Broadleaf privet, Ligustrum lucidum Aiton (Oleaceae), a late-season host for Nezara viridula (L.), Plautia affinis Dallas and Glaucias amyoti (Dallas) (Hemiptera: Pentatomidae) in northern New South Wales, Australia.
The seasonal abundances of the pentatomids Nezara viridula, Plautia affinis and Glaucias amyoti were monitored on the introduced weed, broadleaf privet (Ligustrum lucidum) from January 1998 to July 2000 at Moree, New South Wales, Australia. All developmental stages (eggs, nymphal instars and adults) of N. viridula, P. affinis and G. amyoti were recovered from privet. For all species, adult and nymphal densities peaked from February to May, coincident with privet fruiting. Nymphs of each species successfully developed when fed with L. lucidum berries in the laboratory. The importance of L. lucidum as a host is discussed in relation to its role in maintaining populations of pentatomid pest species and in particular as a late-season host prior to overwintering.
