    Abstract: In the natural ecosystems, parasitic Hymenoptera composes the most significant group of biocontrol agents. DNA barcode (658 bp sequence from the 5′-end of cytochromeoxidase I) analysis of hymenopterans collected in a Malaise trap in Chittagong university campus was performed to analyze the diversity of parasitic wasps. In the present study a total ... Show More

    Abstract: Wheat is one of Ethiopia’s foremost important cereal crops in terms of area coverage and volume produced. However, the production and productivity of wheat is constrained by various biotic and a biotic stresses, among which wheat yellow rust disease caused by Puccinia striiformis f.sp. tritici is the one. Field experiments were conducted to develop... Show More

    Abstract: Potato (Solanum tuberosum L.) is the fourth major crop of the world after rice, wheat and maize. Potato is an important crop which holds promise for food to millions of people especially in developing countries. In Ethiopia, the yield per unit area of potato is very low compared to those of other countries. There are many factors that reduce the yi... Show More
