Abstract

The collar borer (Elasmopalpus lignosellus) is a soil-dwelling pest that causes severe damage to several crops, being necessary the use of early detection tools. This study aimed to evaluate the efficacy and selectivity of synthetic sex pheromone blends in monitoring Elasmopalpus lignosellus populations in soybean, as well as to assess their attractiveness to non-target lepidopteran species. The performances of synthetic formulations were compared with those of live virgin females in the field over two growing seasons. The ternary (Z9-14:Ac, Z11-16:Ac, and Z9-16:OAc) and the quaternary (Z9-14:Ac, Z11-16:Ac, Z11-16:OH, and Z9-16:OAc) mixtures demonstrated a strong potential as field monitoring tools.
