Peristenus pseudopallipes is a parasitoid, which lives within a host as part of its life cycle.
[1] P. pseudopallipes has cytochrome C oxidase, a key component in the respiratory chain reaction for the reduction of oxygen into water.
[3] P. pseudopallipes infects the nymphal stage of Lygus lineolaris between the end of July and the beginning of August.
[5] Host L. lineolaris feeds on over 300 plant species and causes at least two billion dollars in losses per year.
Because P. pseudopallipes and other genus members cause host death shortly after hatching, introducing Peristenus spp.
