Environmental factors and agronomic practices associated with Savi’s pine vole abundance in Italian apple orchards

Long Term Vole Control in Ontario Apple Orchards

'!he results obtained so far in this 3 year study have shown that the plots with poisoned bait feeder stations suffered significantly less tree girdling than the plots treated with the fall broadcast application of 2% zinc phosphide. Similar timings were also observed in number of voles per plot, however, the vole population was much lower than the previous year. Cbnsiderable interest has been ...

Radiotelemetric Evaluation of the Effect of Horticultural Practices on Pine and Meadow Voles in Apple Orchards: Ii. Herbicide Application

Pine voles (Microtus pinetorum) and meadow voles (Microtus pennsylvanicus) were studied in a commercial apple orchard in the Hudson Valley of New York during April and May 1981. Selected voles were given miniature radiotransmitters and then tracked before and after herbicide application. A total of eight pine and meadow voles were tracked throughout the experimental period. H0m.e range size dec...

Analysis of Seasonal Dynamics of Pine Vole Populations in Two Virginia Orchards

Bird diversity and abundance in organic and conventional apple orchards in northern Japan

Many studies have investigated the benefits of agri-environmental schemes, such as organic farming, on biodiversity conservation in annual systems, but their effectiveness in perennial systems is less well understood, particularly in bird communities in temperate regions of Asia. This study examined the effects of organic farming practices on species richness and abundance of breeding birds in ...

Accumulation of lead and organochlorine residues in captive American kestrels fed pine voles from apple orchards.

Pine voles (Microtus pinetorum) were collected from pesticide-treated orchards in New York (USA) and fed to three captive American kestrels (Falco sparverius) for 60 days to evaluate potential hazards from soil-borne persistent insecticides. Three control kestrels were fed uncontaminated laboratory mice (Mus musculus). The pine voles contained an average of 38 ppm lead, 48 ppm DDE and 1.2 ppm d...
