    The influence of soil factors on the growth of a grass/clover sward on a restored opencast site in Northumberland, UK (1994)

    Notes: The growth of grass and clover components in mixed swards on a site restored after opencast coal mining and an undisturbed control site were compared. Soil nitrogen supply was reduced at the restored site. This inhibited grass growth but was beneficial for the clover component.Growth at the restored site was also inhibited by a compacted subsoil, which reduced available soil water content and impeded access to available soil water. This inhibited crop production from the middle of the second silage crop onwards. In 1989 this was associated with the soil at the restored site reaching permanent wilting point at 40cm. In 1990 this effect was associated with the restored site soil reaching permanent wilting point at 70cm. These drought effects reduced clover growing point population and stolon mass. Grass tiller populations were unaffected.

    Monophagy in a polyphagous grasshopper,Schistocerca shoshone (1994)

    Notes: Abstract The feeding behavior of different populations of the grasshopper,Schistocerca shoshone, was investigated in the southwestern United States. Insects from three riparian populations, with a broad spectrum of plants available to them, tended to eat plants roughly in relation to their availability except that broad-leaved herbaceous plants were avoided. Insects from a desert population in a plantation ofSimmondsia fed exclusively on that plant, as did those from another population in the Tucson mountains, despite the availability of a range of other plants. Insects from a third desert population, near Portal, fed mainly onProsopis, the dominant woody plant. In detailed behavioral experiments in the laboratory, insects from Tucson mountains readily acceptedSimmondsia, and less readily acceptedProsopis. Three other common woody plants from the habitat were generally rejected without feeding. Insects from Portal acceptedProsopis andSimmondsia with approximately equal readiness. Breeding experiments suggested that the differences between the plantation insects and those from Portal was genetic and not induced by experience. The insects from both populations were potentially polyphagous and ate a wide range of plants in the laboratory if given no alternative.

    Effects of fluvalinate on two-spotted spider mite dispersal, fecundity and feeding (1994)

    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.

    Meal size in nymphs of Locusta migratoria (1972)

    Description / Table of Contents: Zusammenfassung Die Nahrungsmenge, die von einer Larve der Wanderheuschrecke, Locusta migratoria L., im fünften Entwicklungsstadium bei einer einzigen Mahlzeit verzehrt wird, wurde ermittelt, indem ihr Darm und Darminhalt sofort nach dem Fressen gewogen wurden. In der Mitte des Entwicklungsstadiums wurden größere Mengen verzehrt, Weibchen fraßen mehr als Männchen, jedoch sind die weiblichen Larven ja auch größer. Die Menge der aufgenommenen Nahrung vergrößerte sich mit der Dauer künstlichen Futterentzuges. Sie erreichte ihren Höhepunkt nach sechs Stunden, nach welcher Zeit der Vorderdarm absolut leer war. Die verzehrten Mengen waren je nach der Art der Nahrung unterschiedlich. Auch stellten die Insekten sich so ein, daß sie von einer bestimmten Nahrung mehr zu sich nahmen, wenn sie daran aufgezogen worden waren. Nach längeren Zeitspannen der Isolierung hatten sie die Tendenz, weniger zu fressen. Temperatur und Feuchtigkeit hatten keinen Einfluß auf die Mengen, die verzehrt wurden, außer bei 40°, bei welcher Temperatur sich das gesamte Verhalten zum Fressen ändert.
    Notes: Abstract Meal size in fifth-instar nymphs of Locusta migratoria L. has been investigated by weighing the gut and its contents immediately after feeding. Larger meals are taken in mid-instar, while females eat more in one meal than males under the same conditions. Bigger meals are also eaten after longer periods of food deprivation, but after deprivation for two hours or less, corresponding with the normal interfeed length, meals are smaller than would be expected from the potential maximum foregut volume. The maximum volume attained varies with the type of food available to the insects and is influenced by previous conditioning. Temperature and humidity do not affect meal size except at 40°, at which temperature the usual pattern of feeding is completely altered.

    The relationship between plant acceptability and suitability for survival and development of the polyphagous grasshopper,Schistocerca americana (Orthoptera: Acrididae) (1994)

    Notes: Abstract The feeding behavior of final-instar nymphs ofSchistocerca americana was observed when they first encountered plants that ranged in acceptability from being eaten in large amounts to not being eaten at all. Growth and survival on the same plants through the last stadium were also studied and the results combined as a suitability index to facilitate comparison with the behavior. Although the plants that were eaten most gave the highest suitability index and those that were not eaten permitted no survival, there was no simple relationship between the amounts eaten and the suitability for growth and survival. The possibility that the insects might become habituated to plants that were initially unacceptable was investigated, but no habituation was found over a 3-day period. It is suggested that food intake is largely determined by the presence of deterrent compounds in the less acceptable foods and that nutritional differences between the plants are likely to have been of minor importance. The behavior on some foods suggests that food aversion learning may be involved. It is concluded that the variability of the insects' behavior makes it impossible to predict the suitability of a plant from their immediate behavioral responses. In the field, insects may sometimes reject foods that would be suitable for survival and development, and feed on plants that are nutritionally deficient or even toxic.
