Zusammenfassung

Die Zahl abgelegter Eier vonTribolium castaneum stieg mit der Verringerung der Partikelgröße der Imaginalnahrung. Sie war maximal bei Weizenmehl und minimal bei unzerkleinerten Weizenkörnern. Die Schlüpffähigkeit der Eier blieb jedoch davon unbeeinflußt.

Effect of particle size of adult food on the reproductive capacity of Tribolium castaneum (Hbst.) (Col., Tenebrionidae)

Abstract

Whole and intact wheat grains or those broken into 2 or 8 equal pieces and supplemented with yeast provided as adult food to individuals ofTribolium castaneum considerably reduced the egg output in these beetles although their larvae were reared on finely powdered yeast-supplemented whole wheat flour. However, egg fertility in all the three dietary situations was 100%.
