    Technique of pneumatic pest control – analyses and a new device

    Get PDF
    Pest control in organic production of berries, potatoes and vegetables usually employs spreading technique of registered phytopharmaceutical agents. This technique may be supported or even replaced by pneumatic pest control. Pneumatic pest control means suction of pest using a vacuum device similar to a home vacuum cleaner. Up to now there is no evaluation of pneumatic pest control available from an agricultural engineering point of view. This paper concerns the following questions: Which techniques of pneumatic pest control are available and how may these techniques be improved in terms of technical and physical parameters? Based on the answers a new device design is presented

    Pest Resistance Regulation and Pest Mobility

    We use a spatially-explicit analytical framework to compare mandatory refuges and a tax on the resistant variety as regulation instruments for pest resistance management. Because the extraction of the common-pool pest susceptibility resource depends on the spatial pattern of pest dispersal, we find that the usual preference for market-based environmental instruments does not necessarily apply to pest resistance management. Mandatory refuges are preferred to a tax on the resistant variety for some assumption sets on heterogeneity between farms and pest dispersal distances.Environmental Economics and Policy,

    Interface between pest risk science and policy : the EPPO perspective

    The European and Mediterranean Plant Protection Organisation (EPPO) is an intergovernmental organization responsible for cooperation in plant protection in the European and Mediterranean region. It provides global distribution maps of pests, and intends to identify the areas at risk from new and emerging pests, in the framework of Pest Risk Analyses. EPPO has developed a decision-support scheme for Pest Risk Analysis (DSS) and a computer program (CAPRA) to assist pest risk analysts in running the decisionsupport scheme. Dedicated rating guidance and a Climatic Suitability Risk Mapping Decision-Support Scheme have recently been developed to guide assessors in identifying the potential area of establishment of a pest. All these tools have been developed taking into account both pest risk science available and needs of policy makers. The use of these tools and of mapping software are undertaken within the framework of EPPO Pest Risk Analyses, as illustrated through the examples of Thaumatotibia leucotreta (Lepidoptera) and Apriona germari (Coleoptera)

    The Battle over Sunrise Rock: Examining the Constitutionality of Government Land Transfers to Private Entities

    Among the 1.6 million acres of southern California’s Mojave National Preserve stands a small cross, erected nearly a century ago as a memorial to veterans who died in World War I. Located in a remote site in the desert atop an outcropping known as Sunrise Rock, the cross, standing between five and eight feet tall,may appear to be of little significance to the average passerby. However, this seemingly inconsequential monument may have substantial implications for the federal government’s ability to transfer land to private entities. The location of the cross in the federally-owned Preserve has sparked widespread debate over whether it violates the First Amendment’s Establishment Clause, which guarantees that “Congress shall make no law respecting an establishment of religion.”The Establishment Clause is generally interpreted to guarantee citizens the right to be free from the government’s endorsement of a particular religion.Opponents of the cross have sought its removal for more than a decade, arguing that its location on the Preserve constitutes governmental endorsement of Christianity

    Ground Beetles (Coleoptera: Carabidae) Collected by Pitfall Trapping in Michigan Small-Grain Fields

    Get PDF
    (excerpt) During the 1980 growing season a series of standard, single-cup pitfall traps were maintained in wheat, oat, barley, and rye fields in Michigan. The traps were maintained by Pest Management Field Assistants (PMFAs) and entomology students from Michigan State University. The traps were primarily used to monitor insect pest activity as part of pest management scouting

    Matching methods to produce maps for pest risk analysis to resources

    Decision support systems (DSSs) for pest risk mapping are invaluable for guiding pest risk analysts seeking to add maps to pest risk analyses (PRAs). Maps can help identify the area of potential establishment, the area at highest risk and the endangered area for alien plant pests. However, the production of detailed pest risk maps may require considerable time and resources and it is important to match the methods employed to the priority, time and detail required. In this paper, we apply PRATIQUE DSSs to Phytophthora austrocedrae, a pathogen of the Cupressaceae, Thaumetopoea pityocampa, the pine processionary moth, Drosophila suzukii, spotted wing Drosophila, and Thaumatotibia leucotreta, the false codling moth. We demonstrate that complex pest risk maps are not always a high priority and suggest that simple methods may be used to determine the geographic variation in relative risks posed by invasive alien species within an area of concern
