COLLECTION AND TEMPORARY STORAGE ☻ Specimens should be collected directly into a mixture of 60% ethyl alcohol (10 pts), glycerine (1pt) and glacial acetic acid ( 1 pt). ☻ In this fluid they remain relaxed and often an adventage when tergal and sternal characters need examining. ☻ Thrips can be kept in this fluid for several months but 60% alcohol is preferable for longer periods of storage ☻ A drop of glycerine added to the alcohol will prevent damage to the insects should the alcohol evaporate

MOUNTING ☻ Specimens should be removed from the collecting or storage fluid and placed in 60 % alcohol for at least 24 hours, then dehydrated through a series of alcohol as rapidly as effective, but with no great changes in concentration; ☻ The time spent in each concentration depends largely on the size of specimens and the thickness of their cuticle. Recommended: 1 h in 70% alcohol, 20 min in 80%, 10 min in 95% and 5 min in absolute, followed by another 5 min in absolute. ☻ Cleared in clove oil for ½ to 10 min, 0r, carboxylol (1 pt and 3 pts xylol) for ½ to 1 min. ☻ Mounted singly, ventral side uppermost, on a cover slip in a drop of balsam

LABELLING ☻ Two label on a good-quality paper and written in permanent Indian ink, should be stuck on each slide ☻ The label should include information on: the locality, the date of collection, the name of collector, description of habitat and plant, reference number to further notes and the name of the mountant. ☻ On the other label should written: The scientific name, including the authority; the name of the person responsible for determination; and further taxonomic and structural details where necessary

DRYING AND STORING ☻ Dry slides in a horizontal position for about a week in a slide oven; ☻ Store slides in a horizontal position in the dark, preferably in wooden slide boxes; ☻ For a quick laboratory check on field infestation, specimens can be displayed adequately by putting them on to a slide in a drop of Hoyers of Barlese fluid, covering them with a cover slip and warming briefly until the are partially cleared
