Sprinkler-irrigated rice yields the same as irrigated lowland rice but requires less water. The goal of this study was to describe the pests of this crop. The results of examinations made on the stem, leaves, and panicles of rice plants, and of the soil by soil traps, are as follows: root pests were the black cricket (Melanogryllus desertus Pallas), bulb mite (Rhyzoglyphus echinopus Fumouse-Robin), and elm leaf aphid (Tetraneura ulmi Linnaeus). Stem and leaf pests were springtail (Tomocerus plumbeus Linnaeus), yellow springtail (Bourletiola lutea Lubbock), leaf bettle (Lema melanopus Linnaeus), corn gound beetle (Zabrus tenebroides Goeze), red sprider mite (Tetranychus urticae Koch), cereal spider mite (Bryobia graminum Schrank), green grain aphid (Schizaphis graminum Rodani), grain aphid (Macrosiphum avenae Fabricius), and barley flea beetle (Phyllotreta vittula Redtenbacher). Stem and panicle pests were the meadow mouse (Microtus arvalis Pallas) and hare (Lepus cuniculus Linnaeus). Zabrus tenebroides Goeze was detected as a panicle pest as well. The abundance and species composition of insect pests depended on crop rotation. Tetraneura ulmi and Rhyzoglyphus echinopus were present during all seasons when rice followed maize, but these pests were absent with systematically repeated irrigation. Insect damage situations could occur in all cases but the individual density of pests decreased with periodic irrigation, although irrigation was not always effective.
