Haemolymph sugar homeostasis and the control of the proventriculus in the honeybee (Apis mellifera carnica L.)
The proventriculus regulates the food passage from crop to midgut. As the haemolymph provides a constantly updated indication of an insect’s nutritional state, it is assumed that the factor controlling the proventri-culus activity is to be found in the haemolymph. The purpose of this doctoral …

Tissue- and Development-specific Expression of Proton-mediated Peptide Transporters in the Developing Chicken
… PepT1, PepT2 and PHT1 mRNA expression in the proventriculus, duodenum, jejunum, ileum, ceca, large intestine, brain, heart, bursa of Fabricius, lung, kidney, and liver in layer chicks on embryonic days 18 and 20 and days 1, 3, 7, 10, and 14 post-hatch. Absolute quantification real-time PCR was …

Effects of pelleting millet-based diets on the performance of broiler chickens
… PM on the carcass characteristics, gizzard and proventriculus as well as the cost efficiency of broiler production were determined. Results from this study revealed that PM grains had higher (P<0.05) CP, fat and essential amino acids content compared to maize grains. Pelleted diets had higher …

Nutritional Ecology of the Carpenter Ant Camponotus pennsylvanicus (De Geer): Macronutrient Preference and Particle Consumption
… compacted into pellets. It is thought that the proventriculus contains such particles in the foregut, where they are eventually filtered from the ingluvium. Microspheres 1 μm or less were difficult to observe in the infrabuccal pocket, suggesting that they are not as effectively sequestered as …

Diet analysis of wintering waterfowl in the Southeastern United States in relation to ecoregion, habitat, and guild
… the Mississippi Flyway region. The esophagus, proventriculus, and gizzard of each specimen were removed, dried, and sorted for statistical analysis. Multiple two-way ANOVAs were run to test the effects of ecoregion, habitat, and guild on total mass and diet mass in waterfowl. A difference …

Tissue Distribution of a Peptide Transporter mRNA in Sheep, Dairy Cows, Pigs, and Chickens
… was 1.9 kb. Other tissues, including the crop, proventriculus, gizzard, ceca, liver, kidney, and muscles showed no hybridization to the probe. In conclusion, mRNA for a peptide transport protein(s) is present in the small intestine of all animals examined and the omasal and ruminal epithelium of …

Spatial and Temporal Immune Response in House Flies in Response to Ingestion of Bacillus Cereus and Eschericha Coli 0157-H7
… and Diptericin at 2 and 6 h PI in the midgut and proventriculus. This study shows that B. cereus elicits a strong immune response from the house fly and can persist in the gut until 24 h PI, while E. coli O157:H7 elicits little immune response and can persist up to 12 h PI. These findings help to …

Taxonomy, phylogeny, and zoogeography of the weevil genus Euops (Insecta: Coleoptera: Curculionoidea) in the Papuan Region
… of the mouthparts, the metanotum, and the proventriculus are useful in phylogenetic reconstruction and in the diagnosis of species groups. These and other characters are described for the first time. Methods for their appropriate preparation and examination by SEM and light microscopy are …
