ABSTRACT
Tests were carried out in 28 orange groves, each of 0.4 ha. The control was programmed on the basis of male Planococcus citri (Risso) captures by means of pheromone traps. A single chemical treatment effectuated during the first ten days of September, coinciding with the second male peak capture was sufficient, in the majority of cases, to keep the infestations within a harmless level. In January, at the beginning of the harvest, treated fruit resulted almost entirely free of sooty mold and directly marketable, while 37% of those untreated, were covered by sooty mold and considerably depreciated.
