Ecological and pest-management implications of sex differences in scarab landing patterns on grape vines
BACKGROUND Melolonthinae beetles, comprising different white grub species, are a globally-distributed pest group. Their larvae feed on roots of several crop and forestry species, and adults can cause severe defoliation. In New Zealand, the endemic scarab pest Costelytra zealandica (White) causes severe defoliation on different horticultural crops, including grape vines (Vitis vinifera). Underst...
متن کاملConstant Temperature Life Table Studies of Populations of Grape Phylloxera from Washington and Oregon, USA
Grape phylloxera is a recent pest threatening to destroy over 1100 ha of selfrooted winegrapes in the Pacific Northwest region of the USA. Some vineyards have coexisted with this pest for over 15 years while others have been devastated in less than 5 years. We conducted this study to determine if life processes of populations of phylloxera from four different areas in the Pacific Northwest, USA...
متن کاملGrowth in Tissue Culture of Single-Cell Clones From Grape Stem & Phylloxera Gall.
Information about the behavior of clones of plant tissue of single-cell origin is valuable for our understanding of diseased and normal cell growth. Questions appeared about the variability of the cells in the insect-induced galls. Perhaps only a few diseased cells were responsible for the mass of abnormal, rapidly increasing cells, and the majority of the other cells provided a favorable nutri...
متن کاملFree amino Acid contents of stem and phylloxera gall tissue cultures of grape.
Free amino acid constituents were determined of grape stem and Phylloxera leaf gall callus in tissue culture. Fast, medium and slow growing single cell clones of, respectively, stem and gall origins were grown on a mineral salt-sucrose medium supplemented with coconut milk and alpha-naphthaleneacetic acid. Stem and gall clones showed qualitative similarities and quantitative variations in the a...
متن کاملPhylloxera infested grapevines have reduced chlorophyll and increased photoprotective pigment content – can leaf pigment composition aid pest detection?
Grape phylloxera is a root-feeding pest of grapevines. In Australia, phylloxera infested vineyards are subjected to quarantine restrictions and early detection remains vital for the timely implementation of post-outbreak quarantine protocols. Current detection methods rely on time-consuming ground surveying which involves detailed examination of grapevine (Vitis vinifera L.) root systems. Leaf ...
