As an ambrosia beetle, it has developed its effective drilling mouthpart enough to make tunnels in hardwood of the tree. The fine structural aspects of the mouthpart using the field emission scanning electron microscopy are analyzed about 23 adults collected in galleries of infested cork oak trees (Quercus suber) in a littoral forest of northwest Algeria. These adults are preserved in alcohol 70%, cleaned and coated with gold. The mouthparts of this beetle consist commonly of a labrum, a pair of mandibles, a pair of maxillae and the labium but with adapted structure to excavate galleries in the hardwood. In this role is also involved the first pair of legs. The function that present the different structures related to the construction of the tunnels is discussed. Both of maxillary and labial palpi direct the food to the mouth and hold it while the mandibles chew the food. The distal ends of these palpi are flattened and have shovel-like setae. Females have larger maxillary palpi than males and this is related to the particular biology of each sex.</style></abstract></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Inácio, Maria Lurdes</style></author><author><style face="normal" font="default" size="100%">Henriques, Joana</style></author><author><style face="normal" font="default" size="100%">Lima, Arlindo</style></author><author><style face="normal" font="default" size="100%">Sousa, Edmundo</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Fungi of Raffaelea genus ( Ascomycota : Ophiostomatales ) associated to Platypus Cylindrus ( Coleoptera : Platypodidae ) in Portugal</style></title><secondary-title><style face="normal" font="default" size="100%">Revista de Ciências Agrárias</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">Ambrosia beetle</style></keyword><keyword><style  face="normal" font="default" size="100%">ambrosia fun- gi</style></keyword><keyword><style  face="normal" font="default" size="100%">Cork oak</style></keyword><keyword><style  face="normal" font="default" size="100%">decline</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">2008</style></year></dates><volume><style face="normal" font="default" size="100%">31</style></volume><pages><style face="normal" font="default" size="100%">96-104</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">In the study of the fungi associated to Platypus cylindrus, several fungi were isolated from the insect and its galleries in cork oak, among which three species of Raffaelea. Morphological and cultural characteristics, sensitivity to cycloheximide and genetic variability had been evaluated in a set of isolates of this genus. On this basis R. ambrosiae and R. montetyi were identified and a third taxon segregated witch differs in morphological and molecular characteristics from the previous ones. In this work we present and discuss the parameters that allow the identification of specimens of the three taxa. The role that those ambrosia fungi can have in the cork oak decline is also discussed taking into account that Ophiostomatales fungi are pathogens of great importance in trees, namely in species of the genus Quercus.</style></abstract></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Henriques, Joana</style></author><author><style face="normal" font="default" size="100%">INÁCIO, MARIA D E LURDES</style></author><author><style face="normal" font="default" size="100%">Sousa, Edmundo</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">FUNGI ASSOCIATED TO PLATYPUS CYLINDRUS FAB .

It is an ambrosia beetle that establishes complex symbioses with fungi whose role in the insect-fungus-host interaction has not been completely clarified. In order to characterize P. cylindrus associated micoflora in Portugal, fungi were isolated from different beetle organs and from its galleries in cork oak trees. Fungi of the genera Acremonium, Aspergillus, Beauveria, Botrytis, Chaetomium, Fusarium, Geotrichum, Gliocladium, Nodulisporium, Paecilomyces, Penicillium, Raffaelea, Scytalidium, Trichoderma and of the order Mucorales were identified. An actinomycete of the genus Streptomyces was also identified. Some of these genera were related for the first time to this interaction. In the present work the isolated fungi are characterized and their contribution for beetle population establishment and tree weakness is discussed.</style></abstract></record></records></xml>
