Parasites ofMonellia caryella [Hom.: Aphididae]: Phenology and effect on the aphid population in pecan orchards in Israel

Abstract

One primary parasite,Trioxys pallidus (Haliday) (Hym.: Braconidae), and a secondary parasite,Aphidencyrtus sp., were identified from the blackmargined aphid,Monellia caryella (Fitch) (Hom.: Aphididae), in Israeli pecan orchards. The average total parasitism for all locations sampled was 13.5%. Although a hyperparasite was discovered, it had no significantly detrimental effect on the parasite.

Résumé

Un parasite primaire,Trioxys pallidus (Haliday) (Hym.: Braconidae) et un parasite secondaireAphidencyrtus sp. ont été identifiés du puceronMonellia caryella (Fitch) (Hom.: Aphididae) dans les vergers israéliens de pacaniers. La moyenne du parasitisme total de toutes les localités échantillonnées était de 13,5%. Quoiqu'un hyperparasitisme ait été découvert, il n'a pas d'effet néfaste significatif sur le parasite.
