Cross-Attraction of Nezara viridula (Linnaeus) and N. antennata Scott (Heteroptera: Pentatomidae) to Male-Produced Pheromones

Abstract

We investigated the attractiveness of adult males of the southern green stink bug, Nezara viridula (Linnaeus) and the oriental green stink bug, N. antennata Scott in the field in Fukuoka Prefecture in 2008 and 2009. In traps baited with males of N. viridula, adult males and females of N. antennata in addition to adults of N. viridula were captured. Similarly, in traps baited with males of N. antennata, adult males and females of N. viridula in addition to adults of N. antennata were captured. These results indicate that adult males of N. viridula and N. antennata emit pheromones and attract not only conspecifics but also individuals of other species.
