    Notes: Abstract Chamaecytisus proliferus (L.fil.) Link (Fabaceae: Genisteae) represents a species complex in the Canary Islands. Floristic data from 147 releves from the whole complex were collected and analysed by classification (TWINSPAN) and ordination (DECORANA) methods. Results indicate that white escobon of Tenerife, escobon of El Hierro, white escobon of Gran Canaria and typical tagasaste in La Palma are associated with those plant communities from the north of these islands which are under the influence of the north-eastern trade winds. Narrow-leaved escobon in Tenerife and La Gomera, escobon of southern Gran Canaria and white tagasaste of La Palma are found in those areas which are not under the direct influence of these winds. Morphological forms from the more easterly islands (Gran Canaria and Tenerife-La Gomera) have the broadest ecological range and they have played an important role in the floristic changes which have taken place after the destruction of the forests in these islands. The highest priorities for in situ conservation should be given to wild populations of typical tagasaste, white escobon of Tenerife and escobon of El Hierro.

    Genetic resource conservation of the endemic genus Argyranthemum Sch. Bip. (Asteraceae: Anthemideae) in the Macaronesian Islands (1996)

    Notes: Abstract Germplasm from one or more populations of each taxon of the Macaronesian endemic genus Argyranthemum Sch. Bip. (Asteraceae: Anthemideae) was collected in the Canary Islands, Madeira, the Selvagens Islands and the Desertas Islands. A total of 253 germplasm samples was collected and they are conserved ex situ at the seed bank of Centro de Investigación y Tecnología Agraria de Canarias (Tenerife, Canary Islands, Spain). Duplicates are held at the germplasm bank of Escuela Técnica Superior de Ingenieros Agrónomos (Madrid, Spain). A preliminary account of the ecogeography of the genus based on field observation is provided. In situ conservation strategies are discussed, particularly with regard to the occurrence of hybridization within Argyranthemum.

    Free amino acid and protein titers inAnthonomus grandis larvae venomized byBracon mellitor (1993)

    Description / Table of Contents: Résumé Les fluctuations du niveau d'acides aminés libres ont été suivies dans des extraits de larves entières du troisième stade d'Anthonomus grandis Boheman (Curculionidae) ayant été piquées une fois par une femelle de l'ectoparasitoïdeBracon mellitor Say (Braconidae). Après la piqûre, le niveau d'acides aminés des larves a d'abord augmenté durant les 6 min suivant l'injection du venin, puis diminué dans les deux heures suivantes. Un second pic d'acides aminés est apparu 4 jours après la piqûre. Les augmentations observées dans le niveau d'acides aminés libres ont toujours été accompagnées par des diminutions synchrones de la quantité totale de protéines solubles. Un possible effet physiologique de l'injection du venin de l'ectoparasitoïde sur la régulation de la nutrition de l'insecte hôte est discuté.
    Notes: Abstract Changes in the free amino acid levels of extracts from body whole homogenates of 3rd instar boll weevilAnthonomus grandis Boheman (Curculionidae) larvae which had been stung once by females of the ectoparasitoidBracon mellitor Say (Braconidae) were determined. Stung larvae exhibited an initial rise in free amino acid levels within 6 min after the venom was injected followed by a decline within 2h. A second free amino acid peak occurred 4 days after initial sting. Observed increases in free amino acid levels were always followed by synchronized decreases in total soluble proteins. The possible nutritional regulatory effect of ectoparasitoid venom on the physiology of the boll weevil is discussed.
