Abstract

The confused flour beetle (Tribolium confusum Duval) and Mediterranean flour moth (Ephestia kuehniella Zeller) have long been recorded as serious pests of stored grain products (Riley. 1839, Chittenden 1896). In recent years they have served as very valuable material for laboratory experiments on insect nutrition (Chapman 1924, Richardson 1926). In spite of the economic and scientiric importance of these two insects the writer could find little detailed information on their growth and development under carefully controlled conditions of temperature and relative hunidity, on a normal whole weat diet. This investigation is a study of the growth and development of Tribolium confusum Duval and Ephestia kuehniella Zeller at a temperature of 30° C. and 73% relative humidity.
