Abstract The Asian citrus psyllid (ACP) is a vector of a pathogen associated with greening and Train Sets thus a major problem in citriculture worldwide.Lures are much needed for improving ACP trapping systems for monitoring populations and surveillance.Previously, we have identified acetic acid as a putative sex pheromone and measured formic acid- and propionic acid-elicited robust electroantennographic responses.We have now thoroughly examined in indoor behavioral assays (4-way olfactometer) and field tests the feasibility of these three semiochemicals as potential lures Apparel Fabric by the Yard for trapping ACP.Formic acid, acetic acid, and propionic acid at appropriate doses are male-specific attractants and suitable lures for ACP traps, but they do not act synergistically.

An acetic acid-based homemade lure, prepared by impregnating the attractant in a polymer, was active for a day.A newly developed slow-release formulation had equal performance but lasted longer, thus leading to an important improvement in ACP trap capture at low population densities.
