Insect Pests and Spiders in Oilseed Rape and Their Response to Site and Landscape Factors,ty of spiders, and density, body size and offspring of the wolf spider, ., in oilseed rape fields relative to site and landscape factors were investigated. Abundances of pollen beetles and stem weevils were significantly positively correlated with soil quality and negatively related to oilseed rape

Impact of Insecticides on Parasitoids of Oilseed Rape Pests,studies show that the insecticide product, the dose rate and the timing of application can affect parasitoid abundance and levels of parasitism differentially. Insecticides applied during flowering have most potential to threaten parasitoid populations. This knowledge will help in the future to prov

Farming Systems, Integrated Crop Management and Winter Oilseed Rape Production,ient, providing a good net return. Integrated crop management aims to achieve a sustainable farming system by using natural resources and regulating mechanisms to replace polluting inputs. In oilseed rape production, nitrogen inputs to the crop and machinery use are greater than for many other crops
