The red flour beetle, Tribolium castaneum (Herbst) (Coleoptera: Tenebrionidae) has had a long association with human stored food and can be a major pest in anthropogenic structures used for the processing and storage of grain-based products. Anthropogenic structures are fragmented landscapes characterized by spatially and temporally patchy resources. Here we investigate the ability of female T....

Flour mill fumigations are currently carried out with methyl bromide (MB). By 2005, this gas will be phased out in developed countries because it has been listed under the Montreal Protocol as a substance that depletes the ozone layer. Hydrogen cyanide (HCN) was used as the fumigant of choice for mills in the first part of the last century, and was then replaced by MB. Consequently, it should n...

The pattern of genetic differentiation among experimental populations of the flour beetle Tribolium castaneum suggested the hypothesis that relative fitness of three genotypes at the PGM-1 locus (or other linked loci) depends directly on diet. This hypothesis was tested by measuring several fitness components (developmental time, survival, fecundity, rate of egg cannibalism) on groups of indivi...

The influence of sanitation on responses of life stages of the red flour beetle, Tribolium castaneum (Herbst) (Coleoptera: Tenebrionidae), an economically important pest in flour mills, was investigated in a pilot flour mill subjected to two, 24-h heat treatments. One hundred eggs or 100 adults of T. castaneum were exposed inside each 20-cm diameter by 15-cm high PVC rings holding 0.1-, 0.2-, 1...

Coleoptera (beetles) is a massively successful order of insects, distinguished by their evolutionarily modified forewings called elytra. These structures are often presumed to have been a major driving force for the successful radiation of this taxon, by providing beetles with protection against a variety of harsh environmental factors. However, few studies have directly demonstrated the functi...

In a morphological ontology the expert's knowledge is represented in terms, which describe morphological structures and how these structures relate to each other. With the assistance of ontologies this expert knowledge is made processable by machines, through a formal and standardized representation of terms and their relations to each other. The red flour beetle Tribolium castaneum, a represen...

The study dealt with the effect of alcoholic extract Sesbania sesban seeds and growth regulator Applaud in controlling full phase red flour beetle Tribolium castaneum, as concentrations used for were 0.5, 1.0, 1.5, 2.0%, lowest killing rate was 6.6% at a concentration 0.5% And after 48 hours treatment, while highest reached 93.5% 2.0% treatment compared control sample which no occurred. As beet...

The red flour beetle, Tribolium castaneum, has been selected for whole genome shotgun sequencing in the next year. In this minireview, we discuss some of the genetic and genomic tools and biological properties of Tribolium that have established its importance as an organism for agricultural and biomedical research as well as for studies of development and evolution. A Tribolium genomic database...

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...
