Acetylated glyceride（AG）is a unique pesticide composed of food additives that regulate insect behaviors. Our previous findings showed a reduction in male courtship songs and courting pairs on AG-treated host leaves, as well as repellence of adult MEAM1（Middle East Asia Minor 1）of Bemisia tabaci（Gennadius）（Hemiptera: Aleyrodidae）. Here, we investigated the efficacy of AG on the mutual courtship behaviors of MEDQ1（Mediterranean Q1）B. tabaci, Trialeurodes vaporariorum（Westwood）（Hemiptera: Aleyrodidae）, and Liriomyza sativae（Blanchard）（Diptera: Agromyzidae）. We acoustically analyzed the courtship and response songs of test pairs on leaves after exchanging AG-treated leaves with non-treated leaves. Sexual communication and the rate of mating success for MEDQ1 both decreased significantly on treated leaves. A significant reduction in male courtship songs with AG application was also observed in T. vaporariorum. For L. sativae, courtship songs were performed in 88.2% of the test pairs on non-treated leaves, with a mating success rate of 58.8%； in contrast, only 29.6% of the test pairs on the treated leaves produced courtship songs, with a mating success rate of 7.4%. These results suggest that AG negatively influenced the continuity of mutual courtship behavior, which consists of male songs and female response songs.
