PROCEEDINGS OF THE SUMMER MEETING.

enough to give it a faint green tinge. This is meeting with good results 

 in many peach orchards in the east. The theory is that as the young 

 grub hatches from the egg and commences to gnaw through the bark, it 

 eats enough of the poison to kill it. One thorough whitewashing about 

 the first of July would be enough for the year, and it looks to me like 

 the simplest and most practical method we can use. 



SHOT HOLE BOREK. 



On several occasions the past few years we have received specimens 

 from South Haven of peach tree trunks killed by this minute beetle. ' 

 The beetle is closely related to the clov.er root borer that is killing all 

 our clover in central Michigan. Like the clover root borer, too, it selects 

 thrifty, healthy plants for its work. The holes made in the bark remind 

 one of a charge of fine shot having been fired into the tree. The first 

 efPect noticed is of the leaves turning yellow as in a tree suffering from 

 peach yellows, and the leaves will drop off, the bark will crack, and the 

 tree gradually dies. The beetle is said to be much more common on elm 

 trees than on the peach. According to Harris, in his "Insects Injurious 

 to Vegetation," it completes its transformations in August and September. 

 We have taken it in early June at the college, and I am inclined to 

 believe that this is nearer the time when the beetles appear. They then 

 bore into the bark and the females lay their eggs singly along the cham- 

 bers cut in entering. They work on the trunk and larger limbs. 



Nothing has ever been done, to my knowledge, in the use of remedies, 

 but I am very sure that the same poisoned whitewash as recommended 

 for the common borer, when applied before the beetles enter to deposit 

 eggs, would catch them the same as the young grubs of the borer. Trees 

 that are already bored by the beetle and show signs of injury or death 

 should be cut out and burned at once to kill the occupants and prevent 

 their escape to attack other healthy trees. 



SNOWY TKEE CRICKETS. 



Sometimes snowy tree crickets will 



become numerous enough to injure 



young peach twigs by laying their 



eggs in a row along the twig. The 



white eggs are somewhat curved and 



are put into the twig close together, 



often extending in a row for several 



inches. This can be seen nicely by 



splitting the twig lengthwise along 



the dead crack. The reason the tree 



cricket is spoken of here among 



borers is, that every little whilp 



people send me twigs containing the 



opln.^^* ^^^'^ ^^^ ^ggs and want to know what grub it 



is at work in the limbs. Crickets 



do the trees little harm, as they do not feed on them,. 



merely laying the eggs there in the fall for winter 



protection. The snowy crickets are lovers of weed' 



patches and will seldom bother cultivated plants if 



the weeds are well subdued in an orchard. Cutting 



off the injured twigs in the fall or spring and burning 



will rapidly deplete their numbers.
