Bedbugs 



Girault, A. A. Preliminary studies on the biology of the bedbug (Cimex lectu- 

 larius) 1. The effect of quantitatively controlled food supply on development. 

 Jour. Eco. Biol., October, 1910. Reduced quantity of food did not affect reproduc- 

 tion or sex but lengthened the cycle indefinitely, reduced the size and increased the 

 number of ecdyses. 



Survival of bedbugs. A note in Jour. Amer. Med. Assn., June 11, 1910, refers 

 to an experiment made by Dr. W. Hapgood in which he kept the bugs in a bottle 

 without food for nearly six months.

 insects, probably lice.

 The fever was transmitted from monkey to monkey and from man to the monkey 

 by the louse.
