Abstract
This article contains new information on the phenology of the Archips rosana L. The purpose of the study is to determine the phenological features and identify vulnerable stages of rose leaf roller development. The practical significance lies in the fact that these studies will allow us to find out more detailed understanding of the ecological adaptation of this species to local habitat conditions, which subsequently contributes to the management of populations of this insect pest. The research was conducted on the territory of the Ile-Alatau State National Natural Park. The material was obtained by the authors during two field seasons, 2018-2019. The research methods are classical entomological methods, such as trapping males and females using an entomological net, semi-stationary accounting at monitoring sites, and growing leaf rollers by cultivating larvae in the entomology laboratory of the Institute of Zoology. As a result of the research, the phenological features of the rose leaf roller in these territories were clarified. The influence of temperature and relative humidity (%) on the development of the rose leaf roller, Archips rosana L., in 2018 and 2019 has been studied. During the study, vulnerable stages of development were identified - the stage of larvae of 1-2 ages, which appear in the studied territories from the second decade of April to the first decade of May.
