ترکیب گونه های زنبورهای پارازیتویید تخم سن گندم بستگی به بوم و منطقه مورد مطالعه دارد، اما اغلب در یک محدوده ی زمانی و مکانی مشخص، یک یا تعداد کمی از گونه ها، فراوان تر هستند. به منظور بررسی و مقایسه پارامترهای جدول زیستی زنبورهای پارازیتوئید تخم سن گندم، تخم های پارازیته آفت در طول دوره ی تخم ریزی سن گندم از مزارع غلات استان قزوین جمع آوری شده و به آزمایشگاه بخش تحقیقات سن گندم منتقل گردید. در...
بازدارندگی تخمریزی اسانس چهار گونه اکالیپتوس شامل eucalyptus sargentii maiden، e. camaldulensis dehn، e. grandis hill et. maiden وe. viminalis labill روی این آفت بررسی شد. این آزمایش در قالب طرح کاملاً تصادفی در پنج تکرار انجام شد. اسانسهای گیاهی با روش تقطیر با آب تهیه شدند. آزمایش در شرایط دمایی 2±30 درجه ی سلسیوس و رطوبت نسبی 5±60 درصد و در تاریکی انجام شد. نتایج نشان داد که هر چهار اسانس...
A new species of caligid copepod (Siphonostomatoida), Anuretes grandis sp. n., parasitic on the painted sweetlips [Diagramma pictum (Thunberg)] in Taiwan is described. The new species is distinguished from its congeners by having: (1) free margin of cephalothorax not covering fourth pediger, (2) large genital complex longer than 2/3 of the cephalic shield, (3) no maxillary whip, (4) leg 3 with ...
BACKGROUND Burkina Faso implemented the seasonal malaria chemoprevention (SMC) in 2014 in seven pilot health districts, following the new recommendation by the WHO in 2012 for the prevention of the disease in children under five years old, for areas of highly seasonal malaria transmission.The objective of this study was to assess the implementation fidelity of the seasonal malaria chemopreventi...
This paper attempts to provide an additional insight into properties of exceedances and placement statistics described in Bairamov and Eryılmaz (2000). The importance of these concepts in construction of non-parametric tests of equality (identity) of distributions has been demonstrated by Katzenbeisser (1985), (1986), Matveychuk and Petunin (1990), Johnson and Kotz (1991), (1994), Wesolowsky an...

Remote sensing is viewed as a cost-effective alternative to intensive field surveys in assessing site factors that affect growth of Eucalyptus grandis over broad areas. The objective of this study was to assess the utility of hyperspectral remote sensing to discriminate between site qualities in E. grandis plantation in KwaZulu-Natal, South Africa. The relationships between physiology-based hyp...
BACKGROUND Stipa grandis (Poaceae) is one of the dominant species in a typical steppe of the Inner Mongolian Plateau. However, primarily due to heavy grazing, the grasslands have become seriously degraded, and S. grandis has developed a special growth-inhibition phenotype against the stressful habitat. Because of the lack of transcriptomic and genomic information, the understanding of the molec...
Bu çalışma, 2015-2016 yıllarında Iğdır, Ağrı ve Van illeri (Türkiye) hububat alanlarında Süne Eurygaster spp. (Hemiptera: Scutelleridae)’nin yumurta parazitoiti Trissolcus Ashmead, 1893 (Hymenoptera: Scelionidae) türlerini belirlemek amacıyla yürütülmüştür. paketleri zararlının yoğun olarak görüldüğü ekiliş toplanmıştır.
