ABSTRACT 

The study aimed to determine the population and attacking intensity of Paraeucosmetus pallicornis on rice based on the altitude in South Minahasa regency. Stratified sampling method was conducted consisting of three strata namely 0-300 meters above sea level, >300-600 meters above sea level, and >600 meters above sea level. Sampling was collected by taking the diagonal of each 10 clump at 

different levels of plant age. The results showed that the highest average populations density of P. pallicornis was found at altitude >600 m above sea level. That was equal to 6.46 individuals per clump. In the altitude of 0-300 meters above sea level, average populations density was 6.07 individuals per 

clump. The lowest population was detected at altitude >300-600 meters above sea level which was 6.03 individuals per clump. The attacking intensity of P. pallicornis was the highest at an altitude of 0- 300 meters above sea level that is equal to 25.87 % per clump, followed by the altitude >300-600 meters above sea level which was 24.12 % per clump. The lowest was an altitude of >600 meters above sea level 23.77 % which was per clump.

ABSTRAK 

Penelitian bertujuan untuk mengetahui padat populasi dan intensitas serangan Paraeucosmetus pallicornis pada tanaman padi berdasarkan ketinggian tempat di Kabupaten Minahasa Selatan. Penelitian menggunakan Metode Stratified Sampling yang terdiri dari 3 strata ketinggian tempat yaitu, 0–300 meter di atas permukaan laut (dpl), >300–600 dpl, dan >600 dpl. Pengambilan sampel dilakukan secara diagonal dengan mengambil masing-masing 10 rumpun pada berbagai tingkat umur tanaman. Hasil penelitian menunjukkan bahwa rata-rata padat populasi P. pallicornis tertinggi dijumpai pada ketinggian >600 meter dpl yaitu sebesar 6,46 ekor per rumpun, diikuti ketinggian 0–300 meter dpl mencapai 6,07 ekor per rumpun, dan populasi terendah terdapat pada ketinggian >300–600 meter dpl mencapai 6,03 ekor per rumpun. Intensitas serangan P. pallicornis pada tanaman padi tertinggi ditemukan pada ketinggian 0–300 meter dpl yaitu sebesar 25,87% per rumpun, diikuti ketinggian 300– 600 dpl mencapai 24,12% per rumpun, dan terendah pada ketinggian >600 meter dpl mencapai 23,77% per rumpun.

[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...

Pengaruh Tumpang Sari Tanaman Tomat (Lycopersicum esculentum Mill.) dan Kacang Panjang (Vigna sinensis L.) Terhadap Keberadaan Hama Pada Daun Tanaman

  ABSTRAK ANDI SRI FEBRIANTI (G0111 71 562) “Pengaruh Tumpang Sari Tanaman Tomat ( Lycopersicum esculentum Mill.) dan Kacang Panjang ( Vigna sinensis L . ) Terhadap Keberadaan Hama Pada Daun Tanaman”. Dibimbing oleh Itji Diana Daud dan Melina. Pengendalian secara kultur teknis dengan menggunakan pola tanam tumpang sari merupakan salah satu cara preventif terhadap hama pada daun tanaman. Oleh sebab itu dilakukan penelitian untuk mengetahui pengaruh tumpang sari tanaman tomat ( Lycopersicum esculentum Mill.) untuk melindungi kacang panjang ( Vigna sinensis L . ) terhadap keberadaan hama pada daun tanaman yang dilaksanakan di Dusun Bontonompo, Desa Lassang, Kecamatan Polombangkeng Utara, Kabupaten Takalar, Sulawesi-Selatan, pada November 2020 sampai Februari 2021. Pelaksanaan penelitian dimulai dengan perendaman benih, penyemaian, persiapan lahan, denah perlakuan, pindah tanam, pemasangan ajir dan pemeliharaan. Hasil penelitian menunjukkan bahwa hama yang menyerang tanaman kacang panj...

[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...
