Pole detail, PNG Coffee Industry Board Office and Warehouse, Goroka

Detailed view of poles used in construction. Poles were spliced in their length with steel bars (like 3 pin plugs) and these joints were restrained from splitting with steel strap belts. The belts were tightened with opposing wedges like the old Greene & Greene wrought iron detail.

Wolbachia infection in the Coffee Berry Borer (Coleoptera: Scolytidae)

A nested polymerase chain reaction protocol yielded positive detection of the maternally inherited cytoplasmic proteobacterium Wolbachia in total genomic DNA from coffee berry borers collected in Benin, Brazil, Colombia, Ecuador, El Salvador, Honduras, India, Kenya, Mexico, Nicaragua, and Uganda. Wolbachia was not detected in specimens from Cameroon, the Dominican Republic, Indonesia, Jamaica, and Peru. Amplified bands from India and Brazil were cloned and sequenced. The 438-bp sequence clearly conformed to Wolbachia group B and was nearly identical to that of Ephestia kuehniella. The possible implications of Wolbachia infection in the coffee berry borer are discussed.

Pyruvated carrageenans from Solieria robusta and its adelphoparasite Tikvahiella candida

Solieria, the type genus of the commercially important red algal family Solieriaceae (Gigartinales), contains seven or eight species, three of which are represented in Australia. The cell-wall galactans of the most common Australian Solieria species, S. robusta (Greville) Kylin, were analysed by a combination of compositional assays, linkage analysis, and Fourier transform infrared (FTIR) and C-13 nuclear magnetic resonance (NMR) spectroscopy. They are shown to be composed predominantly of carrabiose 2,4'-disulphate units (the repeating unit of iota-carrageenan) and a significant proportion of 4',6'-pyruvated carrabiose 2-sulphate units. The constituent sugars, pyruvate content, FTIR spectrum, and linkage and substitution patterns of the galactans from Tikvahiella candida Kraft et Gabrielson, an adelphoparasite of Solieria robusta, closely resemble those of its host and furnish evidence in support of a close phylogenetic relationship between the two species.
