Insect and Disease Control 251 



roughened spot such as a curculio sting or a hail scar. 

 The larva feeds in various positions in the fruit. Brown- 

 rot is Hkely to attack the fruits thus injured, and it may fall 

 to the ground, though much of the infested fruit remains 

 on the tree. If its work progresses far enough in the fruit 

 its presence may be apparent, but in much of it, especially 

 if entrance is made near the stem, the presence of a worm 

 is unsuspected so far as any apparent external evidence is 

 concerned. 



There are probably two or three broods in a season, but 

 the insect in its various stages may be found throughout 

 the season. 



The seriousness of this p>each moth as a peach menace rests 

 in the two facts of its apparent ability to cause great damage 

 both to tree and fruit, and in the absence at present of any 

 known method of control. 



Peach budrmite (Tarsonemus waitei) 



This insect is a menace to nursery stock rather than to 

 bearing peach trees, but brief reference to it in this connec- 

 tion seems not out of place. 



For the past twenty or twenty-five years, occasional 

 instances have been reported of serious trouble with peach 

 nursery stock which manifested itself in the young trees be- 

 coming very much branched, the small secondary laterals in 

 turn frequently branching profusely as well as the main limbs. 

 As a result the trees are dwarfed and fail to grow to the re- 

 quired height and because of their inferiority are unsaleable. 



It has been quite conclusively proved that this trouble 

 is due to the killing of the terminal bud of the twigs by the 

 very minute insect or "mite'* here in question.
