Conservation biological control in a multi-strata agroforestry system
… of the system claim that it will advance conservation goals by providing ecosystem services like habitat provision and carbon sequestration, but also provide localized ecosystem services that benefit farmers. Pest control by wild predators and parasitoids could be an especially valuable …

Habitat manipulation for conservation biological control in organic Vegetable crops
O controle biológico é a principal estratégia utilizada na agricultura orgânica para prevenção dos danos causados por artrópodes praga. Para que o controle biológico possa ser favorecido, a manipulação de habitats nos agroecossistemas deve prover recursos e condições adequadas para a conservação e …

The influence of native plants on arthropod population dynamics: can native plants enhance conservation biological control
Conservation biological control aims to maintain sustainable natural enemy populations. Through increased urbanization, alien vegetation is being planted; these plants may be unacceptable hosts for herbivores. We tested the prediction that urban landscapes composed of native plants host a diverse …

Food webs and phenology models: evaluating the efficacy of ecologically based insect pest management in different agroecosystems
… information, in combination with available pest control methods, is used to manage pest populations by the most economical means, and with the least possible hazard to people, property, and the environment. True IPM takes advantage of all appropriate pest management options including, as …

Effect of buckwheat (Fagopyrum esculentum) on the abundance and efficacy of the leafroller parasitoid (Dolichogenidea tasmanica) in a Blenheim vineyard : A dissertation submitted in the partial fulfilment of the requirements for the degree of Bachelor of Science with Honours at Lincoln University
… buckwheat strips were alternated with eight control strips (grassed) at Squire Estate vineyard, Blenheim. Two yellow 'Trappit' sticky traps per buckwheat and control row were used to catch D. tasmanica over four successive fortnightly trapping periods. Significantly higher numbers of D. …

Ecosystem services provided by native New Zealand plants in vineyards
… native plants provide would give cause for their conservation and restoration; as these services may improve agricultural sustainability. This study assessed several ES that native plants potentially provide. These included conservation biological control (CBC), marketing opportunities, …

Integration of High Residue/No-till and Farmscaping Systems in Organic Production of Broccoli
… to the improvement of soil quality and weed control. Although, during transition from chemical to organic cover-cropping production, especially with no-till systems, reduction of nitrogen availability to the main crop and increase in weed and pest pressure may occur. In 2004-2005, summer and …

Assessing adaptive winter behaviors of beneficial arthropods, with a focus on the long-distance migratory ecology of Nearctic hover flies (Diptera: Syrphidae)
… and non-crop plant species, while larvae act as biological control agents for major crop pests such as aphids. Despite these benefits, major aspects of their life histories remain unknown, especially for taxa outside of Europe. For example, while several Palearctic hover fly species are known to …

Enhancing the biological control of leafrollers (Lepidoptera: Tortricidae) using floral resource subsidies in an organic vineyard in Marlborough, New Zealand
… (Hymenoptera: Braconidae) could enhance the biological control of leafrollers (Lepidoptera: Tortricidae) in an organic vineyard in Marlborough, New Zealand. Laboratory experiments were conducted to find a selective floral resource that could enhance the 'fitness' of the parasitoid, D. …
