thus many were lost; furthermore, I have no doubt also that a percentage of the 

 brood did not move at all, but remained on the same ti-ees as they were on during 

 the summer. IIoAvever. the migration as a whole was most marked, as I observed 

 before. 



Two apple-trees were so covered with aphides in September that in appearance 

 tliey resembled snow. These trees were sprayed with Black Leaf 40 and whale-oil 

 soap. This spray was veiy effective, as no aphides were found to survive. 



The Pe.\k-i.eaf Blister-mite (Eriopycs jtyri). 



This insect, which I have found in some orchards at Mission, had destroyed all 

 the fruit. It Is not necessary to mention the damage to the foliage, as this injury 

 is well known. The former observation is. of course, the most important. A little 

 infection occurs In ever.v orchard visited iu the valley, which indicates that it is 

 spread throughout the whole valle.v. - 



The Bud-moth (Tmetocera occUana). 



This insect is steadily increasing in the valley. Some orchardists believe it 

 thins out the fruit on the tree ; consequently they believe it a benefit rather than a 

 detriment. The fallacy of this view I need not expose. While spraying the past 

 season I found it working on the opening buds and blossoms the first week in April. 

 1 applied arsenate of lead, 2 lb. to T^0 gallons water, with good results, thougli 

 further demonstration spraying with this insect would prove beneficial. Its dis- 

 tribution is general, and it is probably the most serious of our pests. 



The Oystek-shell Sc.u.e {Lepidosaplics vlmi). 



This insect requires little comment pertaining to its life-history, only as regards 

 spraying during hatching season. At different points from Haney to Mission I 

 found this scale hatching, and in some cases set b.v May 15th ; while iu 1912 it was 

 about the first of June before similar conditions were noticed. This indicates a 

 wide range, due to local climatic conditions. 

 The Tent-cateepillar (Malacosoma erosa). 



These insects were hatched and well developed and doing considerable damage 

 at Haney on May 20th, having almost entirely disappeared at Mission by June 12th. 



The Oblique Banded Leaf-roller (Atchips rosaceana) . 



This insect was very numerous in this city as well as nn the Lower Fraser 

 Valley this past summer. I am convinced that this insect can be easily controlled 

 liy the use of arsenate of lead applied about May 15th, judging from this season's 

 observations. 



The Rosy Aphis (Apliis sorhi). 



This aphis is laroving to be a pest of marked importance and is spread over a 

 large territory. It works on the opening foliage and is more difficult to control than 

 other aphides, as it curls the leaf quicker than other species. In an orchard near 

 Mission there was considerable damage caused by this insect during the two 

 previous seasons. The aphis as a rule disappears to a large extent by the middle 

 of June, and reoccurs on apple-trees in September. I believe this is about the time 

 of their migration, but the secondaiT Ijost as yet has not been learned. I have used 

 Black Leaf 40, 1-SOO, on this aphis quite successfull.v, the essential point being 

 earlines.s. 



The Lesser Apple-worm (Enarmonia prunivora) . 



It is indeed reasonalile that this insect should demand its share of investigation. 

 It existed in orchards where it had not been found lief ore this summer. There 

 are three or more distinct broods closely interwoven with one another, and quite 

 frequently two larvre of different broods were noticeable in an apple, one at each 

 end. The first larva; appeared about the middle of July, and the last about the 

 middle of September. They were more numerous in orchards bordered by woods,
