The pavement ant (Tetramorium. cespitum) as a pest of cold-frame and 

 greenhouse crops, L. B. Smith {Virginia Truck Sta. Bui. 16 {1915), pp. 353- 

 365, figs. 6). — During the past two years growers in the Norfolk region have 

 been sulTering losses from attacks of the pavement ant on several cold-frame 

 and greenhouse crops. This ant is a native of Europe, which was introduced 

 into the United States probably 150 years ago, since which time it has become 

 quite widely distributed throughout the eastern part of the country. While it 

 leads a more or less rural life in its European home, in this country it has be- 

 come a house pest in cities and towns, but not having until quite recently been 

 reported as injurious to crops. 



"The habit of the insect in making its nest under concrete floors, walks, or 

 pavements renders it somewhat difficult to control. Two species occur in this 

 region which might be confused with the pavement ant, the red ant {Monomo- 

 rium pharaonis) and the little black ant (J/, minutum). These can be dis- 

 tinguished by their smaller size and difference in coloration. 



"The pavement ant has been observed to feed on the following vegetables: 

 Kohl-rabi, cauliflower, cabbage, eggplant, Brussels sprouts, pepper, tomato, 

 radish, parsley and lettuce. The attacks occur to the roots, crown, and lower 

 portion of the stem. The injury to the stem and crown resemble that caused 

 by cutworms. Injuries to the roots might often pass unnoticed were it not for
