stage of the Harvest Bug {Lephcs autumnalis). These mites do not 

 (as far as personal observations go) damage plants. They are 

 frequently found on soil. 



These large red mites shelter under the bark of trees. 



If any damage is being done to the apple trees otherwise than 

 that caused by the green Winter Moth larvte it must be done by 

 some other creature than the Acarus referred to here. 



Insects in Easpberuv Buds. — The larvae of the Raspberry Motli 

 {Lampronia 7'ubiella) were sent by a correspondent from Ryarsh, 

 West Mailing, where they were doing much harm in his plantations. 

 All necessary information can be found in the revised Leaflet No. 14. 



Canker Disease in Peak Trees (confused with Beetle Mites). — 

 An examination of some pear wood sent by a correspondent of the 

 Board has been made. 



There were present great nund^ers of Beetle Mites {Oribatidw). 

 As mentioned in previous I'eports, these Acari do no harm. Albert 

 Michael endorses this statement. Oribatidse are extremely abundant. 



Trees may be seen covered with them on whicli the bark is 

 unharmed. 



Trees may frequently be seen showing the diseased appearance 

 ]»resented by the sample sent which have no Oribatidse or any mites 

 or insects upon them. Certain trees under observation never have 

 had any arthropod pests for fifteen years, and yet show all the 

 symptoms present in the specimen sent which are well known to 

 anyone connected with fruit culture to be sure signs of canker. 

 This was the cause of the disease in this case. 



Grease-banding. — Information regarding grease-banding for 

 Winter Moth was sent to a correspondent, as follows : — 



There is no other substance known than cart grease for banding 

 trees. Various kinds are made and sold for this purpose and 

 probably some of these contain other substances in combination. 



If the grease is good it lasts a long time. 



The best I know is that sold by Messrs. W. Home & Son, Perry 

 Hill, Cliffe, nr. Rochester. 



[Special thick papers are now sold for this purpose, which will 

 remain on the trees more than a year. The importance of grease- 

 banding has been shown more than ever during the last year or so 

 where Winter Moth is the main pest. The plate given on page 42 

 shows an orchard so treated and the best height to band the trees. 

 The effect in this orchard has been marvellous. Previously the foliage
