Nutritional Studies on the Confused Flour Beetle, Tribolium Confusum Duval
The confused flour beetle (Tribolium confusum) was chosen for this study because it lives in a food which ordinarily contains no living organisms. The death rates are greater in cultures which are handled daily than in those which are not handled but when all are handled alike the results are comparable. The results from experiments with individual beetles in various kinds of flour were plotted...
متن کاملDigestive proteolysis organization in two closely related Tenebrionid beetles: red flour beetle (Tribolium castaneum) and confused flour beetle (Tribolium confusum).
The spectra of Tribolium castaneum and T. confusum larval digestive peptidases were characterized with respect to the spatial organization of protein digestion in the midgut. The pH of midgut contents in both species increased from 5.6-6.0 in the anterior to 7.0-7.5 in the posterior midgut. However, the pH optimum of the total proteolytic activity of the gut extract from either insect was pH 4....

in this research, fumigation efficiency, repellency and persistence of citrus essential oils extracted from dried peels of orange, bitter orange and mandarin (cultivars: satsuma, page, clemantin) were investigated against adults of confused flour beetle tribolium confusum duval. the essential oils were extracted by using clevenger apparatus. 40 ml glass container as bioassay chamber and filter ...
متن کاملeffect of teflubenzuron, hexaflumuron and pyriproxyfen compounds on nutritional indices of confused flour beetle, tribolium confusum duval (col.: tenebrionidae)
abstract confused flour beetle, tribolium confusum duval (col.: tenebrionidae) is one of the most important stored product pests of flour in iran. in this research the effects of insect growth regulators (igrs): teflubenzuron, hexaflumuron and pyriproxyfen were studied on larval and imago nutritional indices of confused flour beetle. the results showed that they were more effective on relative ...
متن کاملThe Humidity Responses of Tribolium Confusum Jacquelin Duval in Wheat Flour, Sand, and Air
Larval and adult Tribolium confusum were tested in flour and sand substrates at various relative humidities, ranging from 10% to 90%. Both life stages preferred a flour environment of from 10% to 50% relative humidity. In sand, however, the insects selected more humid environments. Investigations of survival in sand, flour, and air environments indicated that two factors may be operating in the...
