Abstract

ABSTRACT   This study aims to determine the biological of Sitophilus oryzae and S. zeamais which includes development stadia, life cycle, long life, fecundity, mortality and sex ratio. Research using descriptive and substitutional methods. The research conducted in the laboratory of Entomology and Plant Pests and Pest Department of Pest and Disease Faculty of Agriculture Sam Ratul;angi University Manado. The results showed differences in the life cycle, long life and fecundity between S. oryzae and S. zeamais. Long life cycle and life imago S. oryzae shorter than S. zeamais. The life cycle of S. oryzae is 35.22 days and S. zeamais 49.13 days. Life long female imago S. oryzae 101 days and 88.75 days males, S. zeamais females and males 109.25 125.75 day day. Fecundity of S. oryzae lower than S. zeamais namely S. oryzae average 152.8 points and S. zeamais average of 203.0 points. Pradewasa mortality and sex ratio of S. oryzae and S. zeamais unchanged at S. oryzae 80.5% and 0.79, S. zeamais 77.0% and 0.77. Keywords: Sitophilus oryzae, Sitophilus zeamais, development stadia, life cycle, long life,  fecundity, mortality

Abstract

ABSTRACT The problem in postharvest pests must be handled seriously since recent research were not comprehensively resolved it. Sitophilus oryzae was a major pest and serious problem on post harvest products. The reseach aimed  to develop a life table of S. oryzae on rice. The life table is a part of life history that consists of important information about the living organism. This information can be used for predicting population growth. By developing life table database, information on mortality, life expectancy, and the development ability of S. oryzae can be obtained. Results showed that mortality index of eggs was 0.4;  larvae was 0,54, and pupae was 0,32, and adult was 1,0. Life expectancy index of eggs was 1.65; larvae was 1.42; pupae was 1.51 pupae; and adults was 1.0. One female was able to give rise 32.56 females or 58.57 males and females of the next generation. Keywords : Life table, Sitophilus oryzae,  mortality index,  life expectancy

Abstract

ABSTRACT   The research objective was to test a variety of cabbage cultivation techniques is the use of organic fertilizers, botanical insecticides, and multiple croping. This research was conducted in the Village Paslaten Tomohon. When the study was conducted from January 2011 to January 2012. In this experiment, each treatment than control would be sprayed with Barringtonia asiatica extract with a concentration of the best based on laboratory test results. The parameters observed were percentage of attacks, cabbage production, analyzes the advantages of organic and non-organic cultivation. These experiments using randomized block design (RBD) Orthogonal contrast with eleven (11) treatment and four (4) test. The results showed that the highest percentage of attacks on fertilizer treatment mitraflora+ B. asiatica 37.5%. While the lowest was 7.14% peasant patterns. Cabbage production was highest in treatment patterns farmers are 6.84 tons / ha. Low on fertilizer treatment mitraflora 4.44 tonnes / ha. Analysis for cropping farming Organic Cabbage with R / C = 1.91 and B / C = 1.07. Patterns of farmers with a value of R / C = 1.91 and B / C = 1.1. Keywords: Production, percentage attack, multiple cropping, cabbage ABSTRAK Tujuan penelitian adalah  menguji berbagai teknik budidaya tanaman Kubis yaitu penggunaan pupuk organik, insektisida botanis, dan multiple croping.  Penelitian ini dilaksanakan di Kelurahan Paslaten Kota Tomohon. Waktu penelitian dilaksanakan dari bulan Januari  2011 sampai dengan Januari 2012.  Dalam percobaan ini, setiap perlakuan selain kontrol akan disemprot dengan ekstrak Barringtonia asiatica dengan konsentrasi yang terbaik berdasarkan hasil uji di laboratorium.  Parameter yang diamati meliputi persentase serangan, produksi kubis, analisis keuntungan budidaya organik dan non organik.  Percobaan ini menggunakan Rancangan Acak Kelompok (RAK) Kontras Ortogonal dengan sebelas (11) perlakuan dan empat (4) ulangan. Hasil penelitian menunjukkan bahwa, persentase serangan tertinggi pada perlakuan pupuk mitraflora + B. asiatica 37,5%. Sedangkan terendah adalah pola kebiasaan petani 7,14 %. Produksi kubis tertinggi pada perlakuan pola kebiasaan petani yaitu 6,84 ton/ha. Terendah pada perlakuan pupuk mitraflora 4,44 ton/ha. Analisis usaha tani untuk pola tanam Kubis Organik dengan nilai  R/C = 1,91 dan B/C =1,07.  Pola kebiasaan petani dengan nilai  R/C = 1,91 dan B/C =1,1. Kata kunci : Produksi, persentase serangan, pola tanam, kubis
