Summary
The author proposes to standardize the preparation technique for microhymenoptera. The insects have to be presented for identification in a dry state, mounted on a minute pin or glued on a heavy paper point (double-mounting). Preference is given to the mounting on minute pin, as this method has the advantage that a specimen pinned with a minuten may be removed from its support and each morphological detail easily observed. The minuten is fixed to a short strip of soft material such as polyporus (bracket fungus); if this is not available, stiff paper may be used. The support with the pinned specimen is then attached to a pin no. 3 (fig. 1–3). The absence of glue is advantageous, especially in subtropical countries, where the glue is generally destroyed by bacteria and fungi. When the pins are unavailable for this double-mounting technique, the author proposes to glue the thoracic pleurae of the insect to the previously folded tip of a heavy paper point (fig. 6). The material for identification may be preserved in a liquid medium (as alcohol with some drops of glycerine) after a series of individuals have been prepared according to the double-mounting technique. Also, specimens in excess may be sent dry in a plastic or glass tube between two cellucotton masses.
