Abstract

The study aims to assess the biological studies of red rust red flour beetle Tribolium castaneum on wheat flour. The present investigation was conducted in the Department of Entomology, College of Agriculture, Indira Gandhi Krishi Vishwavidyalaya, Raipur (C.G.) during, 2011–2012. The stock culture of Tribolium castaneum was initiated by collecting the adult beetles from the infested wheat grains from NSP (National seed project) store house. After the appearance of larvae observation were taken up to the pupal formation. In this way larval and pupal period of the test insect was computed. Before the larval appearance period was computed as incubation period. After pupal formation it was observed daily for the appearance of adults as well as its longevity. Developmental period (Egg to adult) was recorded by counting the number of days taken from egg laying to emergence of adult. Biology of T. castaneum on wheat flour was studied under laboratory condition at temperature range of 30° C to 35° C and 70 to 75 per cent relative humidity. The incubation period was completed in 6 days, while larval and pupal period was completed in 10 and 6 days, respectively. Life cycle from egg to adult emergence of T. castaneum was completed in 22 days. Longevity of adults with and without food was recorded with an average of 55.5 days and 10.5 days, respectively.
