The objective of this study is to assess the quantitative genetic structure of fitness characters in Tribolium confusum flour beetles. Estimates of genetic variation and covariation for a series of fitness components (two measurements of survival, larval weight, development time, fecundity, and female productivity) were obtained from two populations of T.

Abstract. This study reports the stability of genetically controlled cannibalistic behavior in four strains of flour beetles. The strains were derived from Thomas Park's “Chicago Standard” strain ofTribolium confusum using only three or four generations of brother-sister matings in the mids.

Their use for genetics experiments is somewhat limited by the comparatively lengthy life-cycle. Two species are commonly described: Tribolium confusum —Confused flour beetle.

Tribolium castaneum—rust-red flour beetle. Tribolium castaneum is a small and low maintenance beetle that has emerged as a most sui table insect model for studying developmental biology and functional genetic analysis.

The Tribolium confusum are proper candidates for a study of limiting factors because of the growth time and costs.

The growth period for these beetles is relatively fast. After days of fertilization, the egg hatches into larvae. The larvae last days, and the pupae last around 8 days. These beetles are cheap and easy to examine, due. Abstract.

However, if antagonistic pleiotropy is common, then it also. However, despite significant increases in the availability of molecular markers for the study of genetics in recent years, a significant genetic linkage map for these beetles remains undeveloped.
