal crops, particularly of Triticum but also of Hordeum (Özsisli 2011). The identity of this thrips species is not in doubt, but a closely similar species, Haplothrips cerealis, was described from Egypt (Pr...

In Iran, as a result of recent changes in nomenclature 201 species and one species group of the insect Order Thysanoptera, are here listed in 70 genera and five families. In considering species listed previously from this country, the presence of 7 species is considered not confirmed, and 12 species are excluded from the Iranian list. Problems in the study of Iranian Thysanoptera are discussed ...
