at another site, such as a barn or empty cabin One 

 precaution is necessary, the mini-vac or the vacuum 

 cleaner should be clean or have a new collection bag, 

 as large quantities of dirt and dust will probably kill 

 the beetles. This method will save ladybugs that will 

 help control insect pests next year. 



What we are probably seeing now in the East is a 

 MCALB population boom, which will probably go down 

 over the next few years Alien species that become 

 successfully established in new regions of the world, 

 free from their previous natural enemies may increase 

 dramatically. In a few years, as they are discovered 

 by new natural enemies, their population often de- 

 clines and eventually reaches a state of equilibrium. 



However, since this species Is new to New England, 

 no one can be certain of what its full impact will be 



as a biological control agent Some early research at 

 the University of Connecticut suggests that this spe- 

 cies may be an effective predator of Red Pine Scale. 

 Preliminary observations in the laboratory show that 

 IVICALB will feed on Hemlock Woolly Adelgid, a exotic 

 pest which threatens to devastate the Eastern Hem- 

 lock. Needless to say. New Hampshire would not be 

 the same without its magnificent stands of hemlock, 

 and I am certainly cheering in favor of tfie MCALBs. 



Thanks to tfie Multicolored Lady Beetle, there is 

 much excitement to look forward to this year, as we 

 all may be in for a trick-and/or-a treat this Halloween
