The gum leaf skeletoniser (Uraba lugens) a significant pest in Australia is now well established on Eucalyptus spp in the Auckland region One larval parasitoid (Meteorus pulchricornis) and two pupal parasitoids (Xanthopimpla rhopaloceros and Anacis sp) were recorded from U lugens collected in southwest Auckland Parasitism of M pulchricornis and X rhopaloceros against U lugens and other hosts in New Zealand (Helicoverpa armigera and Epiphyas postvittana respectively) was compared using nochoice and choice tests under controlled conditions Uraba lugens is a suitable host for development of both M pulchricornis and X rhopaloceros Choice tests revealed that M pulchricornis prefers H armigera larvae to U lugens Attack by X rhopaloceros occurred only when host pupae were presented within their cocoons Meteorus pulchricornis may compete with proposed classical biological control agents introduced against U lugens while X rhopaloceros is more likely to complement them

Over Time

Lygodium microphyllum (Lygodiaceae) is an invasive climbing fern in peninsular Florida. Two classical biological control agents are currently being released against L. microphyllum: a leaf galling mite, Floracarus perrepae (Acariformes: Eriophyidae), and a moth, Neomusotima conspurcatalis (Lepidoptera: Crambidae). Little is known about how the two species interact in the field; thus we conducted oviposition choice tests to determine the effects of F. perrepae presence on oviposition behavior in N. conspurcatalis. Further, we conducted feeding trials with N. conspurcatalis larvae to establish the effects of gall presence on larval survival and rate of development, and determine whether N. conspurcatalis larvae would directly consume F. perrepae galls. Neomusotima conspurcatalis laid significantly more eggs on mite galled (52.66 ± 6.211) versus ungalled (34.40 ± 5.587) L. microphyllum foliage. Feeding trials revealed higher mortality in N. conspurcatalis larvae raised on galled (60%) versus ungalled (36%) L. microphyllum material. In gall feeding trials, N. conspurcatalis larvae consumed or damaged 13.52% of galls, and the rate of direct gall feeding increased over time as leaf resources were depleted. Our results suggest that, where N. conspurcatalis and F. perrepae co-occur, competitive interactions could be more frequent than previously anticipated; however, we do not expect these antagonistic interactions to affect the establishment of either agent.

Biocontrol Potential

Globally the thistle tribe Cardueae (Asteraceae) contains approximately 2500 species of which at least 339 have weed status In New Zealand 63 of these are present but only nine are recognised problems with the remainder being potential threats or quot;sleeper weedsquot; To evaluate these potential threats the 339 global thistle weeds were ranked from most to least important based on an assigned Index of Weed Importance and grouped into five weed importance categories Extreme High Moderate Low and Minor Of the global species in these categories 94 56 28 19 and 7 respectively are present in New Zealand and mitigating the most serious potential threats would be prudent An option is the novel use of classical biological control agents that specialise on the thistle tribe rather than specific target species This is feasible for New Zealand because in the tribe Cardueae there are no natives and few economicallyvalued exotic species

Research Questions

Conservation biological control (CBC) enhances biological control efficacy by providing pollen nectar shelter and/or alternative prey to biological control agents It is a fastgrowing subdiscipline of biological control with notable recent successes In contrast classical biological control in spite of its long history has not risen above a 10 success rate since 1880 and can have muchpublicised negative consequences This paper presents recent data on CBC research in brassicas in New Zealand and discusses how understanding and effectiveness can be improved The provision of floral nectar to parasitoids such as Diadegma can enhance longevity from two days in the presence of water only to 30 days and can lead to higher fecundity The paper outlines key research questions for the future

In the late 1970s, Brazilian peppertree, Schinus terebinthifolia Raddi (Sapindales: Anacardiaceae), was targeted for classical biological control in Florida because its invasive properties (see Host Plants) are consistent with escape from natural enemies (Williams 1954), and there are no native Schinus spp. in North America. The lack of native close relatives should minimize the risk of damage to non-target plants from introduced biological control agents (Pemberton 2000). [...]

Classical biological control is proposed for Paropsis charybdis (Coleoptera Chrysomelidae Chrysomelinae) a eucalypt pest established in New Zealand The Australian solitary larval endoparasitoid Eadya paropsidis (Hymenoptera Braconidae) is under investigation A potential nontarget species list was compiled for host range testing There are no endemic species of paropsines in the New Zealand fauna only invasive pest beetles The most closely related endemic beetles to the paropsines are Chrysomelinae in the genera Allocharis Aphilon Caccomolpus Chalcolampra and Cyrtonogetus Little is known about these species New Zealand has also introduced 12 beneficial chrysomelid weed biological control agents which include Chrysomelinae and their sister group the Galerucinae One endemic beetle six beneficial beetles and two pest beetles are listed as the highest priority species for host specificity testing
