Telenomus dalmanni

Taxonomic position
Telenomus dalmanni belongs to the order Hymenoptera and the family Scelionidae. These insects are classified as egg parasitoids, which are highly specialized parasitoids that complete their entire larval development within the eggs of other arthropods, primarily moths and butterflies.

Biology and life cycle
The life cycle of this species is perfectly synchronized with its hosts. The adult female locates a host egg and inserts her own egg inside it. The larva of the parasitoid consumes the internal contents of the host egg, effectively killing the embryo of the pest. The pupation occurs inside the host's egg shell, followed by the emergence of the adult wasp.

Crops affected
This species interacts with various pests that threaten cereal, vegetable, and orchard crops. By parasitizing the eggs of lepidopteran pests, it acts as a significant natural regulator of pest populations in agricultural landscapes across its geographic range.

Damage and economic significance
The insect itself does not feed on plant tissue, and therefore does not cause direct crop loss. Its importance is primarily ecological and economic, as it serves as a natural enemy that prevents outbreaks of major agricultural pests. Monitoring their presence is essential for successful biological control programs.

Control measures

• Implementation of Integrated Pest Management (IPM) strategies.
• Selective use of insecticides to avoid harming parasitoid populations.
• Preservation of natural habitats and hedgerows to support beneficial insect populations.
• Regular field scouting to monitor pest egg density and parasitism rates.
