826 CONNECTICUT EXPERIMENT STATION REPORT, 1907-1908. 



been a wet season, many of the beetles would probably have been 

 killed by the fungous disease which attacks them. 



The damage has nearly all been done for this season, as the 

 partial second brood is usually of little account. The larvae or 

 grubs are now crawling down the trees to transform to pupae 

 at the base. Many property owners have placed bands of sticky 

 fly paper around their trees and have caught some of the larvae, 

 but most of them are prevented from coming down and will 

 transform above the bands. It is probably better to let them 

 descend where they can be reached easily and killed. 



The bright yellow pupae at the base of the tree and lodged 

 in the crevices of the bark should be destroyed at once. This 

 can be done easily by spraying them with kerosene emukion or 

 common laundry soap dissolved in water at the rate of one pound 

 in eight gallons. They can also be swept up and burned or 

 dropped into a pail of kerosene or of hot water. 



Prompt action is necessary, for the pupa stage lasts only ten 

 days, when the beetles appear and fly away. They do but little 

 feeding, and go early into barns, attics and church belfries, where 

 they pass the winter. The beetles can sometimes be gathered in 

 large numbers and should always be destroyed. 



Trees which have lost their leaves this season should be sprayed 

 with poison (three pounds lead arsenate in fifty gallons of water) 

 next year to preserve the foliage, for if completely defoliated for 

 two or three seasons successively the trees will die. The poison 

 should be applied in the form of a spray directed against the 

 under surface of the leaves, where the larvae or grubs feed. 



People always become excited and wish to "save the trees" 

 at this time of the year, after the damage has been done for the 

 season. They should begin earlier, and spray the trees in time to 

 prevent the injury. 



WHAT TO DO. 



1. Destroy all of the bright yellow pupae at the base of the tree 

 and' in the crevices of the bark. 



2. Hunt for beetles in houses, barns, attics, church belfries, 

 and out-buildings during the fall, winter, and early spring, and 

 destroy them. 



3. Arrange to spray the trees with poison next year.
