Are they easy to control?
Prevention of Brown marmorated stink bug entering Australia is highly important as once a Brown marmorated stink bug population has been established they are very difficult to remove or control. Initial control methods used in the USA predominantly relied on broad spectrum insecticides; however, this practices displaces standard pest management programs and can cause the outbreak of secondary pests, such as the European red mite (Panonychus ulmi), wooly apple aphid (Eriosoma lanigerum; Figure 9) and San Jose scale (Quadraspidiotus perniciosus), that are traditionally managed by natural enemies (Leskey et al. 2012).
Ultimately biological control and ultilisation of natural enemies may provide the most promising long-term solution for Brown marmorated stink bug population control in the USA (Leskey et al. 2012). Possible future biological control methods may include several species of parasoid wasp (Trissolcus species) and tachinid flies from Asia that parasitize Brown marmorated stink bug eggs and adults, respectively. In the USA, several indigenous wasp species (Trissolcus spp., Telenomus podisi), tachinid flies and various invertebrate, and vertebrate predators have been observed attacking Brown marmorated stink bug.
