A Modular System of 3D Printed Emergence Traps for Studying the Biology of Shot Hole Borers and Other Scolytinae.

A modular system for studying the biology of Scolytinae using 3D printed emergence traps is presented. This system consists of traps that can be used for the introduction of beetles into trees as well as for the determination of the number of offspring emerging from trees and branches, and their production of frass and sawdust. Open-source files used for printing these traps have been deposited as supplementary material and can be downloaded for trap production by students of Scolytinae with access to a 3D printer. The cost in material for the production of a single emergence trap on the printer used here is approximately $1.30, with a print time of less than 90 min.
