Abstract

ABSTRACTEntomopathogenic nematodes (EPNs) as biological agents, is consistedSteinernema and Heterorhabditis genus. Steinernema and Heterorhabditis whichbelonged to Steinernematidae and Heterorhabditidae families had closedrelationship to Xenorabdus and Photorabdus as bacterial symbionts respectively(Smart, 1995). Types of soil moisture, temperature, and a host affect thedistribution, survivability, host finding and reproduction of EPNs. To get theEPNs local isolates, exploration of isolates from local areas was needed. Thisresearch was aimed to identify genus and density of EPNs on the fields of corn,soybean and cabbage in Malang Areas and their virulence to the larvae ofSpodoptera litura. Research was conducted at laboratory of pest and disease(Nematological Unit), Plant Protection Department, Faculty of Agriculture,University of Brawijaya, from April to September 2012. EPNs were obtainedfrom corn field in Ngijo village, soybean field in Kendalpayak village, andcabbage field in Bumiaji village. EPNs were isolated from soil samples by usingTenebrio molitor larva. White trap method was used to attract EPNs from Thedead larva of T. molitor and the population of EPNs was counted. EPNs wereidentified based on the symptoms of color changes on the cuticle andmorphological characters. In addition, virulence of EPNs was also tested on the S. litura larva. The result showed that density of EPNs was highest on cabbage field (23.264 EPNs/0.25 ml). Density of EPNs on corn field was 16.976 EPNs/0.25 ml and the lowest density was on soybean field (15.664 EPNs/0.25 ml). Based on the color changes and morphological characters of EPN, on the cabbage field, EPNs were identified as Steinernema and Heterorhabditis and the others, EPNs were identified as Steinernema. Based on the virulence test of EPNs on S. litura larva, there was significant difference between EPNs isolate of corn and othersespecially for 24 hours after application.Keywords: identification, virulence, entomopathogenic nematodes (EPNs),Spodoptera litura

Abstract

ABSTRACTBlast is the oldest disease in the world (Valent, 2004). In 1975 according to Chin, blast could be found in more than 85 countries of rice field include Asia, America Latin and Africa. Blast disease could been decreased rice production up to 70% and it infected all stadia such as leaf, noodle, panicle neck, but seldom found on midrib of leaf. Agrios (2004) proposed that there was structural defenses on leaf surface which was main factor of plant defense. The study aim to determine the resistance of some rice genotypes were tested against leaf blast disease and to determine the influence of leaf tissue characteristic that is epidermal thickness to the leaf blast attack. Based on this research was known that only several rice genotypes showed correlation between epidermal thickness of leaf with intensity of leaf blast attack. The moderate genotypes of rice had a thicker epidermal cells than the susceptible genotypes. The epidermis is one of defenses on rice against leaf blast disease thus strengthness and thickness of epidermal cells would impede a direct penetration of the pathogen or it can’t be penetrated at all (Agrios, 1994).Keyword: leaf blast, structural defense, epidermal thickness of leaf, intensity of

Abstract

ABSTRACTVirginia tobacco (Nicotiana tabacum L.) is an industrial plant with a fairly higheconomic value in Indonesia. One constraint of t tobacco cultivation is a disorderdiseases such as mosaic disease that caused by Tobacco Mosaic Virus that canreduce yields and degrade leaf tobacco (Semangun, 1996). One effort to produce a healthy business is tobacco fertilization. The dose and ratio of NPK fertilizer can squeeze vulnerability and increase the resilience of crops to diseases, especially diseases of TMV in tobacco. Implementation of the research began in January- May 2012 in the greenhouse and the laboratory of plant pathology, Faculty of Agriculture University of Brawijaya Malang. The research was carried out using a complete randomized design (RAL) are composed of two factors with treatment 4 concentration (0%, 0,3%, 0,5%, 1%), and 3 the number of the application (1x, 2x, 5x). Each treatment was repeated three times. From all leaf fertilizer application and the amount of leaf fertilizer liquid, the concentration ratio of 0.3% with 2x the number of applications on a 7 day time interval indicates the weight of wet leaves on the highest of 95,467 grams of dried leaves with weights of 11,430 grams.Key words : Virginia tobacco, Tobacco Mosaic Virus, Leaf fertilizer liquid

Abstract

ABSTRACTThis research was aimed to study the population, attack intensity of bagworm (M. plana) and it parasitoid on oil palm plantations. Sampling was conducted 4 times in blocks 1-9 Afdeling OK PT. Lestari Tani Teladan, Donggala, Central Sulawesi from August to October 2012. A systematic sampling method was used to observe M. plana population from each observation point. There were two stages of M. plana such as larvae and pupae. Both stages were checked their conditions to clarify their parasitoids. In addition, parasitoids were observed especially at fourth observation. Result showed that population of M. plana larva decreased during observation period (from August to October 2012). Opposite condition was occurred that population of pupa increased in same period of observation. Highest population of M. plana was recorder on third and fourth block of plantation. Number of parasitized pupae directly proportional to total of pupae (R2=0,95). Populations of parasitoid have not been able to control pests M. plana naturally. Some parasitoids were identified such as Brachymeria sp. (34%), Eurytoma sp. (13%), Entodoninae (17%), Tetrastichus sp. (24%), Tachinidae 9% and two species of Phygadeuontinae 2% and 1% for each.Key words: bagworm, Metisa plana, parasitoid, oil palm
