ABSTRACT 

Rice crops is included into the family of Graminae that produces seeds from China. Rice  Plant is the crops that produce rice, consumed approximately by 90 % from the whole  citizens of Indonesia as the main food. White pest(Nymphula depunctalis Guene) is one of  pests that attacks rice crops in Indonesia. This research aims to find out the population and  intensity of the attack of N. depuntalis pest. The research took place in sub-district of East  Dumoga, regency of Bolaang Mongondow, which was in three villages, that is Imandi,  Mogoyunggung and Tonom, and the execution time was from July to Desember 2013. This  research used the survey method done in rice field belonged to farmers, each village was  taken three observation plot, and determined of five sub observation plot to be observed.The  materials and tools used were rice crops planting, killing bottle, indicator, insect net, insect  collecting bottle, label paper, plastic bag, plastic rope, bamboo, pair of scissors,camera and  writing tools. The research result shows that white pest (N. depunctalis) has been spread on  the rice in three villages in sub-district of East Dumoga with the population average value of  2,16%. The highest pest population was found in Village of Mogoyunggung that is 2,93 pests  on average, and then in village of Tonom with 2,28 pestsand the lowest population was found  in village of Imandi with the average of 1,28 pests, while the attack intensity is still classified  into the low one in sub-district of East Dumogathat is 10,33%.

[JURNAL] Keanekaragaman Serangga pada Bunga Tomat (Lycopersicon esculentum Mill.) di Lahan Pertanian Organik

MOSI RETNANI FAJARWATI, TRI ATMOWIDI, DAN DORLY Departmen Biologi, Fakultas Matematika dan Ilmu Pengetahuan Alam Institut Pertanian Bogor (diterima Juni 2009, disetujui Agustus 2009) ABSTRACT Insect Diversity On Tomato Flowers ( Lycopersicon esculentum Mill .) in Organic Agriculture. Study on the diversity of insect visitors on tomato flowers were conducted at Bina Sarana Bakti (BSB) organic farm, Cisarua, West Java. Diversity of insects were observed by observational method, an 10 m2 area of tomato plants in the morning, mid-day, and afternoon. Observations were conducted during 20 days. Diversity of visiting insects were analyzed by Shannon diversity and its evenness. Similarity of visiting insects between time of observations were analyzed by Jaccard similarity index. In organic farm, insect visitors of tomato plants consist of six orders belonging to eight species. Insect visitors of tomato flowers were dominated by Thrips sp. (Thysanoptera) and Hylaeus sp. (Hymenoptera). Hylaeus s...

 SALBERD FERDINAN RONDO1*) , I MADE SUDARMA2 , DAN GEDE WIJANA2 ABSTRACT  Dynamics of Pest Population and Main Diseases of Sweet Corn Plants (Zea mays saccharata Sturt) at Wetland with Conventional Cultivation System and Their Effect on Yields in Denpasar-Bali. The study was conducted using survey techniques of pests and diseases in paddy fields belonging to farmers in DenpasarBali, which consists of three fields. The three areas were Sidakarya, Renon and Kesiman. Plant samples in each land were taken using the sample plot diagonal method, with the area of diagonal plot in each land was 3 m x 3 m. Plot observations on each of the specified area of plant samples was done randomly (lottery) as much as 25% of the total number of plants per-plot, then observation was done for population growth of pests and diseases, temperature, humidity and crop yield. The observations was started from 1week old plants after planting (MST) to 1 week before harvesting, with intervals of 1 week. Re...
