The objective of the study was to identify parasitoids and amounts of parasitism of the sugarcane aphid, Melanaphis sacchari (Zehntner), in 15 commercial fields of sorghum (Sorghum bicolor (L.) Moench) at Valle del Évora, near Guamúchil, Sinaloa, during the spring growing season of 2020. Three braconid parasitoids emerged from M. sacchari: Lysiphlebus testaceipes (Cresson), L. fabarum (Marshall), and L. fritzmulleri, with the latter two species being first reports for Mexico. Significantly less parasitism (52%) was observed in fields treated with sulfoxaflor, as compared to parasitism (93%) in nontreated fields.
