202 HOUSEHOLD INSECTS 



general idea that the immature stages of insects are 

 much more subject to the effects of varying degrees of 

 temperature than of even and continuous temperatures. 

 In the light of these experiments, it is suggested that 

 cold storage companies subject the goods in their care to 

 low temperatures for a few days and then allow them to 

 rest for a few days at higher temperatures, followed again 

 by cold. Such variations of temperature would actually 

 kill all the moths and larvse that might be hiding among 

 the goods, after which they could be stored at a uniform 

 temperature of 40 degrees with perfect safety.
