branches, stems, or roots. The Cherry Borer (Maroga gigcintella) is. 

 another troublesome insect to Peach trees. Remedies : The most 

 effective way of dealing with these pests when above ground or just 

 below the surface is hand picking as soon as the insects are discovered. 

 2. Syringing the affected stems or branches with a strong kerosene 

 emulsion, or hot water after scraping off the loose bark. 3. When the 

 insects attack the roots, holes should be made with a crowbar, and into 

 each one place a small quantity of bi-sulphide of carbon. For full 

 particulars respecting this remedy see page 98, volume 1. 



Caterpillars. Various kinds of these insects attack the foliage, and 

 more especially early in the season. They also feed upon the flowers, 

 and to some extent upon" the young fruit. Remedies : 1 . Powdered 

 Lime. 2. Hellebore Powder dusted over the trees frequently. ij, 

 London Purple or Paris Green, in solution, used as a spray. 4. Tobacco 

 Water. Full information as to the preparation of these remedies will be 

 found on pages 100 to 102, volume 1. 



Red Spider. This minute insect often affects Peach and Nectarine 

 trees, and more especially during protracted dry weather. It increases- 

 with great rapidity and causes serious injury by feeding upon the juices 

 of the leaves. For remedies and full description of the insect see page 

 82, volume 1. 



Scale. Various species of Scale insects more or less injuriously affect 

 Peach trees, and more especially when they are unhealthy or lacking 

 vigour from the effects of dry weather, poverty of the soil, the want of 

 drainage, or other causes. One of the most common and troublesome 

 species is the one kr.own as Brown Scale (Lecanium hemisphcerictim), 

 which is very widely distributed. Piemedies : I . Kerosene Emulsion. 

 2. Resin Compound. 3. Soap and Water applied hot. For particulars 

 as to these remedies see article upon Insecticides, page 98, volume 1. 



Tliread Worms. Peach trees sometimes suffer from the attacks of a^ 

 minute insect commonly known as the Tliread Worm, also as the Gall 

 Worm and Nematode Worm. The .scientific name of the insect is 

 Tyhnchus arenarius. These insects bury themselves in the roots and 

 form swellings, or galls as they are commonly called. They increase with 

 great rapidity, and when a tree is attacked by them, are always found in 

 large numbers. When trees are attacked by these pests there is very 

 little chance of their being cured, as the soil becomes infested with them. 

 For a full and complete description of these insects see article upon Root 

 Galls, page 95, volume 1 . 



Thrips. These troublesome minute insects often seriously affect Peach 

 trees, and more especially after mid-season and prolonged dry weather. 

 They are found chiefly upon the under sides of the leaves, to which they 

 are very injurious, as they feed upon the juices. For remedies and 

 description see article upon Thrips, page 85, volume 1.
