Many pods showed six egg punctures, from which live larvse, in 

 one instance, developed. It was also noticed that in nearly every 

 case where egg insertion was made beyond the middle of the pod the 

 larva was to be found slightly back of the puncture, but where the 

 egg was deposited between the stem and middle of the pod the larva 

 was located immediately underneath. The average number of egg 

 punctures to a pod proved to be about two and one-third. 



PROLIFERATION. « 



Proliferation was noticed in pods purchased in market at San 

 Antonio, Tex., October 6, 1905, and the following two series of experi- 

 ments were conducted by Dr. W. E. Hinds and Mr. W. W. Yothers: 



Experiments to determine the effects on the pepper weevil of proliferation in the pepper pods.
