suggested the use of boiled linseed-oil, and burning it until it became sticlcy like 

 tanglefoot. Aloes and carbolic acid were added to ttie mixture and tlie whole applied 

 to the trees. It proved, I believe, au effective remedy. 



Mr. Lyne: I might say that there are numerous washes in operation. Crude 

 coal-tar has been proved effective. 



Mr. Tom Wilson: I have tried coal-tar on sapling ash against rabbits; so far 

 as I know, no harm resulted. We used to band holly-trees for half a foot. 



Mr. Brittain : Asphaltum is being used largely now. It expands and contracts 

 with the temperature and it is permanent. 



Mr. Lyne: This has been experimented with, and I believe that, on occasion, 

 injury resulted. 



Mr. Kennedy: I never saw asphaltum used in the Santa Clara Valley, California. 



Mr. Lyne : They used whale-oil also. 



Mr. Brittain : They also use carbolic and limewash ; with a system of " worm- 

 ing " the wash allows one to see the borings better. 



Mr. Boncquet: When are the eggs laid? 



Mr. Lyne : In July and early August. 



Mr. Edwin Smith: Have you any notes on the eggs of AnarsUi Uneatclla in 

 fruit and the effect of cold-storage on them? 



Mr. Lyne : Refrigerated peaches will come in and they will be pronounced fairly 

 clean. If many crates come in at one time, the merchants unload at their own time. 

 By holding the fruit thus many worms will hatch out. 



The Chairman: We will now proceed to the next paper. 



CUTWORMS AND THEIR CONTROL. 



By M. S. Middleton, Distkict Horticulttjkist, Nelson, B.C. 



The cutworms in the Kootenay and other Interior points did practically no injury 

 this year (1913) to crops. This is attributed to the larvie having been parasitized 

 last fall. It was almost impossible to find a cutworm this year, where last year they 

 could be found in millions. It seems to be the history of all insect ijests taken over 

 a number of years that it is one of epidemics alternating with periods of comparative 

 immunity, which is brought about almost wholly by parasitic attacks. These para- 

 sitic controls are of the greatest advantage iu keeping down the ravages of all insect 

 pests, and for this rea.son the study of the new entomology is not only interesting, 

 but, I believe, quite practical at least in many cases. These periodical outbreaks are 

 always liable to appear, however, and we should always be prepared to combat them 

 to the best advantage. We find that the cutworms were extremely bad during the_ 

 seasons of the years 1900, 1906, and in 1912. They gradually worked up to this 

 epidemic stage and in the year following were extremely scarce. 



Although we are able to control the outbreaks of cutworms quite satisfactorily, 

 there still remains a great field for further investigation and experimentation work. 

 It was my intention to have carried on a number of experiments this summer, with 

 the object in view of finding out, if possible, more effective means of controlling these 

 pests, but owing to the immunity this year was unable to do so. We must all feel 

 pleased that the cutworms were scarce and the cause of very little loss this year. 

 I shall have to confine my remarks to the results I obtained last year while dealing 

 with possibly the greatest scourge of cutworms which the Kootenay District has had 

 since the advent of agriculture. The worms were so thick that the ground could 

 be actually seen moving with them, and they could be heard feeding on the clover. 

 In parts the clover-crops were completely devoured by the cutworms. Various con- 

 trols of poisoned baits were used with varying results. 



I found them doing injury to nearly every cultivated plant, including green 

 grain. The greatest los.ses were caused in the vegetable-gardens and in youug 

 orchards, where the worms of the climbing species would crawl up the small trees 

 and eat out the upper buds. This did not result in the killing of the trees, but the
