Abstract

A simple method of extracting the eggs ofSitona spp. from the soil is described. From 1973 to 1975 it was used in Spain, France, Italy and Greece to collect in good condition the eggs ofSitona humeralisStephens, a weevil which has recently become a major pest in Australia. A mymarid parasitoid provisionally identified asPatasson lameereiDebauche emerged from these eggs apparently unaffected by the extraction method.

Résumé

Une méthode simple est décrite ici, qui permet d'extraire du sol dans de bonnes conditions de viabilité les œufs deSitona spp. De 1973 à 1975, cette technique a été utilisée en Espagne, France, Italie et Grèce pour récolter des œufs deSitona humeralisStephens, un curculionide récemment devenu un ravageur important surMedicago spp. dans tout le sud de l'Australie. Un mymaride appartenant probablement à l'espècePatasson lameereiDebauche a été trouvé en nombre intéressant sur les œufs deS. humeralis dans les quatre pays cités; son développement ne semble pas affecté non plus par la méthode d'extraction.
