beetle (^Chilochonis dmiUx), which is ('I'licioiU in kec[)iiij^f \\w 

 scale in cheek in its native lioniu. li has not ms xcX proved, 

 however, an equal success in Anii'rica. 



Other cases in point are the Hessian llv, cahija^r hniltTlh-, 

 codling moth, ehn-lcaf beetle, iniporte<l currant lly, and many 

 more; and these illustrate the almost irri'sistil)lc power of an 

 insect species when supplied w ith abundant food and ndim'ed 

 from its natural enemies. They also emphasize the need of 

 watching all ports of entry with extreme care to prevent such 

 expensive importations. 



All work \\'ith insect enemies reveals the absolute necessity 

 of the general dissemination of a knowh^lge of tlie })roblems 

 involved. One ignorant or careless importation may cost the 

 whole country irreparable loss. A neglected garden or orchard 

 is often a menace to an entire neighborhood, l-'or one indi- 

 vidual to try to hold such natural forces in check is discour- 

 auLUP" and well-nioh hoi)eless. In the successful handlinL!' of 

 such problems all members of a community must iniite. Each 

 nmst know and do his duty and his part. If one person can- 

 not or will not [)revent his trees from breeding insect pests 

 that damage his neighbors, he sliould promptly cut them (h)\\ n 

 and burn them up. This law of nature applies with special 

 force to the intelligent protection of birds and other insec- 

 tivorous animals, in which all members of the conununity 

 sliould unite.
