Efek Perpaduan Beberapa Tumbuhan Liar Di Sekitar Area Pertanaman Padi Dalam Menarik Arthropoda Musuh Alami Dan Hama

Abstract

<em>This study aims to determine the interest Arthropoda against some wild mix consisting of Chromolaena odorata, Bidens pilosa., Echinochloa Cruss-galli, and Pistia stratiotes. This research is a semi experimental parameters observed were differences in the abundance of arthropods in each observation plot good plot consisting of some combination of wild plants (block refugia) and plot a block away from refugia based on spatial and temporal distribution. Observations using the "visual control" developed Freie and Manhart (1992). Achieved 9 order Arthropoda consists of 32 families were recorded visiting a mix of wild plants, the Coccinellidae, Carabidae, Staphylinidae, Chrysomelidae, Curculionidae, Coenagrionidae, Libellulidae, Tettigonidae, Gryllidae, Acrididae, Mantidae, Syrphidae, Drosophilidae, Tipulidae, Formicidae, Vespidae, Sphecidae, Ichneumonidae, Braconidae, Pyralidae, Papilionidae, Noctuidae, Nymphalidae, Alydidae, Pentatomidae, Reduviidae, Cicadellidae, Delphacidae, Flatidae, Tetragnathidae, and Oxyopidae. The mean abundance was highest in plots dominated by observation block refugia of the family Coccinellidae arthropods that act as natural enemies with a mean abundance reached 29 individuals per day. While the family Reduviidae which acts as a pest has the lowest with a mean abundance value of 1 individual per day. The analysis shows there are 6 families Arthropod natural enemies and pests that show distribution patterns are influenced by the presence of a mix of wild plants (the spatial distribution pattern) and different observation time (temporal distribution pattern), from the family Coccinellidae, Ichneumonidae, Braconidae, Acrididdae, Drosophilidae and Coreidae with a P value <0.05.</em>

Pengaruh Refugia Bunga Telekan (Tagetes erecta) dan Bunga Kertas (Zinnia elegans) pada Populasi Artropoda dan Hasil Tanaman Padi

“…Artropoda diamati secara visual control pada setiap fase pertumbuhan padi. Pada metode ini, serangga yang mengunjungi rumpun padi diamati langsung dari jarak jauh, dengan jarak pengamatan per 2 meter, pada waktu-waktu tertentu (Addina et al 2013). Setiap fase diamati selama 15 menit pada 3 waktu (pukul 08.0010.00, 12.0014.00, dan 15.0017.00).…”

Diversitas dan Asosiasi Tumbuhan Liar pada Lahan Padi (Oryza sativa) dan Jagung (Zea mays) di Unit Pelaksana Teknis Pengembangan Benih Palawija Singosari Kabupaten Malang

“…Akhir-akhir ini, banyak penelitian yang telah menunjukkan bahwa tumbuhan liar memiliki berbagai manfaat dalam proses pengendalian hayati, sehingga dapat dimanipulasi untuk keanekaragaman dan kelimpahan musuh alami. Tumbuhan liar yang lebih disebut sebagai gulma ternyata memiliki potensi sebagai penarik serangga-serangga dan berperan sebagai musuh alami serta dapat berfungsi sebagai proses pengendalian hama pada tanaman budidaya secara alami [3].…”

Temporal Distribution Of Arthropods In Heliotropium indicum In Jombang District As E-Catalog Development

“…The diversity of natural enemies due to the presence of flowering plants (refugia) will lead to the formation of a more stable ecosystem, which in turn will maintain a balance of ecosystem components. According to Addina et al (2013) the presence of wild plants is proven to be able to attract arthropod visits, especially those that act as natural enemies, so that it is a potential effort to increase the number of visits by natural enemies in agricultural land.…”
