Flour beetles, Tribolium castaneum, are easy to keep and widely used
as laboratory animals. They consume wheat and other grains while
being adapted to survive in very dry environments. The flour beetles
are major pests in the agricultural industry, in particular cereal silos,
and are highly resistant to insecticides.
An experiment was conducted over 20 generations using different
populations of flour beetles over 20 generations. Using breakfast cereal
as a food source, two different populations of 10 (figure 1) and 100
(figure 2) were studied with each beetle being heterozygous for alleles
b+ and b alleles. The frequency of the b+ allele was measured in the
population after every generation.
