Current issues in rodenticide anticoagulant resistance testing are reviewed. Research and management issues for New Zealand agencies include: 1. Assessing and monitoring the spread of resistance. 2. Standardising and improving resistance-testing techniques. 3. Identifying from the range of tests that have been developed for assessing rodenticide resistance which is the best to use. 4. Developin...

Polyethylenimine (PEI) has been proposed as a non-viral vector, and has been successfully used to transfer reporter genes into the central nervous system (CNS), kidneys, and lungs of adult mice. Neuropeptide Y (NPY) is a peptide expressed in the hypothalamus and is important in the regulation of body weight. Using PEI combined with stereotactic microinjection, we have successfully transferred c...

Large-scale rodent control can help to manage endangered species that are vulnerable to invasive rodent consumption. A 26 ha rodent snap-trap grid was installed in montane forest on Oahu Island, Hawaii, in order to protect endangered snails and plants. To assess the effectiveness of this trapping operation in reducing fruit consumption and seed predation of the endangered Hawaiian lobeliad, Cya...

The disadvantages of the acute, fast-acting, rodenticides are well understood by the specialist. However, despite poison-shyness and consequent short-lived, low efficacy rodent control, many users prefer "acutes" such as zinc phosphide to "first-generation" anticoagulants of the warfarin type. The techniques necessary for efficient use of the first-generation anticoagulants are often inappropri...

Background and Aims: The aim of this study is to clarify nitric oxide (NO)-production by spleen and the importance of spleen in malaria infection in murine model. Materials and Methods: Thirty outbred NMRI female mice were divided into four groups, Group I: No intervention (Healthy control), Group II: With splenectomy (Healthy test), Group III: No intervention, Inoculation of contaminated bloo...

Rodent baits containing systemic insecticides are potential tools to interrupt the cycle of transmission of Leishmania parasites by killing sand flies that take bloodmeals from rodents as adults. Bio-indicators that can be used in conjunction with rodent-targeted sand fly control methods also have been developed to demonstrate that the insecticide treatments are reaching the targeted life stage...

Hantaviruses are the causative agents of the zoonotic diseases known as haemorrhagic fever with renal syndrome (HFRS) in Europe and Asia, and hantavirus pulmonary syndrome (HPS) in the Americas. These pathogens are maintained in the wild by rodent reservoirs and are mainly transmitted via the aerosol route. The infection is chronic and apparently asymptomatic in host animals. Whilst HFRS is cau...

abstract background: zoonotic cutaneous leishmaniasis (zcl) is one of the most important vector-borne diseases in iran. wild rodents play as a reservoir. the main aim of this study was to determine spatial analyses of the relationship between rodent’s active burrows and incidence of zcl in golestan province, north east of iran . methods : the cross-sectional study was conducted in 59 rural dist...

Abstract This paper provides a broad overview of spatial, architectural, and sensory relationships between rats humans on British American vessels from approximately the 1850s–1950s. Taking as my primary historical actors, I show how attempted to prevent movement these animals ports across three periods. Firstly, mid- to- late-nineteenth century, where few attempts were made boarding ships, mul...

World food shortages become more acute each year, and all too often, rodents are present to take their unwarranted share. To counter this, we must refine our rodent control methods to make them more efficient. To this end, correct bait selection is essential. Grain baits must be selected for purity and acceptability. Grain alterations must be carefully controlled, as well as any additives. Mult...
