lot ENTOMOLOGICAL SOOLETY OF ONTARIO. 



AFTERNOON SESSION— AUGUST Htji, 1894. 



The report of the committee appointed last year, on co-operation among station 

 entomologists, was presented by Mr. Smith, in the absence of the chairman. The report 

 covered the matter of concerted work upon the life-history of special insects and their 

 geographical distribution, the selection of certain groups of species to be studied from 

 year to year, co-operation in experimentation with insecticide machinery to avoid dupli- 

 cation, and suggestions in the matter of securing conjoint hgislative action among the 

 States. The report was accepted and ordered to be printed, so that opportunity might 

 ■be afforded members to examine it, in order to be able to take definite action on its adop- 

 tion at the meeting of 1895. 



A letfer from Miss Eleanor A. Ormerod was read by the President, in which she 

 expressed her regret at being unable to be present at the meeting 



A paper by Mi-. J. ]M. Aldrich, on spraying without a purap, was read in his absence 

 by Mr. Davis. This paper described a schume for the mechanical mixture of water and 

 oil by the use of an ordinary Nixon climax nozzle, the combination of water and oil 

 being made in the nczzle itself. 



In the next paper Mr. C. L. Marlatt gave a review of a number of experiments 

 conducted during the present year with severil standard insecticido mixtures, also a 

 series of experiments testing certain of the more important new insecticides or 

 substances which seem to be of value as insect destroyers recently put before the pub- 

 lic. The work was mainly to determine (1) the best methods of treating scale insects, (2) 

 the effect of various mixtures on 'rees and foliage, in both summer and winter applica- 

 tions, (3) to show the relative merits of the old insecticides compared with some of the 

 newer ones, and (4) the possibility of successfully combining insecticides and fungicides. 



The paper was discussed by Messrs. Smith, Galloway and others. 



Professor Galloway followed with a paper on various insecticide substances with 

 which he had been experimenting for a number of years past, many of them in lines 

 which had not hitherto been worked to any extent. He discussed particularly the kero- 

 sene emulsion made with lime, with resin wash, and the Bordeaux mixture. He also 

 described a new method of making resin wash devised by one of his field agents in 

 Florida, which, briefly, consisted in using purer caustic soda, causing a much more rapid 

 formation of the resin soap. Various other mixtures of possible insecticide value were 

 also suggested. The paper -vas accompanied by the exhibition of a large series of vials 

 illustrating the various mixtures and combinations described by the author. The com- 

 munication was generally discussed, and the important point emphasized that none of 

 the emulsions were as perfect or as permanent as the standard milk and soap emulsions 

 in common use, although some of them are possibly of value for immediate application. 



In the absence of the author the following paper by Mr. Webster was read by the 

 secretary : 



SPRAYING WITH ARSENITES rs. BEES. 



By F. M. Wkbster, Wocstkr, Ohio. 



At the Eochester, N. Y., meeting of the association, I gave the results of some 

 experiments looking toward a solution of the problem, " Will spraying fruit trees while in 

 bloom affect the bees which afterwards visit these, trees for the purpose of securing 

 either honey or any other substance carried to the hives, and if such be thf) case, what is 

 the effect upon the inmates of such hives ?" The results of my first attempt at settling 

 this question will be found on record in Insect Life, vol. v, pp. 121-123, audit will, 

 therefore not be necessary for me to repeat them here. On account of the meteorologi- 

 cal conditions under which the experiments were carried on they have never been deemed 

 conclusive in point of dehnifce results, even by myself, and I have only been waiting a 

 favorable season in order to finish the work. This year tlie time appeared to have 

 arrived in which I might hope to solve the problem.
