Late-instar larvae, pupae, and adults of Tribolium castaneum (Herbst), the red flour beetle, or Tribolium confusum (DuVal), the confused flour beetle, were exposed for variable durations at 36–54 1C. Beetles were placed in laboratory ovens set at a baseline of 27 1C, the temperature was increased by 0.1 1C per minute until the target temperature was achieved, and beetles were then held for spec...

Matrix-Assisted Laser Desorption/Ionization Mass Spectrometric Imaging (MALDI-MSI) has developed as a useful tool in generating comprehensive metabolite profiles along with spatial information model organisms. The ability of MALDI-MSI to generate situ whole organisms or specific tissue sections serves an efficient alternative solvent extraction protocols, especially for the identification biomo...

Beetles (Coleoptera) are the most diverse animal group on earth and interact with numerous symbiotic or pathogenic microbes in their environments. The red flour beetle Tribolium castaneum is a genetically tractable model beetle species and its whole genome sequence has recently been determined. To advance our understanding of the molecular basis of beetle immunity here we analyzed the whole tra...

The consequences of pearling and cutting (barley Hordeum vulgare L.), and roasting and cutting (buckwheat Fagopyrum esculentum Möench) on the development and food consumption of the confused flour beetle Tribolium confusum Duv. were studied. The factors affecting the increase in the T. confusum population, and food consumption effectiveness (the proportion of wasted food in the whole amount of ...

The insect mushroom bodies play important roles in a number of higher processing functions such as sensory integration, higher level olfactory processing, and spatial and associative learning and memory. These functions have been established through studies in a handful of tractable model systems, of which only the fruit fly Drosophila melanogaster has been readily amenable to genetic manipulat...
