These are the more important pests observecl or reported generally, except the 

 grasshoppers, which are certainly plentiful enough to be taken notice of. Mr. Ben 

 Hoy reports on the 14th that he visited a small orchard surrounded with range land 

 practically defoliated by grasshoppers (species not identified) in Kelowua. I will 

 now take the insects observed or reported locally. 



A Plusia. il'lusia caVfornica). 



From Larkin, Veruon, Kelowna, Summerlaud, and probably Arnistrong. My 

 attention was first attracted to the larvte of this Plusia in Kelowna on June 2nd. 

 where I found it doing a great deal of damage in a market-garden, lettuce-plants 

 being particularly attacked and completely ruined. Although general in Kelowna. I 

 did not find any other places seriously infested, neither did I receive any later reports 

 to this effect. My attention was next called to it on June 10th in Larkiu, where a 

 100-aere field of alfalfa had just been cut, and millions of the larva? were migrating 

 to an adjoining alfalfa-field, and in transit cleaning up the home vegetable-garden ; 

 sweet corn being immune from their attaclc, potatoes nearly so, lettuce and peas 

 being i^referred, onions being also attacked, and large numbers were climbiug on the 

 walls of the house. The attack on the home garden seemed to be the cause of 

 attention being first drawn to them. The same day I was called to an orchard in 

 ^'ernon where alfalfa and clover was growing between the tree-rows ; here they were 

 also present in great numbers, particularly on the alfalfa, and considerable luimbers 

 were on the fruit-ti'ees, attacking both foliage and fruit and doing considerable 

 damage. The larvm appeared to be coming from the weeds in an adjoining orchard 

 which was in a state of neglect. I collected in all 200 larvse in various stages of 

 growth and placed them in breeding-cages ; a few commenced to pupate on June 12th. 

 A disease attacked the larvie and large numbers were also parasitized, with the 

 result that onl.v eleven larvte reached the pupal stage; the rest succumbed to the 

 disease or i)arasites. Out of the eleven puiuB only four adults emerged ; from the 

 other seven pupje Tachinid flies emerged ; in the case of inxpce of larva? taken in , 

 Kelowna, Braconids emerged. Of those pupa? i)arasitized by Tachinids only one 

 parasite emerged from each pupa, whilst in the case of ijarasitized larva; which did 

 uot reach the pupal stage two Tachinids emerged from each. Out of the 200 larva; 

 taken only 2 per cent, reached the adult stage, and apparently the results were some- 

 what similar in the field, as a second brood of larva; was uot noticeable and only 

 very few adults were observed. A specimen also reached mo from Pummerland, but 

 nothing serious reported from there. A report of a serious invasion of the army- 

 worm reached me from Armstrong, but did not get the opportunity to investigate, 

 neither did I receive any specimens from there, but from the descriptions I received 

 of the larvju I am led to believe that it was the same Plusia as I observed in Larkin. 

 Vernon, and Kelowna. 



The CoDLi>'G-MoTn (Carpocapsa (Cijdia) ponwiirlla). 



An incipient local infection in Kelowna. Mr. Cunningham with his usual 

 thorough methods, will probably have it exterminated bj- next season. 



An ArPLE-SAWFLY {Taxonus nigrosomia) . 



I first observed larviB of this sawfly in September, 11>12, in Armstrong, and 

 Mr. W. H. Brittaiu found them about the same time in Vernon. The full-fed larva- 

 apparently come from the bush adjoining the orchard, evidently for the purpose of 

 finding a place to hyberuate in, and had selected an Ontario and a Wagener tree 

 for the purpose. Every apple on the Ontario tree had either one or two larv.ie; the 

 Wagener apples only had a few ; a hole was eaten into the fruit slightly deeper than 

 the length of the larva, after which the larva either remained quiescent or left the 

 fruit for more comfortable quarters. Mr. Brittaiu bred some of the larvte and had 

 them named.
