Apanteles ultor [Hym.: Braconidae] is the dominant and most widely distributed parasite ofEctomyelois ceratoniae (Zeller). The parasitization percent was increased from 10 % during April to 35 % at the end of the pomegranate fruiting season at October. Female parasite preferred to infest the host larvae at the age of, 2–3 days than 7 day old. The average number of host larvae parasitized by single female parasite was 58 under the rearing conditions of 27±2 °C., 55±10% RH and photoperiod of 16 h light per day.

Parasites other thanA. spgroup ultor were:Bracon hebetor Say.,Ascogaster sp., andPhanerotoma sp. [Braconidae];Nemeritis canescens Grav. [Ichneumonidae];Brachymeria sp., andB. aegyptiaca Masi [Chalcididae]; and the secondary parasitePerilampus tristis Mayr [Perilampidae].


Ectomyelois ceratoniae parasites Apanteles ultor pomegranate fruits 


Apanteles sp.groupe ultor [Hym.: Braconidae] est le parasite dominant et le plus largement représenté d'Ectomyelois ceratoniae (Zeller). Le pourcentage de parasitisme augmentait depuis le chiffre de 10 % constaté en avril jusqu'à celui de 35 % observé en octobre à la fin de la saison de fructification des grenadiers. La ♀ du parasite préfère attaquer la jeune larve de l'hôte, âgée de 2 à 3 jours, plutôt que celle plus âgée (7 jours). Le nombre moyen de larves hôtes parasitées par une simple ♀ était de 58 dans les conditions d'élevage de 27±2 °C, 55±10 % d'humidité relative et de 16 h de lumière quotidienne.

Les parasites autres qu'A. sp.groupe ultor furent:Bracon hebetor Say,Ascogaster sp. etPhanerotoma sp. [Braconidae];Nemeritis canescens Grav. [Ichneumonidae];Brachymeria sp., etB. aegyptiaca Masi [Chalcididae] et le parasite secondairePerilampus tristis Mayr [Perilampidae].
