The results of the study are the diversity index of natural enemy insects obtained in the three places are balanced at 2.26 (Ulul Mayang Village), 2.14 (Kebun Baru Village), and 2.06 (Batu Ralang Village); with the highest evenness index value with a value of 1.0 in Ulul Mayang Village, followed by Kebun Baru Village with a value of 0.98 and Batu Ralang Village with a value of 0.98 with the meaning of moderate evenness, and the dominance index of the three villages with an index of 0.06 shows that from the three villages there are no dominant insects.
