Abstract

In an ecological investigation of the gall-forming aphid,Smynthurodes betae Westw., we discovered that more than 20% of the fundatrix galls were parasitized byMonoctonia pistaciaecola Stary (Aphidiidae). This is a new host record for this parasitoid. A Pteromalid hyper-parasite was identified asPachyneuron? leucopiscida Mani. Ecological information on the parasitoid is provided, and the low frequency of parasitoids known from gall-forming aphids, compared with freeliving ones, is discussed.

Résumé

Lors d'une étude écologique du puceron gallicoleSmynthurodes betae Westw., on a découvert que plus de 20% des galles dues aux fondatrices étaient parasitées parMonoctonia pistaciaecola Starý (Aphidiidae). C'est la mention d'un nouvel hôte pour ce parasitoïde. Un hyper-parasitePteromalidae a été identifié commePachyneuron leucopiscida Mani. Une information écologique sur le parasitoïde est fournie et la faible fréquence de parasitoïdes connus d'aphides gallicoles vis-à-vis de celle des pucerons libres est discutée.
