On the Seasonal Prevalence of the Smaller Rice Leaf Miner (Hydrellia griseola FALLEN) in the Southern Part of Ibaraki Prefecture. Shizuyuki IWAMOTO (Ibaraki Agricultural Experiment Station, Mito) Jap. J. appl. Ent. Zool. 10: 110-114 (1966) The seasonal prevalence of the smaller rice leaf miner was observed in the southern part of Ibaraki Prefecture in 1965-1966. In winter, all the developmental stages of the smaller rice leaf miner were found on the gramineous weeds. They occur abundantly in wet places where the weeds grow well during winter. The development of the insects at all stages continued even in winter. The pupae were found on dead leaves and leaf-sheaths of the weeds, and could develop when the dead leaves and leaf-sheaths were sunk under the water. The seasonal prevalence of the adult investigated by net sweepings was plotted as a curve with eight peaks late in January-early in February, mid-April, mid-May, mid-June, late in July, late in August-early in September, mid-October, and late in November-early in December. This indicates the fact that this insect repeats eight generations per year in this area. The above results was supported by the results of repeated dissections of the weeds collected in the field. Continuous rearing experiments made in the laboratory also showed eight or nine generations per year. This insect attacked the rice plant only in the period from late April till mid-June, and thereafter shifted to weeds.
