Popis: In bags of flour, the founder ♀ Tribolium castaneum Herbst oviposited at a similar rate for most of the 1st generation. This pattern of oviposition was primarily responsible for the consistent oviposition, egg cannibalism, adult eclosion, and adult emigration rates observed throughout each future generation. In the F1 and F2 generations, females emigrated much earlier than founder females severely reducing the number of eggs laid per female.
