Abstract: Spodoptera frugiperda merupakan hama utama tanaman jagung dengan persentase serangan 30-60%. Larva S. frugiperda bersembunyi dibagian paling susah untuk dijangkau oleh pestisida, lebih sering ditemukan di daun tanaman jagung yang masih menggulung. Tujuan penelitian ini untuk mengetahui efektivitas ekstrak Tithonia diversifolia sebagai insektisida nabati guna mengendalikan larva S. frugiperda di laboratorium. Penelitian menggunakan Rancangan Acak Lengkap Faktorial terdiri 2 faktor perlakuan yaitu dosis nanopartikel bioinsektisida T. diversifolia dan stadia larva. Perlakuan nanopartikel bioinsektisida terdiri dari 6 taraf, yaitu : P0- = tanpa perlakuan (kontrol), P0+ = pestisida Curacon 500 EC (bahan aktif : Profenos 500 g/l) dosis 1 ml/l, P1 = nanopartikel bioinsektisida T. diversifolia konsentrasi 4%, P2 = nanopartikel bioinsektisida T. diversifolia konsentrasi 6%, P3 = nanopartikel bioinsektisida T. diversifolia konsentrasi 8%, P4 = nanopartikel bioinsektisida T. diversifolia konsentrasi 10%. Stadia larva terdiri dari 2 taraf, yaitu : S1 = larva stadia 3, S2 = larva stadia 5. Parameter yang diamati yaitu perubahan mortalitas larva, persentase feeding, persentase pupa dan imago terbentuk, imago cacat. Hasil penelitian menunjukkan bahwa nanopartikel bioinsektisida T. diversifolia dapat mengendalikan larva S. frugiperda. Pemberian nanopartikel bioinsektisida T. diversifolia dengan konsentrasi 10% (P4) dapat mengendalikan Spodoptera frugiperda dengan mortalitas 33,33% dan persentase feeding 30,67%. Persentase mortalitas larva S. frugiperda tertinggi (60%) terdapat pada perlakuan P4S1 (konsentrasi 10% pada larva stadia 3). Terbentuknya pupa dan imago terendah dengan aplikasi nanopartikel bioinsektisida T. diversifolia pada perlakuan P4S1 sebesar 40 %. LC50 adalah 9,98% nanopartikel bioinsektisida T. diversifolia dan nilai LT50 adalah 6,10 hari. Pemberian nanopartikel bioinsektisida T. diversifolia dengan konsentrasi 10% dapat mengendalikan S. frugiperda pada larva stadia 3 di laboratorium. Spodoptera frugiperda is the main pest of maize with an attack percentage of 30-60%. S. frugiperda larvae hide in places where pesticides are most difficult to reach, more often found in the curled leaves of corn plants. The purpose of this study was to determine the effectiveness of Tithonia diversifolia extract as a vegetable insecticide to control S. frugiperda larvae in the laboratory. The study used a factorial completely randomized design consisting of 2 treatment factors, namely the dose of T. diversifolia bioinsecticide nanoparticles and the larval stage. The nanoparticle bioinsecticide treatment consisted of 6 levels, namely: P0-= no treatment (control), P0+ = Curacon 500 EC pesticide (active ingredient: Profenos 500 g/l) dose 1 ml/l, P1 = T. diversifolia bioinsecticide nanoparticle concentration 4% , P2 = 6% concentration of T. diversifolia bioinsecticide nanoparticles, P3 = 8% concentration of T. diversifolia bioinsecticide nanoparticles, P4 = 10% concentration of T. diversifolia bioinsecticide nanoparticles. The larval stage consisted of 2 levels, namely: S1 = larval stage 3, S2 = larval stage 5. The parameters observed were changes in larval mortality, feeding percentage, percentage of pupae and imago formed, imago defects. The results showed that T. diversifolia bioinsecticide nanoparticles could control S. frugiperda larvae. The administration of T. diversifolia bioinsecticide nanoparticles with a concentration of 10% (P4) can control Spodoptera frugiperda with a mortality of 33.33% and a feeding percentage of 30.67%. The highest percentage of S. frugiperda larvae mortality (60%) was found in the P4S1 treatment (10% concentration in stage 3 larvae). The lowest pupa and imago formation with the application of T. diversifolia bioinsecticide nanoparticles in the P4S1 treatment was 40%. The LC50 was 9.98% nanoparticles of T. diversifolia bioinsecticide and the LT50 value was 6.10 days. Administration of T. diversifolia bioinsecticide nanoparticles with a concentration of 10% can control stage 3 S. frugiperda larvae in the laboratory.
