Species and cultivar preferences of Sitobion avenae and Rhopalosiphum padi to spring barley
Vasilina Maneva, Dina Atanasova
Резюме: The experiment was conducted in the plant protection laboratory of the Institute of Agriculture - Karnobat. Three varieties of two-row and one multi-row spring barley were studied. The degree of attack in the four cultivars, the numerical dynamics of aphids and the relationship of attack with photosynthetic pigments, crude protein and nitrogen content were monitored. Sitobion avenae was observed in the highest density in cultivar Denis, with a maximum of 20 aphids/plant. Rhopalosiphum padi was recorded with a maximum of 88 and 76 aphids/plant, respectively, in Yasmina and Denis varieties. The two-row variety Denis can be defined as the most preferred of both types of aphids, which is probably due to its higher content of total nitrogen in the leaves, which are more nutritious for aphids.
