All of the macaroni was examined after drying but no evidence of live 
insects had been found even though the macaroni had been kept under 
observation and carefully examined from time to time. 
Conclusions 
In the above experiments no stages of the granary weevil (Calendra 
granaria) survived the process of milling semolina even though the wheat 
was very heavily infested. 
The adult beetles did not lay eggs in the semolina even though left in 
it until they died. 
When parts of the wheat were cut away experimentally leaving the 
eggs in granules similar to those of semolina, the larvae were unable to 
develop. This is the condition which would arise if eggs did pass 
through the mill in such granules. 
None of the macaroni made from the infested semolina was infested 
with any insects or eggs even though all the semolina came from badly 
infested wheat. Part of the semolina had contained adult weevils, and 
some of the dough had all of the stages of flour beetles placed in it just 
before it was pressed into macaroni. 
This means that macaroni contains no living insects or eggs in any 
stages as it comes from the press. This is in spite of whether the wheat 
or flour or semolina may have contained weevils or flour beetles.
