bug, is described in Entomology Bulletin No. 64, part I, 1911, 

 and their habits were discussed andj better means of control 

 than given by the Bureau were pointed out by me on pages 

 1 to 16 of my Circular No. 140, 1914. 



Of the two pests the grain bug was the first to come to 

 notice with a record of having destroyed in 1895 40 acres of 

 peas and two acres of lima beans in Reeves County, Tex. 

 (Ent. Bull. 65, p. 2), but subsequently the conchuela attracted 

 the more attention of the two. The grairi bug has recently 

 been described in U. S. D. A. Bulletin No. 779. 



In making tests to control the conchuela Dr. A. W. Mor- 

 rill, the agent of the Bureau of Entomology making the tests, 

 also incidentally made use of a gasoline torch. After saying 

 that the bugs had in a certain test case in Mexico, for the time 

 being congregated in a vineyard of about 10 acres, and that 

 each cluster of grapes was attacked by several bugs, and that 

 the maximum number noted on a single cluster was 25, he says 

 the grapes were picked by the owner without consultation with 

 him. "This step was, however, inadvisable, since the fruit, 

 which was of comparatively small value, would have served 

 as a trap at which the bugs could have been easily destroyed 

 when so thickly concentrated. As it was, the bugs gathered 

 in groups of hundreds on the trellis posts and on the vines, 

 principally at the forks, where they were destroyed partly by 

 spraying and partly by the use of a gasoline blast-torch. The 

 last mentioned method, while effective in its destruction of the 

 pest, injured the vines to a certain extent in nearly all cases.'*
