 note = {Damage to beech trunks (Fagus crenata Blume) caused by mulberry borer larvae (Apriona japonica THOMSON) was investigated in the beech forests in Sakae-village, northern Nagano Prefecture. No infestation was found in stands at elevations higher than 800m. However, infestation damage was commonly recognized in stands at elevations lower than 500m. Specifically, the most substantial damage occurred in stands located in areas characterized by heavy snowfalls (i.e. > 2m) as well as in warm-temperate zones (i.e. Warmth Index is > 85 [°C・month])., Article, 信州大学教育学部附属志賀自然教育研究施設研究業績 41: 1-5(2004)},
