90 DECIDUOUS FRUIT INSECTS AND INSECTICIDES. 
Since the life cycle is considered to begin with the appearance of 
the eggs, it becomes first completed with the appearance of eggs from. 
moths of the same generation. The average period between the 
emergence of moths and first oviposition must therefore be added to 
the life cycle and not, as might be thought, the length of life of the 
moth (see Tables XX VI and XXVII). The sum total of the averages 
for the stages together with the average of 5 days for the oviposition 
(see Tables XXIV and X XV) makes 58.28 days; the average for the 
life cycle of individuals reared through all stages together with 5 days 
for oviposition was 58.68 days.
