for its other disadvantages. We can conceive that any one planting in 

 any one year might largely escape ear-worm by not being in tender silk 

 when the adult moths were out in numbers. But we are not able to 

 forecast the broods with sufficient exactness (nor can we know the rate 

 with which the corn will grow) to make any positive recommendations 

 on this point. 



Let us hope that better remedies may be developed in the future. 



WEEVILS (Several Species). 

 Orders Lepidoptera and Coleoptera. 



Description. — Small or medium-sized insects which in the adult or 

 larval state, or both, injure grain by eating into the kernels when stored, 

 or by eating the meal or other products. Sometimes attack corn in the 

 field before harvest. Often troublesome in mills, barns, stores, pantries, 

 etc. The adult insects are moths or beetles. 



Injury in North Carolina — There are from eight to a dozen distinct 

 kinds of "grain weevils" in North Carolina, and the total damage by 

 them is great. Prof, R. I. Smith during some special studies of our 

 grain weevils recorded at least nine species as known to him.^ These 

 were: 



(Lepidoptera) (Moths) : Angoumois Grain Moth, 



Indian Meal Moth, 



Meal Snout Moth. 

 (Coleoptera) (Beetles) : Saw-toothed Grain Beetle, 



The Cadelle, 



Yellow Meal-Avorm, 



Dark Meal-worm, 



Granary Weevil, 



Rice Weevil ("Black Weevil"). 



Undoubtedly the most destructive "weevil" to our corn is the last one 

 in the above list — the "Rice Weevil" or "Black Weevil." It has been 

 sent in to us more often than any other kind. It appears to be the 

 hardest of all the weevils to control. It also often infests the corn in 

 the field, as the following letter from the southeastern part of the State, 

 received August, 1912, shows: 



"A year ago a large quantity of corn here was destroyed by weevils before 

 taken from the field. This year a great deal of the early corn has one or two 

 dozen weevils on each ear, and as the corn hardens it is being damaged." 



Many other letters could be quoted shoAving this same general condi- 

 tion.
