Molecular systematics and colour variation of Carpophilus species (Coleoptera: Nitidulidae) of the South Pacific
(Lincoln University, 2009)
The sap beetle genus Carpophilus Stephens (Coleoptera: Nitidulidae) is a large genus consisting of over 200 species and are found worldwide. Several species are important pests of crops and stored products, and are frequently ...
Biochemistry and genetics of carotenoid composition in potato tubers
(Lincoln University, 2009)
Potato cultivars exhibit a wide variation in skin and flesh colour due to the presence of pigments. This study established that potato cultivars differ greatly with respect to types and concentrations of carotenoids in ...
Phaeomoniella chlamydospora: potential inoculum sources in the grapevine propagation process
(Lincoln University, 2004)
Phaeomoniella chlamydospora is a recently described fungal pathogen that infects grapevines causing Petri disease, which is observed externally as a general decline. The objective of this research programme was to identify ...
Developing an optimal method for producing a tearless onion
(Lincoln University, 2008)
People experience the irritating tearing and burning sensation of lachrymatory factor (LF, propanthial S-oxide) when cutting or chopping onion bulbs. LF is produced by lachrymatory factor synthase (LFS) specifically from ...
Residual concentrations and persistence of the anticoagulant rodenticides brodifacoum and diphacinone in fauna
(Lincoln University, 2009)
Brodifacoum is a highly effective anticoagulant rodenticide that presents a secondary hazard to some non-target wildlife. The high acute toxicity of brodifacoum to mammals and birds, and its prolonged persistence in liver ...
Modelling the proximal source of intercepted exotic insects
(Lincoln University, 2009)
Biological invasions are major threats to any nation’s economy and biodiversity. To detect new biological incursions of some species biosecurity agencies deploy pheromone sentinel traps for targeted species at high risk ...
Modelling the spread of invasive species across heterogeneous landscapes
(Lincoln University, 2008)
Invasive species are well known to cause millions of dollars of economic as well as ecological damage around the world. New Zealand, as an island nation, is fortunate because it has the opportunity to regulate and monitor ...
Influence of root exudates on soil microbial diversity and activity
(Lincoln University, 2009)
Interactions between plant roots and soil microorganisms in the rhizosphere are critical for plant growth. However, understanding of precisely how root exudates influence the diversity and activity of rhizosphere microorganisms ...
Using DNA barcodes to investigate the taxonomy of the New Zealand sooty beech scale insect
(Science & Technical Publishing, Department of Conservation New Zealand, 2007-11)
It is currently proposed that there are two species of honeydew-producing sooty beech scale insects (Ultracoelostoma spp.) in New Zealand. It is thought that U. brittini lives exclusively on trunks of southern beech
(Nothofagus ...
Studies on the regulation of conidiation in species of Trichoderma
(Lincoln University, 2007)
A characteristic feature of species of Trichoderma is the production of concentric rings of conidia in response to alternating light-dark conditions. In response to a single burst of light, a single ring of conidia forms ...
