MetadataShow full item record
Field surveys for aphids infesting potato crops in three most important localities for potato production in Kosovo (Podujevë, Prishtinë and Vushtrri) were conducted in vegetation seasons of 2018–2019. With the purpose to monitor and confirm the aphid composition in potatoes, aphid leaf count was used as a method which is applied worldwide. Sampling for aphids from the leaves of potato plants was undertaken during cropping season, every 10 days, where 100 leaves were taken at random and checked in triplicates, from each field. During of this experimental work, the following aphid species were registered Myzus persicae, Macrosiphum euphorbiae, Aphis nasturtii and Aulacorthum solani. From the total number of aphids recorded (4,210 individuals), the following percentage belongs to the different aphids: M. persicae (57.24%), A. nasturtii (25.72%), A. solani (7.77%), M. euphorbiae (5.68%), and other none identified aphids (3.59%). Relying on the results of this research we have confirmed to exist statistical significant differences with regard to the number of aphid’s species according to the localities and aphids that infests the potatoes. With the goal to manage and control aphids spread infields with potatoes, it is extremely useful to evaluate and to see the possibility for an Integrated Management against these pests at farmer level.
