| Outline of Final Research Achievements |
Pyrgus maculatus is a grassland butterfly belonging to Hesperiidae and one of the most apprehensive species about extinction in Japan. I investigated the relation between the field burning and the ratio of bare ground in the meadowland which P. maculatus inhabited Kiso Town and the oviposition condition of P. maculatus inhabiting the slope face of the terraced fields in Takayana City. It is considered that female seeks to lay eggs on the low and little leaves of food plants with the high ratio of bare ground, which were maintained by farmer's management. The cycle of the field burning and the meadow in every two years was considered to provide the grassland environment which was suitable for the lifestyle. It seemed that these relations were the coexistence mechanism between their inhabiting and human land use. Total effective temperature constant, developmental zero, the critical day length of diapause and artificial mating method were clarified. And survey in Korea was carried out.
