Abstract

ABSTRACT Improvements to the identification techniques adapted to the latest determination key, requires socialization, so that the farmer can determine which plant pests have damaged many crops and causing losses. This study were conducted to determine species of fruit fly Bactrocera spp. and to determine the population of Bactrocera spp. attacking commodities chili, tomato and pumpkin siam. Research carried out by direct surveys on the area which is the center of the fruit and vegetable crops in Tomohon. Each stretch of the plants fruit vegetable crops of chili, tomato and pumpkin siam was laid trap.  The number of traps on each observation plots of vegetables or fruit per plant commodities were 5 (five) traps. The bottle trap was placed in the middle of planting vegetables fruit by a diagonal way. Traps of steiner models made of plastic bottles of 1.5 liters of mineral water and a perforated plastic funnel fitted as entrance fruit flies was used in this experiment. The tool is also equipped with a wire as a binder between the traps and wood enforcement to be put in planting fruit vegetables. Cotton was rolled with a diameter of about 3 cm and then tied with thread and put Methyl Eugenol (ME) of 0.25 ml and Cue-Lure (CL) as much as 0.25 ml by using the syringe and then hung in the middle of the bottle trap.

ABSTRACT   Papaya mealybug, Paracoccus marginatus (Hemiptera: Pseudococcidae) in Indonesia was reported attacking papaya in 2008 in Bogor. In North Sulawesi reported attacked papaya in 2009 in Manado. The purpose of research to determine the level of attacks and spreading of  papaya mealybug P. marginatus in North Sulawesi. The study was conducted from December 2010 - September 2011. Dissemination papaya mealybug based on altitude in North Sulawesi, namely: Bitung, North Minahasa, Minahasa, South Minahasa, South Minahasa, Tomohon, and Manado. Papaya plants were attacked by the intensity of the attacks seen low <25%, moderate 25-50% and 50-90% by high. Samples of papaya mealybug brought in the Laboratory Pest and Entomology, Faculty of Agriculture Unsrat Manado to be identified. Results showed papaya mealybug pest infestation has spread over several papaya plantation in North Sulawesi. Papaya mealybug attack papaya covering several areas in the lowlands (<200 m asl) to high area (800 m asl). Spreading pf papaya mealybug attack papaya plantation of Minahasa, Manado, Bitung, Tomohon, North Minahasa and South East Minahasa. Attack rates range of mealbug from low, moderate, and high.

Abstract

Farmer groups are one form of community efforts to live better in the economic field. Thisresearch was carried out with the main objectives: to find out the extent of the effectiveness of the ricefarmer group program in Wolaang Village, East Langowan District, Minahasa Regency, to find out theobstacles in the process of implementing the rice farmer group program in Wolaang and to find out theefforts to overcome the obstacles encountered in the process of implementing the rice farmer groupprogram in Wolaang. The researcher used descriptive qualitative method, data was collected byinterviewing ten informants, observing, and using related documents. The research data is analyzedthrough SWOT analysis which is a strategic planning method used to evaluate strengths, weaknesses,opportunities, and threats in a project or business speculation. The four factors that form the SWOTacronym (strengths, weaknesses, opportunities, and threats). And in the results of the research programthe rice farmer groups in this village have not been effective because 1) have not succeeded in recruitingsmall farmers and communities who have not worked according to the program's main objectives. 2) thereare 10 registered rice farmer groups but only 4 are active due to lack of insight and activities carried out inthe program. 3) Not all members of the rice farmer group are satisfied with the program that has beenmade for a long time because of the lack of supervision and attention of the government so that the ricefarmers prefer to work personally. 4) Supporting facilities are inadequate; Lack of control when workingso that targets are sometimes inappropriate; The report on the use of funds is not very good; Processingland that is still traditional so it takes a long time; The use of funds has not been as needed; Less optimalaccommodation; Weak carrying capacity of citizens to work; Updates to equipment; Circumstances thathinder program mobility; Less than working. 5) the emergence of new farmer groups causes less funding from the government because of the increase in the number of farmer groups; Transfer of farmer groupmembers to new farmer groups; Competition fights for the sympathy of the government and newagricultural land with competitors; and new farmer groups often emerge with a more modern and strongstyle in terms of funding. The suggestions that I can give to Wolaang village farmer groups and theirgovernments are: 1) increasing supervision. 2) pay attention to funding management. 3) increase workmotivation 4) improve the quality and availability of supporting facilities and infrastructure. 5) increasinghealthy competition with beginner farmer groups.Keywords: Farmer Group, Effectiveness, Farmer Group Work Program.

ABSTRACT  The study aims to determine the effect of the concentration of spores of the fungus Beauveria bassiana against Aphis sp insect mortality in the laboratory. implementation of the research carried out for three months from July to September 2014. Research using the method Completely Randomized Design (CRD) with four treatments, using B. bassiana spores concentration of 104, 105, 106 and control. Plants used was pepper plants. Each plant with different spore concentrations, in use ten tail pest Aphis sp. Observations on doing every day for one week, with a look at the mortality of each treatment. The results showed that the test insect mortality was highest at day 4 observation with treatment reaches 106 (80%) at follow treatment 105 (52.5%) and treatment of 104 (0%). Observation day 5 mortality in the test insect reaches 106 treatment (20%), then treatment of 105 (32.5%), and treatment of 104 (10%). The results showed that the test insect mortality was highest at day 4 observation with treatment reaches 106 (80%) at follow treatment 105 (52.5%) and treatment of 104 (0%). Observation day 5 mortality in the test insect reaches 106 treatment (20%), then treatment of 105 (32.5%), and treatment of 104 (10%).

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

ABSTRACKTomato (Lycopersicum esculentum Mill) is no stranger to the community as a tomato vegetable crops play an important role in the nutrition community. This study aims to determine the cause of Fusarium wilt disease and the incidence of disease. This study was conducted in farmers' fields in the village of Tumaratas, Raringis, and Kopiwangker from February to April 2014 This study used a survey method or field observation purposive sampling. Materials and tools used in this study is the tomato crop land, plants Fusarium wilt disease, PDA, CLA media, antibiotics, distilled water, 95% alcohol, petridish, parafilm, test tube, needles ose, spirit lamp, analytical scales, tweezers, cutter, masking tape, autoclave, laminar air flow, rack culture, cover glass, glass objects, microscope, digital cameras, and stationery. The results showed the fungus that causes Fusarium wilt disease infecting tomato plants in the District of West Langowan is Fusarium sp. The incidence of Fusarium wilt disease on tomato plants in the District of West Langowan is Tumaratas village average of 6.16%, the village Raringis average of 8.66%, and the average village Kopiwangker 9.61%. The highest incidence of the disease an average of 13.66% while the lowest incidence of tomato plants with an average of 4.33%.Keywords : Tomato plant, Fusarium sp.
