Admittedly the grapes were picked prematurely. If 

 sprayed, this quite likely interferred with their eating quali- 

 ties. The expenses, I pointed out in my Circular No. 140, p. 8, 

 were many times that of using the torch. I also pointed out 

 that there was no need to injure the vines or fruit, if present, 

 since the application of heat could have been made lighter, but 

 be made repeatedly. These bugs, moreover, readily drop dur- 

 ing the cool part of the day. The application could have been 

 given during the night, or anyway early or late in the day 

 when the dew is on, with the bugs sluggish and more liable to 

 drop, to be killed at the ground at close range. 



Alfalfa is given by Dr. Morrill as the crop the conchuelas 

 are most likely to congregate on in largest numbers in the 

 spring, and he points out that with no means of control prac- 

 ticed, the bugs will multiply there unchecked. As a means of 

 control, he suggests leaving a border of alfalfa all around at 

 cutting time, on which the immature forms will congregate, 

 to be killed by kerosene emulsion. This, of course, is awfully 

 expensive on such a bulky crop ; also may make this alfalfa 

 nearly or entirely unfit for feed. The use of a knapsack torch, 

 as shown on last page, or a mounted outfit, having several 

 burners, would be much better. Moreover, the adults will not 

 stay there, not only because other crops will offer as good or 

 better food, but also because this permits of a much more free 

 distribution of their eggs. 



Thus is the case cited: "Shortly after the 10th of July, 

 coincident with the cutting of the alfalfa, the bugs were no- 

 ticed on the fruit of these (peach) trees, which was just be-
