Populations may diverge at fitness-related genes as a result of adaptation to local conditions. The ability to detect this divergence by marker-based genomic scans depends on the relative magnitudes of selection, recombination, and migration. We survey rat (Rattus norvegicus) populations to assess the effect that local selection with anticoagulant rodenticides has had on microsatellite marker v...

Since 1984 pest control operatives in some inner-city areas in the U.K. have found that house mice have become increasingly difficult to control. Mice in these very localised areas have stopped taking rodenticide bait from bait containers, a phenomenon referred to here as behavioural resistance. We report here preliminary experiments designed to characterise the phenomenon more precisely by com...

Knowledge on anticoagulant resistance has made considerable progress during recent years, due in particular to the investigation of the genetic basis of the enzyme-complex involved, and the introduction of new test methods. The Rodenticide Resistance Action Committee (RRAC) of CropLife International therefore invited leading scientists from six countries to a seminar with the objective to revie...

Background: Poisoning cases is a significant contributor to mortality and morbidity all over the world. Acute poisoning cases form one of the commonest causes of emergency hospital admissions. Material and methods: It is a retrospective study of 106 poisoning cases admitted in M.A.P.I.M.S., which is a tertiary health care centre Results: The incidence of poisoning poison was insecticide/ rodent...

Phosphine is a food fumigant, used until now as an insecticide and rodenticide. The present work researches the action of phosphine treatment on growth and aflatoxin production of 23 Aspergillus strains. Production of aflatoxins B1, B2, G1, and G2 decreased in almost all cases by a ratio of 10 to 100. Phosphine treatment therefore seems favorable to prevent growth of various Aspergillus strains...

Single acute doses of the rodenticide brodifacoum were administered orally to 13 species of birds which are at risk from accidental poisoning during rabbit or possum control operations. Median lethal dose values from less than 1 to more than 20 mg/kg were obtained for some species. Gulls and Canada geese appear to be particularly susceptible. Several species, particularly the gulls, waxeyes, sp...
