    The relationship between the size of yellow water traps and catches of aphids (1967)

    Notes: Abstract Yellow water traps are often used for sampling populations of flying aphids. This note suggests that the size and probably the shape of traps should be standardised, because trapping efficiency (nos. caught/unit area), and the relative attractiveness of traps to different species, depends on trap size. Aphidologists using water traps to compare mixed populations of flying aphids, should therefore compare catches from different traps with caution. Traps of three sizes were made up from individual trays, each 29×21.5×5cm, and painted Hansa yellow inside; 1 tray alone, 4 arranged in a 2×2 rectangle, and 9 in a 3×3 rectangle, gave trapping surfaces of approx. 625, 2500 and 5700 cm2 respectively. The traps were half-filled with water plus a drop of detergent, placed on bare land and daily catches collected on 19 days in June and July 1966.

    Description / Table of Contents: Sommaire Les Thysanoptères qui flottaient autour et au-dessus d'un champ de blé étaient attrapés par le moyen de pièges à l'eau noirs, verts ou blancs, de pièges cylindriques qui étaient visqueuz et noirs et d'aspirateurs. De certaines espèces des genres Taeniothrips, Thrips et Aeolothrips étaient très attirées par le blanc mais pas par le vert ni le noir: les espèces Limothrips cerealium Hal., Chirothrips manicatus Hal., et Stenothrips gramium Uzel n'étaient pas notablement attirées par chacune de ces couleurs. Au niveau des épis les données obtenues avec les aspirateurs étaient plus justes que ne l'étaient celles obtenues avec les pièges à glu ou les pièges à eau: plus haut les pièges à glu indiquaient des données plus justes que les pièges à eau. Jusqu'à quinze mètres environ de hauteur la densité aérienne de toutes les espèces diminuaient progressivement, mais la rapidité de la diminution était différente entre les espèces.
    Notes: Abstract Thysanoptera drifting over and around a wheat field were trapped using black, green and white water traps, black cylindrical sticky traps and suction traps. Certain Taeniothrips spp., Thrips spp., and Aeolothrips spp. were strongly attracted to white but not to green or black; Limothrips cerealium Hal., Chirothrips manicatus Hal., and Stenothrips gramium Uzel were not markedly attracted to any of these colours. At crop level suction traps gave more consistent catches2 than either sticky or water traps; at higher levels, catches from sticky traps were more consistent than those from water traps. Up to 48 ft the aerial density of all species decreased with height but the rapidity of the decrease differed between species.

    The annual cycle of Limothrips cerealium haliday (Thysanoptera) and its distribution in a wheat field (1959)

    Description / Table of Contents: Sommaire Les populations terrestres et aériennes de l'espèce L. cerealium (Thysanoptères) étaient étudiées simultanément: des dissections ovariques étaient faites pour discerner les générations différentes. On peut arbitrairement diviser la vie de ces insectes en six périodes, basées principalement sur l'activité aérienne: au printemps les femelles se nourrissent pour la plupart d'herbes et de céréales d'hiver; en juin et juillet beaucoup d'elles passent sur les céréales de printemps, où elles pondent la plupart des oeufs dans les gaines des jeunes feuilles. Les femelles de la première génération laissent les céréales en aôut pour se nourrir d'herbes avant d'hiverner. Les Thysanoptères abandonnaient les épis dont la teneur en eau était approximativement moins de quarante-cinq pour cent. Quand le vent soufflait constamment du même côté l'infestation initiale était plus forte au bord du champ qui se trouvait exposé au vent.
    Notes: Abstract Terrestrial and aerial populations of L. cerealium were studied simultaneously; ovarian dissections were made to detect different generations. The annual life cycle can be arbitrarily divided into six stages based primarily on the amount of flight activity: the females feed mainly on winter cereals and grasses in spring, many moving to later sown cereals in June and July, where most eggs are laid in the sheaths of the young leaves. First generation females leave cereals in August to feed on grasses before entering hibernation. Wheat ears with a water content of less that approx. 45% were not favoured by thrips. When winds blew consistently from the same quarter the initial infestation was greatest on the windward edge of the wheat crop.

    Possible geothermal resources in the Coast Plutonic Complex of southern British Columbia, Canada (1978)
    Springer
    Pure and applied geophysics 117 (1978), S. 172-179

    Notes: Abstract In southern British Columbia the terrestrial heat flow is low (44 mW m−2) to the west of the Coast Plutonic Complex (CPC), average in CPC (50–60 mW m−2),and high to the east(80–90 mW m−2). The average heat flow in CPC and the low heat generation (less than 1 μW m−3) indicate that a relatively large amount of heat flows upwards into the crust which is generally quite cool. Until two million years ago the Explorer plate underthrust this part of the American plate, carrying crustal material into the mantle. Melted crustal rocks have produced the inland Pemberton and Garibaldi volcanic belts in the CPC. Meager Mountain, a volcanic complex in the CPC 150 km north of Vancouver, is a possible geothermal energy resource. It is the product of intermittent activity over a period of 4 My, the most recent eruption being the Bridge River Ash 2440 y B.P. The original explosive eruption produced extensive fracturing in the granitic basement, and a basal explosion breccia from the surface of a cold brittle crust. This breccia may be a geothermal reservoir. Other volcanic complexes in the CPC have a similar potential for geothermal energy.

    Description / Table of Contents: Zusammenfassung Unter Benutzung des Maximumprinzips für subharmonische Funktionen werden obere Schranken angegeben für den Gradienten des Neumannschen Problems der Potential-Theorie. Diese Schranken betreffen einem gekrümmten Streifenbereich mit von Null verschiedenen Grenzdaten an einem Ende und haben zur Folge, dass der Betrag des Gradienten exponentiell mit dem Abstand von diesem Ende abfällt.
    Notes: Abstract The maximum principle for subharmonic functions is used to obtain upper bounds for the gradient in the Neumann problem of potential theory. These bounds, which concern a curvilinear strip domain having nonzero boundary data only on an end, entail an exponential decay of the gradient magnitude with distance from that end.
