THE IMPORTED CABBAGE WEBWOEM.

The moths which issued December 11 deposited eggs for a succeed- 
ing generation. Unfortunately, it was necessary to abandon the work 
at this point and records of further development were not obtained. 
EGG-LAYING RECORDS. 
On October 11 a pair of moths, which had issued that day, were 
observed mating. These moths, while still together, were put into a 
separate cage and the following record obtained :

The female died October 21 and the male died the following day. 
The female lived 10 days and deposited 235 eggs. The male lived 
11 days. 
With another mating pair, which were likewise confined during 
October, the female lived 11 days and deposited 237 eggs. The male 
lived 17 clays. 
The life-history records were obtained in an open-air insectary in 
which open wire cages were used. Food was supplied the moths by 
putting in wads of absorbent cotton which had been saturated with 
molasses and water. They fed on the diluted molasses eagerly. The 
moths were docile and easily handled, and mating pairs were readily 
obtained during the daytime. In all cases, cabbage was used as food 
for the larvae. Usually young, tender plants from seed beds were 
supplied.
