A comparative phenetic and cladistic analysis of the genus Holcaspis Chaudoir (Coleoptera: Carabidae)
(Lincoln University, 1994)
The systematics of the endemic New Zealand carabid genus Holcaspis are investigated, using phenetic and cladistic methods, to construct phenetic and phylogenetic relationships. Three different character data sets: ...
Effects of insecticides on Sitona discoideus (Gyllenhal) (Coleoptera: Curculionidae) and its parasitoid Microctonus aethiopoides (Loan) (Hymenoptera: Braconidae)
(Lincoln University, 1991)
Laboratory and field experiments were conducted to evaluate the effect of insecticides on the egg and adult stages of Sitona discoideus (Gyllenhal), and its natural enemy Microctonus aethiopoides (Loan). A range of ...
Starling (Sturnus vulgaris L.) predation on grass grub (Costelytra Zealandica (White), Melolonthinae) populations in Canterbury
(Lincoln College, University of Canterbury, 1972)
The main object of this study was to investigate the effects of predation by starlings (Sturnus vulgaris) on populations of the grass grub (Costelytra zealandica) in Canterbury, with the secondary objective of investigating the ...

(Lincoln College, University of Canterbury, 1975)
During the 1973 flight season of the grass grub beetle, Coatelytra zealandica (White), an attempt was made to suppress populations on small scale field plots by mass trapping male beetles using simple water traps baited ...
Spatial aspects of bumble bee (Bombus spp. Apidae) foraging in farm landscapes

Bumble bees (Bombus spp.: Apidae) are valuable pollinators of many crop and wildflower species. However, in some situations their potential is limited. Evaluation of, and management to improve bumble bee efficacy should ...
Interactions between soil biogeochemistry and native earthworms in New Zealand
(Lincoln University, 2016)
Despite apparently similar burrowing and feeding behaviours to introduced Lumbricidae earthworms, native Megascolecidae, with more than 179 recognised species, have become isolated in natural vegetation remnants on the ...
Comparative studies on the toxicity of selected Acaricides to susceptible and resistant strains of Tetranychus urticae Koch (Acarina : Tetranychidae)
(Lincoln College, University of Canterbury, 1966)
Although scientific knowledge on insect resistance to chemicals has advanced spectacularly during the last few years it is not possible to apply directly these findings to resistance within the order Acarina. Not only are ...
Insect pest resistance : technological, biological and economic dimensions
(Lincoln College, University of Canterbury, 1984)
The literature on pest control technology, biology and economics is reviewed. The problem of resistance is considered in economic terms. Pest susceptibility is defined as a resource and because of a lack of property rights, ...
