Stored products are among the most important foods in human nutrition. However; these under pressure of many harmful organisms.One pests is Tribolium confusum Jacquelin du Val. (Coleoptera: Tenebrionidae). In this study, effects two essential oils (Mentha rotundifolia and Satureja calamintha) an enthomopathogenenic fungi on has been tried laboratory conditions, contact repellent effect dry plan...

the essential oils of aerial parts of three medicinal plants artemisia khorassanica podl., rosmarinus officinalis l. and mentha longifolia l. were isolated by hydrodistillation and investigated for their toxicity and repellency against tribolium confusum jacquelin du val. at 27 ± 1 ºc and 60 ± 5% rh in darkness. the mortality of the adults increased with concentration from 185 to 1111 μl/l air ...

Structural heat treatment, a viable alternative to methyl bromide fumigation, involves raising the ambient temperature of food-processing facilities between 50 and 60 degrees C by using gas, electric, or steam heaters, and holding these elevated temperatures for 24 h or longer to kill stored-product insects. A dynamic model was developed to predict survival of mature larvae, which is the most h...

VERDOMINANCE for viability of newly arising mutant polygenes has been reported by several investigators in the past decade in Drosophila melanogaster and Tribolium confusum [WALLACE 1957, 1958, 1959, 1963; BURDICK and MUKAI 1958; MUKAI 1961; MUKAI, YOSHIKAWA, and SANO 1966; CRENSHAW 1965 (in radiation-induced mutations). MUKAI, CHIGUSA, and YOSHIKAWA 1964, 1965; MUKAI and YAMAZAKI 1968 (in spon...

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...

medicinal plant powders have traditionally been used as grain protectants against stored-product insect pests. in this study, insecticidal activity of carum copticum l. and cuminum cyminum l. powders was assessed on adults of sitophilus granarius l. and tribolium confusum jacquelin du val. experiments were carried out on wheat at 27 ± 1 ºcand 55 ± 5% r. h. the mortality increased with increasin...

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...
