Abstract

Abstract: The cigarette beetle, Lasioderma serricorne (F.) (Coleoptera: Anobiidae), is an important stored product pest increasingly impacting museums and herbaria. Monitoring methods make use of pheromone traps which can be implemented using chili fruit powder as food attractant. Further laboratory studies evidenced that the main cues involved in this attraction are the terpenoids α -ionone and β -ionone. In this study a trap bioassay was carried out in a bread plant with pheromone traps added with α -ionone or β -ionone at different doses to evaluate the possible enhance of captures determined by such odorants in comparison with traps loaded with the synthetic pheromone alone. Furthermore, in order to optimize the type of device used, the chemical that elicited the highest performance was tested using two types of dispenser: a polyethylene and a silicone one. The results indicated that pheromone traps with the addition of β -ionone at the dose of 10 mg captured the highest amount of L. serricorne adults and significantly more than traps loaded with pheromone alone or with pheromone plus α -ionone. Differently, captures of pheromone traps supplemented with α -ionone didn't differ statistically from those baited solely with the synthetic pheromone. Moreover, the traps baited with β -ionone loaded in polyethylene dispenser allowed a higher number of catches of the adults of the beetle in comparison with those obtained using silicone dispenser. Data indicate that this co-attractant can be exploited to increase sensitivity for monitoring, and/or for mass trapping L. serricorne adults. Highlights: The cigarette beetle, Lasioderma serricorne F. (Coleoptera: Anobiidae), is an important stored product pest commonly monitored by pheromone traps. Objective of this work was to enhance pheromone traps performance using two chemical volatiles that have already demonstrated to attract L. serricorne in laboratory: α-ionone and β-ionone. β-ionone at the dose of 10 mg determined the highest level of adults captured. Polyethylene dispenser determined the best performance in terms of captures. The implementation of pheromone traps with such attractant as a more sensitive device tool is achievable.
