TwE civ-THiRD Report on Observations of Injurious Insects and 

 Common Farm Pests During 1899. — By Eleanor A. Ormerod, 

 LL.D., F. R. Met. Soc, etc. 



Miss Ormerod's last Report, which is the first of a new series, has 

 just come to hand. As usual, it is full of interest to the entomologist, 

 and contains many valuable practical suggestions for the farmer and 

 fruit-grower. 



There were, during 1899, complaints of the depredations of the 

 ordinary farm and orchard pests, and also of a few which had been little 

 noticed previously. The value of Dr. Ormerod's Reports to Canadian 

 readers is shown by the large number of injurious insects treated of, 

 which are now common to both Europe and America, or are represented 

 on one continent by species closely allied to kinds with similar habits 

 found on the other. 



Cabbage butterflies of three species were very prevalent and 

 destructive. Dusting the plants with a mixture of lime and soot was 

 found to be of no avail, while syringing them with Little's "Antipest" 

 was satisfactory. There is no mention of the simple and very effective 

 remedy of dusting the plants with insect powder and flour, which has 

 been found by far the best remedy in this country. An account is given 

 of good work in lessening injury by collecting the butterflies. This was 

 by the boys at Mr. W. Bailey's Aldersey Grammar School, in Cheshire. 

 In the previous year the boys turned their attention to the caterpillars, 

 and from 240 plants they gathered more than 5,000 caterpillars. 



The Cheese and Bacon Fly. — This is the parent of the well-known 

 " skippers " in cheese. These larvae are also frequently found injuring 

 hams. The remedies proposed are all of a preventive nature, such as the 

 close screening of windows in bam and cheese curing rooms to keep the 

 flies from entering, the frequent rubbing and turning of cheeses during 

 the egg-laying season, and the destruction of the flies in the curing 

 rooms by means of pyrethrum insect powder or the ordinary fly paper. 

 All cracks in cheese should be filled at once with a mixture of flour, 

 butter and pepper. 



Portions of cheese or ham that are found to be attacked, should be 

 cut out as soon as possible after observation ; and, with regard to cheese, 

 it is recommended that after cutting out the piece, a thorough dusting of
