THE KANSAS CHERRY. 89 



and burned. When found on cultivated trees, the diseased portions should be 

 at once cut out to at least three inches below the knot and burned, and the wound 

 treated with a strong ten-per-cent. solution of copper sulphate. If the work is 

 done while the trees are dormant, they can be sprayed with the same solution, 

 which will be likely to destroy any spores resting on the trees awaiting a favor- 

 able time for development. Where the knots are cut off, after treating the wound 

 with iron sulphate, cover with a linseed-oil paint. 



BROWN EOT. 



The cherry, like the plum, only more so, suflPers from brown rot, 

 produced by the fungus Manilla fructlgen a. It must be treated as 

 directed in case of the peach. 



CHERRY APHIDE. 



The worst insect enemy of the cherry in the Carolinas is the cherry 

 aphide or louse, Myzus cerasi. This pest resembles the aphides of 

 the apple, peach and plum, and must be treated in the same way. 

 The leaves only are attacked. 



THE JUNE BEETLE. 



The cherry is also attacked by the June beetle, already treated of, 

 and which must be combated as prescribed for the peach. 



THE DOG-DAY CICADA. 



The dog-day cicada, Cicada tuhicen, an annual species, resembling 

 somewhat the seventeen-year periodical cicada, is sometimes trouble- 

 some to the cherry by puncturing the small twigs and laying its eggs 

 therein. These eggs hatch and the larvae enter the ground, but com- 

 plete their development in one year. 



Remedies : Gather and burn all twigs slowing the slits or nests of 

 this insect. 



THE FRUIT-TREE BARK-BEETLE. 



From Kansas.Experiment Station Bulletin. 



Of the insects that have been introduced into this state during the 

 past few years, none seem to be more destructive to stone-fruit trees 

 than the fruit-tree bark-beetle, or shot-borer, as it is sometimes called, 

 from its peculiar habit of riddling the bark of the trees with numerous 

 small holes. The insect has been found in Riley, Bourbon and Allen 

 counties, and without doubt is present in a large number of the other 

 counties of the state. In Allen county it was very numerous, laarticu- 

 larly in an orchard of cherry trees which were suffering badly from 

 the cherry scale {Aspidiotus foi'hesi). 



The presence of the pest will probably be first shown by the wilt- 

 ing and falling of the leaves at an unseasonable time. A close exami- 

 nation of the tree infested with the insect will reveal numerous small 

 holes in the bark, from which in the case of the stone-fruit trees, such
