Study of herbaceous vegetation cover and its effect on biological enemies in three olive growing sites in the Syrian coast

Abstract

The study was carried out in three olive cultivation sites in the Syrian coast, Ain Shaq, Al-Barqiah and Al-Souda, during the 2019-2021. The study aimed to study the relationship between the weeds cover spread in each region and its effect on the vital enemies spread in it. In this study, insect pests and cover were identified. The herbaceous plant, and the natural biological enemies spread in each orchard, and the relationship between weeds and the natural biological enemies in each orchard was determined. The results of the chi-square test showed that there was no correlation between the study areas and the pests prevalent in them, while there was a correlation between the weeds cover and the vital enemies in the three study areas, the Black, Al Barqiah and Ain Shiqaq, meaning that the correlation was linear between the number of weeds in each area and the number of weeds in each area. Vital enemy types of predators and intruders in each well thought out logic.
