| زنبور ساقه خوار غلاتCephus pygmaeus ، یکی از آفات مهم گندم میباشد. لارو این آفت با تغذیه در داخل ساقه گندم موجب خسارت میگردد. این پروژه با هدف ارزیابی دو رقم رایج گندم (مروارید و گنبد)، چهار لاین امیدبخش گندم (N-91-17, N-91-9, N-91-10, N-91-14) و یک رقم جو (صحرا) نسبت به خسارت زنبور ساقه خوار غلات، در قالب بلوکهای کامل تصادفی با 7 تیمار و 3 تکرار در منطقه فریم شهرستان ساری در طی سالهای زراعی 94-1393 و 95-1394 به اجرا در آمد. پس از رسیدن محصول، تعداد بوتههای موجود در یک مترمربع از هر کرت برداشت، تعداد ساقههای آفت زده شمارش و درصد آلودگی ساقهها محاسبه گردید. بهعلاوه قطر حداکثر 20 ساقه سالم و 20 ساقه آفت زده، وزن صد دانه بوتههای سالم و آفت زده و وزن دانه استحصالی یک مترمربع از هر کرت اندازهگیری شد. دادهها با نرم افزار MSTAT-C آنالیز و میانگین صفات مورد بررسی با استفاده از آزمون توکی مقایسه شدند. نتایج نشان داد که از نظر میزان آلودگی به زنبور ساقه خوار غلات، بین ارقام و لاینهای مختلف گندم اختلاف معنیدار وجود نداشت ولی رقم جو صحرا بهصورت معنیداری نسبت به تیمارهای گندم آلودگی کمتری داشت. | ||

| C Cereal stem sawfly, Cephus pygmaeus (Hym: Cephidae), is an important wheat pest. The pest larvae feed inside wheat stems and cause damage. This project was carried out in a completely randomized block design with 7 treatment and 3 replications (21 plots, 3 m×4 m) in Farim region, Sari, Iran, during 2015-2016. Evaluation of damage caused by the pest on two common wheat cultivars (Morvarid and Gonbad), four promising wheat lines (N91-9, N91-10, N91-14 and N91-17) and one barley cultivar (Sahra) were investigated. On harvesting time, all plants located in 1 m2 of each plot were sampled including their roots. The numbers of infested stems were counted and percentage of infestation measured. Diameter of 20 intact and 20 infested stems, 100 kernel weights of healthy and infested plants and the grain weight of 1 m2 of each plot were measured. Data were analyzed by MSTAT-C software and the means were compared using Tukey test. Regarding the percentage of infestation, there was no significant different between the common cultivars and the promising lines of wheat. However, the barley cultivar (Sahra) had significantly less infestation compare to wheat treatments. | ||
