Figitid wasps
The family Figitidae belongs to the order Hymenoptera. This is a large group of small parasitic wasps, which are mainly entomophagous, although individual representatives may exhibit specific characteristics that affect the state of agricultural ecosystems.

Figitid wasps
In the context of agronomy, it is important to understand that figitids primarily parasitize the larvae of dipterans, including groups such as fruit flies (Drosophilidae) and some species of leaf-mining flies. Therefore, their status as a "pest" is often debated, as they more frequently act as regulators of other insect populations, though their presence may be associated with damage to plant tissues during oviposition.
The biology of the family is characterized by a complex development cycle, including the egg, larval, pupal, and adult stages. Females lay their eggs directly inside the host's body or in its habitat. The development of the larva occurs within the host organism, leading to its death, which makes them important objects of study within biological pest control programs.
The nature of the damage attributed to these insects most often consists of micro-injuries to plant tissues in areas where they search for hosts or lay eggs. The harm manifests as a weakening of plant immunity or the transmission of pathogenic microorganisms through punctures, which indirectly reduces the overall productivity of crops.
To protect plants from the negative impact of figitids, a comprehensive approach is recommended. The main measures include
- crop rotation,
- destruction of weed reservoirs,
- monitoring insect populations using pheromone traps,
- application of selective insecticides when the economic threshold is exceeded.
