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.

Cocoa pod borer Conomorpha cramerella snellen (lepidoptera: gracillaridae) is one type of the key pest which is highly responsible for drilling cocoa, which then causes the production and quality of cacao to decrease. The use of entomopathogenic fungus is one of the alternatives to cope with it. By invecting and developing within the insect, such a fungus can cause the insect to suffer from diseases which will then be responsible for their death. Beauveria bassiana are types of the entomopathogenic fungus which are used for controlling cocoa pod corer, as they are able to infect the pest trough the enzyme or toxin produced, which then leads to its death. This study aims at an effectiveness test of entomopathogenic fungus Beauveria bassiana against cocoa pod borer. This research was conducted at the Laboratory Udaya University in Bali from May to November 2010. The experimental design employed was randomized complete block design (RCBD) wich was made up of four treatments such as B0 (Control), B1 (B. bassiana in which the spore density was 105 spora/ml/); B2 (B, bassiana in which the spore density 106 spora/ml); B3 (B. bassiana in which the spore density was 107 spora/ml). The result shows that the Larvae CPB which was infected by B. bassiana shows different treatments and responses than control. The fastest death of the larvae CPB took place on the treatments and responses than control. The fastest death of the larvae CPB took place on the treatment of B. bassiana in which spore density 107. The fastest appearance of spore took place on the treatment five days after inoculation. The fungus of B. bassiana at the spore speed of 105 and 107 caused all the larvae CPB 100% to die at five days inoculation.

Until recently the use of synthetic pesticides to control pest and plant diseases proved effective, but on the other hand, the excessive use of synthetic pesticides cause many negative effects, such as the development of pest and disease resistance, second pest explosion, death of natural enemies and pesticide residues in food and environment. One alternative that can be done to solve this problem is the use of botanical pesticides. Botanical pesticides are compounds produced as a plant defence response to disturbances and stimulation. These compounds generally are of secondary metabolites that have many functions, such as growth hormones (Auxin, gibberellins and cytokinins), anti-fungal or anti-bacterial, antibiotics, and toxic to animals and insects. The advantage of botanical pesticides is that they have toxicity similar to synthetic pesticides, but the botanical pesticides can be used to support sustainable organic agriculture. Experiments in the utilization of botanical pesticides to control plant pest have been carried out. One example application is the use of botanical insecticides from “Brotowali” leaf extract (Tinospora crispa) to control the diamond black caterpillars (Plutella xylostella) on cabbage plants. In addition, the use of ‘basil’ oil (Ocimum tenuiflorum) has a real impact in population control of the fruit fly (Bactrocera dorsalis). In addition to pest control, botanical pesticides are also reported to effectively control plant diseases. Use of ‘galangal’ (Alpinia galanga) and papaya (Carica papaya) has a high ability to inhibit the growth of Ceratocystis sp. On PDA and fruits. The combination of ‘betel’ leaf extract (Piper betle) and ‘galangal’ (A galanga) can suppress the growth of banan wilt disease caused by Fusarium oxysporum and / or the Ralstonia solanacearum. The use of ‘galangal’ (A. Galanga) extract with a concentration of 5%, can also inhibit the growth of stem rot disease (F. oxisporum) on vanilla seedlings. In addition, the use of ‘betel’ ieaf P. Bettle in the field can suppress black rot disease on cocoa pods (cocoa black pd disease)

Papaya is one of the many horticultural commodities grown by farmers. In mid-2008, thousands of trees in the District Sukaraga papaya, Bogor Regency pest infestation papaya white and whole tree has been attacked. P. marginatus is a prolific insect that attack several host plants, including tropical fruit crops and ornamental plants. This research aims to determine the spread of lice infestation in White Paracoccus marginatus Ende and type of host plants are attacked by pest Mite White Paracoccus marginatus. This study is useful to obtain information about the spread of pest P. marginatus in the district of Ende as a step in taking control measures, information to relevant agencies and farmer about the existence pf pest P. marginatus in Ende district, and continued research on the existence of natural enemies and pest bioecology O. Marginatus. Sampling study conducted in 21 sub-district in NTT Propinsis Ende. The study was conducted from March-August 2011. Materials used in this study plant pest Paracoccus marginatus, Alcohol 95%. The tools used are a collection of bottles, brushes, a microscope, transparent plastic, paper labels, Thermo-Hygrometer, coo box, stationery and literature. The result showe that the spread of pest P. marginatus was observed in 21 sub-district in Ende found only in the District 2 District East Ende and Ndona. Papaya is attacked by P. marginatus have chlorotic leaves, young leaves to fall and prospective fruits and fruit and leaves are covered by this pest by stacking layers of wax until the drought ends up dead. The intensity of damage caused by pest P. marginatus in the District of East Ende of 33.33% and 16.67% for Ndona District. The spread of pest P. marginatus in the district of Ende found at two locations namely Ende District East and District Ndona. Types of host plants are attacked by pest P. marginatus is Papaya plants.
