drive away an insect so utterly depraved in taste as to relish the wild,, 

 bitter crab apple is a question. As remarked in regard to the use of 

 "poisonous compounds to kill the plum curculio, which is now recom- 

 mended for the codling moth and has been indorsed by some of our 

 leading fruit growers and even entomologists, there seems to be no 

 reason to suppose that this remedy would be any less eflfectual with 

 the apple curculio than with the others mentioned. It may be possible 

 to furnish the beetles with inviting shelter, near at hand, for winter 

 quarters and then to destroy home and occupant. Those afflicted with 

 this and other pests should carefully observe their habits and try all 

 possible, practical means to effect their destruction. 



INSECTS AND REMEDIES. 



INSECTICIDES. 



The following are the insecticides enumerated by Prof. Riley, in- 

 the catalogue of the exhibit of Economic Entomology, at the New Or- 

 leans Exposition: Arsenical mixtures, namely, London purple and 

 Paris green — two cautions to be avoided — inhaling the dust, and pur- 

 chasing the adulterated Paris green, which may be known by its color ; 

 bisulphide of carbon, for underground work, and stored grain ; borax, 

 for roaches ; camphor, for dry goods ; carbolic acid, one part in a hun- 

 dred of water ; hellebore, one part in twenty of flour, or four ounces in 

 a gallon of hot water, and sprayed on currant bushes; petroleum, milk 

 or soap emulsion ; pyrethrum, blown on dry, or sprayed, one table- 

 spoonful to one gallon of water; soap-suds, for aphides, and all soft- 

 bodied insects; tobacco decoction, for insects on plants. 



Pyrethrum may be applied by mixing with water, or as a powder.. 

 In the latter case it still remains effective when considerably diluted 

 with flour— a fact not neglected by unprincipled vendors. The liquid 

 mixture— a tablespoonful to two gallons of water— may be sprayed on 

 to plants, or in stables and poultry houses, or may be rubbed directly on 

 to animals being pestered by lice or flies. The powder may be 

 dusted on to animals and plants by use of a bellows. In the same way 

 it may be used in rooms to kill flies and mosquitoes, or, if preferred, 

 as the dust is obnoxious to the neat housewife, it may be placed on 

 papers in parts of the room.
