Comparison of trapping efficacy for Lasioderma serricorne (F.) adults with electric, pheromone, food attractant and control-adhesive traps

Abstract

During July, August, September and October 1997, in three tobacco stores in the area of Thessaloniki, four types of adhesive traps: electric (black light), pheromone (serricornin and anhydroserricornin), food attractant and control, were used for trapping Lasioderma serricorne (F.) (Coleoptera: Anobiidae). All traps had the same adhesive area based on 29.5×21 cm2 polyethylene sheets. Five replicate comparisons of the four trap types took place. The electric trap caught 8912, the pheromone trap 6608, the food attractant trap 1974 and the control 1231 L. serricorne adults. The electric adhesive trap was significantly more effective than the other traps and the control. The electric trap captured a smaller number of male adults than the pheromone trap but many more females. The ratio between female and male adults was 60.15 : 39.84 for the electric trap, 8.75 : 91.25 for the pheromone trap, 51.57 : 48.42 for the food attractant trap and 43.41 : 56.58 for the control trap.
