'Attract and reward' : combining a floral resource subsidy with a herbivore-induced plant volatile to enhance conservation biological control
(Lincoln University, 2009)
Experiments were conducted to assess whether a concept termed 'attract and reward' (A&R) could enhance conservation biological control (CBC). In A&R, a synthetically-produced herbivore induced plant volatile (HIPV) ('attract') ...
The role of floral resource subsidies in structuring a four tropic-level parasitoid/host system
(Lincoln University, 2007)
In this study, conservation biological control principles were explored to determine whether the efficacy of Aphidius ervi Haliday (Hymenoptera: Braconidae), a parasitoid of the pea aphid Acyrthosiphon pisum Harris (Homoptera: ...
Testing the effect of in planta RNA silencing on Plasmodiophora brassicae infection
(Lincoln University, 2006)
In the late 1990s, a series of landmark publications described RNA interference (RNAi) and related RNA silencing phenomena in nematodes, plants and fungi. By manipulating RNA silencing, biologists have been able to create ...
A survey of coastal and marine birds at Bako National Park and Samunsam Wildlife Sanctuary, Sarawak

Biological control of onion white rot using Trichoderma harzianum
(Lincoln University, 2001)
The biological control of Sclerotium cepivorum, the causal agent of onion white rot, by Trichoderma harzianum and T. virens was studied in a glasshouse trial. T. Harzianum (isolates C52 and D73) and T. virens (isolate GV4) ...
Spider distribution in agroecosystems in Canterbury, New Zealand
(Lincoln University, 2000)
The spider assemblage from four shelterbelts and their adjacent grazed pastures in South Island, New Zealand was suction sampled from August 1994 to July 1995 and from March 1996 to March 1997. Spider density decreased ...
Relative reductions in counts of enteric bacteria and bacteriophages in surface and groundwaters
(Lincoln University, 2003)
Reductions in counts of enteric indicator bacteria and bacteriophages were compared in surface and groundwaters. In surface waters, inactivation rates were determined in sunlight-exposed and dark chambers of fresh and ...
Population ecology of the red admiral butterfly (Bassaris gonerilla) and the effects of non-target parasitism by Pteromalus puparum
(Lincoln University, 2004)
There is anecdotal evidence that populations of the New Zealand endemic red admiral butterfly Bassaris gonerilla (F.) have declined since the early 1900s. This decline has been associated with the introduction of the ...
Using DNA barcodes to investigate the taxonomy of the New Zealand sooty beech scale insect
(Science & Technical Publishing, Department of Conservation New Zealand, 2007-11)
It is currently proposed that there are two species of honeydew-producing sooty beech scale insects (Ultracoelostoma spp.) in New Zealand. It is thought that U. brittini lives exclusively on trunks of southern beech (Nothofagus ...
Deciduousness in the New Zealand flora: Modelling the consequences of winter leaf loss for annual canopy carbon uptake
(Lincoln University, 2002)
This thesis investigates aspects of deciduousness in the native New Zealand tree flora by modelling the consequences of winter leaf loss on annual carbon uptake for two co-occurring tree species with contrasting leaf habit; ...
