| description | <p>Rice spacing can affect the species and populations of insect pests. The closer spacing of rice are suitable for the habitats and niches of insect pests. This research was aimed to observe the community of insect pest on rice planted with various spacing regime. Field experiment was carried out on a-15 hectare rice field grown using various rice spacing: ‘tegel’ (25 cm x 25 cm) and legowo cropping of 4:1, 5:1, 6:1, and 7:1. Insect pests were collected using insect nets. All the insects found at a rice season were 27 species. The dominant species at vegetative stage of rice were <em>Oxya chinensis </em>(Thunberg), <em>Acrida turrita </em>(Linnaeus), <em>Nilaparvata lugens </em>(Stål), <em>Nephotettix virescens </em>(Distant),<em> </em>and <em>Cofana spectra </em>(Distant), whereas at generative stage the dominated ones were <em>Leptocorisa acuta</em> (Fabricius) and <em>Riptortus </em>sp. The populations of <em>N. lugens</em> and <em>N. virescens</em> were not proven to be affected by rice spacing. The population of the both planthoppers were low and they did not become a key pest at fresh swamp ecosystems. The key insect pests was <em>L. acuta </em>and its population were affected by the rice spacing. The population of <em>L. acuta</em> was higher at rice with a more dense spacing, those were legowo cropping of 6:1, 7:1, and ‘tegel’ compared to legowo cropping of 4:1 and 5:1. Therefore, legowo cropping of 4:1 or 5:1 should be applied at the fresh swamp ecosystems to decrease the insect pests population.</p> |
