A Fungus Parasite un the Godlin Moth. 471 



Conclusion. 



The parasitic fungus on the codlin moth larva is easily propagated, 

 and the spores are readily produced. The spores may be sprayed in 

 water, at the same time as other spraying mixtures are applied along- 

 side, and the results of both noted and compared. If by this means 

 an epidemic could be spread among the grubs so as to effectually 

 reduce their numbers, it would be a simple way of dealing with the 

 pest. It would seem however, that it is only in certain seasons and 

 in certain localities that the fungus is produced in sufficient abundance 

 to produce noteworthy results, and it could only be used at present as 

 an addition to, and not as a substitute for, other means which have 

 proved themselves to be more or less effectual.
