Abstract

In this study, the population levels of Frankliniella occidentalis (Pergande) (Thysanoptera: Thripidae) on Yalova Carliston 341 pepper variety applied at different spore concentrations [104 (recommended dose), 102 (lower-dose) ve 106 (higher-dose)] of Endo Roots Soluble (ERS) (Bioglobal Ltd.) that consist of Glomus intraradices, G. aggregatum, G. clarum, G. monosporus, G. deserticola, G. brasilianum, G. etunicatum, G. mosseage and Gigaspora margarita were determined. Investigation was carried out between the years of 2013 and 2014 in a field of 2.5 acre in Antalya, Aksu-Karaoz. The experimental design was a randomized complete block and all trials were conducted in three replications. The counts of F. occidentalis was performed by 15 pepper flowers which were randomly sampled weekly in each plots. As a result of the study, mean numbers of male, female, nymph and also total individual numbers of F. occidentalis obtained in three different spore concentration of ERS did not differ (P > 0.05) from each other. But the mean number of nymphs and total individual numbers were found significantly differrent (P < 0.05) in control from ERS treatment. The high nymph and total individual numbers were determined in control trials for both years of the study.
