Prospective generalist invertebrate predators for conservation biological control of the vineyard pests Epiphyas postvittana and Pseudococcus calceolariae
(Lincoln University, 2015)
A series of field surveys and experiments were performed to identify generalist invertebrate predators which could complement the parasitoid Dolichogendia tasmanica in management of the vineyard pest Epiphyas postvittana ...
Understanding protoplast technology as a tool to enhance biocontrol
(Lincoln University, 2018)
Biocontrol of plant pathogens is an integral part of modern pest and disease management. Issues of pesticide residues/resistance and a drive towards sustainability within crop protection systems have created an opportunity ...
Studies on the Efficacy of Three Trichoderma atroviride Isolates for Controlling Take-all (Gaeumannomyces graminis var. tritici) in Grasses
(Lincoln University, 2018)
Take-all, caused by the fungal pathogen Gaeumannomyces graminis var. tritici (Ggt), is an internationally important widespread root disease of cereals and grasses. The disease is suspected as the main cause of the increasing ...
Plant-mediated effects of Trichoderma spp. and Beauveria bassiana isolates on insect and pathogen resistance
(Lincoln University, 2017-02-27)
Brassica oleracea var. capitata is grown worldwide under temperate to tropical climate conditions. However, cabbage is attacked by a wide range of insect pests and plant diseases. The phloem-feeding green peach aphid, Myzus ...
Interactions between isolates of the fungus Beauveria bassiana and Zea mays
(Lincoln University, 2017)
Entomopathogenic fungi from the genus Beauveria play an important role in controlling insect populations and have been utilised widely for the biological control of insect pests. Only relatively recently has research focused ...
The gorse pod moth (Cydia succedana Denis & Schiffermüller); is it a successful gorse (Ulex europaeus L.) biological control agent?
(Lincoln University, 2015)
Most weeds that cause issue for agricultural production in New Zealand have been imported. One such imported and well-established weed, Ulex europaeus L. (gorse), was declared a noxious weed in New Zealand in 1900. Since ...
The effect of landscape- and local-scale non-crop vegetation on arthropod pests and predators in vineyards
(Lincoln University, 2012)
Experiments were conducted to assess any influence of the landscape and local
(‘field’ scale) non-crop vegetation on conservation biological control (CBC) via
predation of insect pest eggs in vineyards.
In the 19th Century, ...
Biological control of Rhizoctonia diseases of potato
(Lincoln University, 2012)
Potato (Solanum tuberosum L.) is one of the most important crops in New Zealand and internationally. Potato plants are susceptible to a range of pathogenic diseases, including the Rhizoctonia diseases, which are globally ...
The potential of Cleobora mellyi (southern ladybird) as a biological control agent of the invasive tomato-potato psyllid (Bactericera cockerelli) on potatoes
(Lincoln University, 2013)
Invasive species cause large annual economic losses worldwide, including the New Zealand agricultural and horticultural sectors, and threaten our native and endemic species. Insects are some of the most damaging invasive ...
Host-parasitoid avoidance behaviour in the context of contemporary evolution in insect classical biological control : A thesis submitted in partial fulfilment of the requirements for the Degree of Doctor of Philosophy at Lincoln University
(Lincoln University, 2019)
Pests are increasingly invading novel environments due to global trade and travel and their management requires a greater emphasis on classical biological control than has previously been the case. This approach has been ...
