• Experiments were carried out to examine the effect of various diets and mating on the egg-laying habit and phototaxis of the black carpet beetle, Attagenus megatoma at 30℃, 50〜60 per cent R.H. Duration of the pre-oviposition period of four days was not affected by the kind of diet and mating. In the continuous pairing, the duration of net-oviposition period of the adults given with water or honey were prolonged more than those of the adults deprived of food, but an increase in the oviposition period was only noted when the adults were given honey in the limited pairing. In the continuous pairing, the duration of the post-oviposition period was seven to eight days except the adults fed on honey. Unmated female did not deposit eggs, but some individuals deposited unfertillized eggs when fed on honey. When water was given, there occurred a significant increase in fecundity, and when given honey there was a further increase as compared with unfed adults in both continuous and limited mating. However, in limited pairing, adults deposited less eggs than those of continuous pairing in all cases, repeated pairing is therefore necessary for the attainment of full potential fecundity. Effects of water and honey upon the increment of the life span except the males of limited pairing that were given water were significant in all cases. Change of response to the light occurred earier in unmated adults than in mated ones. Reversal of phototactic response occurred a few days earlier in the female than in the male. When honey was given, and in most cases, water supply increased the duration of negative response as compared with those deprived of food. Egg laying curves shown by the adults provided with the same kind of food are almost the same regardless of the duration of pairing. From the results described above discussions were made on the status of Attagenus megatoma from the viewpoint of adaptation to the indoor life by marking a comparison of the ovipositional habit among dermestid species. It was concluded that Attagenus megatoma is in a transitional process of adaptation to the indoor life.
