COMMUNITY EFFORT IN INSECT SANITATION. 
The Angoumois grain moth has never been fought vigorously by 
farmers. Certain few men protect their crops and reap a saving. 
Many farmers wake up too late and find their crops already badly 
affected. Lack of labor and thrashing machines force some farmers 
to do the best they can. But all farmers can support a campaign in 
their own communities to kill out the Angoumois grain moth. Ex- 
periments have proved that the moth in the region of winter wheat 
can not live through the winter in the grain sown in the fall. Hence 
farmers can center their attack upon the pest in the cribs and’ 
granaries. Farther South the pest may live through the winter in 
grain left in the field. Zhe county agents representing both State 
and Federal departments of agriculture should interest farmers in 
their counties in campaigns along the lines of insect sanitation. No 
pest can be more effectively controlled than the Angoumois grain 
moth. Success in this mode of attack in the northern range of the 
habitat of the pest depends upon the thoroughness with which 
farmers combine to treat infested grain in storage, and in cleaning 
. out their cribs in the spring. In the more southern States success 
depends upon removing the crop thoroughly from the field as well 
as attending to disinfection in the crib and cleanliness of the crib 
after the crop has been removed from it. Dr. L. O. Howard first 
recommended control of the Angoumois grain moth through com- 
munity effort over 25 years ago. 
If county agents in sections where the moth is injurious can unite 
farmers in a campaign of control they will save the farmers of their 
counties grain worth many times the salaries paid them. Intelligent 
insect sanitation pays handsome returns.
