FLAX-SEED MITE. (Tyroglyphus sp.; Order, Acarina.) Diagnosis.—An increasing quantity of fine debris or dust in the bin or box containing the flax-seed. On close examination, many microscopic, whitish, moving insects. Description and Life-history.—This flax-seed-eating mite closely resembles the common flour and cheese mite, but is probably a different species. Mites may be distinguished from other minute insects by their having four pairs of legs instead of three, as with true insects. The Flax-seed Mite is white and soft, and is so small that many of them together re- semble fine, white dust. They occasion- ally occur in immense numbers in bins of flax-seed in warehouses or elevators. One correspondent reports them as several inches deep on the floor of an old bin. In the infested bins there will be seen a Fig. 26.

It is probable that the mites attack only broken or partially decaying seeds. Remedies.—There is to be found almost always associated with this Flax-seed Mite another slightly larger mite (Clieyletiis sp.) which preys upon it, and does much to reduce the numbers of the pest. If these other mites are present, they will probably suc- ceed in practically exterminating the Flax-seed Mite in the course of a few weeks. The burning of sulphur in the infested building is recommended. If the mites are confined to one or two bins, bi-sulphide of carbon should be introduced, as recommended in case of Angoumois Grain Moth (p. 50), remembering the highly inflammable nature of the Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - col
