    Notes: Abstract Like other flower thrips, Frankliniella schultzei Trybom (Thysanoptera: Thripidae) feeds on pollen. However, the influence of a pollen diet on the life history of F. schultzei may not be as significant as reported for other thrips species. Frankliniella schultzei was reared successfully and with low mortalities (≤20%) on Wax Mallow, (Malvaviscus arboreus Cav.) plant part diets. Development times and fecundity on a petal diet were not significantly different from that on a pollen diet. Fecundity on a diet combining M. arboreus pollen, petal and leaf tissues was significantly higher than those individually containing these tissues. In laboratory choice tests, F. schultzei females encountered petal most often of the three plant parts. Pollen and leaf were encountered with similar frequencies. A significantly higher proportion of petal encounters (0.8) resulted in feeding than did pollen encounters (0.5). Few leaf encounters (0.1) were followed by feeding. Adult and larval F. schultzei were found in M. arboreus flowers but not on leaves. All parts of the flower were inhabited and not just the pollen-bearing petal apices and anthers. We propose that feeding on pollen within M. arboreus flowers is just one of many influences on the life history of F. schultzei and suggest that this may extend to other thrips species/host-plant combinations.

    Fate of sheep urine-N applied to an upland grass sward (1986)
    Springer
    Plant and soil 91 (1986), S. 425-427

    ISSN: 1573-5036
    Keywords: Lolium perenne L ; Nitrogen uptake ; Sheep urine-N ; Soil mineral N

    Notes: Summary Sheep urine was applied once in August to 1 m2 plots of a N-deficientLolium perenne-dominated sward at a rate equivalent to a single urination (48 g N m−2) at an upland site. After 17 days herbage dry matter (DM) and total N were increased 19- and 63-fold respectively compared with a control receiving water only. Soil mineral N (NH 4 + and NO 3 − ) levels in the top 20 cm were greater in urine plots until 30 days after urine application when cumulative yields of herbage DM and N were 10 and 21 times greater than those of the control. Maximum recovery of urine N by herbage was only 16% of that applied, and, although swards responded rapidly to urination there were substantial losses of N, perhaps via leaching and/or volatilisation, from the soil-plant system.
