 twenty trees in three orchards of 8(i<l ti-e<'s were fnnnd infested. It is not <inite 

 elear hiiw tliis infestation was started. Imt it is believed that the cocoons were 

 introduced on sonii' iiarjun^'-eases contain'ins; nursery stocli from Oregon, V.S.A. 

 Close attention was paid to eoidrollini; tliis outhrealc. and the methods employed 

 are described liy :Mr. ( 'niniini;lutin in tlie I'roeeedin^'s of the British Coliimliia Euto- 

 molo,gical Society. -\'o. -J. T.I12. jiaue lis. lOviilently success attended the efforts of 

 the Provincial authorities, because no ■'worms" were found at .Vrmslrong the 

 following season of I'.li:!. and none have been found since (IIH."). 



In litlo. however, another outbreak occurred in the City of Kelowna. introduced 

 through the medium of infected cai's. In the spring of V.il."i tills infestation still 

 required attention, but the number of larvip taken was \ ery few (eiglit). 



During this past summer. l!n."i. we nnfortunatel,\- have to re]»irt two of the 

 most serious outbreaks that have as yet aiipeared in the I'rovince. one at Westbank 

 and the other at Okanagan Landing. The first was reporte<l in August and the latter 

 did not become ajiparent until late September, when nian.v larv:e were entering 

 hibernation. It is not possible at this time to give any further information on these 

 two outbreaks, as they occurred during the jiast seasini. lint enough has been shown 

 to inilicale that the status of the codling-moth in I'.ritish CoUunbia is assuming .-ilarm- 

 ing proiiortions. In the Aiuiual Iteport of the ()nlario Entomological Society. I'.ili;. 

 I drew attention to the fact that in l'.t12 the ULotb was freciuenting orchards in 

 Washington State about thirt.v unles south of the Ilritisli Columbia boundary-line. 

 I have not received an.v later information that it bad .-ipiiroacbed closer than thirt.v 

 miles, but we camiot avoid the fact that with the inform.ition given in this article 

 we nuist regard the co<Hing-moth as an orch.ird pest that we will soon be called u|ion 

 to fight. 



A third occurrence of some l.-irva' in the fruit of apples growing at Eburne. B.C., 

 near Vancouver, was discovered in September of the past summer (l!)l."pt. but at 

 present there is uo more information offering on this outbreak. It is believed, also, 

 that another centre of infestation occnrre<l at Kelown.i duiiug the jiast year. 



You will, no doubt, be jileased to bear tlial 1 ir. C. Cord.m Hewitt. Dominimi 

 Entoiuologist, has arranged for the prelindnary studies into the life-history of this 

 moth under conditions that pertain to the (ikaii.igan \'alley. .\ commenceiueut of 

 this stud.v will be begun during the connug se.asim (IPKil with the main ob.iect in 

 view to advise the fruit-growers more intelligently on local methods of control.

For the jairpose of iilacing before the frnil-growc^rs of r.rilish ('oluuil ia. more 

 liarticularly those residing in the Okauagan. a few notes on the control of the codling- 

 moth, in .'inticipation of this insect assuming iiLijiortance as a pest in the I'rovince. 

 it has been thought advisable to mention a few important considerations bearing on 

 its life-histor.v and methods of control. 



We have not had any oii|i(u-tunity. as \et. to make a searching inciuiry into the 

 life-hist(a-y. the number of broods, or the relation of the movements of the lavv;e 

 to the development of the apple un<ler conditions th.al lu'evail in the okanagan 

 V.-illey. .\-s has already lieeii stated, several small o\itbreaks have ..ccurred from 

 time to time .-it one or two points, but the etfoi-ls of thi' lns|iectors have been directed 

 maiidy towards extermination of the insect rather than to any serious attempt to 

 determine the important points in the life-history of the moth, which would naturally 

 govern the effectual methods of control. It is n<it sujiposed that the habits of the 

 moth will vary very luueh fvom it.s habits in the States of \V:ishington and Ore.gon. 

 in districts of .similar climatic influences; eonsecinently. until we have experimental
