Fig. 4. System for measuring holding forces of Archegozetes longisetosus. The test surfaces were fixed horizontally on a stand. The mite was glued to an insect pin and mounted to the strain gage force transducer (FORT25, WPI Inc., USA), which was connected to a micromanipulator. Forces generated by the mites were transferred to the sensor, amplified by the MP100 system (BIOPAC Systems Inc., USA) and recorded with a personal computer and the software AcqKnowledge 3.8.2 (BIOPAC Systems Inc., USA).
