Pheromone strains of the Cosmopolitan pest, <i>Nezara viridula</i> (heteroptera: Pentatomidae)

Abstract

Abstract Sexually mature males of the sourthern green stink bug, N. viridula , release a pheromone attractive in the field to conspecific females, males, and late‐stage larvae and to the parasitoid Trichopoda pennipes (Diptera: Tachinidae). The pheromone blend typically includes ( Z )‐α‐bisabolene (17%), trans‐ and cis ‐1,2‐epoxides of ( Z )‐α‐bisabolene (44 and 15%, respectively), ( E )‐nerolidol (1.4%), and n ‐nonadecane (7.4%). The existence of Nezara pheromone strains, first suggested by differential Trichopoda parasitization of geographically isolated N. viridula populations, has been chemically verified.
