Abstract The Asian citrus psyllid (ACP) is a vector of a pathogen associated with greening and 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 Animal Toys 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 for trapping ACP.Formic acid, acetic acid, and propionic acid at appropriate doses are male-specific attractants and suitable lures for ACP traps, but Intermediate 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.
