Extensive research has recently been conducted\udto shed light on mating behavioural asymmetries in various\udspecies of vertebrates. However, little is available on this\udkey issue for invertebrates, especially for species of the\udorder Coleoptera. In the present study, we highlighted the\udpresence of four population-level lateralized mating traits\udin the mating behaviour of an alien and invasive pest of\udstored products, the khapra beetle, Trogoderma granarium\ud(Dermestidae). Male recognition and mounting, as well as\udthe female post-copulation kicks, were left-biased, while\udmale foreleg tapping acts were right-biased. Notably, leftbiased\udasymmetries in the recognition approach led to\udsignificant differences in recognition duration, the number\udof head wagging acts, whole mating duration and, most\udimportantly, male mating success. Overall, the results\udreported here represent a unique example of four\udsubsequent mating traits lateralized at the population level\udwhich influence male mating success. From an applied\udperspective, the quantification of lateralized mating traits is\udexpected to contribute to a better understanding of key\udbiological traits of this species, which can be used for the\udprediction of its spread and population growth parameters
