Composition of Tribolium confusum cohorts 14 days after egg deposition.

Eggs and the larvae that hatched from them were maintained in different concentrations of diatomaceous earth (DE) and in experimental designs producing different potential for cannibalism. Data represent proportions of the initial egg cohort recorded on a day 14 census as live larvae (L), unhatched eggs (U), dead larvae (D), missing from handling loss (M), and cannibalized (C). Initial cohort composition– experiment 6b: individual eggs, n = 48/DE treatment; experiment 6c: n = 4 replicates of 100 eggs/DE treatment; experiment 6d: n = 3 replicates of 200 eggs, plus 10 virgin adult males or females,/DE treatment. Values are mean ± SE of replicate determinations. Cannibalism estimate means with the same letter do not differ significantly (Tukey multiple comparison adjustment).
