| In spite of generally high hyperparasitism, no detrimental effect on the control efficiency of either primary parasitoid was noticed. |
| Simple laboratory tests can determine whether larval competition or hyperparasitism occurs among parasitoid species targeted for biological control. |
| However, this study suggests that C. concinnata in Virginia may not escape hyperparasitism very effectively. |
| In that case, limiting hyperparasitism would be more important for successful biological control of aphids. |
| Hyperparasitism by Trichothecium roseum results in a pink or white coloration of the knots. |
| Hyperparasitism the parasitic habit of one species upon another parasitic species has also attracted attention. |
