The average number of eggs retained by unfertilized 
females was 95. | 
(g) Comparison of the number of eggs remaining in the

of eggs remaining in the body of any unfertilized female 
was 201. The unfertilized female retained 76 more eggs

ber of eggs retained by fertilized females was 505/12. 
The average number of eggs retained by unfertilized
