REPORT FROM THE OKANAGAN DISTRICT: INSECT PESTS OF THE 

 YEAR IN THE OKANAGAN. 



Bv W. H. Brtttain, Provincial Entomologist for Xova Scotia (formerly of 

 British Columbia). 



The summer, of 1913 was not marked by any insect outbreaks of unusual severity. 

 Host of the usual pests were present in greater or less numbers, while several 

 interesting records were made for the first time. The following are some of the 

 most important jjests to receive attention during the year : — 



BUD-WOR.M {Tmctocera ocelJatw). 



This insect was found working in several orchards in the Kelowna District, 

 though not in sufficient numbers to do a great deal of damage. Three distinct 

 species of moths were reared from larvae resembling those of the true bud-moth 

 {Tinetoccra oceU(i)ia). This is interesting in view of the fact that the twig-boring 

 habits of the bud-moth, which have been repeatedly observed in British Columbia, 

 do not appear to have been noted elsewhere. It is possible that one of these other 

 species is responsible for this work. 



The Antique Tussock-moth (Orgyia antiqtia). 



The larvfe of this insect were unusually numerous in the orchards this season. 

 l>ut it is of only minor importance as a fruit pest. 



Climbing Cutworms (Noctuidse). 



These insects, of which we had nearly a plague last year, could hardly be found 

 at all this season. As we had no facilities for rearing these insects last season and 

 they occurred in such small numbers in the spring of the present year, we do not 

 know of what particular species they belonged. 



Tent-caterpillars {Malaeosonia .s;//). ). 



These insects appeared in large numbers in the spring, but were practically 

 wiped out before reaching maturity by their parasites and b.v a bacterial disease 

 with which they were attacked. From the large number of larviie we collected for 

 rearing no adult moths emerged. 



Codling-moth {Cudia pomoncVa). 



There was no further outbreak of this insect in the Armstrong District this year, 

 the measures taken for its eradication having apparently proved successful. An out- 

 break occurred at Kelowna, however, though not in the same orchards as last .vear. 



IvESSEK Apple-worm {Enarmonia prunivora). 



This insect was unusually abundant throughout the orchards of the Okanagan 

 this season, and many specimens reached the office from the different districts. Prom 

 the letters that we have received, it would seem that this insect is on the increase. 

 From its general resemblance in habits, life-history, and appearance to the codling- 

 moth, it is frequently mistaken for this more serious pest.
