Popis:	A stilt-bug, Jalysus Spinosus Say is recorded as a serious pest of the tomato in Missouri. It is distributed from Maine to the Rocky Mountains and commonly occurs on the undergrowth of oak woods. It causes the blossoms to wither up and drop off, preventing the plants from setting fruit. The life-cycle, appearance, nature of injury, and control measures are briefly discussed. This insect was first recorded as an enemy of the tomato in Missouri, several years ago. Its depredations have apparently not been as severe or its work may have been attributed to other agencies during the past few seasons, for no further record of its injury appears. During the past summer, however, the writer's attention was directed to it again, by an apparent blighting of the tomato blossoms in and around Mountain Grove and in other parts of the state. There was a consequent failure in the set of fruit and upon examination, early in July, it was found that there were many stilt-bugs present and that these insects were responsible for the damage done.
