Field survey showed that the fungus Beauveria bassiana Vuillemin was the predominant natural enemy of Sitona discoideus Gyllenhal larvae and pupae in the Mediterranean region. The present area of distribution of the disease does not, however, include the parts of North Africa, Cyprus, Syria and Iraq with a Mediterranean climate. At localities regularly investigated in southern France over the period 1973\–79, the population dynamics of larval Sitona on volunteer Medicato species appeared to be correlated to some extent with the impact of the fungal disese, which could produce up to 100\% mortality on its host larval populations.

Several isolates of the pathogen were tested in laboratory bioassays to determine their potential activity. One accession from southern France proved particularly virulent to S. discoideus larvae and pupae at the relatively low concentration of 105 conidia/g of soil. This accession seemed worth considering for further quarantine testing and introduction into Australia. Differences between isolates were however confounded by varying ages of the cultures involved.

A simple method of extracting the eggs of Sitona 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 of Sitona humeralis STEPHENS, a weevil which has recently become a major pest in Australia. A mymarid parasitoid provisionally identified as Patasson lameerei DEBAUCHE emerged from these eggs apparently unaffected by the extraction method.

Following investigations carried out in 15 countries of the Western Palaearctic region, the distribution of 180 species of ichneumonids obtained from plants of Medicago spp. growing in a Mediterranean type climate is recorded.
