not siti-.iycd. An insect Ilia I is so easily conibatted as this should 

 not be permitted to Ihtoimc so abundant as it was in our State last 

 year, A spray with paris j>reen — one pound in one hundred and 

 fifty gallons of water, just after the petals fall, and again in ten 

 days — will be sufficient to insure against the Codling Moth. 



Upon (hes(! and other fruit trees the Oyster-shell scale and the 

 Scurfy scale have been reported to us by hundreds of persons. The 

 remedies for these are similar to those which we have published 

 for the San Jose Scale. 



(j.) Dupraceous Fruits: Peach, Plum and Cherry. — The San Jos^ 

 Scale has also been the chief enemy of these fruits, but in addition 

 to this the plum curculio has been very abundant and destructive. 

 The chief remedy still to be advocated for this is the old method 

 of jarring the tree, and catching the beetles in a cloth or a curculio 

 trap arranged for the purpose. Some practical growers have 

 claimed excellent results by using Paris green and Bordeaux mix- 

 ture, applied as a spray. The Peach-tree borer has been very de- 

 structive, causing serious loss in our State, but we discovered one 

 grower using a simple and effective remedy. This is one pound of 

 concentrated lye in twenty gallons of hot water, and one quart ap- 

 plied while hot to the base of each tree after the mass of gum and 

 rubbish had been cleared away. 



(Iv.) On Grapes. — As far as our investigations and the reports to 

 us show, the insects on grapes have been unusually few during the 

 past year. We went to Erie county several times for the express 

 purpose of investigating the insects injurious to grapes, but at no 

 time could we find them in sufficient abundance to justify extended 

 experimentation. One person sent us w^ord that there w^ere im- 

 mense numbers of eggs of the Crape Leaf-hopper upon his vines, 

 and by examination we found them to be globules of natural ma- 

 terial or exuded sap upon the growing parts. 



(1.) In Granaries. — The Weevils (two species), the Angoumois 

 grain moth and the Mediterranean flour moth have been reported to 

 us in stored grain and in warehouses. We have advocated fumiga- 

 tion with hydrocanic acid gas or sulphur. The Flour worm was 

 reported from some of the w^arehouses of the large railroads, and 

 we advised the cleaning up of all flour and meal left in corners and 

 in cracks of floors, and the filling of cracks with some material 

 that would prevent the flour from settling there, and becoming 

 the food for these worms or beetle larvre. This prevents their mul- 

 tiplication, and appears to have been a successful method. 



(m.) In the Household. — A few^ reports of cockroaches have 

 reached us, and we have advocated rat poison or the use of powdered 

 borax, or powdered sugar and a very little Paris green or w'hite ar- 

 senic, A mixture of powdered sugar and plaster of paris in equal
