20 THE REPORT OF THE No l» 



Division No. 5 — London District By J. A. Balkwill. 



In this district I have not heard of any serious damage from insects that fre((uently appear 

 in large numbers, but we have had the different species of Aph's in great quantities early in the 

 season on very many kinds of shrubs, causing a considerable injury later on ; there was a very 

 perce]itible decrease in their number, I have no doubt owing to the destruction of them by the 

 larvpe of the Ladybirds which were <ibserved on many of the plants infested. 



The Potato Beetle (Doryphora decemlineata) appeared in large numbers as soon as their 

 food ]>lHnt a{>{ieared above ground and caused some damage, but it was generally remarked 

 that in a >hoYt time their numbers had become very much decreased from what cause I cannot 

 say, as their destruction by the usual methods of applying Paris Green was not more commonly 

 done than usual. 



The Cottony Maple Scale has again appeared in numbers sufficient to cause anxiety among 

 the loveis of our beantiful maple trees, but we are in hopts that its natural enemies will 

 keep it in check as in former visitations. 



The Asparagus Beetle (Orioceris IS-pundata) Appeared i^ increasi d numbers in the noithern 

 part of the City of London, but has not spread as much as we were told to expect [ have 

 searched for.it in the southern part nnd could not find one beetle on several beds visitt d. 



Complaint was made in one or two cases of tomato plants being bored by some grubs and 

 on examination I found the larva of what I believe to be llyJra'cia cataphracta. Only one of 

 the larva was secured and that died before it reached the pup>l stage ; this is the first time I hat 

 this has been observed in our neiuhbnrhood, so far as we have any record. 



Very few peas were gtown in this vicinity and were generally sown late so that it is too 

 early for a full repoit cm this crop. In Oxford County [ have heard that the crop is ladly 

 infested. W( uld not this be a favourable time to treat all the peas, as the quantity is snial! 

 and the expense would not be a serious item ? 



Very few of the apples in this part of the district are damaged by the Codling moth. The 

 cool wea' her just after the fruit had set would probably account for a diminution in their 

 number 1 he plums also have not bt en so much injured by the Curculio, and although bitten 

 by the insect no larva could be found inside a consideiable quantity examined from trtes where 

 no .' praying was done. 



Tho Cigar Case-bearer (Coleophara Fhtcherella) were very numerous oa the leaves ot the 

 apple, but the insect being so snvili the injury was not perceptible. 



The presence of the Eye-spotted Bud-moth ( Tmetocera) coidd be plainly seen in the orchards 

 by the leaves at the ends of tho twigs being dead and drawn t' geth'-r by the web of the insect. 



No injury from the Dry Clover-moth (Asupia coslalis) was found in the barns where it was 

 so abunHant the winter before. 



■n the discussion which followed the reading of the Directors' reports,Prof. Lochhead stated 

 tfiat the )2-spolted Aspaiagus beetle was very prevalent through the Niagara Peninsula and 

 was travelling gradually westward and northward ; at Guelph it was already very abundant. 

 The other species (Criocer s aspanii) was causing much damage ti> the plants in St. Catharines 

 and Hamilton but was not spreaiUng over the country to the same extent. Both kinds will 

 require to be wa'ched and promjjtly treated wherever they establish themselves. Dr. Howard 

 said that it would be interesting to ascertain whether the Aspira^ius beetles spread beyond the 

 Upper Austral Belt, the boundary of which extends from Niagara t rough Hamilton and London 

 to Detroit — Prof. Louhhuad in reply said that they ha I not boen found further nort'i than 

 Guelph which is in the Transition Zone just beyond the Upper Austral. 



With regard to Cut worms, referred to by Mr. Young, Dr. Bethune stated that they 

 appear to have been very abund.int ad over the country during the past season. He had 

 receivtd a communication fr< m Mr. Boulter, of Tryon, Prince E.lward Island, who complained
