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 (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....

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...

J. Econ. Entomol. ii: 1144-1148 (1984) ABSTRACT Seed oils of many sapindaceous plants contain substantial amounts of cyanolipids. Several of these oils stimulated aggregation of the sawtoothed grain beetle, Oryzaephilus surinamensis (L.), and the confused flour beetle, Tribolium confusum (Jacquelin duVal). In a pitfall bioassay, they attracted the sawtoothed grain beetle and the rice weevil, Si...

Hard red winter wheat was treated with pirimiphos-methyl at 4, 6 and 8 mg kg(-1), synergized pyrethrins at 0.38, 0.75, 1.13 and 1.5 mg kg(-1), and combinations of the two insecticides, to conduct laboratory bioassays against four beetle pests of stored grain, red flour beetle Tribolium castaneum (Herbst), rusty grain beetle Cryptolestes ferrugineus (Stephens), lesser grain borer Rhyzopertha dom...

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...

Sex determination cascade in insects terminates with the production of sex-specific protein, Doublesex (Dsx). We identified the dsx homolog (Tcdsx) in Tribolium castaneum. The pre-mRNA of Tcdsx is sex-specifically spliced into three female (Tcdsxf1, Tcdsxf2 and Tcdsxf3) and one male-specific (Tcdsxm) isoforms. Cis-regulatory elements potentially involved in sex-specific splicing of the Tcdsx pr...
