CONTROL OF TWO SPOTTED SPIDER MITES TETRANYCHUS URTICAE KOCH, 1836 (ACARI: TETRANYCHIDAE) BY APPLICATION EXTRACTS ON BEAN PLANT

Abstract

Chemical control used in agriculture is the most frequently used control method against agricultural pests today. However, in recent years, this method has serious negative effects on living-environmental health and beneficial microorganisms, as well as many reasons such as the development of resistance of disease, pest and weed factors against agricultural pesticides used in chemical control, forcing researchers to develop different alternatives within an integrated control system. he pushed. Tetranychus urticae Koch. (Acari: Tetranychidae) causes serious economic losses in many vegetables, fruits, industrial and ornamental plants. Resistance to acaricides in T. urticae is still an important problem both in our country and around the world. Due to reasons such as its high reproductive power and rapid development of resistance to pesticides, pesticides are intensively used against this pest. This study aimed to reveal the effectiveness of herbal extracts such as peppermint and lemon instead of pesticides on T. urticae as an alternative control method. This study was carried out in Tatarlı village of Shamkir district in 2022-2023. Various attractant and repellent effects on T. urticae adults were investigated under field conditions by applying two different extracts prepared from peppermint and lemon to the bean plant in different ways, including seed and leaf application. For this purpose, White bean variety was searched. 30% ethanol was used in the preparation of the Peppermint and Citrus lemon extracts. Accordingly, as a result of mite counts (visual control), among all treatments, only lemon extract seed application showed a significant repellent effect on T. urticae, at a rate of 37.12%, compared to the control application. It was determined that lemon extract leaf application attracted 20.3% more mite individuals than the control application, and this application was found to have a more attractant effect on individuals. It was determined that T. urticae was sensitive to herbal essential oils and lemon-containing seed application had a more repellent effect on individuals.
