Mating data-LO

<i>Latheticus oryzae</i> Waterhouse is a cosmopolitan secondary pest of stored products, yet it remains an understudied species. This study examined the courtship and mating sequence of <i>L. oryzae</i>, as well as the behavioral lateralization, exploring its influence on copulation success. Males of <i>L. oryzae</i> showed a left-biased tendency across various phases of mating (i.e., approach of the female, mounting, leaving). Approaching and leaving side significantly affected copulation success rates, in contrast to the mounting side. Left-biased <i>L. oryzae</i> males achieved higher mating success and demonstrated significantly shorter mate detection and copulation attempt durations compared to males of the other directions (back, front, and right). From a control perspective, the strong directional tendency of <i>L. oryzae</i> at the mating behavior may offer novel opportunities for pest management strategies that exploit lateralization-based disruptions. Overall, these findings establish the first comprehensive description of the mating procedure of <i>L. oryzae</i> and highlight the functional significance of behavioral asymmetries in the copulation success of stored-product pests.
