Tetrastichus planipennisi is a parasitoid of the emerald ash borer, a wood boring insect native to Asia which is an invasive species in North America.
T. setifer is a paraditoid of the scarlet lily beetle. The beetle is invasive in North America, and highly destructive to lily species; the wasp has been introduced there for biological pest control.[1][2]
T. planipennisi is being evaluated as a biological control agent.
Host species
The genus Tetrastichus parasitizes many different species of Lepidoptera, such as Pyralis farinalis.[3]
