    Abstract
    The Test of the effectiveness of local isolate nematode Steinernema sp. for control bagworm (Metisa plana) (Lepidoptera: Psychidae) in the Laboratory and in the Field. Under the supervision of Maryani Cyccu Tobing and Lisnawita. The research in the laboratory was aimed to identify nematode entomophatogen Steinernema sp. from Langkat District, Deli Serdang and from Serdang Bedagai and to find the right dosage in control M.plana larvae in the field. The research conducted in the laboratory used factorial RAL (Complete random Design) with two factors and four repetitions. The first factor, juvenile infective (ji), consisted of 0, 90,180, and 270 ji and the second factor, M.plana larvae, consisted of ten instar I, II, and III larvae. The research conducted in the field used factorial RAK (Cluster Random Design) with two factors and four replications. The first factors consisted of 0, 200, 400, and 600 ji and the second factor, M.plana larvae, consisted of instar I, II, and III larvae. The result of the research conducted in the laboratory showed that Steinernema sp. genus was found in the three locations where the samples were taken, and the result of the research conducted in the field showed that highest mortality rate (100%) was three days after the application with the density of Steinernema sp. 600 ji.
     
    Uji efektifitas nematoda Steinernema sp. isolat lokal untuk mengendalikan ulat kantong (Metisa plana) (Lepidoptera: Psychidae) di laboratorium dan lapangan di bawah bimbingan Maryani Cyccu Tobing dan Lisnawita. Penelitian di laboratorium bertujuan untuk mengidentifikasi nematoda entomopatogen Steinernema sp. dari Kabupaten Langkat, Deli Serdang dan Serdang Bedagai dan mencari dosis yang tepat dalam mengendalikan larva M. plana di lapangan. Penelitian di laboratorium menggunakan Rancangan Acak Lengkap (RAL) faktorial dengan dua faktor dan empat ulangan. Faktor pertama juvenil infektif (ji) yang terdiri dari 0, 90, 180 , 270 ji dan faktor kedua larva M. plana (M) yang terdiri dari 10 larva intar I, II dan III. Penelitian di lapangan menggunakan Rancangan Acak kelompok (RAK) faktorial dengan dua faktor dan empat ulangan. Faktor pertama terdiri dari 0, 200, 400, 600 ji dan faktor kedua larva M. plana (M) yang terdiri dari instar I, II dan III. Hasil penelitian di laboratorium diperoleh dari ke-3 lokasi pengambilan sampel adalah dari genus Steinernema sp. dan hasil penelitian di lapangan diperoleh mortalitas tertinggi (100%) adalah 3 hari setelah aplikasi dengan kerapatan Steinernema sp. 600 ji.
