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 ...
Applied ecology of the Tasmanian lacewing Micromus tasmaniae Walker (Neuroptera : Hemerodiidae)
(Lincoln College, University of Canterbury, 1989)
The Tasmanian lacewing (Micromus tasmaniae Walker) is one of the most common aphid predators occurring in lucerne crops in New Zealand. A comparison of sampling techniques, and the output from a simulation model, suggest ...
Competition between strains of Rhizobium meliloti (Dangeard) for nodulation of lucerne
(Lincoln University, 1990)
In order to ensure that strains of rhizobia that are efficient nitrogen fixers nodulate cultivated legumes in the field, it is important to be able to identify those that can compete effectively with indigenous strains in ...
Biology and predation of Pacific damsel bug, Nabis kinbergii Reuter, (Hemiptera: Nabidae)
(Lincoln College, University of Canterbury, 1985)
This study investigated the role of a polyphagous insect predator, the Pacific damsel bug (PDB), Nabis kinbergii Reuter [Hemiptera: Nabidae], in the regulation of the Australian crop mirid (ACM), Sidnia kinbergi (Stal)[Hemiptera ...
Study on the growth, persistence and interaction between Corynebacterium insidiosum (McCullock) Jensen and Rhizobium meliloti Dang. in soil, and in the infection of Medicago sativa L.
(Lincoln College, University of Canterbury, 1980)
Growth and persistence of C. insidiosum and R. meliloti in soil and rhizosphere, and their interactions with F. oxysporum and V. alboatrum in the infection and nodulation of lucerne plants were investigated. The droplet ...
The reproductive seasonality and flight capability of Sitona discoideus Gyllenhal (Coleoptera: Curculionidae) and its pattern of larval establishment in Canterbury lucerne
(Lincoln College, University of Canterbury, 1987)
In order to improve the level of understanding of the reproductive seasonality and flight potential of Silona discoideus Gyllenhal, samples were taken at regular intervals from lucerne (Medicago saliva L.) stands throughout ...
