oa Journal of the Entomological Society of Southern Africa - The effect of temperature on the growth and development of a South African strain of the hide beetle Dermestes maculatus Degeer (Coleoptera: Dermestidae)



At constant temperatures of 20, 25, 30, and 35�C, the incubation periods ranged from 6,7 to 2,1 days, the larval periods from 43,9 to 20,8, the prepupal periods from over 10 to 4, and the pupal periods from 11,1 to 6,0 (no pupae formed at 20�C). Females kept at 35 �C laid fewer eggs (mean 605) than those kept at the lower temperatures (1129-1464). Egg mass was inversely related to temperature (0.33 mg at 20 �C, 0,18 mg at 35�C).
