THE NUTRITIONAL REQUIREMENTS OF TRIBOLIUM CONFUSUM DUVAL

I. The Survival of Adult Beetles on Patent Flour and Complete Starvation Diets

B. AUBREY SCHNEIDER 1

1 The Department of Biology, The Johns Hopkins University School of Hygiene and Public Health, Baltimore, Md.

The experimental data set forth in this paper have served to show that:

1. Isolated adults of Tribolium confusum Duval, subjected to conditions of complete starvation upon emergence, or shortly thereafter, will survive up to 26.5 days depending upon the conditions of the experiment.

2. Survivorship of starved adults is shortened and the period of larval development is lengthened by an increase in larval population density.

3. Survivorship of starved adults is significantly longer and the period of larval development is significantly shorter for progeny of 6-months-old parents than for those of one-month-old parents.

4. Survivorship of starved adults is shortened with increasing age.
