Insecticidal Potential of Silver Nanoparticles Produced Using Hazelnut Green Leafy Cover Extracts against Hazelnut Aphid, Myzocallis coryli (Goeze, 1778)
Year: 2025
Type: article
Abstract: This study was designed to obtain silver nanoparticles (AgNPs) from green leafy cover organic wastes of Çakıldak and Yomra hazelnut cultivars by green synthesis steps and to determine the insecticidal potential of the obtained products. Characterisation tests (UV-Vis, FTIR, XRD, SEM, STEM, EDS) of the synthesised AgNPs were carried out and the data obtained supported the formation of silver nanoparticles. In order to determine the insecticidal potential of the synthesised AgNPs, four different doses of Ag-nanoparticles (50, 75, 100 and 125 ppm) were sprayed on fourth stage nymph and adult individuals of Hazelnut aphid (M. coryli) at two different temperatures (24-28°C). According to the insecticidal data obtained, it was determined that the type of extract, ambient temperature, dose amount and exposure time were very important in nano-insecticidal studies. The highest insecticidal efficacy was recorded on the fourth day at 28°C, with the 125 ppm dose of AgNPs derived from the Çakıldak cultivar, achieving 100% mortality in both nymphs and adults. The data obtained from the whole study will be a source for similar studies to be carried out in this field in terms of showing the point reached by nanotechnology in this field.
