Steatoda nobilis : A comparative study including full body MALDI Imaging and application to Venomics field.

The Noble false widow spider Steatoda nobilis is a member of the
Therididae family, akin the ¿true¿ Black widows of the genus Latrodectus.
Sn is rapidly expanding its geographic range throughout Europe and parts
of the Americas, particularly in and around human dwellings. Sn has also
been shown to be of medical significance in the UK and in Ireland, where
a growing number of severe cases of envenomation has occurred over
the past five years [Dunbar, 2021]. To illustrate the comparison of both
male and female Sn profiles, we additionally present the first whole-body
imaging of a spider using MALDI mass spectrometry. This proof-of concept allows to compare the anatomy of females and males based on
molecular markers (specific m/z distribution on spider slices).
