Use of models and phenological forecasting in applied entomology
(Lincoln University, 1993)
Although experienced modellers are usually aware of the dangers and benefits of the use of models in applied entomology, many scientists who may use models are not. Some remain sceptical that models serve any useful purpose, ...
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 ...
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 ...
Some aspects of the biology, population dynamics and economic status of Wiseana cervinata (Walker) (Hepialidae: Lepidoptera)
(Lincoln College, University of Canterbury, 1973)
Entomology, like many other biological disciplines has developed into a quantitative science in nearly all aspects of the subject. Insect ecology is no exception, and in fact, has probably received more attention recently ...
The cell wall structure of Selenomonas ruminantium
(Lincoln College, University of Canterbury, 1979)
The cell wall structure of Selenomonas ruminantium subsp. lactilytica Str GA192 and subsp. ruminantium Str PC18 was examined. Whole cell walls of strain GA192 contained: - 11% total carbohydrate; 1% phosphorus; rhamnose; ...
The effect of environmental factors and crop interference on the biology of yarrow (Achillea millefolium L.) seed and seedlings
(Lincoln College, University of Canterbury, 1983)
A population of 58 seedling yarrow (Achillea millefolium) plants m⁻² produced approximately 243,000 viable seeds per square metre in the first season of growth and development. Approximately 10% of the freshly harvested ...
The effect of temperature on the biology and population ecology of Agasicles hygrophila (Coleoptera: Chrysomelidae), a biological control agent of alligator weed (Alternathera philoxeroides)
(Lincoln University, 1996)
Alligator weed, Alternanthera philoxeroides (Mart.) Griseb. (Amaranthaceae) is a perennial, stoloniferous herb which grows primarily as an emergent aquatic plant. It was first recorded in New Zealand in 1906 and is distributed ...
Towards integrated pest management of phythophagous insects in Tasmanian blackwood (Acacia melanoxylon) plantations in New Zealand
(Lincoln University, 1999)
Acacia melanoxylon provenance trials were assessed to investigate: (1) The degree to which insect populations influence growth and the change from juvenile to mature foliage. (2) How tree growth rates and overall performance ...
