Summer Meeting. 55 



these larvae come forth and feed upon the opening and expanding buds 

 and terminal shoots, and do a great amoimt of injury by holding the 

 trees in check and also preventing the fruit buds from opening. In 

 about three weeks the larvae become full grown and then transform to 

 pupae ; and then along in the middle of the summer appear as moths, 

 which lay eggs in a short time for another brood, which larvae pass the 

 winter as above described. 



As young orchards are more apt to be injured by these insects than 

 full bearing orchards, it sometimes becomes an easy matter to pass 

 through the orchard and pick these crumpled up leaves off, together with 

 the cornucopia-shaped cases. Carless work will result in merely removing 

 the leaves and allowing the cases to remain on the trees. If, however, 

 the tree is so large than one cannot readily reach them from the ground, 

 a better method is to wait until the buds expand and the larvae become 

 active, and then spray the trees with arsenate of lead. 



It is perhaps unnecessary to say that trees should not be sprayed 

 while in full bloom, not so much on account of the liability to kill bees, 

 as on account of the fact that the spray is apt to injure the stigma and 

 prevent pollination. 



Another insect causing a great deal of injury this year is the Buffalo 

 Tree-Hopper. This triangular-shaped insect deposits her eggs in the 

 latter part of the summer inside the twigs of apple trees especially, and 

 where numerous, may seriously injure your trees by checking the growth 

 of the twigs. The places where the eggs are deposited fail to grow and 

 develop, which injures the twigs according to the number of punctures in 

 the same. In the spring of the year the eggs hatch into small hoppers, 

 which drop to the ground and feed upon weeds or various kinds about 

 the orchard and neighboring fields, and injure them by sucking the sap 

 from the same. They do not disturb the apple trees until the female 

 wishes to deposit her eggs in the same, hence the best way to fight 

 this insect is to destroy all weeds about the orchard and neighboring fields, 

 thus doing away with the feeding grounds for the insect, and therefore 

 the orchard will escape the attack of this insect in the fall. 



In the spring of 1907 there will appear over this locality another 

 brood of the Scz'eiif ecu-Year Locusts. As these insects are likely to occur 

 here in large numbers and deposit their eggs in the young orchards, it 

 is advisable not to plant orchards in the fall of 1906 or the spring of 1907, 

 unless you either run the chance of the insects not getting into them or 

 are so arranged that you can immediately spray the orchard with white- 

 wash just as soon as the locusts commence to deposit their eggs in the 

 twigs. The injury which these seventeen-year locusts do is similar to that
