FENOLOGIJA I MONITORING INSEKATA U ZASADIMA KRUŠKE NA PODRUČJU ISTOČNOG SARAJEVA

Abstract

Phenology and monitoring of pear insects was realized in 2011 and 2022 in intensive orchards, in the locations Vojkovići and Kula, in semi-intensive orchards in the locations Tilava and Petrovići, and in extensive orchards in the location Kasindo. Insects, as well as other organisms, react with a series of periodic phenomena to all climate and phenological changes. The aim of the study was to determine the time of occurrence and activity of overwintering forms of insects, as well as other successive phenological stages in their life cycle, in order to ensure their successful control. During the dormancy of vegetation and the vegetation season, harmful and useful species were determined and their activity were shown by monthly decades. The period of their activity was quite uniform in all locations, regardless of the type of orchard, except in the location Petrovići, which was located at a higher altitude. That was reflected on the later movement of vegetation and the activity of insects in this location.
