FIGURE 2 in Detection, extraction, and collection of eriophyoid mites

FIGURE 2. Schematic drawings illustrating the extraction procedure: a) materials; b) washing phase; c) sieving phase and sieve rinsing; d) sediment collection on a Petri dish; e) microscope observation phase; f) eriophyoid concentration on a filter; g) eriophyoids on a filter; h) sediment collection on a centrifuge tube; i) first centrifugation; j) sieving phase of the tube contents; k) sediment collection on a Petri dish; l) salt solution adding to the sediment of the first centrifugation; m) second centrifugation. Black arrows refer to mite extraction from plant samples and counting; gray arrows refer to mite concentration; white arrows refer to egg concentration.
