Abstract: Kendala dalam budidaya tanaman pisang adalah tingginya serangan hama yang merusak tanaman pada vase vegetatif. Penelitian dilaksanakan di Lahan Kelompok Tani Masyarakat Bersatu Desa Sampali Kecamatan Percut Sei Tuan Kabupaten Deli Serdang pada bulan Mei-Juli 2019. Metode penelitian yang digunakan adalah metode analisis deskriptif menggunakan sampel acak (random sampling). Parameter pengamatan terdiri dari kepadatan populasi, tingkat serangan hama, parasitoid telur, parasitoid larva, parasitoid pupa, identifikasi parasitoid, indeks keragaman jenis, indeks kemerataan jenis, dan kelimpahan relatif. Terdapat 4 jenis parasitoid yaitu Braconidae sp 1 (Hymenoptera: Braconidae), Tachinidae sp 1 (Diptera: Tachinidae), Xanthopimpla gampsura (Hymenoptera: Ichneumonidae) dan Brachymeria lasus Walker (Hymenoptera: Chalcididae). Indeks keragaman parasitoid Erionota thrax L. 0,661369 dalam tingkat keanekaragaman rendah, dan kelimpahan relatif tertinggi Brachymeria lasus Walker 86,87 %, tingkat serangan Erionota thrax pada pisang Barangan mencapai 46 %, tingkat serangan Erionota thrax pada pisang Kepok mencapai 32 %. The constraints in the cultivation of banana plants is the high number of pests that damage plants in vegetative vases. The study was conducted in the Farmers' Land Group of the United Society of Sampali Village, Percut Sei Tuan District, Deli Serdang Regency in May-July 2019. The research method used was descriptive analysis method using (random sampling). Observation parameters consisted of population density, pest attack rate, egg parasitoids, larva parasitoids, pupa parasitoids, parasitoids identification, species diversity index, species evenness index, and relative abundance. There are 4 types of parasitoids namely Braconidae sp 1 (Hymenoptera: Braconidae), Tachinidae sp 1 (Diptera: Tachinidae), Xanthopimpla gampsura (Hymenoptera: Ichneumonidae) and Brachymeria lasus Walker (Hymenoptera: Chalcididae). Erionota thrax L. parasitoids diversity index was 0.661369 in the low diversity level, and the highest relative abundance of Brachymeria lasus Walker was 86.87%, the attack rate of Erionota thrax on Barangan bananas reached 46%, the level of Erionota thrax on Kepok banana reached 32%.
