There was significant difference between density and size of different species of earthworms. The earthworm species Lampito mauritii is the most common species of Gorakhpur district. The Metaphire posthuma, Eutyphoeus nicholsoni, Eutyphoeus incommodus, Eutyphoeu...

Debris flows are among the most destructive of all water-related disasters. They mainly affect mountain areas in a wide range of morphoclimatic environments. Therefore, accurate prediction of their run out distances, magnitudes and velocities plays a role of paramount importance, in order to plan and design appropriate structural and non-structural defence measures. In this context, a number of...

The work treats 52 species-group names related to genus Agrilus incorrectly cited in the world catalogue of Bellamy (2008).

Arbuscular mycorrhizal (AM) fungi constitute promising biofertilizers for the deployment of a sustainable agriculture. However, evaluation benefits in field is poorly documented, notably fruit tree orchards, and concerns exclusively growth performance nutrition. Here, we evaluated persistence beneficial effects AM fungal inoculation on two jujube (Ziziphus mauritiana Lam.) cultivars (Tasset Gol...

وراثت مقاومت سفیدبالک گلخانه، Trialeurodes vaporariorum Westwood (Hemiptera: Aleyrodidae)، به دو ترکیب ایمیداکلوپرید و کلرپایریفوس مورد مطالعه قرار گرفت. در این پژوهش، از جمعیت فیلستان ورامین (FL) عنوان والد مقاوم فردیس کرج (FR) حساس استفاده شد. مقدار ترتیب حدودا 62/13 91/14 برابر بود. عدم وجود اختلاف معنی‌دار LC50 روی تلاقی‌های F1 (R♂×S♀) Fʹ1 (R♀×S♂) نشان داد که T. نوع اتوزومی (غیرجنسی) است. ه...
