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 ...
Biochemical aspects of resistance to rust by barley
(Lincoln College, University of Canterbury, 1985)
In this work the in vivo RNA synthesis in the inoculated leaves of barley Hordeum vulgare L. cvs. Kakapo, Zephyr and DSIR725-02, was investigated using the inhibitor Actinomycin-D (Act-D). The results indicated that the ...
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 ...
A study of the biology and population dynamics of Synanthedon tipuliformis (Clerck) (Lepidoptera: Sesiidae) in Canterbury, New Zealand
(Lincoln College, University of Canterbury, 1975)
The study covered the period August 1971 to February 1975 and was conducted in three blackcurrant plots. One plot comprised mature bushes that were pruned but not sprayed during the course of the study; the other two plots ...
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: ...
An experimental evaluation of resource allocation in island plants with respect to their invertebrate herbivores
(Lincoln University, 2008)
New Zealand’s isolation and periods of marine transgression have limited its biota to an
extent which can be considered depauperate, even by island standards. Endemic vertebrates
are rare and prominent invertebrate families, ...
Climate warming and disturbance influences on Nothofagus treelings in North Westland, New Zealand
(Lincoln University, 2001)
Globally, there is a great deal of concern over the impact of climate warming and other associated changes in climate. Treeline forests are generally thought to be highly sensitive to changes in temperature, as they occur ...
The soil ecology of Serratia entomophila, A bacterial pathogen of the New Zealand grass grub, Costelytra zealandica (White)
(Lincoln College, University of Canterbury, 1989)
Serratia entomophila (Enterobacteriaceae) is a newly described species of bacterium, currently being developed as a biological control agent for the New Zealand grass grub Costelytra zealandica (White) (Coleoptera: ...
The comparative biology of Fluttering shearwater and Hutton's shearwater and their relationship to other shearwater species
(Lincoln College, University of Canterbury, 1985)
The discovery and taxonomic history of fluttering shearwater (Puffinus gavia (Forster) and Hutton's shearwater (Puffinus huttoni Mathews) are reviewed. Taxonomic theory, where appropriate to this thesis, is discussed. The ...
Understorey management for the enhancement of populations of a leafroller (Lepidoptera: Tortricidae) parasitoid (Dolichogenidea tasmanica (Cameron)) in Canterbury, New Zealand apple orchards
(Lincoln University, 1999)
This study investigated understorey management in Canterbury, New Zealand, apple
orchards for the enhancement of populations of Dolichogenidea tasmanica (Cameron)
(Braconidae) for leafroller (Lepidoptera: Tortricidae) ...
