Biological control of purple loosestrife, Lythrum salicaria L.(Lythraceae) with Galerucella sp. (Coleoptera: Chrysomelidae): dispersal, population change, overwintering ability and predation of the beetles, and impact on the plant in southern Manitoba wetland release sites / Jason K. Diehl
Material type: TextSeries: Thesis ; (M.Sc.)Publication details: Winnipeg, MB : University of Manitoba, 1999.Description: xii, 207 p. : ill. ; 28 cmAbstract: Managers of wetlands across eastern North America have struggled for years to break-up monospecific stands of cattail, Typha spp. in order to increase the abundance and diversity of wildlife inhabiting such areas (Thompson et al. 1987). Today, instead of cattail, the struggle continues with the introduced species, Lythrum salicaria L.(Lythraceae), which outcompetes Typha spp. and other wetland plant genera such as Carex spp. and Phalaris spp., leading to the formation of large monospecific areas of the weed (Smith 1964; Stuckey 1980).Compared to cattail, these large areas of purple loosestrife are believed to provide a less suitable habitat for wetland wildlife (Mckeon 1959; Smith 1964). The importance of prairie wetlands in the population biology of migratory wildfowl is one factor contributing to establishment of a control program against purple loosestrife in the Prairie Provinces.Item type | Current library | Collection | Call number | Status | Date due | Barcode |
