Matile-Ferrero -- Pseudococcidae. Indigenous coccinellids were often abundant in the first year of the CM infestation, but their populations collapsed later, while the frequency of fields with E. lopezi increased. Overall, satisfactory control was achieved by E. lopezi in all but a few fields concen-trated on extremely poor soils characterized by sand dune vegetation. Bellotti, A.
