Abstract

ABSTRACTInsect parasitoids are small or as large as the host to parasite and off the host. The research was conducted in lowland rice planting area in North Minahasa regency. Research purposes to determine the type and parasitoid populations on rice crop pests in sub Kauditan, Talawaan, and Dimembe. The research was done by sweeping using insect net swing of 20 times on the location of paddy rice crops, sampling is done three times at intervals of two weeks representing all phases of rice growth was identified in the laboratory and then analyzed descriptively. The results showed that the insect parasitoid found was of the Order Hymenoptera and Diptera and in different types and each sub-population, namely, District Kauditan there are 19 types, 19 types Talawaan, and Dimembe13 types. Parasitoids Telenomus spp. average of 6.5 tail in Kauditan, Dimembe 4.5 tail, while the tail Talawaan 3.6 Apanteles sp. average of 6.5 in sub Dimembe tail, Talawaan 6 tails, and tails Kauditan 3.8.Keywords :Parasitoids, Hymenoptera, Diptera, Rice plants

Abstract

ABSTRACTPaddy is the most important staple food in Indonesia, since more than half of the population is dependent on the rice that the paddy plants produce. About 1,75 billion of the three billion Asians, including 210 million Indonesians rely on rice as their primary source of calories. The object of this research is to know the population density and infestation intensity of the paddy bug L. acuta on paddy plants in the North Tombatu, East Tombatu and Pasan Districts of the South-east Minahasa Regency. This research is expected to inform about the population density and infestation intensity of the paddy bug L. acuta in several different places and attempts in controlling it. Results of this research show that the paddy bug has spread in paddy fields over the three districts. The highest population was found in the district of East Tombatu (33,9 individuals / ten double sweeps), followed by the Pasan District (24,1 individuals / ten double sweeps), while the district of North Tombatu had the lowest population (9,2 individuals / ten double sweeps). The high paddy bug population is influenced by environmental factors and farmers’ habits in breeding field paddy plants. The intensity of the paddy bug infestation is already high, so the presence of this pest is highly worrisome.Key words : paddy plants, population density and infestation intensity, paddy bug pest (Leptocorisa acuta Thunb.)

ABSTRACTThe aims of the research is to identify the fungi associated with the death P. xylostella larvae. The research was carried out during 3 (three) months i.e. started from August until November 2012, which is located in the Tomohon City and District of Modoinding. Working procedures of the study include: (1) a collection of the death P. xylostella larvae by taking samples along with cabbage leaves, (2) identification of fungi associated with dead P. larvae xylostella through macroscopic and microscopic observations and isolation on PDA + AB medium by direct plating and dilution. The results showed that there are five species of fungi of the death P. xylostella larvae, namely Hirsutella sp. , Metarhizium sp, Penicillium sp., Fusarium sp., and Aspergillus sp. The species of fungi Hirsutella sp. and Metarhizium sp. including entomopathogenic fungi, while Penicillium sp., Fusarium sp., and Aspergillus sp. may be opportunistic or saprophyte.Keyword: Dead P.xylostella larvae, entomopathogenic fungi, opportunistic fungi

Under Guidence Ir Guntur S.J. Manengkey, MP as chaiman, Prof. Dr. Ir Christina L. Salaki, MS and Ir. Caroulus S. Rante, MS as member.This study aimed to determine the incidence and severity of leaf spot diseases on peanut plants. The experiment was conducted in the Lowian and Lowian One, Maesaan the District of South Minahasa Regency. The duration of the study which lasted for four months from September to December 2013. Research field using survey methods that further observation and communication with the peanut farmer. Furthermore, the distribution plots five sample plots in two different villages to be observed regarding the incidence and severity of disease caused by the cause of the peanut plant. In the laboratory microscopic observation of the shape of conidiophores of the fungus causes leaf spot disease. Things were observed in this study are: (i) symptoms of infected plants leaf spot disease-causing pathogens, (ii) the incidence and severity of disease. Observations in the field showed that the symptoms appear on peanut plants after infection by a disease that causes patches of chlorosis appear later developed into necrosis with an irregular round shape up. This phenomenon is located on the lower surface of the leaves and the leaves, leaf spot color ranging from light brown to brown or yellow halo blackish necrosis.Keywords: incidence, severity, leaf spot disease

ABSTRACT The research aims to determine the population and attacks Cnaphalocrocis medinalis on paddy rice vegetative phase in District East Dumoga, Bolaang Mongondow. Results are expected to be used as consideration in the preparation of pest control strategies C. medinalis on rice crops in the future. Research using survey method in several centers of rice cultivation in the district of East Dumoga Bolaang Mongondow, then set the 3 villages as research locations or as a sampling. Location criteria based on the presence of the rice research under the age of one week. Sampling using Method Diagonal slices and set up five sub-plot. Observations population conducted by randomly selecting ten clump of rice plants in each sub-plot. C. medinalis larvae contained in the leaf roll is taken, and then collected in a bottle containing 70% alcohol. Samples are labeled according to location and time of uptake, later identified in the Laboratory of Entomology and Pest Plants, Faculty of Agriculture, University of Sam Ratulangi. Observations percentage of attacks carried out by observing each of the 200 plants per sub-plot. Clumps were attacked recorded and calculated to determine the percentage of C. medinalis attack. Sampling was performed four times at intervals of two weeks. The results showed that the population of pests C. medinalis varies at different locations and the highest research found in two locations in the village Dumoga which reached an average of 15.33 tail, then in the village Dumoga Three reached an average of 13.66 tail and in the village of Dumoga Four reached an average of 5.33 birds. Observations highest percentage of attacks was found in the village of Dumoga Two sample sites, reaching 10.54%, then the village of Three Dumoga 9.95% and the lowest is Village Dumoga Four reached 1.53%.  Keywords : Cnaphalocrosis medinalis, percentage of attacks and populations
