Der Bananenrüßler Cosmopolites sordidus (Germar) hat sich in weiten Teilen Afrikas zum wichtigsten Schädling der Banane (Musa spp.) entwickelt. - Der männliche Geschlechtsapparat von C. sordidus besteht aus Hoden, Vasa deferentia, Vesicula seminales, paarigen akzessorischen Drüsen, Ductus ejaculatorius und Aedeagus. Alle Organe wurden beschrieben und mit Figuren dargestellt. Das Sekret der paarigen akzessorischen Drüsen und der Vasa deferentia besteht aus Proteinen. Die Proteinkonzentration der akzessorischen Drüsen wurde photometrisch bestimmt.StichwörterColeoptera, Curculionidae, banana weevil, Cosmopolites sordidus, internal genitalia.

AbstractThe effects of host and non-host plant odours on the foraging responses of the banana weevil, Cosmopolites sordidus (Germar), were investigated in the laboratory through arena and olfactometer bioassays. Contrary to previous reports that banana rhizome and pseudostem were the most attractive parts to the weevil, dead leaves were most preferred. Comparison of dead banana leaves with dead leaves of other plants showed that attractant odours were present in yam, cocoyam and dead grasses but absent in cocoa and soybean leaves. Complete leaf senescence while the leaf was attached to the mother plant proved necessary for the development of the dead-leaf-based odours but the involvement of microbial organisms could not be demonstrated. It is possible that dead-leaf-based attractants could be used in combination with microbials such as entomogenous fungi and nematodes in integrated management of C. sordidus.
