The Bud-moth (Tinctocera occUana). 



This pest, although as j-et only reported from Keh)wna, is probably more wide- 

 spread in the valley, is of great economic importance, and care should be taken 

 that it is not allowed to become a serious pest here. 



BiD-wEKviLs (Ccrrdiicus artcmiscw and Minctus setitlosus). 



I'Veding on buds and opening leaves of apple-trees at Tenticton. 

 The Flat-headed Chebky-tree Borer (Diccrca (lirarkntd). 



Only reported from Vernon, where two specimens were tal^en by Jlr. W. II. 

 Brittain in 1912. 

 The Peach-tree Borer (Saiiiiinnidca w/fioxw). 



This pest is only reiiorted from Summerland, \\-here a considerable number of 

 trees have been killed by it; probably present to some extent in all the peach 

 districts. 

 The Peach-twig Borer (iiiarxia lineatelhi) . 



A serious pest in the southern Okanagan. and very abundant this year, probably 

 owing to neglect of thorough spraying. 



Jlr. Lyiie: To review all tlie insects mentioned by Mr. Itnhman would consume 

 several davs. I will confine my attention to those of most importance. The Pliisia 

 generally occur spasmodically owing to the extent of parasitism they are subject to 

 iir this country. Onion-thrips are very prevalent this year in Kelowna, and affected 

 fields are especially easy to notice owing to the sickly greyish discoloration of the 

 leaves and stalk of the onion. The result has been a reduction of growth. Onion- 

 ground should be ploughed in the fall, the idea being to make it a difficult matter 

 for the adults in the soil to emerge next season. Stir soil during the muter, if 

 jiossible. to let the frost act. Except for the presence of the codling-moth in this 

 locality, the peach-twig borer is very prevalent and destructive and most important. 

 I'nless spraying is done very few sound i)eaches will be found next year. We know 

 this insect as very serious. This Society is posted as to procedure, for the life- 

 history was published last year in Bulletin No. 3 of our series. Methods of com- 

 bating this pest will be found in the account. The larva; hibernate or pass the 

 winter in crotches of the tree under bark, etc. The peach-root borer is another 

 in.iurious insect of prime importance. The larva^ attack apricot and plum, as well 

 as iieach. These larva», which may be found around the root, and a mass of gum 

 will indicate their presence, and must be cut out by hand, using a curved bladed 

 knife for the purpose. An account of this insect appeared in Bulletin No. 3 of last 

 year's proceedings. Copies of this bulletin can no doubt lie obtained from the 

 .'Secretary at any time. 



THE CONTROL OF INCIPIENT INFESTATION OF CODLING-MOTH IN A 



NEW DISTRICT. 



By W. H. Lyne. Assistant Provincial Inspector of Fruit Pe.sts. 



The most practical method of dealing with a local incipient infestation of 

 codling-moth depends upon the particular season of the .vear at which the infestation 

 is discovered, and the time decided ajjon to commence o])eratious with a view to 

 its extermination. I need hardly preface my remarks by saying that it is the 

 first object of this Department to exterminate an outbreak of this moth immediately 

 on its arrival, for the Department has been brought up side by side with the growth 

 and development of the fruit-growing industry of the Province. 



So far experience has taught us that there are only two drastic melhods that 

 will give satisfactory results. One of these consists in (lcstro!ii)i(j rrrrij iiarliclr of
