Effect of Ration on Energy Allocation in a Carabid Beetle
Preview not available

Abstract

The energy budget of the predatory beetle Notiophilus biguttatus F. has been established at three rations. Rates of egg production, respiration and defecation and the energy value of the faeces increase with an increase in ration. From these parameters we have estimated the amounts of energy that are allocated to reproduction and maintenance.
