ABSTRACT
Several aphid species attack the pepper crop cultivated both in open fields and in greenhouses as well. The aphids damage the plants directly by sucking plant sap from the plants and indirectly as a vector of different plant viruses. The aim of this paper was to identify the most abundant aphid species causing damages to pepper cultivated in greenhouse and the evaluation of the efficacy of different insecticides to control these aphids. The experiment was set up in greenhouse located in village Godanci, municipality of Shtimje, while the experiment design was according to randomized Fisher blocks in three replications. Insecticides were from three groups of chemicals: Actara 25 WG (Thiametoksan), Dimetogal (Dimetoat) and Deltarin 2,5 (Deltametrin) and control as well. The insecticides were used in minimal and maximal doses recommended by the producer, shown in the chemical labels. From the total number of aphids recorded the following percentage belongs to the different aphids: Aphis nasturtii (71%), Myzus persicae (14%), Macrosiphum euphorbiae (4%), Aphis gossypii (3%) and other non identified aphids (8%). As for the insecticide efficacy the highest value was recorded with Deltarin used in maximal doses (92.88%), while the lowest one with insecticide Dimetogal used in maximal doses (11.48%). According to the ANOVA there were shown to exist statistical significant differences with regard to the number of aphids species compared to control and different insecticide efficacy to control aphids in pepper crop cultivated in greenhouse.
