Insects Attacking the Pecan 179 



corn, cotton, and small grains. These insects have a life 

 history which extends from one to three years, and in 

 localities in which they are abundant outbreaks may be 

 expected at such intervals. The June-bug feeds at night 

 and cuts small pieces from the leaves and at dawn hides 

 under piles of leaves or any kind of rubbish which may be 

 at hand. 



The best way to control these insects is in the larval stage 

 by plowing up the ground in winter and exposing the pupae 

 and larvae to the elements, attacks of birds, and other similar 

 agencies. This is not always possible, and under such condi- 

 tions the trees may be sprayed with arsenate of lead at the 

 rate of two pounds to fifty gallons of water. 



RED-SHOULDERED SHOT-HOLE BORER 



(Sinoxylon hasilaris, Say.) 

 Several closely allied beetles often attack pecan trees, boring 

 small holes at the juncture of the two limbs or sometimes enter- 

 ing small trees and entirely girdling them by cutting a cir- 

 cular channel just under the bark entirely around the trunk. 

 No remedy is kno^^^l for this class of damage, but as these 

 insects more often attack trees in a weakened condition, pre- 

 cautions may be taken to keep them healthy. It is possible 

 that a repellent wash would keep the beetles from working. 



SCALE INSECTS 



The pecan is not immune to scale insects. They have not 

 become of sufficient importance, however, to necessitate spray- 

 ing as is the case for apples, peaches, pears, and other orchard 

 fruits.
