BARK BEETLES 



Any insect boring in the bark might 

 be called a bark borer, but the typical 

 or true bark borers belong to the fam- 

 ily of Scolytids and to the group 

 known as snout beetles. There are 

 over 20,000 species of snout beetles 

 but only a few hundred of them are 

 of economic importance. 



A bark beetle is a small insect prob- 

 ably never more than a quarter of an 

 inch in length and it may be as small 

 as a sixteenth of an inch. The pre- 

 vailing color is brown to black. The 

 head is usually doubled under the 

 thorax while the end of the abdomen 

 may have characteristic spines, ridges, 

 or hairs which are the basis of deter- 

 mination of many species. 



Most of the bark beetles and borers 

 work between the bark and wood, in 

 the vital tissues of the tree. A few 

 groove the wood while others confine 

 themselves to the inner bark. The 

 greatest injury, of course, is done by 

 those working in or near the cambium 

 layer. An entrance is made by the 

 adult through the bark. This hole is 

 small and often it extends upward 

 thus giving a protection from weather 

 and possibly from other sources. When 

 the bark has been penetrated a verti- 

 cal transverse tunnel is made along 

 the sides of which the eggs may be 

 placed in nitches or the brood chamber 

 may be widened and the eggs packed 

 along the sides. The larvae bore out 

 into the tender tissue following defi- 

 nite lines or extending the tunnels in 

 every direction. As the larvae in- 

 crease in size the tunnels become 

 wider and if the insects are abundant 

 the flow of sap is checked and the 

 tree or part of It attacked may be 

 girdled in a comparatively short time. 



The only sure control is the com- 

 plete destruction of Infested parts. 

 Twigs, branches, or whole trees should 

 be burned or the bark removed and 

 burned immediately or at least before 

 the first of May to prevent the emerg- 

 ence of the adults.
