| Question: | "Under separate cover I am sending a sample of Kentucky bluegrass collected late in December. I will appreciate your identifying the insects that have been depositing their eggs on the grass blades. Many of the eggs hatched within 3 days after the sample was taken. The blades bearing egg deposits eventually die." |
| Source of Question: | West Virginia |
| Answer/Response: | "An examination of these specimens revealed the fact that the bluegrass was attacked by the "green bug" Toxoptera granimum Rond. The "eggs" to which you referred are the dried and swollen bodies of the aphids in which had developed the little winged parasite, Aphidins testaceipes Cress. These had hatched out into the box after the sample had been collected. This parasite is useful in controlling the green bug. The females of the green bug are capable of reproducing at temeperatures as low as 45° F or lower and it is not unusual for them to spend the winter in the crowns of plants or in bluegrass even in Washington, so that their presence in Huntington, West Virginia, is not at all remarkable. The rusty red condition of the blades of grass was caused by the feeding of the green bug. In fact, the presence of the insect is often indicated by clumps of discolored blades such as those enclosed with the specimens." |
