دراسة العوامل المؤثرة على الإصابة بحشرة عثة الزيتون (1788 ,Prays oleae (Bernard في ثلاثة مواقع لزراعة الزيتون في الساحل السوري

Abstract EN

This study aimed to investigate the effect of the most important factors affecting the infestation rate with the olive moth, Prays oleo (Lepidoptera: Yponomeutidae), in three olive growing locations in Attakai and Tartu’s Governorates (Al-Sawda, AinShiqaq and Al Barcia).

The study was carried out during the period 2019-2020.

Results obtained showed that the location had an effect on the infestation rate, and the highest average infestation rate was 33.53% in Al-Barqiah location, followed by 20.86% in Ain Shkak, and the lowest was 16.65% in Al-Sawda location.

Results obtained also showed that the insect generation had an effect on the olive moth infestation rate; infestation of the phyllophagous generation was the highest, followed by the antophagous generation and the carpophagous generation in the three locations.

The x² (Chi-square) test showed that there were significant differences between the infestation rate and the total number of biological enemies, the number of predators and the parasitism rate in the three locations.
