 Pest in New Jersey. — Canadian Entomologist, London, Ont. xlix, 

 no. 2, February 1917, pp. 73-75. 



The Psyllid, Trioza alacris, bas only recently become sufficiently 

 numerous in New Jersey to disfigure its host, Laurus nobilis, at all 

 seriously. It has probably been introduced from Belgium on imported 

 stock and may occur in other parts of the country. Its presence can 

 easily be detected by the curled, discoloured leaves, usually at the 

 tips of the branches, containing what appear to be cottony masses. 

 For control measures, when the infestation is slight or the number of 

 affected trees is small, the infested leaves may be picked off and 

 destroyed. In more severe cases a spray composed of 8 oz. Black Leaf 

 40 with 8 lb. whale-oil soap in 100 gals. [?U.S.] of water has been used with 

 fair success in New Jersey. Fumigation with hydrocyanic acid gas 

 (the American 1-1-3 formula being used) has also been reported as 

 successful.

 for demonstrating the Control of Injurious Insects. — Jl. Econ. 

 Entom., Concord, N.H., x, no. 1, February 1917, pp. 20-25. 



The authors strongly advocate the holding of local demonstrations 

 for the dissemination of knowledge relating to insect pests. By this 

 means the farmers can be convinced of the practicability and profit 

 of the practices recommended, and demonstrations can be conducted 

 in any community where conditions render them desirable. The 

 subjects for such demonstrations should be chosen and conducted 

 in such a way as to help the grower to fight the insect enemies of his 

 crops in a practical manner and under the conditions actually existing 

 on his farm. The problems to be solved are problems of applied 

 entomology and can only be worked out by expert entomologists, 

 upon whom rests the responsibility of initiating and guiding this 

 work along entomological lines.
