Abstract

Salah satu hama yang menyerang tanaman jagung yaitu ulat grayak (Spodoptera frugiperda) yang merusak tanaman jagung.  Salah satu upaya pengendalian S. frugiperda yaitu penggunaan insektisida nabati, seperti biji sirsak (Annona muricata) yang dilarutkan dalam pelarut organik.  Penelitian ini bertujuan untuk mengetahui pengaruh aplikasi ekstrak biji sirsak dengan tiga jenis pelarut terhadap mortalitas dan perkembangan S. frugiperda.  Penelitian ini dilakukan di Laboratorium Bioteknologi dan Laboratorium Ilmu Hama Tumbuhan, Fakultas Pertanian, Universitas Lampung.  Penelitian ini disusun dengan rancangan acak kelompok, yang terdiri atas 4 perlakuan dan 5 ulangan.  Perlakuan terdiri atas: (1) kontrol, (2) aplikasi ekstrak biji sirsak dengan pelarut akuades konsentrasi 2%, (3) aplikasi ekstrak biji sirsak dengan pelarut metanol konsentrasi 2%, dan (4) aplikasi ekstrak biji sirsak dengan pelarut heksan konsentrasi 2%.  Dalam penelitian ini terdapat 20 satuan percobaan, pada setiap satuan percobaan digunakan 10 ekor larva S. frugiperda instar II.  Data pengamatan dianalisis menggunakan uji F dan uji lanjut menggunakan Beda Nyata Jujur dengan taraf 5%.  Hasil penelitian menunjukkan bahwa ekstrak biji sirsak dengan tiga jenis pelarut mempengaruhi pekembangan dan mortalitas larva S. frugiperda. Pembentukan pupa dan imago yang normal menjadi menurun.  Ekstrak biji sirsak dengan tiga jenis pelarut juga menyebabkan menurunnya stadium larva, pupa, dan imago, serta lama hidup S. frugiperda.  Ekstrak biji sirsak pelarut heksan serta metanol mempunyai daya hambat makan (antifeedant) kategori kuat larva S. frugiperda.  Ekstrak biji sirsak pelarut heksan menyebabkan mortalitas larva S. frugiperda pada 6 hari setelah aplikasi lebih tinggi (94%) daripada dengan pelarut akuades (56%).

Abstract

Swibawa IG, Oktavia T, Dhona AR, Hariri AM, Efri E. 2022. Diversity and abundance of arthropods on canopy of chili and eggplant crops in Pringsewu, Lampung. In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-10 Tahun 2022, Palembang 27 Oktober 2022. pp. 154-165. Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).Chili and eggplant were two famous vegetable crops in Pringsewu Lampung and their cultivation practice were intensively using synthetic mulch, inorganic fertilizer, and synthetic pesticides, that may affect to arthropods communities. The purpose of this research was to study diversity and abundance of arthropod community inhabited canopy crop of chili and eggplant in Pringsewu, Lampung.  Sampling of arthropods by yellow sticky trap and ground cloth methods on 4, 6, and 10 weeks after planting of chili and eggplant crops were conducted in district of Adiluwih, Pringsewu, province of Lampung on May until August 2022.  Identification of arthropods into taxon of family was done in Plant Pest Laboratory, University of Lampung. The result show that the abundance of arthropod that indicated by total individual that were caught were 905 on Chili and 1399 on eggplant respectively.  Taxonomic diversity of arthropod on chili were 8 order, 34 families with Shannon index of 2.38 and Simpsons Index of 0.84, while on eggplant were 8 order and 32 families with Shannon Index of 2.58 and Simpsons Index of 0.89. The functional groups of arthropods on Chili consisted of 14 families of herbivore and 20 families of non-herbivore, while on eggplant there were 14 families of herbivore and 18 families of non-herbivore arthropods. Base on Sorenson Index, the similarities of arthropods communities on chili and eggplant was 0.76. Diversity and abundance of arthropods both on chili and eggplant was higher on 6 than 4 and 10 weeks after planting crop old. Total individual of herbivore arthropods was higher than non-herbivore.
