These wasps are vital for the biological control of herbivorous insect populations through a top-down approach. Here, we examine the complex ways in which pesticides may compromise the parasitoids’ life history traits, interfere with their host-seeking behaviour, and modulate the immune responses of the hosts that in turn affect parasitoid success.

The sesquiterpenoid hormones and their synthetic mimics are agonist ligands of a unique JH receptor (JHR) protein, methoprene-tolerant (MET). Upon binding an agonist to its PAS-B cavity, MET dissociates from a cytoplasmic chaperone complex including HSP83 and concomitantly switches to a bHLH-PAS partner taiman, forming a nuclear, transcriptionally active JHR heterodimer. This course of events resembles the vertebrate aryl hydrocarbon receptor (AHR), activated by a plethora of endogenous and synthetic compounds. Like in AHR, the pliable PAS-B cavity of MET adjusts to diverse ligands and binds them through similar mechanisms.
