GUMMING. 
See discussion of gumming of stone fruits under gumming of 
the peach, page 438. To prevent gumming in the forks of cherry 
trees Wickson™ advocates training the tree in such a way as to 
give wide, open forks where the branches join the trunk. 
CHERRY INSECTS. 
CURCEELO: 
This insect injures cherries by causing the fruit to become 
wormy. It is the same insect as the plum curculio and is dis- 
cussed more at length under the subject “ Plum cureulio,” on 
page 454. 
Treatment.— The cureulio is commonly fought in cherry or- 
chards by one or two applications of Paris green or its equiva- 
lent at the rate of one pound to three hundred gallons of water. 
Two or three pounds, at least, of unslaked lime should be added 
for every pound of the poison. Slake the lime and add to the 
mixture the same as in making Bordeaux mixture. The poison 
may be mixed with the Bordeaux mixture if desired as stated on 
page 417. Make the first application immediately after the 
blossoms have fallen and a second about ten days later. 
FRUIT BARK BEETLE. 
This is the same as the fruit bark beetle of peach discussed on 
page 442. 
MAGGOT. 
(Rhagoletis cingulata? Loew.) 
This insect resembles the apple maggot in all of its stages. It 
attacks sour cherries and probably plums to some extent. It has
