abstract = {Insects show a great variety of mouthpart and muscle
configurations; however, knowledge of their mouthpart
kinematics and muscle activation patterns is fragmentary.
Understanding the role of muscle groups during movement and
comparing them between insect groups could yield insights
into evolutionary patterns and functional constraints. Here,
we developed a mathematical inverse dynamic model including
distinct muscles for an insect head–mandible–muscle
complex based on micro-computed tomography (µCT) data and
bite force measurements. With the advent of µCT, it is now
possible to obtain precise spatial information about muscle
attachment areas and head capsule construction in insects.
Our model shows a distinct activation pattern for certain
fibre groups potentially related to a geometry-dependent
optimization. Muscle activation patterns suggest that
intramandibular muscles play a minor role in bite force
generation, which is a potential reason for their loss in
several lineages of higher insects. Our model is in
agreement with previous studies investigating fast and slow
muscle fibres and is able to resolve the spatio-temporal
activation patterns of these different muscle types in
insects. The model used here has a high potential for
large-scale comparative analyses on the role of different
muscle setups and head capsule designs in the megadiverse
insects in order to aid our understanding of insect head
capsule and mouthpart evolution under mechanical
constraints.},
