If the plant is not too large, it may be possible to set it in the sink and give it a syringing with water under pressure. If this syringing is done at regular weekly intervals, it may be possible eventually to rid the plant of scale insects or to lessen the population to a considerable Fig. 7a (left)—Tiny scale insects (magnified) are usually orange, gray brown, or black. Fig. 7b (right)—Some scale insects are most trouble on ferns and foliage plants. Here they are shown infesting maidenhair fern Volck, a miscible oil spray, may be used effectively as a dip in con- trolling most scale insects. This material should be available from local plant supply stores or from reputable seedsmen. DDT has proved an excellent material for killing scale, and is safe on most plants. In using Volck, or any other control measures, the treatment should be repeated several times to give a satisfactory control. Aphid or Greenfly Although aphids are the commonest of all house-plant insects, they are by far the easiest to control. Aphids are small, usually green in col- or, and capable of multiplying rapidly. If left alone they will do much damage. Usually they are wingless, but under adverse conditions, such as in late fall, they produce winged stages. Aphids may come into the home on cut flowers or potted Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original New Hampshire Agricultural Experiment Station.
