Summary

Encarsia is a diverse genus of minute parasitic wasps in the family Aphelinidae, known for their role as biocontrol agents, primarily targeting whiteflies and scale insects. With around 400 described species, the genus is complex, with many species yet to be fully described, and exhibits high host specificity, making them effective bio-control agents.

Physical Characteristics

Adults are tiny insects about 1 to 2 millimeters in size.

Identification Tips

Morphological classification is complex due to inter- and intra-specific variations.

Habitat

Found in various habitats where their host insects are present, particularly in horticultural and agricultural settings.

Distribution

Globally distributed, with approximately 400 described species and many more expected to be undiscovered.

Diet

Primarily parasitoids of whiteflies (Aleyrodidae) and scale insects (Diaspididae). Some species also attack other insects, such as aphids, lepidopteran eggs, and shield-back bugs (Plataspidae).

Life Cycle

Females mostly develop as primary endoparasitoids, while males frequently act as hyperparasitoids.

Reproduction

Heteronomous relationships exist, where females and males have different interactions with host species.

Ecosystem Role

Significant role in biological pest control, especially in horticulture and intensive agriculture.

Economic Impact

Invaluable for biological pest control in crops, particularly those grown under glass.
