T. japonicum can be found naturally in rice ecosystems, but are dispersed commercially to many monocultures as a biological control.

[7] T. japonicum relies on long-range chemical emissions from damaged plants in order to locate hosts.

Lepidoptera can leave behind female wing scales, larva saliva, footprints, and egg wash which will act like kairomones and attract the parasitoid.

[6] In order for this species to be a successful biological control, the wasps need to have time-specific multiple releases.

T. japonicum as a biological could greatly improve natural enemy populations, which will help prolong the effects of pest control.

[10] The use of these wasps will also help protect the ecological environment, reduce pollination of fields, and ensure safe agricultural products.

[4][2] One study found that the highest mortality rate in T. japonicum is observed when acephate, an organophosphate, is used as a treatment.
