Tetrastichus planipennisi is a parasitic non-stinging wasp of the family
Life cycle
Tetrastichus planipennisi parasitize EAB larvae by drilling through the bark and laying eggs on its host. The hatching parasitoid larvae feed and develop on the EAB larva, resulting in its death. Tetrastichus completes at least four generations each year and one EAB larva can produce up to 127 Tetrastichus adults. Tetrastichus planipennisi survive the winter as larvae inside their host or host gallery under the bark of ash trees.[2]
Biological control
Tetrastichus planipennisi, a gregarious larval endoparasitoid, has been introduced and released into the
Research on the viability of as an effective biocontrol agent is ongoing in the US and Canada. Laboratory methods have been developed for continuous rearing of this and other species of EAB parasitoid wasps. Extensive studies on the specificity of these parasitoids on native beetles and other insects has revealed that in laboratory no-choice assays, Tetrastichus attacked only actively feeding EAB larvae in ash branches and rejected all non-EAB species as hosts.[4]
