Antifeedant, Growth Regulatory and Ovicidal Effect of Sambucus ebulus L. Extract on Tribolium confusum Duv.

Aqueous extract from leaves of Sambcus ebulus L. were tested for antifeedant, growth regulation and ovicidal effects against the red floor beetle Tribolium confusum Duv. under laboratory condition (29?1?C, RH 60?5% and 12L:12D). The results indicated a significant deterrence for feeding, and comparatively significant larval, pupal and adult weight decrease in treated vs. controlled insects. Sim...

The Humidity Responses of Tribolium Confusum

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...

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...
