caterpilliU'S are dark blue, with oval spots in median on all but first tew segments. 

 Over tbe whole of the caterpillars are numerous, fine, yellowish or cream-coloured 

 hairs." 



Insects of this species attack all orchard trees in the Lower Fraser with the 

 exception of the pear, which apparently appears immune. The nature of the injury 

 from these caterpillars is so well known that further reference is unnecessary. 

 Suffice it to say that spraying with arsenate of lead in the early summer and the 

 mechanical destruction of the larvre are recommended in years of prevalence. 



The Apple Fkuit-mineb {Argyresthia conjugcUa, Z. ). 



In 1S9S Dr. Fletcher, the late Dominion Botanist and Entomologist, referred to 

 this insect as one of the worst enemies of the apple-grower in British Columbia. 

 Of recent years its presence has not been noted. 



The Plum-cukculio (Conotracltelus nenuphar, Hbst.). 



It has been considered advisable to mention the characteristics of this insect. 

 Tlie adult is a thick-set snout-beetle about i/4 inch long, and it lays its eggs in 

 peculiar but characteristic crescent-shaped punctures on the skin of many orchard 

 fruits, particularly the apple, peach, and plum. 



The female weevil first removes a portion of the skin of the fruit with her 

 snout and in the cavity thus formed deposits an egg. She then, by instinct, cuts 

 Ijortions of the skin of the fruit in either direction from the point of oviposition, 

 so that as the fruit swells and grows the pressure will not crush the eggs, the 

 expansion being alleviated around the egg by the two latter formed incisions. Thus 

 a characteristic crescent-shaped puncture is produced. These shaped punctures have 

 been observed on some apple-trees for a long time neglected, growing at Agassiz 

 this summer. Furthei-more, verbal reports of the same have been received from 

 Salmon Arm. No eggs, larvre, or adults have been taken, but as this insect is 

 regarded as one of the worst affecting the fruit orchardist in other portions of 

 Canada, it is well that a sharp look-out be kept in British Columbia. 



The Cheeky Fruit-fly (Rhagoletis cingulata, Loew). 



" This imported insect was recorded by Dr. Fletcher in lOOG. lie received it 

 from Mr. W. R. Palmer, Victoria, B.C., where it was injuring some cherries. This 

 was its first recorded appearance in Canada, and Mr. Palmer stated that he first 

 noticed the holes in cherries in 1004."* 



No further records appear to have been received during recent years regarding 

 this insect and it is hoped it will not appear again. The adult is a fly and it lays 

 its eggs just beneath the skin of the cherry during the summer. Maggots about one 

 quarter inch long may be found in the flesh producing a rot of the fruit. 



The Woolly' Apple- aphis (Schlsoneura lanigera, Hausm.). 



This aphis is probably the commonest-known insect of its class to the fruit- 

 grower in the Fraser Valley. Its conspicuous white flocculent clusters in cracks and 

 crevices of limbs and in ijruning scars at once indicate its presence. Root-forms 

 also occur, forming swellings and scars on the finer roots of the trees, but as these 

 forms are hidden from view their importance is lost sight of. The secondary injury 

 caused, allowing fungous disease access to the tree, is as important as the attack on 

 the tree by the aphis itself. 



During the winter, on the stems will be found masses of the dead bodies of the 

 summer's generations, but underneath, protected from the eft"ects of temperature, 

 may be found several small aphides of a brown colour. If these survive the winter, 

 as many probably do, in the milder parts of this Province, they commence to migrate 

 to the hew wood of the past summer, when the buds begin to open." Tliey begin to
