    Interactions between two neurons in contact chemosensilla of the grasshopper, Schistocerca americana (1990)

    Notizen: Summary The tibial contact chemosensilla of Schistocerca americana contain several neurons, one of which responds to nicotine hydrogen tartrate and certain other compounds. The activity of this cell is sometimes briefly interrupted by the firing of a second cell in the same sensillum which usually only fires a few times in the first 500 ms of a stimulation. The evidence suggests that the nicotine-sensitive cell is directly inhibited by the activity of the second cell. Not all cells in the sensillum produce the same effect.

    Attraction and repulsion of the aphid,Cavariella aegopodii, by Plant Odors (1981)
    Springer
    Journal of chemical ecology 7 (1981), S. 881-888 
    Details
    ISSN: 1573-1561
    Schlagwort(e): Aphid ; Cavariella aegopodii ; Homoptera ; Aphididae ; plant odor ; carvone ; attractant ; repellent ; host-finding
    Quelle: Springer Online Journal Archives 1860-2000
    Thema: Biologie , Chemie und Pharmazie
    Notizen: Abstract Cavariella aegopodii is induced to land on traps by the monoterpene carvone, and the relevance of this to host-finding by the aphid is discussed. Catches are reduced by linalool. The interaction of plant chemicals in natural communities is discussed, and the possibility of using repellent chemicals for crop protection is suggested.

    The structure of the terminal sensilla on the maxillary palps of Locusta migratoria (L.), and changes associated with moulting (1971)
    Springer
    Cell & tissue research 121 (1971), S. 48-68 
    Details
    ISSN: 1432-0878

    Notizen: Summary The basic structure of the terminal sensilla of Locusta migratoria resembles that of Schistocerca gregaria. There are commonly six or ten neurons whose dendrites extend almost to the opening of the peg. Proximally the dendrites are clothed by a neurilemma cell which also encloses a basal cavity through which their ciliary region passes. The tormogen cell encloses the receptor-lymph cavity and actively secretes material into it. The receptor-lymph cavity and the basal cavity are quite separate. The development of new pegs at a moult is described. After apolysis the scolopale extends across the subcuticular space and protects the dendrites, which remain in a functional condition until shortly before ecdysis. As the trichogen cell grows out to form a new peg the tip is surrounded by a mass of electron-dense material, probably derived from the receptorlymph cavity. The function of this material is unknown. Regeneration of the dendrites is considered. The possible mechanism by which the tip of the peg opens and closes is considered and the general structure of the organule is discussed in relation to functioning.
