Laboratory Nontarget Host Range of the Introduced Parasitoids Microctonus aethiopoides and M. hyperodae (Hymenoptera: Braconidae) Compared with Field Parasitism in New Zealand
Laboratory host specificity of 2 biological control agents, already introduced in New Zealand, was compared with actual field parasitism. The parasitoids were Microctonus aethiopoides Loan and… Expand
Seasonal biology and ecology in New Zealand of Microctonus aethiopoides (Hymenoptera: Braconidae), a parasitoid of Sitona spp. (Coleoptera: Curculionidae), with special emphasis on atypical behaviour.
(1) Laboratory studies on Microctonus aethiopoides, a parasitoid of Sitona discoideus, established that the development temperature thresholds of its egg and larval stages combined and pupal stage… Expand
Systematic mass rearing and release ofMicroctonus hyperodae (Hym.: Braconidae, Euphorinae), a parasitoid of the argentine stem weevilListronotus bonariensis (Col.: Curculionidae) and records of its…
The method whereby equal numbers of seven ecotypes of the parasitoidMicroctonus hyperodae Loan (Hymenoptera: Braconidae, Euphorinae) were reared and released is described along with the reasons for… Expand
Importation and quarantine of Microctonus hyperodae, a South American parasitoid of Argentine stem weevil.
Host specificity testing and suitability of the parasitoidMicroctonus hyperodae (Hym.: Braconidae, Euphorinae) as a biological control agent ofListronotus bonariensis (Col.: Curculionidae) in New…
AbstractThe behaviour of the parasitoidMicroctonus hyperodae Loan was studied under quarantine conditions to determine its likely host range in New Zealand. The species was imported from South… Expand
Isolate-dependent impacts of fungal endophytes in a multitrophic interaction
Neotyphodium lolii, an endophytic fungus of perennial ryegrass, deters Argentine stem weevil, Listronotus bonariensis, an important insect pest of pastures in New Zealand. Deterrence is apparently… Expand
Transportation of nonindigenous species via soil on international aircraft passengers’ footwear
The potential for transported soil to harbour and spread nonindigenous species (NIS) is widely recognised and many National Plant Protection Organisations (NPPOs) restrict or prohibit its movement.… Expand
East meets west: adaptive evolution of an insect introduced for biological control.
1. A possible explanation for low success rates when introducing natural enemies to new regions for biological control of insect pests is that they fail to adapt to their new conditions. Therefore it… Expand
Collections of Microctonus aethiopoides Loan (Hymenoptera: Braconidae) from Ireland
The biological control programme against Sitona lepidus (Gyllenhal) (Coleoptera: Braconidae) commenced in 1998, with the first parasitised weevils imported into New Zealand quarantine in 2000.… Expand
Clover root weevil in the South Island: detection, response and current distribution
Sitona lepidus had spread throughout the North Island of New Zealand by 2005, and was first detected in the South Island in January 2006 when one individual was found at Harewood, Christchurch.… Expand
