Monitoring of stored tobacco insect pests by means of pheromones: the case ofEphestia elutella (Hübner) andLasioderma serricorne Fabricius in South Europe

Results obtained in the monitoring of stored tobacco pests by pheromones are reported.
In GreeceEphestia elutella (Hübner) is likely to have at least 3 generations per year: the first one appears in early May, the second one during the last week of June and the third one— the most populated and the longer lasting—in August. In the same environmentsPlodia interpunctella (Hübner) has shown about 5 generations per year. The first on appeared in late May; the remaining 4—definitely overlapping—are placed in mid-June, in July, in early August and early September.
In Italy four commercial pheromone dispensers effective in trappingLasioderma serricorne Fabricius have been compared. The results pointed out highly significant differences of the efficacy of the four different dispensers tested.L. serricorne was present in the tobacco store from June to October with a quite remarkable increase between August and early September.
