Do plants have a language that we can learn to understand?
Orius insidiosus, also called Flower Bug or Minute Pirate Bug, is a local species of the United States and Canada.

Moreover, this bug is well known for its compatibility to work with other specialist and generalist predators.
When we talk about “biocontrol,” we’re normally referring to insect biological control agents such as Encarsia formosa, Amblyseius cucumeris (now a.k.a. Neoseiulus cucumeris) or Stratiolaelaps scimitus (Hypoaspis miles, or whatever it is called this week).
