چکیده مقاله:
The olive psylla, Euphyllura olivine, is the most important pest of olive trees in Tehran urban green space and causes severe damages on these trees every year. Chemical control is the major method to manage the pest. Because of deleterious effects of the chemical compounds, the use of plant based pesticides would be a safe and proper method for the pest control. In this study, the contact toxicity of a new botanical pesticide, named Tond-eksir, was evaluated on pupa and adults. Bioassay was conducted in a completely randomized design with spraying method. After conducting preliminary tests and determining the range of fecundity of ۲۰-۸۰%, the main test was performed in laboratory conditions in three replicates and five concentrations of Tond-eksir compound. In each replicate, Data analysis was performed using Polo Plus software. The bioassay was designed to determine LC۵۰ values of ۲۴ h post treatments. LC۵۰ was estimated to be ۱.۰۱۸ and ۱.۰۲۴ ppm on pupa and adults, respectively. Findings of this study, indicated the possibility of practical use of Tond-eksir in management of Olive psylla beetle in urban landscape.
