198 SECOND REPORT OF THE STATE ENTOMOLOGIST. 



bran will soon find their way to it, apparently guided by the sense of 

 smell, as those to the leeward of the bran have been observed to come 

 to it from a greater distance than those which were upon the side of the 

 bran from which the wind was blowing. After eating as much of the 

 bran as they desire, the grasshoppers usually crawl off, and many hide 

 themselves beneath weeds, clods of earth, etc., and in a few hours will 

 be found to be dead. 



The mixture costs from thirty-five to forty cents per acre of vineyard, 

 including labor of mixing and applying it. In orchards the cost will be 

 considerably less than this. One man can apply it to eight or ten acres 

 of vineyard in a day. 



I have seen this remedy tried on an extensive scale at the vineyard 

 and orchard of Messrs. Kohler, West and Minturn, at Minturn station, 

 Fresno county. In that part of the vineyard which was the most 

 thickly infested by grasshoppers from thirty to fifty dead grasshoppers 

 Avere found beneath almost every vine, while beneath the adjacent weeds 

 were hundreds of others, the greater part dead. It was also very effect- 

 ual when placed beneath small fruit trees, the grasshoppers leaving the 

 trees to feed upon this mixture. 



The addition of sugar to this mixture is merely to cause the arsenic 

 to adhere to the particles of bran, and not for the purpose of increasing 

 its attractiveness, since it was found that the grasshoppers were not at- 

 tracted to pure sugar. Middlings or shorts have been used in the place 

 of bran, but are not so desirable, since in drying they assume a solid 

 mass which the grasshoppers cannot eat, whereas bran in drying never 

 assumes a solid form. — D. W. Coquillet, Atwate?', MercedCo., June 27.]
