1. The composition of the major species in the chestnut grove are shown in Table 1.
2. From the analysis using the law of geometrical progression (MOTOMURA, 1932), it was evident that the composition of the insect community was quite simple in Apeil and complicated community was recognized in May and June.
3. The importnant injurious insects in a chestnut grove in spring were Myllocerus griseus, Lachnus tropicalis, Myzocallis kuricola, Dictyoploca japonica, Anomala rufocuprea.
