Determination of citrus pests and infestation rate of the important ones in citrus nurseries and newly established citrus orchards in Aydin province

It was aimed in this study to determine pests and their infestation rates in citrus nurseries and citrus groves newly established. Studies were conducted in three nurseries and in five newly established Satsuma mandarin groves having at least 500 seedling in each in the years of 2014-2015. Observations were made on the seedlings in an adequate numbers periodically every two weeks both in the nurseries and groves. Pests were sampled for their identifications. As results, Helix aspersa (Gastropoda: Helicidae), Tetranychus urticae (Acarina: Tetranychidae), Aphis gossypii (Hemiptera: Aphididae), Dialeurodes citri (Hemiptera: Aleyrodidae), Aonidiella aurantii (Hemiptera: Diaspididae), Planococcus citri (Hemiptera: Pseudococcidaee), Asymmetrasca decedens (Hem.: Cicadellidae), and Phyllocnistis citrella (Lepidoptera: Gracillaridae) were determined on the seedlings in nurseries and groves. Infestation rates of the pests were observed during the vegetation, and significant differences on infestation rates were found in infestation rates in nurseries and groves. It can be concluded that the differences could be appeard as a result of the climatic factors and different cultural applications in nurseries and groves. Keywords: Citrus, Seedling, Pest, Aydın
