  Lyriomyza spp.). Mode of action Adult female parasitic wasps of Diglyphus isaea kill second and third instar leaf miner larvae in the mine and lay their eggs [...] outside the leaf miner), using the dead larvae as food. Adult females also kill young leaf miner larvae by using them as a food source. This is known as

• Orius laevigatus

  nymphs kill approximately 54 second instar Frankliniella occidentalis nymphs during their development (four per day on average). Adult females can kill up

• Parasitic wasps

  These parasitic wasp larvae then develop inside the host insect, eventually killing it. These wasps are highly specialized, with different species targeting [...] it emerges from the host's body or the cocoon. The host pest is typically killed in the process. Host feeding In addition to parasitization, some parasitic

Here's how they work: Seeking out hosts: Entomopathogenic [...] Bacterial infection: The bacteria secret toxins and antimicrobial compounds that kill the host insect within a few days. The host becomes immobile and eventually
