804 EXPERIMENT STATION RECORD. 



Cdiiceining- the rose cliafer little is said fiirtlior than to advise the 

 planting' of decoy plants near the vineyard. He adds that the numbers 

 of the insect may be restricted by limiting their feeding areas, such as 

 sandy meadow lauds. These should be planted with annual crops. 



Since the use of poisons in the case of the berry moth is dangerous 

 it is advisable to destroy all infested fruit. 



The shade tree problem in the United States, L. O. Howard 

 ( U. 8. Dept. Agr. Yearhool- 1895, pp. 301-384, figs. 11).— In the first 

 portion of this paper the bagworm {Thyridoptery.iC ephemenvformiH), the 

 imported elm leaf beetle {Galerucella luteola), the white marked tus- 

 sock moth [Orgyia leucostignm), and the fall web worm {Hyphantria 

 cnnea), are discussed. Although a few other insects do more or less 

 damage, the author considers these the most injurious of the eastern 

 shade-tree insects. To the imported elm leaf beetle and the while 

 marked tussock moth considerable space is given, the history, distribu- 

 tion, and remedies against the insects being discussed. Some details 

 relative to the external anatomy of the larva; of the tussock moth are 

 described. 



As remedies against the imported elm leaf beetle, spraying with an 

 arsenical solution is thought the best, and in fact the only thorough 

 safeguard. The size of the tree need form no obstacle, for recent experi- 

 ments have demonstrated that spraying is applicable even to the 

 largest. The only other remedy worth noting is the destruction ot the 

 larva? in the ground before their pupation, by spraying or other means. 

 In spraying care should be taken that the ground beneath the entire 

 limb-spread and the lower crotches of large trees are reached. Some- 

 times it may be advantageous to remove the rough bark from the tree- 

 trunk. 



As regards the tussock moth, 2 classes of remedies may be employed 

 to advantage: (L) Either the eggs maybe gathered in winter or de- 

 stroyed by the use of a mixture of turpentine and creosote applied to 

 the egg clusters with a sponge at the end of a pole; or (2) the larva 

 may be attacked in their season by spraying and by the use of bands 

 of raw cotton or of insect lime. The last measure is especially good 

 for this species, since it is the only one of the shade tree insects in 

 which the female is wingless, thus rendering it necessary for the insect 

 to spread from tree to tree by the migration of its larva?. 



The fall webworm, which, according to the records of the Division 

 of Entomology, is known to feed upon 120 shade and ornamental trees, 

 may be disposed of by pruning, by burning the webs at nightfall, and, 

 in the case of city trees, by the application of arsenical sprays. Col- 

 lecting the egg masses in winter along with those of the white marked 

 tussock moth is also recommended. 



In the second portion of the work the author treats the question as 

 to what can be efficiently and economically done by city governments 

 or in their failure to act, by citizens wlio ai e interested in the i)reserva- 

 tion of shade trees do. He contends that if tlie planting of shade trees
