The influence of dietary protein quality on midgut and brain proteins in Morimus funereus larvae

Abstract

The response of starved Morimus funereus larvae refed with an artificial diet (Galford, 1967) was examined in the present paper. Larvae were offered diets varying in protein quality (soya protein, casein, and gelatin). Refeeding with the Galford diet (G I) and two modifications of it in which soya protein was supplemented with casein (G II) or gelatin (G III) led to an increase of body mass. Different protein quality in the nutritive substrate influenced both the quantity and quality of midgut and brain proteins.U ovom radu je ispitivan uticaj veštačke dijete po Galfordu (Galford, 1967) i njene dve modifikacije različitog proteinskog sastava (protein soje, kazein želatin) na larve Morimus funereus nakon totalnog gladovanja. Telesna masa larvi se povećala nakon ishrane dijetom po Galfordu (G I), kao i njenim modifikacijama u kojima je protein soje zamenjen kazeinom (G II) odnosno želatinom (G III). Prisustvo proteina različitog kvaliteta u hranljivom supstratu utiče i na kvantitet i na kvalitet proteina srednjeg creva i mozga larvi ove vrste.nul
