    Notes: [Auszug] RECENT studies on the growth of potato plants in Australia by Bald and Hutton1 indicate that all varieties of potatoes grown under identical conditions are likely to show similar growth-rates during the early stages of vegetative development. Earlier, Bald2 had propounded a general plan of growth ...

    Notes: Treatment of soil in October 1963 with 60 1b (a.i.)/acre (67⋅3 kg/ha) quintozene or 400 1b acre (448⋅4 kg/ha) D-D killed more than 95 per cent of the Longidorus elongatus present and largely prevented transmission of raspberry ringspot and tomato black ring viruses to ‘Red-gauntlet’ strawberry planted in April 1964. The herbicide chloroxuron at 5 1b (a.i)/acre (5⋅6 kg/ha) did not affect L. elongatus numbers but delayed infection of the strawberry plants by controlling weed sources of virus. Quintozene and D-D increased fruit yields four to six-fold in 1965 and nine to twelve-fold in 1966; chloroxuron caused only small increases. Quintozene persisted in the soil for several years but was not detected in strawberry fruit. In an experiment on virus-free soil, quintozene had no effect on ‘Talisman’ strawberry or ‘Mailing Jewel’ raspberry, but adversely affected growth of ‘Lloyd George’ raspberry and sugar beet. L. elongatus migrated slowly through soil and congregated in the root zone of strawberry plants. Populations in untreated plots increased about two-fold per year. Eggs were laid from April to July.

    Notes: The effect of milk feeding on the ontogeny of serum IgA in breast and cow milk formula fed neonates was studied. There was a rise in serum IgA concentrations from the 2nd week in both groups, but no difference in rate of appearance or concentrations in relation to age, gestation or sex. The ingestion of RSV antibody-rich colostrum was associated with a rise in serum anti-RSV IgA in 2 preterm infants during the perinatal period. We suggest that there are 2 mechanisms which regulate the ontogeny of circulating IgA: an early but small intestinal uptake of colostral IgA, and a later endogenous production, which in this study was not influenced by composition of feeds.

    Notes: The LBNL third generation electron cyclotron resonance (ECR) ion source has progressed from a concept to the fabrication of a full scale prototype superconducting magnet structure. This new ECR ion source will combine the recent ECR ion source techniques that significantly enhance the production of high charge state ions. The design includes a plasma chamber made from aluminum to provide additional cold electrons, three separate microwave feeds to allow multiple-frequency plasma heating (at 10, 14, and 18 GHz or at 6, 10, and 14 GHz) and very high magnetic mirror fields. The design calls for mirror fields of 4 T at injection and 3 T at extraction and for a radial field strength at the wall of 2.4 T. The prototype superconducting magnet structure which consists of three solenoid coils and six race track coils with iron poles forming the sextupole has been tested in a vertical Dewar. After training, the sextupole magnet reached 105% of its design current with the solenoids off. With the solenoids operating at approximately 70% of their full design field, the sextupole coils operated at 95% of the design value which corresponds to a sextupole field strength at the plasma wall of more than 2.1 T. © 1998 American Institute of Physics.

    Description / Table of Contents: Zusammemfassung Frühlingsmigranten von Aphis fabae, die ein Bohnenfeld befielen, waren hauptsächlich auf die Bestandsränder beschränkt, wo die von ihnen begründeten Kolonien “Randbefall” bildeten. Der Initialbefall nahm in der auf die primäre Migration folgenden Zeit an Dichte und Ausmaß zu, wobei die Befallsverteilung im wesentlichen die gleiche blieb wie die von den primären Zufliegern erzeugte. Der Innenteil des Feldes wurde allgemeiner befallen, als ein kleiner Teil der im Felde herangewachsenen Geflügelten in den Bestand eindrang und diesen Teil des Feldes besiedelte; jedoch faßte der Befall nicht Fuß. Auf der geschützten Leeseite des Feldes entwickelte sich ein viel schwererer Befall, obwohl die Anzahl der hier festgestellten Migranten nicht größer war als an jeder anderen Seite des Feldes. Es wird daraus geschlossen, daß die verhältnismäßig ruhigen Bedingungen auf dieser geschützten Seite eine größere Flugaktivität der einfallenden Frühjahrszuwanderer gestattete und daher jeder von ihnen eine größere Anzahl von Pflanzen infizierte als die Migranten in anderen Teilen des Feldes. Es wird angenommen, daß physikalische Wirkungen des Windschutzes, z.B. höhere Temperaturen, Ursache dafür waren, daß an dieser Seite größere Kolonien beobachtet wurden.
    Notes: Abstract The infestation pattern in a bean field is related to the effects of shelter on the activity of the migrants and developing apterous colonies.
