Reports to the Board of A griculture. 179 
stage of the Harvest Bug ( Leptus 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 larvae it must be done by 
some other creature than the Acarus referred to here. 
Insects in Raspberry Buds.— The larva? of the Raspberry Moth 
( Lampronia rubielld) 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 Pear 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 numbers of Beetle Mites ( Oribatidse ). 
As mentioned in previous reports, these Acari do no harm. Albert 
Michael endorses this statement. Oribcdidse are extremely abundant. 
Trees may be seen covered with them on which the bark is 
unharmed. 
Tiees may fiequently be seen showing the diseased appearance 
presented by the sample sent which have no Oribatidse or any mites 
01 insects upon them. Certain trees under observation never have 
had any arthropod pests lor 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 : — 
Theie 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. 
II the grease is good it lasts a long time. 
. The best 1 know is that sold by Messrs. W. Horne & 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 
v heie 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
