Methods and techniques used in the development of an expert system for insect sampling plan design
(Lincoln University, 1990)
An expert systems prototype for insect sampling plan design in the New Zealand apple orchard environment was developed. The prototype advises on the preliminary design, analysis of the preliminary data and the main sampling ...
A study of insect pests of brussels sprouts in Canterbury; their phenology and the resultant crop losses
(Lincoln College, University of Canterbury, 1982)
The relationships between insect pests and damage in Brussels sprouts were studied for three seasons in Canterbury. Each season the major pest species, white butterfly (Artogeia rapae L.), diamondback moth (Plutella ...
Plant parasitic nematodes: the effect of lolines.
(Lincoln University, 2008)
Grass endophytes live their entire life cycle within the aerial portion of the grass host,
with which they form a defensive mutualism. The endophyte which resides
intercellularly within the grass, synthesizes an array ...
Role of mycorrhizae in rhizosphere processes and phosphorus dynamics
(Lincoln University, 2010-01)
The increased soil organic phosphorus (P) mineralization observed under trees compared to pasture has been attributed to the contrasting mycorrhizal associations of the two systems but to date, little work has been conducted ...
Enhancement of the efficacy of the parasitoid, Microctonus hyperodae Loan (Hymenoptera: Braconidae) by provision of floral resources to improve biological control of its host, the Argentine stem weevil (Listronotus bonariensis) (Kuschel) (Coleoptera: Curculionidae)
(Lincoln University, 2005)
In this study, conservation biological control principles were applied to increase the efficacy of Microctonus hyperodae Loan (Hymenoptera: Braconidae), a parasitoid of the Argentine stem weevil (Listronotus bonariensis ...
The fractionation and analysis of lupin seed proteins with a detailed investigation of the albumins
(Lincoln College, University of Canterbury, 1982)
Seed proteins from Lupinus angustifolius cv Uniharvest were fractionated by a modified Osborne method into four solubility classes namely, albumin, globulin, prolamin and glutelin fractions. Protein content and amino acid ...
Studies of Alfalfa mosaic virus in subterranean clover red leaf virus
(Lincoln College, University of Canterbury, 1978)
AMV was shown to be transmitted by sap, aphids and through lucerne seed but not by Cuscuta. Virus source and test plant influenced transmission frequency. Sap-inoculation tests showed that twenty species of plants were ...
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 ...
