CLASSIFICATION OF REMEDIAL MEASURES. 
Preventive and remedial measures against insect attacks may pe 
conveniently arranged under five general heads: 
1. Methods of culture, including the preparation of the soil. 
2. Barriers to progress. 
3. Capture and direct destruction. 
4. Topical applications. 
5. Protection, or artificial multiplication, of natural enemies. 
1. Under methods of culture we include all measures like rota- 
tion of crops, selection of time of planting, and the like, which are 
intended to take advantage of the insect through some fact in its 
structure, habits, or life history.
