Abstract:
The objective of this study is to determine the main factors that favour the outbreak of date borer (Ectomyelois
ceratoniae) in palm groves in the Ouargla region.
To do so, we opted for an investigator approach whose tool is a survey guide containing a set of questions
around the objective intended for farmers from two different agro-ecosystems. The first consists of 3 palm groves
representing the old oasis system, the palm grove of Béni Brahim, the palm grove of Béni Sissine and the palm grove
of Béni Ouaguine; the second is represented by a new development exploitation located in the area of Hassi Ben
Abdellah.
We started by determining the infestation rates for different date cultivars in different environments, such as
storage sites. We found that the rates are very high in old palm groves with different values for different cultivars
compared to the new plantation, where the rates remain much lower. We then proceeded to determine the
parameters and factors that favour the fluctuation of these rates and explain its high values in the old palm groves of
the Ouargla region.
Finally, we gave some recommendations to limit the damage caused by this pest.
