Abstract

ABSTRACT   The purpose of this study is to determine the potential of the extracts of leaves and fruit E. agallocha, to the larvae of C. pavonana mortality and to determine the right concentration / dosage extracts of leaves and fruits E. agallocha in controlling of pests C. pavonana. This research was carried out by several phases: 1) exploration of the source plant material extract; 2) Preparation of feed crops; 3) Taking a test insect; 4) Extraction of plant material source extract; and 5) Extracts application. This research was conducted at Plantation Rurukan Village sub district of East Tomohon, Tomohon city for taking the testing insects and feed maintenance ; Laboratory of Microbiology and Plant Pathology, Department of Plant Pests and Diseases, for the extraction of plant material and extracts application in Tomohon and exploration of extracts of plant material sources in the Rerer village sub district of Kombi,  District of Minahasa. The results of the Research are leaves and fruit extract E. agallocha can cause mortality of larvae of C. pavonana. With symptoms of larval mortality after treatment of leaves and fruit extracts of E. agalloca lanta is the larvae colored in yellowish pale then turned into brown to black. E. agalloca leaves and fruit has potential as an ingredient vegetable insecticides to control larvae of C. pavonana with concentration at the level of 0.04% is good at treatment leaf extract and fruit extract treatment as well. Key words: extract E. agallocha, pests C. pavonana, white mustard plants

Abstract

ABSTRACT   The research was aimed to identify parasitoid, to know the morphology characters to count the level parasitisation of parasitoid, to the region of parasitoid distribution and to make a key parasitoid identification. Sampling eggs of H. armigera in order to get a type of parasitoid Trichogrammatidae has carried out in the regencies of Minahasa, South Minahasa and Bolaang Mongondow. Each regency has sampled in three sub-districts for getting the egg samples of H. armigera, which were collected at the age plant of 45-52 days after planting. Sampling result of egg H. armigera has found one type of parasitoid Trichogrammatidae. Based on the identification of parasitoid morphology, i.e: the front wings, antenna, the insect, colors, parasitoid in which parasited the eggs of H. armigera is Trichogrammatoidea sp.. Body color of parasitoid Trichogrammatoidea sp.. was tawny, and the abdominal was more dark. Parasitoid Trichogrammatoidea sp. spread on the planting sub-districts. Parasitization of parasitoid was still low, only ranging from 5.59 to 21.03 percent, the highest and lowest values found in Bolaang Mongondow (Poigar and Bolaang subdistricts). Keywords : type of parasitoid Trichogrammatidae, parasitisation of  parasitoid   ABSTRAK Penelitian bertujuan mengidentifikasi parasitoid, mengetahui karakter morfologi, menghitung tingkat parasitisasi parasitoid, mengetahui wilayah penyebaran parasitoid dan membuat kunci identifikasi parasitoid. Pengambilan contoh telur H. armigera untuk mendapatkan jenis parasitoid Trichogrammatidae telah dilaksanakan di Kabupaten Minahasa, Minahasa Selatan dan Bolaang Mongondow. Setiap wilayah Kabupaten diambil 3 kecamatan untuk pengambilan contoh telur H. armigera. Contoh telur H. armigera dilaksanakan pada umur tanaman 45-52 hst. Hasil pengambilan contoh telur H. armigera telah ditemukan satu jenis parasitoid Trichogrammatidae. Berdasarkan identifikasi karakter morfologi parasitoid yakni sayap depan, antenna, warna tubuh serangga, maka parasitoid yang memarasit telur H. armigera adalah Trichogrammatoidea sp.. Warna tubuh parasitoid Trichogrammatoidea sp. armigera berwarna kuning kecoklatan dan bagian abdomen berwarna lebih gelap.  Parasitoid Trichogrammatoidea sp. menyebar pada semua pertanaman jagung di ketiga wilayah kabupaten.  Parasitisasi parasitoid masih tergolong rendah hanya berkisar antara 5,59-21,03%, wilayah yang tertinggi dan terendah ditemukan di Bolaang Mongondow (di Kecamatan Poigar dan  Bolaang. Kata kunci : jenis parasitoid Trichogrammatidae, parasitisasi parasitoid

Abstract

UTILIZING METODE QUEEN REARING APIS MELLIFERA FOR BEES DEVELOPMENT. This research was conducted in Kumelembuai Village KumelembuaiSubdistrictof  SouthMinahasa Regency that took place from Desember 2012 to January 2014. Completely Randomized Design was used with F test or Kruskal Wallis test. Significant differences were tested using the DuncanTest. Queen Rearing method superior that is Emergency Cell method. Each method consisted of seven treatments with four replicates. The seven treatments were : (a). 200 grams of cane sugar + 200 gram of water, (b). 100 grams of cane sugar + 200 grams of water, (c). 66 grams of cane sugar + 200 grams of water, (d). 200 grams of arenga sugar + 200 grams of water, (e). 100 grams of arenga sugar + 200 grams of water,  (f). 66 grams of arenga sugar + 200 grams of water,  (g). Control. Key  Word :  Apismellifera F., Queen Rearing Method
