Brontispa longissima Gestro (Coleoptera: Chrysomelidae) is one of the important pests that attack the palm plants in Southeast Asia. There is a reported decline in the productivity of palm plants when the pest attack reaches 30-40% with 5% of the plants attacked dying. B. longissima pest attacks plants at all stages of life, but its attack is most prevalent when plants reach the age of 4-5 years. The spread of pest B. longissima has ben reported in the district of Ende, Nangakeo and Ndona in 13 villages with a total area of the severe intensity of attacks. There have been attempted control measures with the release of natural enemies Tetratichus brontispae but not much success has be seen. This study aimed to find out: The dominant type of parasite in the district of Ende. T. brontispae were propagated and maintained in the laboratory using augmentation techniques, conservation or disposal was to be done. Colonies of the propagated parasite T. brontispae were then released in the field. The factors causing T. brontispae control failure, the population of B. longissima in the field, possibly the need for augmentation or conservation of T. brontispae and the right time to make the release of the parasite in the field was important. This research is expected to be useful as a basis in formulating and appropriate control program, in order to control the pest B. longissima in the field. The experiment was conducted from January to June 2010 at Nangakeo, Ndona and Ende district. Implementation of the research was divided into four stages: location survey, maintenance and multiplication of the pests B. longissima and T. brontispae parasite, parasite release and the evaluation of the result. The result was; that there are three types of parasites, B. longissima coconut leaf pest in Ende (sub Ndona, Nangakeo and Ende) the eggs of the parasite Trichogrammatoideanana spp., the larvae and pupae of the parasite Trichogrammatoideanana spp. and the ‘Asecodeshispinarum Boucek’. T. brontispae parasite being the most dominant parasite in each district with 10% level of larvae and pupae of 60-90%, biased sex male : vemale ratio. The pest capability of T. brontispae parasite in the laboratory was 6: 10 with a success rate of 90 %. The decline in the influence of parasite performance was unsynchronized between phases from the phase of the insect host-parasite in the field, the availability of insect host and time of release as well as climatic conditions not being conductive.

This research conducted to know the biological responses of leaf miner parasitoid Liriomyza huidobrensis is Hemyptarsenus varicomis Girault (Eulophidae), Opius sp (Braconidae) and Gronotoma micromorpha (Eucoilidae). Three species of parasitoid chosen as the substance of research caused by biological agent superiorities. On this research, there are some observed that is long life imagoes, preoviposition, oviposition period, after oviposition, The egg-laying rate, fertilization, daily fertilization, mortality and female proportion. This research was conducted for four-month at Ecology Laboratory and Insect Systematics and at the Green House of Pest and Plant Diseases Department, Faculty of Agriculture Udayana University in Denpasar. Used substance of host kidney bean (Vigna sinensis L ) host insect ( L. Huidobrensis ) and species of the parasitoid (H.varicornis, Opius sp and G.micromorpha) The experiments using randomized complete block design was used in this research. The observed results indicated that betwen three species of parasitoid used H.varicornis has preoviposition period and time after oviposition shortest so that to reproduce generation of H.varicornis faster than G.micromopha and Opius sp. At the meantime the fertilization level, and best female proportion produced of H.varicornis. Mortality on G.micromorpha and O.liriomyzae cause of paralyzing and host- feeding by H.varicornis. Mortality on G.micromorpha and Opius sp influential to female proportion number that produced that is the mortality of female generation caused of paralyzing and host-feeding by H. varicornis, So that fertilizing level, parasitisation level and female proportion higher happen if G.micromorpha or Opius sp released after releasing H. varicornis

Title: Increasing of Cocoa Production through the Application of Healthy Cocoa Technology in the "Wonga Mengi" Farmer Group in Kedebodu Village, South-Ende District, Ende Regency, East Nusa Tenggara Province. Kedebodu Village is located 12 km from the capital city of Ende Regency, which is part of the population earning a living as a cocoa farmer. The average land area of cocoa farmers is ± 2 ha/person with average productivity of 140 kg/ha which is very far from the ideal cocoa potential of 1,150 - 2,000 kg/ha. This condition is caused by the age of cocoa plants that are no longer productive, lack of care and high levels of pests and diseases. The service activity aims to increase the knowledge and skills of cocoa farmers in applying healthy cocoa technology so that the production of cocoa plants, especially in the "Wonga Mengi" farmer group in the village of Kedebodu, can be increased. The method used is participatory in the form of field schools by providing material and its application directly in the garden. There are two main program activities, namely providing direct assistance in the form of superior cocoa seedlings in the form of cuttings or entries and pruning tools as well as providing assistance in the application of healthy cocoa technology. After mentoring for about 4 months, it is known that there is an increase in farmers' knowledge about the application of healthy cocoa technology by an average of 72.22% and skills by 67.5%. Until now there has been an increase in fruit volume both in quantity and quality, which is shown by an increase in the number of ovaries/trees (36.68%), the number of fruits/trees (20%), and the dry weight of seeds/trees (30.2%). With this service, an increase in the knowledge and skills of the "Wonga Mengi" farmer group in implementing healthy cocoa technology has an impact on increasing cocoa production.

Training on Agro Eco-System Analysis for Cassava Farmers in Plant Pest Organism Management Techniques. Pest population fluctuations in cassava plants tend to increase and spread rapidly in drought fields and a monoculture cropping pattern with close spacing therefore the presence of pests planted is highly dependent on agro-ecosystem conditions. Therefore ecological-based pest control is very necessary. To maintain the stability of the plant ecosystem, basic skills are needed in conducting agroecosystem analysis (AESA). Based on the analysis results obtained recommendations for appropriate ecosystem management for each growing season and facilitate farmers in determining good cultivation techniques regarding pest control, cropping patterns, soil and water conservation as well as natural enemies that are appropriate for their plants. AESA activities are carried out so that farmers understand and are skilled in managing their cassava plantations because Randotonda Village is a producer of "Nuabosi" cassava which is known as a regional superior product. The activity is carried out in a participatory manner by directly involving the participating farmers as observers, fact seekers and decision-makers for the management of their agroecosystems through discussion and manifesting current real conditions with the hope that in the future they can manage their cropping agroecosystems properly. The highest increase in farmer understanding occurred in natural enemy components of 91.67% while the average increase in farmer understanding for all agro-ecosystem components was 57.14%. All participants were able to perform AESA very well which was indicated by the ability of farmers to make recommendations for managing cassava agroecosystems for the next planting season.
