Validation of the method for evaluating the efficacy of food baits against pharaoh ant colonies

The validation of the method for testing the effectiveness of food baits against colonies of the Pharaoh ant using experiments with commercially produced and laboratory-prepared sugar baits containing insecticides from different chemical groups was carried out. We studied baits based on boron compounds (boric acid and sodium tetraborate), neonicotinoids (thiamethoxam, imidacloprid, and acetamiprid), oxadiazines (indoxacarb), phenylpyrazoles (fipronil), carbamates (methomyl), pyrroles (chlorfenapyr) amidinohydrazones (hydramethylnon), avermectins (abamectin), and insect growth regulators (pyriproxyfen). The proposed algorithm for conducting experiments covers the whole variety of active ingredients of insecticides used in baits. The verification of several dozen products intended for the elimination of colonies of the Pharaoh ant has shown that most of the products are suitable for the requirements for efficacy indices.
