Abstract: X-ray imaging provides fascinating insights into the morphology of
insects. KIT's synchrotron X-ray microtomography facility is one of the fastest
in the world, enabling scanning of large numbers of insects in a single
experiment. High-throughput X-ray microtomography experiments have demonstrated
the value of the method for the digitization and 3D analysis of large
scientific collections of extant and fossil specimens. The presentation will
highlight recent results, including fossil parasites, peculiar mandibles in
minute wasps, and a comprehensive repository of ant morphology. Further
methodological developments are driven by the need to increase the dose
efficiency of X-ray imaging as required for in vivo studies. In this context,
we have developed an imaging system based on Bragg crystal optics. Its
potential was demonstrated by visualizing the behavior of live parasitoid
Trichogramma wasps inside their host eggs during the approximately one-hour
emergence phase. Despite advances in X-ray imaging, the analysis of insect
micro-CT data remains tedious and timeconsuming. In particular, manual
segmentation of large and complex datasets remains a significant bottleneck,
especially for large-scale comparative studies. I will show how the open source
platform Biomedisa ("Biomedical Image Segmentation App") can be used for
semi-automatic segmentation of insect micro-CT data to speed up the process and
provide more accurate results than traditional manual segmentation approaches.
