SCUHART OP OVIPOSITION OF HIBERNATED WEEVILS 



Oviposition of latest first generation weevils. — The work was con- 

 cluded while the latest of the first generation weevils were still ovi- 

 positing, but somewhat desultorily. The work with these weevils 

 was, however, carried on over a period of 49 days and some data of 

 interest were obtained. Of the nine weevils, of which the lot origi- 

 nally consisted, four died without producing any eggs and one was lost 

 after five days of ovipositing. Of the four remaining, one was ovi- 

 positing throughout the 49 days, one for 44 days, and one for 43 days, 

 while the fourth had apparently ceased ovipositing after 47 days. 

 During the above periods the weevils deposited the following numbers of 

 eggs: 295, 211, 183 and 198. The average total oviposition for the four 

 weevils was 221.75 eggs. The average daily oviposition was 4.78 eggs, 

 and the maximum number of eggs deposited by any one weevil during 

 one day was twelve. These results are summarized in Table III.
