Preparation of forecasting model of Grapevine moth
By researchers of the Iranian Research Institute of Plant Protection

According to the Public Relations office of the Iranian Research Institute of Plant Protection, Dr. Hossein Ranjbar, the faculty member of the Agricultural Entomology Research Department and the lead manager of the project "preparation of forecasting model of Grapevine moth" in collaboration with the other researchers of the project have prepared a forecasting model to manage the grapevine moth (Lobesia botrana Denis & Schiffermüller) Which is one of the most important pests of Iranian vineyards.

Until now, in our country, pheromone traps were used to determine the most appropriate time for spraying pesticides against this pest, while according to the experts the use of pheromone traps in forecasting is not accurate enough and has been criticized a lot. In this regard, seasonal fluctuations of grapevine moth population in vineyards of Qazvin and Kurdistan provinces were studied and based on that, a temperature-based phenology model was prepared for the pest populations in these two provinces, and in order to prepare a forecasting model, the method of Growing Degree Hours (GDH) was used. Since the beginning of 1400, the validation and development of the application of the model has been carried out by the Plant Protection Organization with the cooperation and under the supervision of the project manager.
