Description

Excerpt from Insects Affecting Greenhouse Plants Every grower of plants under glass has, at some time or other, experienced losses owing to the presence of destructive insects. Roses, Chrysanthemums, carnations, primroses, ferns, snapdrag'ons, cucumbers, lettuce, and many other plants, are every year attacked by various kinds. Of leaf-eating, sucking or other insects, resulting in losses which amount, annually, to many thousands of dollars. Much of this loss may be prevented if growers. Will adopt the remedies which are recommended in this bulletin. When a plant is attacked, the grower should Observe how the insect feeds, as such fact will help materially in deciding upon the proper remedy to apply. Injurious insects may be divided, roughly, into two classes, by the nature of their mouth parts, namely, (1) biting insects which bite and chew their food, such as caterpillars, and (2) sucking insects which suck up their food by means of their beaks, such as the aphids, the true bugs, the scale insects, etc. If the insect is a biting one, a stomach poison, such as lea-d arsenate, is usually applicable, but if the species is a sucking one, such poisons would be useless because the insect would insert its. Beak through the poison and reach a safe feeding place beneath. Sucking insects, therefore, contact insecticides are recommended, such for instance as preparations containing nicotine. Certain insects. Such as. Aphids and white fly are best controlled by fumiga tion with a tobacco preparation or hydrocyanic acid gas. Boring or root destroy ing insects require a different treatment. In this bulletin information is included which should assist the grower to recognize the various kinds of insect pests with which his plants may become infested. The remedies for the insects discussed have bee-n found of value and if the grower will follow these carefully, he will undoubtedly keep the pests under control and thereby protect his plants. In addition to insects destructive in greenhouses, chapters are also included on animal pests, other than insect-s, and on useful or beneficial insects.
