Unlike many in its family,

d 

 rom 

 May to October when the beetle is 

 active. This strategy, however, 

 would result in unacceptable levels 

 of chemicals in populated areas and 

 would be impractical, if not impossible, in forested 

 ones. As a result, the solution has been to cut down 

 all infested trees, then chip and burn them. The re- 

 maining stumps are ground to a depth of up to 18 

 inches below the surface. To further limit the beetles 

 spread, quarantines have been placed around all in- 

 fested areas to prohibit the movement of trees and 

 tree materials. The war against this pest continues in 

 New York and now in Chicago, with its discovery 

 there in the summer of 1998. However, it isn't the 

 only beetle battle being waged. 



The smaller Japanese cedar long-horned beetle, 

 CaUidiellum ruftpenne, was discovered in Connecticut 

 on September 22, 1998, where it arrived on an arbor- 

 vitae from British Columbia. It has since been found 

 in three other Connecticut locations. This deep blue- 

 to-black beetle with a reddish abdomen is also a 

 wood-borer that attacks arborvitae, juniper, cedar, and 

 pine trees. Moveable in all of its living stages in in- 



the Asian long-horned beetle 



attacks and kills healthy trees 

 along with stressed ones. 



fested wood and wood products as 

 well as in live trees, it has the poten- 

 tial to affect the nursery and green- 

 house industry. Because of the fall 

 discovery, it is believed the beetle 

 hasn't become established. However, 

 the assault has begun. Connecticut has quarantined 

 the movement of nursery and greenhouse stock in and 

 out of the state, and "Wanted" posters are about to 

 come off the press to alert the public in an attempt to 

 squash this new "bad bug." 



The greatest chance of eliminating either beetle 

 comes through awareness. The success in getting the 

 Asian long-horned beetle population down has been 

 an informed and involved public. It is hopeful that as 

 the Japanese cedar long-horned beetle emerges from 

 exit holes into new territory for the first time this 

 coming spring, an informed public will be ready and 

 waiting to bid it goodbye.
