“…The number Arthropods species found was more than 50 species in IPM system of rice field. However, the arthropod samples in the study were caught by using four kinds of trap: yellow sticky, light trap traps, insect nets and pitfall trap (Samharinto, Abadi, Raharjo, & Halim, 2012). In this research sites, pesticides were used 2-4 times during the rice growth in each plot of the study.…”

Arthropods biodiversity on a rice ecosystem plays an important role related to the pest management. This research aimed to investigate the diversity and community structure of arthropods in the rice ecosystem. It was conducted in Lembah Seulawah, Aceh Besar Regency, Indonesia from February to August 2016. Sweep net was used to collect insects on four rice plots at 35, 45 and 55 days after transplanting (DAT) as vegetative, transition and generative stages respectively. The result showed that the twenty-five morpho-species found at vegetative stage was the highest among the three stages. They were categorized as phytophagous insects, spiders, predatory insects, parasitoid, and neutral insects. Each arthropod's category the highest among the three stages was in the higher abundance at vegetative stage, except for phytophagous arthropod. The Shannon-Wiener diversity index (H') was significantly higher at vegetative stage than those at remaining stages, while Simpson Dominance (C) and Species Evenness (E) indices were not significantly different among the three observed stages.

“…Shannon-Weiner Diversity Index also involves species richness and evenness and is equal to the sum of the log transformed relative proportions weighted by its corresponding proportion multiplied by negative 1. Species diversity is high when the value is >three, medium when the value is between one and three, and low when the value is <one (Samharinto et al, 2012). The effective number of species is the antilog of Shannon-Weiner Diversity Index and provides an actual measure of biodiversity in terms of the number of equally abundant species (Jost, 2006).…”

This study investigated the floristic composition and diversity of weeds in organic rice fields in Langkong, Mlang, Cotabato covering an area of 2.5 hectares within which 100 quadrats were randomly assigned. Identification of weeds showed thirteen species belonging to six families eight of which are annuals and five perennials comprising five broadleaf, three grass, and five sedge types. All weed species had <50% uniformity which may imply less competitiveness against rice or effective control by weed management practices. Fimbristylis littoralis and Cyperus difformis have the highest frequencies and the highest field uniformities and highest mean field densities indicating that these weeds are the most difficult to control. The weed density of fields in which the species occurred increased compared to densities from all fields for all weed species that may mean that site-specific or management-specific factors contribute to the survival of those species. Relative abundance values showed that Fimbristylis littoralis and Cyperus difformis are the two most dominant weed species. Weed species diversity is medium and equivalent to 5 equally abundant species.

“…Penggunaan pestisida sintesis masih dilakukan oleh petani yang tanpa di sadari juga mengganggu keseimbangan dan kestabilan ekosistem sehingga perlu dipikirkan untuk mencari penggantinya. Disamping itu penggunaan pestisida pada persawahan untuk pengendalian OPT menunjukkan penurunan kelimpahan musuh alami hama (parasitoid dan predator), seperti hasil penelitian Samharinto et al (2011) pada pertanaman padi sawah. Salah satu cara pemanfaatan musuh alami (pengendali hayati) sebagai pengendali hama pada tanaman dalam rangka membuat lingkungan atau ekosistem lestari.…”

Telah dilakukan penelitian keanekaragaman arthropoda dan kelimpahan musuh alami pada empat jenis tanaman refugia pada bulan Mei-Juli 2020. Keanekaragaman ditentukan dengan indeks keanekaragaman (H’) (Shannon-Wiener) dan kelimpahan musuh alami ditentukan dengan menghitung jumlah individunya. Hasil penelitian menunjukkan nilai indeks keanekaragaman spesies tertinggi dengan waktu penangkapan dan fase yang berbeda, pada bunga kenikir pada fase sebelum berbunga pada jam 16.00-17.00 (H’=2,92), berbunga muda pada bunga marigold jam 09.00-10.00 (H’=2,57) dan berbunga tua juga pada bunga marigold jam 09.00-10.00 (H’=2,23), sedangkan indeks keanekaragaman spesies terendah adalah bunga matahari pada fase sebelum berbunga pada jam 16.00-17.00 (H’=0), berbunga muda pada bunga kenikir jam 12.00-13.00 (H’=0,46) dan berbunga tua pada tanaman bunga matahari jam 16.00-17.00 (H’=0,64). Indeks keanekaragaman spesies tertinggi secara keseluruhan pada fase sebelum berbunga adalah bunga kenikir (H’=2,80), kemudian fasel67 berbunga muda yang tertinggi adalah bunga marigold (H’=2,82) dan fase berbunga tua yang tertinggi juga pada bunga marigold (H’=2,73). Kelimpahan musuh alami secara keseluruhan ditentukan dengan menghitung jumlah yang tertangkap. Pada bunga kenikir predator sebesar 35 dan parasitoid sebesar 96 individu, kemudia pada tanaman bunga kertas predator sebesar 20 dan parasitoid sebesar 22 individu, sedangkan pada tanaman bunga marigold predator sebesar 67 dan parasitoid sebesar 52 individu serta pada tanaman bunga matahari predator sebesar 18 dan parasitoid sebesar 0 individu.
