Kurdjumov, 1912
Species Guides
4Neochrysocharis is a of small in the Eulophidae. in this genus are endoparasitoids of leafmining insects, particularly agromyzid flies. Some species exhibit -feeding and possess both thelytokous () and arrhenotokous (sexual) reproductive strains. Multiple species have been evaluated as agents for leafminer pests in agricultural systems.

Habitat
Vegetable agroecosystems; associated with supporting leafmining insects
Distribution
China; Indonesia; Vietnam; Southeast Asia; Argentina; India (Madhya Pradesh); United States (California, Florida); Canary Islands; Beijing
Diet
-feeding ; parasitizes and feeds on larval stages of leafmining insects
Host Associations
- Agromyzidae - primary leafmining flies
- Liriomyza - leafminer including L. chinensis, L. trifolii
- Liriomyza trifolii - American serpentine leafminer
- Tuta absoluta - South American tomato leafminer, tomato (Lepidoptera: Gelechiidae)
- Letana - Orthoptera: Tettigoniidae; record from India
Life Cycle
Larval endoparasitoid; development occurs inside larvae
Behavior
-killing include , host-feeding, and host-stinging; can directly parasitize and feed on 1st-3rd instar host larvae but kills 4th instar larvae only by host-stinging without successful development; exhibits host searching and oviposition behaviors affected by exposure
Ecological Role
agent for leafminer pests; natural enemy in programs for vegetables and tomato crops
Human Relevance
Evaluated and mass-reared as agent for agricultural pests including Tuta absoluta and Liriomyza leafminers; thelytokous strains show greater biocontrol potential than arrhenotokous strains with higher and -killing rates; sensitivity to certain (imidacloprid and ethofenprox highly toxic; pymetrozine harmless) affects integration into programs
