“…Schoenly et al (2003) reported densities of 318-747 individuals/m 2 during the early stages of plant growth and 256-490 individuals/m 2 when seed heads were forming, in rice fields of Laguna Province, Philippines. Mugica et al (2006b) documented 14 families of invertebrates in rice fields of Sur del Jíbaro, Cuba, during the cultivation cycle, with crustaceans being most abundant (5 kg/ha).…”

Rice fields host a large diversity of arthropods, but investigating their population dynamics and interactions is challenging. Here we describe the modification and application of a leaf blower-vac for suction sampling of arthropod populations in rice. When used in combination with an enclosure, application of this sampling device provides absolute estimates of the populations of arthropods as numbers per standardized sampling area. The sampling efficiency depends critically on the sampling duration. In a mature rice crop, a two-minute sampling in an enclosure of 0.13 m 2 yields more than 90% of the arthropod population. The device also allows sampling of arthropods dwelling on the water surface or the soil in rice paddies, but it is not suitable for sampling fast flying insects, such as predatory Odonata or larger hymenopterous parasitoids. The modified blower-vac is simple to construct, and cheaper and easier to handle than traditional suction sampling devices, such as D-vac. The low cost makes the modified blower-vac also accessible to researchers in developing countries.

“…Distribusi serangga secara spasial maupun temporal berkaitan erat dengan siklus hidup, karakteristik morfologi jenis,dan kondisi klimatik pada saat jenis tersebut memilih habitatnya selain waktu mencari mangsa, reproduksi dan pengenalan inang (Schoenly et al, 2003) Tabel di atas merupakan nilai hasil analisis variansi dan regresi yang menunjukkan perbedaan nyata pada tiap pola distribusi, baik itu pola distribusi spasial maupun pola distribusi temporalnya. Haasil analisis yang tertulis pada tabel di atas menunjukkan familifamili Arthropoda yang pola distribusinya dipengaruhi oleh keberadaan perpaduan tumbuhan liar yang digunakan dalam penelitian ini.…”

<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>
