Remedies. — The question of the destruction of these insects is 

 one which will require much further study, and is, I believe, of suffi- 

 cient importance to warrant further investigation. 



In the present state of our forestry operations in California it is of 

 course impractical to spray or fumigate the forest trees, except by in- 

 dividual owners in limited areas, or where it is desired to preserve 

 some cultivated species. However, a number of species of these 

 coccidse harbor from one to several species of parasites, which in 

 most cases, except where the conditions are extremely favorable for 

 the increase of the scale insects, are very effective in keeping them in 

 check. 



The proper solution of this problem will only come with the de- 

 velopment of a proper forestry system for our extensive forest areas in 

 California, as well as in other states. When we have competent for- 

 esters and forest entomologists we can look to them to see that badly 

 infested trees are destroyed and that proper parasites are introduced.
