Electron microscopical studies reveal that the phasmids of Scutellonema brachyurum include socket and sheath cells which appear to be secretory. The phasmid includes an external cup-shaped ampulla filled with electron-dense material which may be lipopolysaccharide. The ampulla is continuous, with a receptor cavity surrounded by the socket and sheath cells. The dendrite receptor originates from ...

The bark beetle Scolytogenes birosimensis Niijima is suspected to be involved in the decline of Pittosporum tobira (Thunb. ex Murray) Aiton in the coastal areas of Japan. We isolated fungi from adult S. birosimensis in nine different localities in Japan to assess their potential association and predict their contribution to the success of the beetle. Results from morphological identification o...

Objectives: The main objective of this study was to identify some yam assessions that are tolerant to the most invasive nematodes like Scutellonema bradys and Meloidogyne spp. Methodology and results: New assessions of Dioscorea spp. were screened in the savanna zone of central Côte d’Ivoire. Fourteen of D. alata and thirty seven assessions of D. rotundata were tested respectively and separatel...

Hazelnut, a very important cash crop in Turkey, is frequently colonized by bark and ambrosia beetle species (Scolytinae). Some scolytine species may cause economic damage while other species do not; therefore, proper identification is important in orchard management. Extensive sampling demonstrated that the most common pest species in Turkey's hazelnut orchards are Anisandrus dispar, Xylosandru...

This paper launches an open access DNA barcoding project "AUSBS" under the Barcoding of Life Datasystems (BOLD). The aims of the project are to help scientists who lack the necessary morphological knowledge to identify known species using molecular markers, to aid native bee specialists with the recognition of species groups that morphologically are difficult to define, and, eventually, to assi...

Location or stock-specific landing data are necessary to improve management of shark stocks, especially those imperiled by overexploitation as a result of the international shark fin trade. In the current absence of catch monitoring directly at extraction sites, genetic stock identification of fins collected from major market supply chain endpoints offers an overlooked but potentially useful ap...
