Anatomical localization and stereoisomeric composition of Tribolium castaneum aggregation pheromones

TrOn: An Anatomical Ontology for the Beetle Tribolium castaneum

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...

Embryonic patterning mutants of Tribolium castaneum.

The identification and analysis of genes controlling segmentation in Drosophila melanogaster has opened the way for understanding similarities and differences in mechanisms of segmentation among the insects. Homologues of Drosophila segmentation genes have been cloned and their expression patterns have been analyzed in a variety of insects, revealing that the patterns of expression of many gene...

Expanding the genetic toolkit of Tribolium castaneum

Chemical composition of four essential oils from Eupatorium spp. Biological activities toward Tribolium castaneum (Coleoptera: Tenebrionidae)

„ Toxic and repellent properties of whole essential oils from four Eupatorium (Asteraceae) species (E. buniifolium Hook. et Arn, E. inulaefolium Kunth, E. arnottii Baker, and E. viscidum Hook. & Arn) were investigated in different concentrations toward Tribolium castaneum Herbst adults. The essential oils were isolated by hydrodistillation techniques from the aerial parts. The analysis was perf...

Close linkage of eye color genes in Tribolium castaneum.

N the course of linkage studies involving several new mutations affecting eye I pigmentation in the flour beetle, Tribolium castaneum, it became apparent that while being nonallelic to each other and to previously reported eye mutants they were not randomly distributed in the genome. In fact, of the nine eye mutant loci thus far reported, six occur as colsely linked members of three gene pairs....
