Halticoptera
Spinola, 1811
Halticoptera is a of chalcid wasps in the Pteromalidae. in this genus are koinobiont endoparasitoids of agromyzid leafminer flies (Diptera: Agromyzidae). They have been investigated as agents for leafminer pests, though suitability varies significantly between and host species.

Distribution
Japan; Iran; United Kingdom; United States (Alabama, California, Colorado); China (Beijing); Canary Islands.
Host Associations
- Liriomyza trifolii - Unsuitable ; and larvae encapsulated by host haemocytes, preventing development
- Liriomyza chinensis - Suitable ; and larvae develop successfully
- Chromatomyia horticola - Suitable ; and larvae develop successfully
- Liriomyza huidobrensis - for H. arduine
Life Cycle
Koinobiont development: and larvae develop within living . In suitable hosts, development proceeds to ; in unsuitable hosts, developmental stages are encapsulated by host haemocytes and fail to complete development.
Behavior
Koinobiont lifestyle: parasitoid larvae develop within a that continues to feed and grow. Some exhibit by host immune in certain host species, preventing successful .
Ecological Role
of leafminer flies; potential agent for leafminer . Effectiveness limited against some leafminers due to immune .
Human Relevance
Investigated for of agricultural leafminer pests. H. circulus shows promise for controlling leafminers Liriomyza chinensis and Chromatomyia horticola, but is ineffective against the Liriomyza trifolii in Japan due to response.
