Results on application of attracticide method in the combined control of cigarette beetle, Lasioderma serricorne and tobacco moth, Ephestia elutella, infesting a tobacco processing facility are reported. Experimental devices with cross-panel stripes treated with microencapsulated permethrin at 6% (a.i.) and baited at same time with (4,6-dimethyl-7-hydroxynonan-3-one) serricornin and (Z,E)-9,12-tetradecadien-1 ol acetate (TDA) were used for 2 years (2017 and 2018) in an Italian tobacco processing facility. The experiment demonstrated that the presence of both serricornin and TDA dispensers on cross-panel striped devices had no affect on the numbers of L. serricorne and E. elutella male adults caught. After 2 years, the densities of adult males were clearly suppressed in room treated with attracticide compared to control room. Thus, the 2017–2018 experiment suggests that attracticide devices with two pheromone lures and microencapsulated permethrin at 6% (a.i.) can be effective suppression tools for managing combined pest populations of L. serricorne and E. elutella in tobacco facilities. The reduction of male infestation by L. serricorne ranged from 36% to 87%, and in E. elutella, the reduction of infestation ranged from 63% to 91%.

Abstract
Results on application of attracticide method in the combined control of cigarette beetle, Lasioderma serricorne and tobacco moth, Ephestia elutella, infesting a tobacco processing facility are reported. Experimental devices with cross-panel stripes treated with microencapsulated permethrin at 6% (a.i.) and baited at same time with (4,6-dimethyl-7-hydroxynonan-3-one) serricornin and (Z,E)-9,12-tetradecadien-1 ol acetate (TDA) were used for 2 years (2017 and 2018) in an Italian tobacco processing facility. The experiment demonstrated that the presence of both serricornin and TDA dispensers on cross-panel striped devices had no affect on the numbers of L. serricorne and E. elutella male adults caught. After 2 years, the densities of adult males were clearly suppressed in room treated with attracticide compared to control room. Thus, the 2017–2018 experiment suggests that attracticide devices with two pheromone lures and microencapsulated permethrin at 6% (a.i.) can be effective suppression tools for managing combined pest populations of L. serricorne and E. elutella in tobacco facilities. The reduction of male infestation by L. serricorne ranged from 36% to 87%, and in E. elutella, the reduction of infestation ranged from 63% to 91%.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
