Earias was relatively unimportant during 1916. Until the third 

 week of August less than one per cent of the bolls were attacked by 

 this pest. The maximum percentage was reached in the last week of 

 October. 



In actual numbers Earias reached, at its maximum, less than 300 

 bolls per thousand trees in the second week of September, having risen 

 slowly since the third week of August. 



Considering that Gelechia is an imported pest, which has been in 

 Egypt less than ten years, its increase has been enormous. It now 

 occurs everywhere, where cotton is grown in Egypt ; in the last week 

 of October, eighty-seven per cent of the green bolls in Lower, 

 seventy-eight per cent in Middle, and sixty per cent in Upper 

 Egypt were attacked by it ; and we have received specimens of the 

 adult from the desert at Romani. As to Earias it appears to have 

 sunk to the position of a minor pest, not only relatively to the 

 Pink Boll Worm but probably also absolutely.
