    (Faculté Science de la Nature et de la Vie et Sciences de la Terre - Université de Ghardaïa, 2017) Bousba, Zohra; Boucina, Zoubida; Abdelmalek, khédidja
    In this humble work, we have evaluated the main enemies that attack vegetable cultivation on the level of new reclamation in the Al-Meniaa area and what are the means of combating these enemies. These enemies and pests of vegetable crops cause losses each year from various agricultural products and in all agricultural fields. Knowledge of enemies and pests affecting vegetable crops is necessary to identify and quantify production losses and thus identify appropriate prevention measures. The area has witnessed significant expansion in agricultural areas, land development and the establishment of new reclamation, with various predictions of palm trees, tree crops and fodder crops as well as vegetable crops that are present in most areas. This work shows that vegetable crops are vulnerable to many pests and enemies at the level of new reclamation, causing significant damage. The main main enemies are The aphids, Whiteflies and tomato leaf miners.

    Enquête des problèmes phytosanitaires dans l’ancienne oasis d’EL Ménéa (W. Ghardaïa)
    (Faculté Science de la Nature et de la Vie et Sciences de la Terre - Université de Ghardaïa, 2019) Abdelmalek, khédidja; Bousba, zohra
    Our job is to study the main phytosanitary problems in the old oasis of El Ménéa. We conducted surveys of a sample of farmers in the study area. We used a survey guide to characterize farms, identify phytosanitary problems, damage and control methods. The results indicate the presence of different types of pests such as citrus leafminer, citrus fruit, aphid, white scale, date moth and mole cricket. Only one cryptogamy disease has been encountered, this is blue and green mold. In contrast, physiological diseases are more numerous and include iron deficiency, leaf rolling and yellowing, and fruit drop. On the other hand, we have noticed the frequent presence of weeds such as Quackgrass and Diss. For the means of control practiced against these phytosanitary problems, the majority of the farmers use rather simple means of struggle. There is no effective struggle by farmers against these enemies.
