From field observations and laboratory experiments, it was estimated that the fecundity and the survival rate of the smaller brown planthopper, Laodelphax striatellus FALLEN, may be remarkably higher in the early seasonal and the earlier cultures of rice plants in comparison with those in the common spring habitats, such as weed lands, grass, wheat and barley fields, because the former was more suitable as food to the planthopper and accompanied with a lower level density of Araneid spiders preferably attacking the planthopper. Thus, the early seasonal and the earlier cultures of rice plants seem to provide a habitat
