Cigarette beetle, Lasioderma serricorne (Coleoptera: Anobiidae), is a cosmopolitan pest of dried plant products including cured tobacco, nuts, herbs, spices, and processed grain products. Developing larvae burrow into foodstuffs and contaminate it with pupal cocoons, frass, and bodies. We investigated the use of mating disruption to mitigate these insect populations before they require fumigation. In each of four tobacco receiving stations, male cigarette beetles were monitored using sex pheromone baited sticky traps while female oviposition was monitored using small cups filled with attractive media. Halfway through the storage year, two receiving stations were provisioned with custom made pheromone dispensers that passively released synthetic sex pheromone to confuse males and prevent them from locating and mating with females. Data show that deployment of pheromone dispensers resulted in an immediate shutdown of captures in the sticky traps and very few progeny in oviposition cups. These results suggest that mating disruption should be further developed as an insecticide free control tactic for mitigating cigarette beetle populations inside tobacco receiving stations.
