Host-range testing, introduction, and establishment of Cydia succedana (Lepidoptera: Tortricidae) for biological control of gorse, Ulex europaeus L., in New Zealand

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

Classical biological control is being attempted for Paropsis charybdis (Coleoptera Chrysomelidae Chrysomelinae) an Australian eucalypt pest established in New Zealand The Australian solitary larval endoparasitoid Eadya paropsidis (Hymenoptera Braconidae) is under investigation Leaffeeding larvae of closelyrelated chrysomelid nontarget species for host range testing were examined against E paropsidis using various assays Detailed behavioural observations of E paropsidis were undertaken during 1) Nochoice sequential assays of the AB alternating with BA type (where A is the target P charybdis and B is the nontarget species); and 2) Twochoice assays of the AB type 3) In addition groups of nontarget larvae were exposed to E paropsidis under nochoice conditions for 24 hours then reared for survival to ascertain the physiological development of any parasitoid lifestages In all cases survival and development parameters of nontargets species were compared to the target P charybdis

Classical biological control is being attempted for Uraba lugens (Lepidoptera Noctuidae Nolinae) an Australian eucalypt pest established in New Zealand The Australian solitary larval endoparasitoid Cotesia urabae (Hymenoptera Braconidae) is the most promising agent under investigation A nontarget species list was compiled for host range testing The endemic species Celama parvitis is the sole New Zealand representative of the Nolinae and was highest priority The next most closely related subfamily is the Arctiinae of which New Zealand has four endemic species (Metacrias huttoni M erichrysa M strategica and Nyctemera annulata) and one introduced biological control agent (Tyria jacobaeae) The merits of including other more distantly related members of the Noctuidae and unrelated Lepidoptera filling a similar niche are discussed

Range Testing

The accuracy of host range testing in weed biocontrol programmes using plant pathogens has been questioned prompting a research programme into the field safety record of pathogens used for weed biocontrol in New Zealand Nationwide disease surveys were conducted from 20002009 and focused on species closely related to target weeds and therefore potentially most at risk of attack These surveys identified pathogens associated with any disease symptoms observed on nontarget hosts Disease damage attributable to biocontrol agents was observed on two nontarget plants Pustules of the blackberry rust Phragmidium violaceum were found on the endemic Rubus species R cissoides (bush lawyer tataramoa) at one location This result was predicted from host range safety tests conducted prior to its arrival in New Zealand No nontarget damage was observed in the remaining case studies confirming to date that all biocontrol pathogens are highly host specific to their target weeds
