The sugarcane stem borer Phragmatoecia castaneae (Lepidoptera : Cossidae) is a key pest on sugarcane crop in North and West Sumatera. The objective of this research was to study the ability of parasitoid Tetrastichus sp. (Hymenoptera : Eulophidae) on pupa Ph. castaneae H. (Lepidoptera : Cossidae) in the laboratory. This research was carried out at Central Research and Development of Sugarcane Crop Sei Semayang PTPN II Medan from May to July 2012. The method of this research used Randomized Complete Design factorial with 2 factors, the first factor is number of parasitoid (0, 4, 5, 6, and 7 pairs) and the second factor is number of Ph. castaneae (1, 3, 5, 7, and 9 pupa) with three replications. The results showed that the highest percentage parasitisation (100%) on pupa Ph. castaneae was found in treatment 1 pupa with 5, 6, 7 pairs Tetrastichus sp. and the lowest percentage (18,50%) on 9 pupa with 4 pairs Tetrastichus sp. This parasitoid need 10-15 seconds into do copulation. Females of Tetrastichus sp. need 20-25 minutes to put egg into its host. The fastest symptoms in the treatment 1 pupa on 3,47 days and 7 pairs Tetrastichus sp. on 4,73 days, and the lowest in the treatment 9 pupa is 4,47 days. The sex ratio of male and female was 1:3,3. Key words : Phragmatoecia castaneae, Tetrastichus sp, ability of parasitoid.

he influence of the use of plastic mulchs and chili varieties on the attack of antracnose(Colletotrichum capsicii Sydow.) on chili plants (Capsicum annum L.) in the field. The aim of the research was to know the appropriate type of mulchs which could be used to curbthe attack of antracnose and which chili varieties are resistant against antracnose. The researchused Cluster Random Design (CRD) Factorial which consisted of two factors and threerepetitions. The first factor was plastic mulchs: non mulch (M0). silver (M1). and black (M2) the second factor was varieties: Lado F1 (V1). Lembang 1 (V2). Tanjung 2 (V3). The resultshowed that silver black mulch was the best to inhibite antracnose (1.08 %) with Lado F1(1.12%) and the highest on no mulch (7.82 %) with Tanjung 2. Interaction of no mulch andTanjung 2 were lowest (1.70%) and the highest (11.46%) on no mulch and Tanjung 2. Thehighest production (0.72 ton/ha) on silver black mulch with Lado F1 (0.63 to/ha) and the loweston no mulch (0.20 ton/ha) with Tanjung 2 (0.17 ton/ha). Interaction of black silver mulch andLado F1 were highest (0.89 ton/ha) and the lowest (0.15 ton/ha) on no mulch and Tanjung 2. Keywords : plastic mulchs. varieties. antracnose. chili.

The influence of some botanical pesticides for handling grayak caterpillarSpodoptera litura F.(Lepidoptera: Noctuidae) on Deli tobacco. Grayak caterpillar (a kind ofcutworm) is one of an important pest in Deli Tobacco plant which can reduce production. Thepurpose of the research was to know the effectiveness of gadung storage root, babadotan, and castoroil stones with correct dosage in handling grayak caterpillar (S. litura) on Deli tobacco plants. Theresearch was conducted at Institute of Deli Tobacco PTPN II Sampali Medan, from November,2011 until January, 2012. The research used Randomized Block Design (RBD) design of non-factorwhich comprised ten treatments with three control repetitions: the solution of castor oil stones (40,80, and 120 g/l of water), the solution of babadotan (40, 80, and 120 g/l of water), and the solutionof gadung storage root (40, 80, and 120 g/l of water). The result of the research showed that thetreatment of the solution of gadung storage root with the dosage of 120g/l of water was the mosteffective with the lowest percentage of damage intencity (30.00%), the highest percentage of larvamortality (88.33%), and the highest percentage of plant production (11.22g/plot). The ineffectivetreatment was the control treatment with the highest percentage of damage intencity (49.00%), thelowest percentage of larva mortality (1.79%), and the lowest percentage of plant production(4.53g/plot).Keywords: Deli tobacco, botanical pesticides, Spodoptera litura

This researchwas to study to determine resistence of rubber plant genotype against C. cassiicola andC. gloeosporioides at budstock rubber plantation. This research had been conducted atexperimental field of Sungei Putih Rubber Research Center in May-July 2013 using split plotdesign with two factor, i.e genotype plants (930, 135, 38, 51, 65, 100, 108, 118, 222, 223, 227, and374) and diseases type (no disease, C. cassiicola and C. gloeosporioides). The results showed thatthe fastest incubation periode (3 days) contained on genotype 223 and 930, the slowest (6 days) ongenotype 222. The lowest disease severity (20,99%) of C. cassiicola treatment contained ongenotype 100 and the highest (33,33%) was at genotype 65. The lowest disease severity (21,61%)of C. gloeosporioides treatment contained on genotype 222 and the highest (57,41%) was ongenotype 223. The highest total spot (58,56 spots) contained on combination treatment of genotype223 with C. gloeosporioides disease and the lowest (1,70 spots) on combination treatment ofgenotype 100 with C. cassiicola disease.Key Words: Genotype plant rubber, Corynespora cassiicola, Colletotrichum gloeosporioides

The using of parasitoid is the one of way to control the stem borers population whichsafe for environtment and human.The objectives of the research were to study the ability ofparasitoid C. flavipes on larvae of C. sacchariphagus and C. auricilius. The research was held atLaboratory of Sugarcane Research and Development Sei Semayang, Binjai, Medan, NorthSumatera from Mei until July 2013. The method used Randomized Complete Design with threefactors, the first factor was kind of host (C. sacchariphagus and C. auricilius), the second factorwas number of host (2, 3, 4 larvae) and the third factor was method of parasititation (artificial andnatural) with three replications. The results showed that method parasititation significantly effectedthe percentage of parasititation. The highest percentage of parasititation (40,83%) on artificialparasititation and the lowest (27,30%) on natural parasititation. The number of host significantlyeffected sex ratio.
