Tytuł: Lipid content and energetic equivalent as a measure of reproductive effort in two species of Tribolium

Abstrakt:

Comparison was made between two ways of estimation of reproductive effort using relationships between progeny and the parental female. Both lipid content and energetic value yield consistent results of reproductive effort differences both between instar groups and between different species. The cost of maturation and eclosion was calculated as based on the loss of energy or lipid content. This cost is higher in 7-instar groups (over 55%) and it is true for both sexes in the two species.
