The article presents the main results of phenological observations of the South American tomato moth (Tuta absoluta Meyr.) in tomato crops prediction of the phenophases of tomato moth development is important for planning the system of crop protection against pests, in particular phytophages. The research is based on the collection and analysis of various data, including climatic parameters such as SET and HTC, biological characteristics of the South American tomato moth and population dynamics of the phytophage. The collected data is used to develop a phenological calendar and forecasting models. The resulting model allows predicting periods of mass development of the South American tomato moth in tomato crops based on existing weather and climatic indicators. The expediency of this study is caused by the fragmentation of scientific literature on the study of biological and ecological indicators of the South American tomato moth in Ukraine and the improvement of methods and techniques for monitoring and controlling the number of phytophages, which would increase the productivity and quality of tomato fruits, as well as the localisation and eradication of this pest, in accordance with phytosanitary requirements
