Abstract

The purpose of this study to determine the concentration of Streptomyces sp. that able to control pupa the fruit fly Bactrocera sp. up to 50 percent of death and the influence of different concentration Streptomyce to long life and symptoms attacks in the fruit flies pupa Bactrocera sp. This research was carried out on June – August 2017 in the health of plants laboratory of Agriculture Faculty UPN “Veteran” Jawa Timur. The research was carried using of randomized block design with the concentration of Streptomyces sp. 5, 10, 15, 20 and 25. Each treatment is repeated as much as five times. The result obtained is an average of a long life the pupa as a result of treatment Streptomyces sp. accelerating to four to six days. Pupae were successfully hatch into imago a physical disability funds have short life. P arasitic symptoms of fruit flies pupa by Streptomyces sp. were changed become black. Postulate Koch of the fruit flies pupa can be seen with the spore and a distinctive smell of Streptomyces sp.

Abstract

Penelitian Kemampuan Pestisida Nabati (Mimba, Gadung, Laos Dan Serai), Terhadap  Hama  Tanaman  Kubis  (Brassica  Oleracea  L),  dilakukan  di  Green House Fakultas Pertanian Universitas Pembangunan Nasional "Veteran" Jawa Timur.  Bahan  yang  digunakan  ,  tanaman  kubis  (Brassica  oleracea  L),  daun mimba, umbi gadung, Serai, laos, pupuk organik dan anorganik, keberadaan hama secara   alamiah,   pestisida   kimia.   Tujuan   dari   penelitian   ini   adalah   untuk mengetahui efektifitas pestisida nabati yang berasal dari mimba, gadung, laos dan serai terhadap hama yang sering dijumpai pada tanaman kubis ulat grayak (Spodaptera  litura  L), Penelitian ini  menggunakan Rancangan Acak  Lengkap dengan lima perlakuan pestisida yaitu mimba dan laos, mimha dan serai, mimba dan gadung, mimba, serai, laos, gadung, pestisida kimia Reagent, di ulang 5 kali. Tujuan penelitian untuk mengetahui efektifitas pestisida nabati yang berasal dari mimba, gadung, laos dan serai terhadap hama yang sering dijumpai pada tanaman kubis ulat grayak. Hasil penelitian menunjukkan populasi ulat graya (Spodoptera litura L) pada tanaman kubis menunjukkan tidak berbeda nyata (non significant) pada campuran dari pestisida nabati yang dicoba dari masing-masing perlakuan. Sedangkan presentase serangannya mulai dari serangga berat sampai sangat berat, kecuali kontrol yang memakai bahan kimia reagent dengan bahan aktif Tripronil persentase serangganya 11,62% serangga ringan.Kata Kunci : Pestisida Nabati, Kubis,Ulat graya
