black locust plantation. In 1977, however, under 

 forest conditions, some animals were caught in the 

 traps. Mice climbed the trees and got stuck in the 

 Tack Trap, which in turn attracted blow flies and 

 carrion beetles; this quickly made the traps use- 

 less. A small band of Tack Trap applied on the 

 tree about 30 cm above the ground will keep mice 

 out of the traps. Flying squirrels and birds were 

 readily trapped until it was discovered that if the 

 diameter of the trap did not exceed the diameter of 

 the tree by more than 16 cm the animals were 

 apparently able to jump clear of the tray after 

 contacting the sticky band. No birds or flying 



squirrels were caught in the smaller traps. Thus 

 the traps appear to be useful for some survey and 

 test situations. Some modifications of the traps 

 may be necessary, depending upon the research 

 situation and the insect species involved.
