The Algerian forests are essentially constituted of Quercus suber and Quercus faginea; they shelter a much-diversified entomofaune among which the species gall. We were interested in the collection and identification of the various galls which settle down on the different organs of the Quercus suber and of the Quercus faginea. We have chosen four eastern Algerian forests to realize our work, the forest of the National Park of El Kala, the national forest of Ouled Bechih in Souk-Ahras, the forest of Edough in Annaba and the forest of Collo (Skikda). The samplings concern leaves, buds, flowers, twigs and acorns of the trees of Quercus suber and Quercus faginea. We have highlighted12 species of galls. Weincluded those distributed on leaves (Neuroterus minutulus, Neuroterus saltans and Neuroterus quercusbaccarum), buds (Andricus hispanicus, Andricus pseudoinflator, Biorhiza pallida), flowers (Andricus grossulariae, Andricus quercusramuli), twigs (Callirhytis glandium, Synophrus olivieri and Synophrus politus) and acorns (Callirhytis glandium). |
