Host stadium specificity in the gregarine assemblage parasitizing Tenebrio molitor.
Reciprocal cross-stadia experimental infections were used to demonstrate stadium specificity within the gregarine assemblage parasitizing Tenebrio molitor, the yellow mealworm. Gregarina cuneata, Gregarina polymorpha, and Gregarina steini are characteristic parasites of larval T. molitor. Gregarina niphandrodes is a characteristic parasite of adult T. molitor. Experimental infections were produ...
متن کاملPhospholipids of Tenebrio molitor larvae
Phospholipids of Tenebrio molitor larvae were separated on columns of DEAE -cellulose and silicic acidHyflo Super Cel. The major phosphatide components were identified by various analytical procedures. Phosphatidyl choline was demonstrated to be the predominant phospholipid with a high percentage of phosphatidyl ethanolamine. A small amount of inositolcontaining phosphatides were present. Phosp...
متن کاملHost specificity among Unionicola spp. (Acari: Unionicolidae) parasitizing freshwater mussels.
Water mites of Unionicola spp. are common parasites of freshwater mussels as adults, living on the gills, or mantle and foot of their hosts and using these tissues as sites of oviposition. The present study addresses specialization among North American Unionicola mussel-mites using 2 measures of host specificity: (1) the number of host species used by a species of mite; and (2) a measure that c...
متن کاملA digestive prolyl carboxypeptidase in Tenebrio molitor larvae.
Prolyl carboxypeptidase (PRCP) is a lysosomal proline specific serine peptidase that also plays a vital role in the regulation of physiological processes in mammals. In this report, we isolate and characterize the first PRCP in an insect. PRCP was purified from the anterior midgut of larvae of a stored product pest, Tenebrio molitor, using a three-step chromatography strategy, and it was determ...
متن کاملDiversity of digestive proteinases in Tenebrio molitor (Coleoptera: Tenebrionidae) larvae.
The spectrum of Tenebrio molitor larval digestive proteinases was studied in the context of the spatial organization of protein digestion in the midgut. The pH of midgut contents increased from 5.2-5.6 to 7.8-8.2 from the anterior to the posterior. This pH gradient was reflected in the pH optima of the total proteolytic activity, 5.2 in the anterior and 9.0 in the posterior midgut. When measure...
