Strawberry Culture q.r 



from the leaves to the roots, where they take care of them. They 

 are instrumental in spreading them. As ants also care for the 

 corn root-louse and the melon louse, fields in which these crops 

 were grown the previous year, if they were infested, are likely 

 to be full of ants' nests. If such fields are planted to strawberries 

 and root-lice appear, the destruction wrought by them will be 

 the greater. The chief enemies of these aphids are internal para- 

 sites. Lady birds and their larvae also feed upon them. 



The best preventive is setting clean plants on clean ground. 

 Land which is infested should be worked thoroughly in other 

 crops for at least a year. Plants should be secured from patches 

 which are not infested or else fumigated with hydrocyanic acid 

 gas. "Plow under old infested beds before May first or locate 

 new beds as far from them as possible. No successful remedial 

 measures are known." 



STRAWBERRY WEEVII, (Anthonomusmusculus). Mr. Hugh 

 N. Starnes, of the Georgia Station, said of it in 1896, "a small 

 black beetle, sometimes attacks the buds and blossoms of the 

 strawberry, destroying the stamens of the bi-sexual varieties and 

 ruining them both for fruit and for purposes of pollenization. 

 Kerosene emulsion or white hellebore have been suggested as 

 remedies the plants to be sprayed as soon as the buds are set." 

 Professor Beckwith, of the Delaware College Station, in 1892 

 reported investigations made by him, in which he found that 

 pistillate varieties were seldom attacked and that the larvae pene- 

 trated the ovary of the blossom, where they remained until the 

 perfect beetles emerged. Their presence in the ovary is mani- 

 fested by the blasting of the blossom, the pistils turning black. 



STAI^K BORER (Gortyna nitela). The late Dr. Lugger, of 

 Minnesota, said this pest has in some cases devoured the fruit
