Although various tachinid and braconid parasitoids were imported from Australia (1934 to 1973), no agents were actually released until 1974. Pest managers should learn how management methods such as conserving natural enemies and planting resistant species can help control these pests, which include leaf-feeding beetles (tortoise beetles), eucalyptus gall wasps, and at … (Chrysomelidae, Coleoptera), with particular reference to the species introduced into New Zealand. Eucalyptus are important to New Zealand’s forestry industry, providing pulp and timber, veneer lumber, farm forestry, honey production, firewood and carbon sequestration. Adult body length is about 10mm. Since this importation, biological control of P. charybdis by E. nassaui has been significantly disrupted through the arrival of an obligate hyperparasitoid, Baeoanusia albifunicle (Encyrtidae) in 2001 to New Zealand (Tribe, 2000; Murphy, 2002; Jones and Withers, 2003).

Tweet; Description: Larvae about 5mm long with broad shiny head and pro-thoracic segment. It is important to distinguish between the two because ladybirds are beneficial insects size ranges from about 4 mm to 15 mm long, Many species are metallic, pink, yellow, beige or red, Some adults have finely patterned elytra (wing covers); some of these are strongly patterned with red and black, Larvae have well developed dark heads and three pairs of legs, most are pale, some with dark stripes along the body, Larvae feed on the soft, young growth in the crowns, giving a characteristic 'broom top' appearance. Due to the absence of predators, this beetle can thrive and produce large populations that result in severe defoliation of some of the eucalypt species that we have under research. Scion is the leading provider of forest-related knowledge in New Zealand Formerly known as the Forest Research Institute, Scion has been a leader in research relating to forest health for over 50 years. Paropsis atomaria Olivier. Variation between Eucalyptus species in palatability to P. charybdis is well recognised and the planting of less palatable species such as Eucalyptus fastigata, Eucalyptus delegatensis and Eucalyptus regnans is recommended for silviculture (Styles, 1970; Bain, 1977; Wilcox, 1980).
