摘要: Abstract In 2001 and 2002, grapevines in southcentral Washington were surveyed to assess taxonomic composition, density, phenology of spider mites predaceous phytoseiid mites. To determine how management intensity affected the mite fauna we compared densities among, 1) non-managed not exposed any chemical input, 2) managed vineyards fungicides herbicides, 3) fungicides, insecticides acaricides. Because use non-selective pesticides often results higher pest due negative effects on predators, our hypothesis was that as input increased, would increase while decrease. Tetranychus mcdanieli McGregor most abundant samples. Spider lowest sites receiving no similar low high vineyards. Galendromus occidentalis (Nesbitt...
