Lonicera japonica is a host plant for Helicoverpa zea
It has been observed in southwestern Georgia and northern Florida (US) that flowers of Lonicera japonica could support populations of Heliothis virescens and Helicoverpa zea (EPPO A1 quarantine pest). Studies conducted at different sites indicate that wild L. japonica is an important early and late-season host for H. virescens and H. zea in southern Georgia and northern Florida. This is the first record of L. japonica as a host plant for Heliothis virescens and Helicoverpa zea.
