Beetles are the largest insect order, with Tribolium castaneum as the first species with a completely sequenced genome; beetles may now be new candidates for model organisms in various studies. Almost a quarter of all known types of animals are beetles, with approximately 400,000 species constituting almost 25% of all known animals and occupying most environments on the planet. Micro-CT is a key tool for future research on beetles to increase our knowledge of the functioning of insect organisms and to help provide significant practical implications for biomedical applications, environmental monitoring, and/or food production.
X-Ray Microscopic Imaging of a Beetle
This month we imaged a beetle using the SkyScan 1275 high-speed desktop micro-CT. Our most straightforward and easiest instrument to use, the SkyScan 1275 is a great match for quickly imaging small samples like beetles and other insects.
As shown in Figure 2, the SkyScan 1275 micro-CT captured the fine internal structures of organs and muscles with an isotropic voxel size of 15 µm. A high-density substance appears to be present in the abdomen of the beetle based on the saturated brightness of this region.
When looking through the 3D view of the beetle, we can utilize a maximum intensity projection (MIP) view to highlight the densest regions of the sample (Figure 3). In this case, the densest regions are the muscle structures in the torso and the contaminant within the abdomen of the specimen.
In examining the internal morphometry of the beetle, the SkyScan 1275 did an excellent job at highlighting individual structures from the internal anatomy of the specimen (Figure 4). For specific regions of interest, the dataset could be pared down further to isolate any points of interest.
The SkyScan 1275 is an extremely capable instrument at our lowest entry cost and excels for high-speed imaging of many samples. While other instruments within our portfolio may offer improved resolution, the SkyScan 1275 also offers high resolution, powerful datasets for many sample types.

These scans were completed on our high-speed desktop SkyScan 1275 micro-CT system at the Micro Photonics Imaging Laboratory in Allentown, PA. Reconstructions were completed using NRecon 2.0 while visualization and volumetric inspection of the 2D and 3D results were completed using DataViewer and CTVox.
