Abstract :In this study, the effect of methanol extracts of three different genotypes insert ignore into journalissuearticles values(Narlısaray, Kavacık, Maltepe); of Cannabis sativa L. on Diuraphis noxia Kurdjumov, Myzus persicae insert ignore into journalissuearticles values(Sulzer); and Aphis fabae insert ignore into journalissuearticles values(Scopoli); insert ignore into journalissuearticles values(Hemiptera: Aphididae); were investigated. In the first stage of the study, 10% concentrations of each cannabis extract were applied on the 2nd and 3rd nymphal stages of aphid species by spraying method. After the end of 24 - 48 and 72 hours of the applications, the alive and dead individuals were recorded and mortality rates were determined. In the second stage, the genotype with the highest effect was used in dose-death trials and LD50 and LD90 values at different doses insert ignore into journalissuearticles values(2.5%, 5%, 7.5% and 10%); were specified. In the census after 72 hours, Narlısaray genotype showed the highest mortality rate with 54.04% on D. noxia. While the effect of Kavacık genotype on M. persicae was found as 23.13%, the highest toxicity record of the same genotype was determined on A. fabae insert ignore into journalissuearticles values(as 91.76%);. According to the dose measurement studies of Kavacık genotype on A. fabae, LD50 and LD90 values were calculated to be 0.33 and 0.110 insert ignore into journalissuearticles values(mg/individual);, respectively. At the results of study, it has been observed that extracts of different genotypes of the industrial cannabis plant are found effective on aphid species and it is thought that they can be used in controlling of these pests.
