Host Associations
- Coccoidea - primary group, scale insects
- Hemiptera - broader range within true bugs
Ecological Role
As of scale insects and other Hemiptera, Tetracneminae plays a significant role in regulating of these plant-feeding insects. This makes them important natural enemies in agricultural and forest , particularly in contexts where scale insects reach pest status.
Human Relevance
Tetracneminae have been utilized in programs against scale insects. Their effectiveness in suppressing reduces reliance on chemical in systems.
