Marlatt (C. L.). Losses caused by Imported Tree and Plant Pests.— 



American Forestry, Washivqton, D.C, xxiii, no. 278, February 

 1917, pp. 75-80, 14 figs. [Received 18th April 1917.] 



Following upon the report of the Federal Horticultural Board of 

 the U.S. Department of Agriculture, recording the detection during 

 1916 of 193 imported insect pests, inchiding 14 scale-insects, the 

 brown-tail moth [Euproctis chri/sorrhoea], egg-masses of European 

 tussock moth [Orgyia antiqua], pupae of dagger moth [Acronycta], 

 cocoons of pme sawfly [Diprion 8imile] and a potato weevil, the estab- 

 lishment of a national quarantine on plants, trees and nursery stock 

 is advocated. 



Some account is also given of the losses due to several of the more 

 serious pests, such as Anihonomus grandis (cotton boll weevil), 

 Aspidioius pemiciosvs (San Jose scale), Icerya pnrchasi, Euproctis 

 chrysorrhoea, Cydia pomoneUa, Lymantria dispar, Cydia {Laspeyresia) 

 moJesta infesting the peach, Mayetiola destructor (Hessian fly), etc.

 Washington, D.C, xxiii, no. 279, March 1917, pp. 147-153. 



This paper emphasises the necessity for greater care in protection 

 of imported stock from plant pests, and discusses the question of an 

 embargo on importations of plants from the importers' point of view. 



Boy Scouts battle Moths. — American Forestry, Washington, D.C, xxiii, 

 no. 279, March 1917, p. 165. 



In Ohio, the State has for the first time called upon the Boy Scout 

 organisation for help in the control of the tussock moth [Hemerocampa] ; 

 m a two weeks' campaign in the town of Canton, 3,000,000 eggs were 

 collected. It is suggested that this precedent may be followed by 

 other States to great advantage. 



That Tent in the Tree. — American Forestry, Washington, D.C, xxiii, 

 no. 279, March 1917, pp. 171-172, 2 figs. 



The necessity for searching out the egg-clusters of the tent cater- 

 pillar [Malacoswna^ during the winter is insisted upon. The nests 

 should be removed from the trees with a brush or by hand and the 

 larvae crushed on the ground. Nests in the higher parts of a tree 

 should be burnt out by means of a torch saturated with kerosene. 

 The wild cherry is a favourite food-plant of these caterpillars, though 

 apple, plum, peach, pear, rose and other trees may be attacked.
