[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...

[JURNAL] Dinamika Populasi Hama dan Penyakit Utama Tanaman Jagung Manis (Zea mays saccharata Sturt) pada Lahan Basah dengan Sistem Budidaya Konvensional serta Pengaruhnya terhadap Hasil di Denpasar-Bal

 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...
