ABUNDANCE OF BENEFICIAL AND HARMFUL INSECTS IN PLUM ORCHARDS IN POBORU COMMUNE ECOSYSTEMS

Abstract

Each ecosystem presents a certain entomofauna that has an important role in maintaining the biological balance during its existence, reducing the need to apply chemical treatments. This paper presents a synthesis of the results of experiments carried out in three years of research in the North-Eastern part of Olt County. The experiments were carried out in a plum orchard in the Poboru locality, located in the North-Eastern part of Olt County, with low hilly terrain and a moderate temperate-continental climate, with an annual average rainfall of 600-700 mm. During the period 2021-2023, Barber traps, yellow sticky traps and pheromone traps were placed. 6 harvests were carried out each year from May to September. The number of individuals identified was variable from one year to another, being influenced by the crop and environmental conditions.
