Abstract This paper analyzes the Australia – Anti-Dumping Measures on A4 Copy Paper panel report, the second recent WTO dispute to involve a challenge to Indonesia's paper industry. The Indonesian paper industry benefits from reduced-cost inputs because of the Indonesian government's influence and subsidies over the timber and pulp market. The report offers the first interpretation of ‘particular market situation’ under Article 2.2 of the WTO's Anti-Dumping Agreement. At the same time, it raises questions regarding the appropriateness of using anti-dumping measures to address what are fundamentally subsidy issues. While the panel ultimately found that Australia's measure was inconsistent with Article 2.2, the paper shows that the panel's interpretation of ‘particular market situation’ increases the relative attractiveness of using anti-dumping duties instead of countervailing measures. Two key points on the welfare implications of the decision can be made. The first relates to the motivations of the Australian paper industry and the imperfectly competitive market in which Australian Paper operates. The second is the importance of challenging subsidies rather than imposing anti-dumping duties where the subsidies in question have negative environmental effects.

Relative Attractiveness

AbstractDrosophila suzukii flies cause economic losses to fruit crops globally. Previous work shows various Drosophila species are attracted to volatile metabolites produced by individual fruit associated yeast isolates, but fruits naturally harbour a rich diversity of yeast species. Here, we report the relative attractiveness of D. suzukii to yeasts presented individually or in combinations using laboratory preference tests and field trapping data. Laboratory trials revealed four of 12 single yeast isolates were attractive to D. suzukii, of which Metschnikowia pulcherrima and Hanseniaspora uvarum were also attractive in field trials. Four out of 10 yeast combinations involving Candida zemplinina, Pichia pijperi, M. pulcherrima and H. uvarum were attractive in the laboratory. Whilst a combination of M. pulcherrima + H. uvarum trapped the greatest number of D. suzukii in the field, the efficacy of the M. pulcherrima + H. uvarum combination to trap D. suzukii was not significantly greater than traps primed with volatiles from only H. uvarum. While volatiles from isolates of M. pulcherrima and H. uvarum show promise as baits for D. suzukii, further research is needed to ascertain how and why flies are attracted to certain baits to optimise control efficacy.

Tephritid Fruit Flies

AbstractUnderstanding factors that influence attraction of tephritid fruit flies (Diptera: Tephritidae) to objects can lead to development of more sensitive traps for fly detection. Here, the objective was to determine if differences in attractiveness between two sticky yellow rectangle traps to western cherry fruit fly,Rhagoletis indifferensCurran, depend on ambient light intensity and direction. The translucent plastic Yellow Sticky Strip (YSS) was compared with the less translucent yellow cardboard Alpha Scents (AS). Flies were released inside a box or cage opposite a trap or traps illuminated from outside at different intensities to generate variable light passage. Regardless of type, the trap with greatest light passage was most attractive. When the same light intensity was shone on both traps, the YSS, which allowed greater light passage, was more attractive than the AS. When the light was inside a cage and shone onto the two traps in the same direction as approaching flies, the AS reflected more light and was more attractive. A field experiment generally supported light passage effects seen in the laboratory. Results suggest trap placement with respect to sunlight intensity and direction affects light passage and the attractiveness of yellow traps toR. indifferens.
