BACKGROUND Stigmaeids mites have been recorded only on Phlebotominae sand flies up to now. Five species of Eustigmaeus, and three of Stigmaeus were reported on infested sandflies in different country up to the present. METHODS Sand flies collection was done using CDC light trap and sticky paper. The mites were isolated from infested specimens, mounted in Puri's medium and identified using rel...

The average internode lengths and their variability frequently differs not only between colonies but also between stolons of a single colony. The differences are therefore unlikely to be genetic ones. Occasionally much longer internodes occur (up to 8 mm...
