THE CHEESE SKIPPER AS A PEST IN CURED MEATS 51 



The biology of Piophila casei reveals no excuse for neglecting, 

 during the skipper-fly season, to protect cured meats with fine screens, 

 glass cases, or low temperatures from the time they leave the curing 

 vats until they are either wrapped or rapidly carried through trade 

 channels to the consumer. There may be economic reasons for 

 avoiding the expense of protection, and in each case the risk of loss 

 through skippers should be balanced against the cost of preventing 

 such damage. 



LITERATURE CITED 



About 170 references to Piophila casei are to be found in the litera- 

 ture of entomology. A few more than half are omitted from the 

 following pages because they largely duplicate previously published 

 data. 



Illustrations of the insect which are especially worthy of note are 

 to be found in papers by Alessandrini (5), Banks (10), Dufour (19), 

 Mote (SI), Sakharov (67), and Swammerdam (73, pp. 63-76). 



The principal contributions to the biology and control include : 

 Alessandrini (4, 5), Bachmann (9), De Ong and Roadhouse (18), 

 Howard (32), Kellogg (37, pp. 114-115), Kessler (<?£), Krausse (1,0), 

 Mote (51), Murtfeldt (53), Ormerod (51,), Redi (58), Sakharov 

 (67), Swammerdam (73), Willard (80), and Wille (81).
