Abundance, activity and distribution of soil-surface arthropod predators in arable farmland
(Lincoln University, 1997)
Intensive agricultural techniques, such as the high input of pesticides has caused increasing pest problems in arable agroecosystems. In New Zealand, biodiversity and sustainability in agroecosystems have become important ...
'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 impact of selective beech (Nothofagus spp.) harvest on litter-dwelling invertebrates and the process of litter decomposition
(Lincoln University, 1999)
Minimising the potential impact of forest management requires an understanding of the key elements that maintain forest diversity and its role in ecological processes. Invertebrates are the most diverse of all biota and ...
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: ...
The reproductive seasonality and morphology of Argentine stem weevil Hyperodes bonariensis Kuschel (Coleoptera: Curculionidae) and the effect of host grasses on its pre-reproductive development
(Lincoln College, University of Canterbury, 1979)
In order to improve understanding of the phenology of Argentine stem weevil (Hyperodes bonariensis Kuschel), samples were collected at regular intervals from the field and the changes in their reproductive morphology ...
Metabolism of triacylglycerol-rich lipoproteins in sheep
(Lincoln University, 1991)
This thesis describes two approaches for studying of lipoprotein metabolism in sheep. The first approach involves the assay of lipoprotein lipase (LPL) activity to determine the role of lipoprotein-triacylglycerol fatty ...
Population dynamics and pest assessment studies of grass grub (Costelytra zealandica (White), Melolonthinae) in the North Island of New Zealand
(Lincoln College, University of Canterbury, 1975)
Studies of the common grass grub (Costelytra zealandica (White)) covered two major aspects, population ecology and pest assessment. The object or these studies was to investigate the feasibility of developing models, ...
Biology and control of green vegetable bug, Nezara viridula (L.) (Heteroptera: Pentatomidae) in process sweet corn, Zea mays (L.) in the East Cape Region, New Zealand
(Lincoln University, 1999)
Nezara viridula (L.) (Heteroptera: Pentatomidae), the green vegetable bug (GVB) is a serious pest of process sweet corn Zea mays (L.) in the East Cape region of the North Island, New Zealand. In the past seven years the ...
Effect of temperature on development of Listronotus bonariensis (Kuschel) (Coleoptera: Curculionidae) on Lolium perenne (L.) (Gramineae: Festucoidae)
(Lincoln University, 1999)
Argentine stem weevil (ASW) Listronotus bonariensis (Kuschel) is an introduced species that attacks improved graminaceous pasture and crop throughout much of New Zealand. It is recognised as the most important arthropod ...
Nitrogen nutrition of mycorrhizal pines
(Lincoln College, University of Canterbury, 1972)
Nitrogen has been central to many of these speculations regarding the function of mycorrhizas in tree nutrition and growth. Historically it was felt that mycorrhizas were more efficient in absorbing nitrogen from humus ...
