Pests have been a constant threat to agriculture the world over. In the Fiji Islands where the major agricultural export commodity is raw sugar, the Sugarcane weevil borer is one such agricultural pest that poses a real threat to an already ailing industry. The Sugarcane weevil borer (Rhabdoscelus obscure) is a pest originally found in Papua New Guinea whose introduction into Fiji has resulted in crop damage particularly to the soft variety of sugarcane found in Fiji. This review highlights the emergence of the weevil borer and explains a possible control that could be implemented by the Fijian farmers. The current method of control in Fiji uses the split billet trap. While this method has been recognized as an economically viable method of controlling the spread of the weevil borer, it has not been completely effective in eradicating the pest. This paper highlights and puts forth recommendations on other methods which could be used by the sugarcane industry.

Sugarcane Industry

Chemical ripening of sugarcane is an important component to profitable sugar production in the United States as well as other sugarcane industries throughout the world. Harvesting of sugarcane often begins before the sugarcane reaches the desirable maturity level. This is especially true in the Louisiana sugarcane industry where the window for harvesting is limited because of the risk of freezing temperatures encountered in a temperate climate. Research on the application of chemicals, mostly of herbicide origin, to enhance sucrose accumulation (ripening) or limit flowering to conserve stored sucrose has been conducted for more than 60 yr. The only sugarcane ripener currently registered for use in the United States is glyphosate applied before harvest. The herbicide fluazifop is used as the primary ripener of sugarcane in South Africa. The herbicides glyphosate, fluazifop, and sulfometuron-methyl and the growth regulators ethephon and trinexapac-ethyl are registered for use in Brazil. There is a continuing need to evaluate sugarcane ripeners to increase the utility of currently registered ripeners and to find additional ripeners for use by sugarcane industries. The need for alternatives to glyphosate is especially critical before a glyphosate-tolerant sugarcane can be utilized to improve control of problematic weeds.

The growing story of early settlement in the northwest Pacific islands is moving from coastal sites into the rainforest. Evidence of Pleistocene cultural layers have been discovered in open-site excavations at Yombon, an area containing shifting hamlets, in West New Britain's interior tropical rainforest. These sites, the oldest in New Britain, may presently stand as the oldest open sites discovered in rainforest anywhere in the world.

Dog cloning as a concept is no longer infeasible. Starting with Snuppy, the first cloned dog in the world, somatic cell nuclear transfer (SCNT) has been continuously developed and used for diverse purposes. In this article we summarise the current method for SCNT, the normality of cloned dogs and the application of dog cloning not only for personal reasons, but also for public purposes.

The 1998 Papua New Guinea tsunami was a significant puzzle for scientists who finally cracked the cause, but it also marks the most recent event of many that can be dated back to at least 6,000 years ago where the skull of the oldest tsunami victim in the world was found. Papua New Guinea was also the starting point for the most remarkable navigational feat in the world, with Polynesians moving rapidly east into the Pacific Ocean, their settlement of the region being punctuated by hiatuses caused by catastrophic tsunamis approximately 3,000, 2,000, and 600 years ago. It was on isolated Pacific islands that humans first came into contact with the deadly Pacific Ring of Fire. Settlement abandonment, mass graves, and cultural collapse mark their progress.

Genre Practices

This chapter focuses on a memoir and a film that narrate the experiences of Kurdish writer Behrouz Boochani in an Australian refugee camp in Papua New Guinea in order to show how genres organically develop out of human engagement with social and historical circumstances. The author discusses the novel and the film as examples of how writers' interactions with the world impose rhetorical orientations and nurture genre formation. This chapter illustrates that, as opposed to the dominant view of rhetoric as a means of persuasion, the essence of rhetoric and genre formation is engagement with what the author calls “phenomenological autoethnography.” The author argues that studying writing in times of crisis makes the phenomenological and autoethnographic foundations of writing visible because in crises rhetoric is unapologetically used to resist injustice and build resistance through “poetic realism,” which consists of fluid genre practices that can help capture the complexities of human experience.

An annotated checklist of the chondrichthyan fishes (sharks, rays, and chimaeras) of Papua New Guinean waters is herein presented. The checklist is the result of a large biodiversity study on the chondrichthyan fauna of Papua New Guinea between 2013 and 2017. The chondrichthyan fauna of Papua New Guinea has historically been very poorly known due to a lack of baseline information and limited deepwater exploration. A total of 131 species, comprising 36 families and 68 genera, were recorded. The most speciose families are the Carcharhinidae with 29 species and the Dasyatidae with 23 species. Verified voucher material from various biological collections around the world are provided, with a total of 687 lots recorded comprising 574 whole specimens, 128 sets of jaws and 21 sawfish rostra. This represents the first detailed, verified checklist of chondrichthyans from Papua New Guinean waters.

History Of

AbstractOriginally intended to provide an accessible overview for colleagues in Papua New Guinea, this article outlines the emergence of the continental division of the world in classical antiquity. In medieval Europe this survived as a learned conception which eventually acquired emotional content. Nevertheless, the division was still within the context of universal Christianity, which did not privilege any continent. Contrary to the views of recent critics, the European sense of world geography was not inherently ‘Eurocentric’. While Europeans did develop a sense of continental superiority, Americans, Africans, and many Asians also came to identify themselves with their continents and to use them as weapons against European domination. The application of the division to Melanesia is also considered.

Total Salinity

The Purari River in Papua (Papua New Guinea) is a tropical river with ionic dominance similar to that of the world average river water, i.e. Ca > Mg > Na > K, and HCO3 > (SO4?) > Cl. As the sulphate concentration was not determined, the anionic trend still needs to be further investigated. The Na:Ca as well as the Ca + Mg:Na + K ionic ratios suggest that chemical weathering in the highlands is the dominant source of dissolved solids, and that it determines the chemistry of the lower course of the Purari River. Among the waters investigated, the Purari River, in its lower course, has a total salinity higher than that of the Sirinumu impoundment, and lower than that of the Sepik River. The low concentration of solutes in the Sirinumu impoundment near Port Moresby indicates that oligotrophication can be expected in reservoirs built on Papuan rivers.
