Abstract
Gut pHs of conventional and gnotobiotic maggots of Musca domestica L., Phormia regina (Meigen), Sarcophaga bullata Parker, and Calliphora vicina Robineau- Desvoidy were obtained by micro-electrode. Crop pH is unbuffered and fluctuates with pH of the food which is influenced by microbial activity. However, the 3 regions midgut appear buffered, and their pH is microbe-independent. The fore-midgut is slightly basic in C. vicina, and neutral or slightly acid in the other species. The mid-midgut is most strongly acid in C. vicina, with 2.8 the lowest pH recorded. In order of decreasing acidity are S. bullata, M. domestica, and P. regina. The hindmidgut hovers near neutrality.This publication has 1 reference indexed in Scilit:
