title: Detrimental effects of water extracts from surface and interior of Taxus baccata leaves on the two-spotted spider mite (Tetranychus urticae Koch).
abstract: Surface deposits on Taxus baccata needles removed by dipping in water of 96, 60 or 40 degrees C for 5 s caused changes in life history components of mites. Paclitaxel was among other peaks present in the removed fractions in concentrations between 0.017 and 0.170 microg/g of fresh weight (f.w.) increasing with temperature. Long extraction for 60 min at only 40 degrees C did not increase removable paclitaxel, but at 60 degrees C extraction rate was the highest (1.326 microg/g) suggesting that leakage from an interior of needles occurred. Mortality, developmental time, total fecundity, oviposition period and life history parameters of Tetranychus urticae Koch. were detrimentally affected.
