Pecan South. 55/24-30. Interpretive Summary: Technical Abstract: The question is whether the biological control on pest species of concern occurs at levels sufficient to prevent economic damage? Here is where a scouting program will let you know, for instance, that natural enemies are no longer maintaining aphid abundance below the economic threshold and an aphicide treatment is warranted. Although each pecan pest species is subject to natural biological control, it is the pecan aphids that are most discussed as targets of natural biological control in the pecan orchard. In part, this is because the pecan aphids are susceptible to multiple species of natural enemies thus increasing the robustness of this guild for aphid management. A negative disturbance in the life cycle of one natural enemy species, for example, can be compensated for by the other natural enemy species. |
