material referred to on pages 16 and 17. Orchard infestations can be

 In making this statement it is assumed that the orchard is being 

 eared for by up-to-date methods for protection from the codling

instances it probably would be advisable to use bands and to discon- 

 tinue spraying, especially in cases where the infestation is light or 

 moderate. If the infestation is bad, creosoting, banding, and spray- 

 ing all should be used in their season, in order that the insect may 

 be brought under control and the numbers present reduced 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 bast 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 bein? made.
