GIPSY MOTH AND BROWN-TAIL MOTH AND THEIR CONTROL. 17 



will probably be necessary to creosote egg clusters in the winter and 

 vpray in the spring if the insect is to be controlled. In any case 

 thoroughness is a prime essential if good results are to be secured. 



All poor or hollow trees should be removed, and if badly infested 

 woodland is near by the orchard trees should be banded with tangle- 

 foot. Orchard infestations can be managed by following up these 

 methods, and it will not require much additional expense or a great 

 deal of extra work to protect the trees. In making this statement it 

 is assumed that the orchard is being cared for by up-to-date methods 

 in order to protect it from the codling moth and other injurious 

 insects and diseases, and it is improbable that these results can be 

 brought about in neglected orchards or where the owners do not prac- 

 tice the best horticultural methods in handling their growing trees. 



HAND METHODS FOR CONTROLLING THE GIPSY MOTH IN CITIES 



AND TOWNS. 



The same methods that are used in orchards are applicable in cities 

 and towns and for the treatment of park and shade trees. In certain 

 instances it would probably be advisable to use tanglefoot bands or 

 burlap, preferably the former, and to discontinue spraying in cases 

 where the infestation is light or moderate. If the infestation is bad, 

 creosoting, tanglefooting, and spraying should all be used in their 

 season, in order to bring the insect under control and reduce the num- 

 bers present to a minimum. 



The proper method of handling the gipsy moth in any town, city, 

 or park or on private estates, should be based on the infestation as 

 determined by some one who is familiar with gipsy-moth work, if 

 the best results are to be secured at a minimum expense. Much en- 

 ergy and money may be wasted in applying remedies unless their 

 application is based on a thorough knowledge of existing conditions. 

 An owner of an infested estate should have an examination made by 

 some qualified person who can give reliable recommendations as to 

 treatment. It should be borne in mind that conditions as to infesta- 

 tion vary from year to year, and this should be considered when 

 plans for treatment are being made. 



METHODS OF CONTROLLING THE GIPSY MOTH IN WOODLAND. 



Satisfactory control of the gipsy moth in woodland by the em- 

 ployment of hand methods such as have already been mentioned is 

 entirely impracticable unless the tree growth is particularly valued 

 for purposes other than lumber. If the woodland is situated near a 

 large city and occupies space that is likely to be utilized in a few 

 years for building lots, considerable money may be expended to ad- 

 vantage in protecting the trees, as these will make the property much
