CHAPTER VI 



Artificial Remedies. 



It will be seen from the foregoing account of the natuval 

 checks to tlie increase of these insects that in nature, under 

 normal conditions, there is no abnormal increase and conse- 

 quent injury. It ma}^ further be seen that, when we have 

 removed many of these natural checks and the insects are 

 thereby permitted to increase in destructive numbers, we must 

 resort to artificial remedies if we would again restore original 

 conditions. 



The present chapter will, therefore, be devoted to a discus- 

 sion of various artificial methods of destroying the locust in its 

 different stages of growth unaer some of the conditions in 

 which it may occur. We will try to show how the eggs, mos- 

 quitos, saltonas and voladoras may be handled at a minimum 

 expenditure of labor and money. These remedies must there- 

 fore be selected in accordance with the insect's habits and the 

 governing circumstances under which it is found. In these 

 selections of remedies we must also try to be governed more 

 or less by what is nearest at hand or most readily obtainable 

 at the time and place. Where the expenditure of money can 

 be avoided this should be done, provided good results can be 

 obtained without such outlay. 



Destruction of eggs. 



In the artificial destruction of locusts the eggs may receive 

 our attention first. On account of the great depth at which
