    Notes: [Auszug] FLYING swarms of locusts often cannot be effectively attacked from the air because of the danger to the aircraft. Attention is therefore focused on the circumstances in which a swarm will remain on the ground. In Kenya the desert locust, Schistocerca gregaria (Forsk.), roosts overnight in trees ...

    Notes: [Auszug] WHEN writing the book referred to by Dr. Kennedy, we were frequently faced with the alternatives of inventing new technical terms (which are often resented by the people who have to learn and use them) and of using common words in newly defined ways (which causes trouble because it is difficult ...

    Notes: [Auszug] A search of published information and local records regarding two outbreak regions of the red locust, the Mweru wa Ntipa in Northern Rhodesia and the Rukwa Valley in Tanganyika, suggested that wet periods of years were always unfavourable to locust numbers and dry periods were sometimes ...

    Notes: [Auszug] THE most commonly effective method of destroying locusts at present is to poison the hoppers (nymphs) before they can fly. Some kind of bait, such as moistened bran, which is eaten in preference to other food, is poisoned with benzene hexachloride (hexachlorocyclohexane, 'Gammexane', 'Benhex') and ...

    The temperature and humidity relations of the cockroach (Blatta orientalis) (1934)
    Springer
    Journal of comparative physiology 20 (1934), S. 617-625 
    Details
    ISSN: 1432-1351
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology , Medicine
    Notes: Summary 1. An apparatus is described in which a steady temperature gradient can be maintained and in which conditions of temperature and humidity can be accurately measured. 2. The preferred temperature range (indifference zone) of normal adult male Blatta orientalis in this apparatus is 20–29 ° C. 3. The indifference zone is not altered by changes in the humidity of the air. 4. Specimens desiccated to 70% of their original weight show a much lower preferred temperature, namely 12–23 ° C. 5. This is interpreted as a reaction to a gradient of saturation deficiency, an avoiding reaction against air of higher evaporating power.

    Notes: [Auszug] IT has been shown by Ullyott1 that the aggregation reaction of the flatworm, Dendroccelum lacteum, in a gradient of light intensities, can be described in terms of the rate of change of direction and the process of sensory adaptation in the eyes. This reaction has since been ...

    Notes: [Auszug] MR. YAPP'S communication on this subject1 is of considerable interest because it suggests that temperature may be a more suitable stimulus than pH for making a quantitative investigation of klino-kinesis in Paramecium. A quantitative study is required to discover how completely ...

    Notes: [Auszug] Western and Van Praet cite evidence for synchronous changes in levels of lakes over a large area of East Africa, especially in those lakes that have no outlet to the sea; Rukwa is one of those lakes2 and evidence from Lake Rukwa may be appropriate in the Maasi Ambolesi. Rainfall or lake levels of ...

    Notes: [Auszug] SIR,-Some say that propaganda induces people to believe statements that are not rationally convincing. A. H. Macpherson(Nature, 237, 413; 1972) writes that ?persistent pesticides are believed? to be responsible for the nearly complete disappearance of the peregrine falcon. This is the theme of much ...
