"Food consumption, defecation, assimilation and production were studied in three species of bibionid larvae (Bibio marci, B. pomonae, Penthetria holosericea) feeding either on leaf litter or their own excrements. Assimilation efficiency of larvae feeding on leaf litter was in all species higher then assimilation efficiency of the same species feeding on their own excrements. Larvae reared on excrements also lost weight, which indicated that excrements were insufficient as an exclusive source of energy. In B. marci, P. holosericea the effect of temperature on assimilation efficiency was studied. In P. holosericea assimilation efficiency decreased with increasing temperature. This trend was not observed in B. marci. B. marci was fed on pure cellulose to test if cellulose can serve as the only source of energy. Mortality of larvae feeding on cellulose was significantly higher than of those feeding on leaf litter and did not differ from starving larvae." . "RIV/60077379:_____/05:00024702" .
