    Correlation between rainfall in the dry season and the occurrence of the white rice borer (Scirpophaga innotata Wlk.) in Java (1959)

    Description / Table of Contents: Zusammenfassung Der Weisse Reisbohrer (Scirpophaga innotata Wlk.) kommt nur in Gebieten vor, wo jährlich eine ausgeprägte Regen- und Trockenzeit (Monsun) auftritt. Am Ende der Regenzeit gehen die vollerwachsenen Raupen, die im Stengel der reifenden Reispflanze leben, in Diapause. Während der folgenden relativ trockenen Jahreszeit, wenn nur gelegentlich Regenschauer fallen, ruhen die Raupen in der Stoppel. Bald nachdem die ersten heftigen Regenfälle der neuen Regenzeit einsetzen, verpuppen sich die Larven und alle Falter schlüpfen gemeinsam zum „Stoppelflug”. Dieser Zünsler ist in gewissen Gebieten Javas einer der Hauptschädlinge des Reises, obwohl sein Auftreten sehr unregelmäßig ist. Jahrelang war man allgemein der Auffassung, daß relativ reichlicher Regenfall während der Trockenzeit die Reisbohrerpopulation erheblich vermindere und daß in diesem Falle keine schweren Schäden durch Reisbohrerbefall erwartet werden können. Während eines Zeitraums von 26 Jahren (1915–1940) wurden in fünf Gebieten Ost-Javas sowolhl der Niederschlag wie der Bohrerschaden untersucht und Berechnungen der jährlichen Niederschlagsmenge in der Trockenzeit und des Bohrerschadens verglichen. Dies erhärtete die alte Auffassung, daß nach einer relativ feuchten oder sehr feuchten Trockenzeit kein Bohrerbefall von Bedeutung während des Beobachtungszeitraumes auftritt. Dagegen folgten in neun von 14 Jahren mit einer trockenen oder sehr trockenen Trockenzeit schwere oder ziemlich schwere Ausbrüche der Weißen Reisstengelbohrer während der folgenden feuchten Jahreszeiten. Obwohl auch andere Faktoren von einiger Bedeutung sein dürften, wird geschlossen, daß die Niederschlagsmenge während der Trockenzeit einen sehr entscheidenden Einfluß auf die Möglichkeit des Auftrétens einer Reisbohrer Kalamität im darauffolgenden Jahre hat. Diesen Daten entsprechend wird auf der Grundlage der Niederschlagszahlen in der vorangegangenen Trockenzeit ein Prognose-Schema entwickelt, wann Bohrerschaden zu erwarten ist.
    Notes: Abstract The amount of rain which falls sporadically in the relatively dry season at the time that the white rice borer is diapausing as a full grown larva in the rice stubble, has a very important influence on the size of population of the borers in the following wet season when rice is grown. If this dry season is wet or very wet (according to our standard, based on the figures of rainfall and borer damage over 26 years in five regions of Eastern Java), no damage can be expected in the following planting season. If the dry season is really dry or very dry, outbreaks of borers may occur (in the period under survey this occurred in nine out of fourteen years). We have tried to give an outline of a method of prediction of borer damage in the planting season, based on the rainfall dates of the foregoing dry season.

    Control ofLygus Campestris on carrot seed crops in North Holland (1958)

    Description / Table of Contents: Samenvatting In Noordholland werd een veldproef opgezet om de werking van DDT en dieldrin na te gaan op de populatie vanLygus campestris (L.). Deze wants tast de zaden aan van wortelen, die in de omgeving van Hoorn gekweekt worden voor zaadwinning en veroorzaken daarbij embryoloosheid. Op 5 en 17 juli 1957 werd gespoten met 0,75% DDT en 0,2% Dieldrex 15. DDT bleek lange tijd de wantsenpopulatie sterk te drukken, terwijl dieldrin veel minder effectief bleek. Kiemproeven met het aldus behandelde en onbehandeld zaad toonden aan dat, waar de controleveldjes een kiemingspercentage gaven van 53%, dit op de DDT veldjes verhoogd was tot 89% en op de dieldrinveldjes tot 65%. Op de DDT-veldjes bleek ook het percentage slecht gekiemde zaden, te wijten aan schimmel- en bacterieaantasting na de kieming, in vergelijking met de controleveldjes sterk te zijn gedaald.
    Notes: Summary In a field experiment againstLygus campestris, attacking the young seeds of carrots cultivated for seed in North Holland, two treatments with an atomized spray of 0.75% DDT prevented an increase of the population of the bugs which started 18 days after the first treatment. Dieldrin-spray, 0.2% Dieldrex 15, had less effect. DDT raised the yield of the treated crop from 53 to 89 per cent., dieldrin from 53 to 65 per cent., estimated by counting the well-germinated seeds per plot.

    Description / Table of Contents: Samenvatting Onbehandelde rupsen vanEphestia kuehniella andPieris brassicae werden samengebracht met een aantal rupsen van dezelfde soort, die kort tevoren anaal, resp. oraal geïnfecteerd waren met een suspensie vanB. thuringiensis. Van de laatste categorie stierven de meeste na enkele dagen. Ofschoon de gezonde, zieke en dode rupsen daarna nog enige weken werden samengehouden, trad er onder de onbehandelde rupsen praktisch geen sterfte op, die veroorzaakt was door bacteriën.
    Notes: Abstract A number of untreated larvae ofEphestia kuehniella andPieris brassicae were confined with some larvae of the same species that had recently been infected withBacillus thuringiensis. The majority of the last category died within a few days. Although healthy, diseased and dead specimens were kept together for several days, scarcely any larva of the healthy group became diseased or died by the action of the bacterium. It was concluded thatB. thuringiensis does not spread easily.
