The bulb scale mite (Steneotarsonemus laticeps (Halbert)) is occasionally an important pest causing of forced narcissus bulbs and is probably widespread in many stocks. Although rarely causing extensive damage to bulbs growing in the field, it is of concern to those who grow the crop for export. Other plants attacked are hippeastrum, eucharis, Sprekelia and Vallota. The mite belongs to the family Tarsonemidae, which includes other important plant pests, e.g. the cyclamen mite (see page 338) and the strawberry mite (see page 366).
