Determination of harmful and beneficial species of Arthropoda phylum which is problem in open field pepper cultivation in Adana province

This study was carried out in order to determine the harmful species, parasitoids and predators of Arthropoda phylum in especially capia red pepper plants grown in the open field of Adana in 2017-2018 In addition, Ç.Ü. Faculty of Agriculture Department of Plant Protection Research-Application parcel of 1-decare open field pepper (capia) sowing-planting by making the economic harmful for pepper Myzus persicae Sulzer and Aphis gossypii Glover (Hemiptera: Aphididae) were followed population developments in two different pepper production season. As a result of the study, 40 harmful species from 22 families belonging to 8 groups were determined; among these harmful species in pepper most common and dense species are Frankliniella occidentalis Pergande, Thrips hawaiiensis Morgan, Phenacoccus madeirensis Green, Nezara viridula L., Myzus persicae Sulzer, Aphis gossypii Glover and were identified as Bemisia argentifolii Bellows & Perring. Among the 27 useful species from 24 families belonging to 8 groups identified, the most common and dense species are; Coccinella septempunctata, L. and Hippodamia (Adonia) variegata Goeze and these were detected in all pepper cultivation area. The population densities of Myzus persicae and Aphis gossypii, which are economically harmful in peppers, were recorded as A. gossypii from the beginning of the season to the end of the season. M. persicae was observed to have very low density in open area pepper cultivation. The population density of aphids in the pepper field in Balcalı was determined to be high enough to require struggle in spring. However, when compared with seasonal climate data, it is revealed that precipitation and high temperatures are very important in decreasing the population density of pests. Thus, when the temperature is in the range of 20-25⁰C with the increase of the relative humidity and precipitation amount, an increase in the aphid population has been found.
