    Description / Table of Contents: Résumé Les réponses antennaires ont été examinées par électroantennogramme aux odeurs de plantes hôtes et non hôtes d'orthoptères Gomphocerinae de comportements alimentaires différents: Bootettix argentatus, monophage sur une dicotylédone, Larrea; Ligurotettix coquilletti, oligophage de dicotylédones; Cibolacris parviceps, polyphage; Chorthippus curtipennis, graminivore. Les types de réponse des quatre espèces étaient très voisins, mais les réponses aux odeurs de Larrea de B. argentatus et L. coquilletti, spécialistes de cette plante, étaient relativement plus fortes. Ces résultats suggèrent une similarité globale considérable dans la composition des populations de récepteurs olfactifs de ces quatre espèces d'orthoptères mais aussi une certaine spécificité pour les odeurs de la plante hôte au niveau antennaire.
    Notes: Abstract Antennal responses to host and non-host odours were recorded, using the electroantennogram technique, from four gomphocerine grasshoppers with different feeding habits: Bootettix argentatus (monophagous on Larrea, a dicotyledonous plant), Ligurotettix coquilletti (oligophagous on dicotyledonous plants), Cibolacris parviceps (polyphagous) and Chorthippus curtipennis (graminivorous). The patterns of responses across the plant odours were similar for all four grasshopper species, but there was a relatively greater response to the odour of Larrea in B. argentatus and L. coquilletti which specialise on this plant. This suggests that there is considerable overall similarity in the make up of the olfactory receptor populations of these four grasshoppers species, but that some specificity for hostplant odour does exist at the antennal level.

    Notes: Abstract Residual deposits of fluvalinate caused two-spotted spider mite,Tetranychus urticae Koch, dispersal by running off (run-off) and spinning down (spin-down) from treated leaves. Run-off occured at concentrations from 0.0005 g a.i. 1−1 and reached a peak at 0.01 g a.i. 1−1. Spin-down was more predominant at concentrations above 0.01 g a.i. 1−1. Spin-down and run-off proportions varied with fluvalinate formulation. Oviposition was temporarily suppressed on fluvalinate-treated leaves, presumably because of an irritant effect which reduced feeding. An emulsifiable concentrate formulation caused the largest reductions in oviposition. Oviposition returned to the level exhibited by untreated mites two days after removal from treated surfaces. Oviposition and feeding were positively correlated and both declined reciprocally with increasing fluvalinate concentration.

    Description / Table of Contents: Zusammenfassung Titan-Ferrocolumbit ist ein seltenes Akzessorium in den Spodumenpegmatiten der Weinebene, Kärnten, Österreich. Er enthält entmischten niobhaltigen Rutil und selten Einschlüsse von möglicherweise primärem Zinnstein. Die Zusammensetzung des TitanFerrocolumbits ist relativ homogen und weist die folgenden Elementverhältnisse auf. Mn/(Mn + Fe) 0,24 – 0,33, Ta/(Ta + Nb) 0,09 – 0,13 (Atomverhältnisse) und 0,47 – 0,88 Ti pro 12 Kationen (2,7 - 5,0Gew.%TiO2). Natürlich auftretende Kristalle sind strukturell merklich ungeordnet und erlangen durch Erhitzen einen höheren Ordnungsgrad. Die Mn/(Mn + Fe) sowie Ta/(Ta + Nb) Verhältnisse des niobhaltigen Rutil betragen 0,00 – 0,04 bzw. 0,26 – 0,38. Der niobhaitige Rutil ist im Vergleich zu Mn- und Nb-führendem Ferrocolumbit an Fe, Ta, Ti und Sn angereichert.—Die Seltenheit von Nb, Ta-Oxiden in den spodumenführenden Pegmatiten der südlichen Ostalpen steht in Übereinstimmung mit ihrer Zugehörigkeit zum Albit-Spodumen Typ der selten-Element-führenden Pegmatite (rare-element pegmatites).
    Notes: Summary Titanian ferrocolumbite is a rare accessory mineral in the spodumene-bearing pegmatites at Weinebene, Carinthia, Austria. It contains abundant exsolved niobian rutile and scarce inclusions of cassiterite that may be primary. The titanian ferrocolumbite is relatively homogeneous with Mn/(Mn + Fe) 0.24–0.33, Ta/(Ta + Nb) 0.09–0.13 (atomic ratios) and 0.47–0.88 Ti per 12 cations (2.7–5.0 wt.% TiO2). Natural specimens are considerably disordered but become more ordered on heating. Niobian rutile has Mn/(Mn + Fe) 0.00–0.04 and Ta/(Ta + Nb) 0.26–0.38; it concentrates Fe, Ta, Ti and Sn relative to the Mn- and Nb-enriched ferrocolumbite. The overall scarcity of Nb, Ta-oxide minerals in the spodumene-bearing pegmatites of southern Ostalpen conforms to their general features ranking them with the albite-spodumene type of rare-element pegmatites.

    Notes: Abstract Four fluvalinate formulations differed in their residual toxicity to female two-spotted spider mite (TSM), Tetranychus urticae adults; the emulsifiable concentrate (EC) was the most toxic. In contrast, there was little difference in toxicity between the formulations with the European red mite (ERM) Panonychus ulmi with the exception of the EC formulation which was the least toxic. Fluvalinate 2F caused minimal (〈10%) TSM and ERM egg mortality. Fluvalinate 2F was more toxic and caused greater larval dispersal for the TSM compared to the ERM at the field concentration and below. The toxicity of fluvalinate 2F to TSM and ERM protonymphs, deutonymphs and adults was low, approximately 〈20% at field concentration. Dispersal was the main response to fluvalinate and this was positively correlated with increasing concentration. The combined mortality and dispersal LC50 was five times lower for ERM protonymphs and adults, but 11 times higher for ERM deutonymphs compared to equivalent TSM life stages. Fluvalinate 2F reduced TSM development from the protonymph and deutonymph stages to a greater extent compared to the ERM. The mortality response to fluvalinate 2F was unaffected by host type (peach or apple) for the TSM whereas ERM mortality was higher on apple compared to peach. TSM dispersal was higher from apple compared to peach whereas ERM dispersal was similar on both host types. Oviposition by both mite species was lower on apple than peach leaves. A 1 h exposure to fluvalinate 2F reduced ERM oviposition for 12 days.
