Peneid shrimp are commonly reared in clear-water aquaria or tanks for short-term studies of 4-6 weeks during controlled experiments, such as nutrition studies to estimate dietary nutrient requirements. Recently, in line with the genetic program at Centre Oceanologique du Pacifique (COP), experimental clear-water facilities were tested for the first time over a longer rearing period. Environmental conditions used to maintain animal growth in clear-water system using a well-balanced diet were defined. After 100 days, shrimp growth rates tended to decrease and only by adjusting the diet could shrimp complete their life cycle and reach maturation size of around 40 g. This paper presents information on stocking density, diet quality and husbandry linked to...

Autores: Cruywagen, E.M.; Beer, Z.W. de; Roux, J.; Wingfield, M.J.
Australia has efficient and visible plant quarantine measures, which through various border controls and survey activities attempt to prevent the entry of unwanted pests and diseases. The ability to successfully perform this task relies heavily on determining what pathogens are present and established in Australia as well as those pathogens that are exotic and threatening. There are detailed checklists and databases of fungal plant pathogens in Australia, compiled, in part, from surveys over many years sponsored by Federal and State programmes. These checklists and databases are mostly specimen-based, which enables validation of records with reference herbarium specimens and sometimes associated cultures. Most of the identifications have been based on...

Occurrence of Aceria tosichella in Brazil
Provedor de dados: 86
Autores: Pereira,Paulo Roberto Valle da Silva; Navia,Denise; Salvadori,José Roberto; Lau,Douglas.
The objective of this work was to evaluate the occurrence of Aceria tosichella Keifer (Prostigmata: Eriophyidae), the wheat curl mite, in Rio Grande do Sul, Brazil. Samples to detect A. tosichella specimens were collected in wheat, corn, oat crops and potential host grasses in 46 localities, in October 2006, August and October 2007. Samples of wheat were also collected in experimental greenhouses at Embrapa Trigo, Passo Fundo, RS, Brazil. A. tosichella specimens were found in wheat samples from Passo Fundo, Palmeira das Missões, São Luís Gonzaga, and Santo Antônio das Missões, RS, Brazil. Symptoms due to A. tosichella infestations were observed only in greenhouse conditions. This is the first report of A. tosichella in Brazil and the second in South America.

The Economics of Agricultural and Wildlife Smuggling
Provedor de dados: 31
Autores: Ferrier,   Peyton Michael.
The United States bans imports of certain agricultural and wildlife goods that can carry pathogens or diseases or whose harvest can threaten wildlife stocks or endanger species. Despite these bans, contraband is regularly uncovered in inspections of cargo containers and in domestic markets. This study characterizes the economic factors affecting agricultural and wildlife smuggling by drawing on inspection and interdiction data from USDA and the U.S. Fish and Wildlife Service and existing economic literature. Findings reveal that agricultural and wildlife smuggling primarily include luxury goods, ethnic foods, and specialty goods, such as traditional medicines. Incidents of detected smuggling are disproportionately higher for agricultural goods originating...

An Economic Analysis of Quarantine:  The Economies of Australia's Ban on New Zealand Apple Imports
Provedor de dados: 31
Autores: Arthur,   Matthew.
The quarantine policy decision-making process in Australia is subject to the principles of the World Trade Organisation's SPS Agreement. It is primarily based on the risks and associated economic costs accruing to producers in the event of disease entry. The costs of a quarantine measure in terms of forgone trade benefits are not considered. The impact associated with this asymmetric approach is identified by demonstrating the gains to consumers which may arise through liberalised markets using a case study of the Australian apple industry. A partial equilibrium analysis is used to show the impacts of apple market liberalisation, which can be expected to yield gains to consumers which are greater than the economic costs to on producers.

Welfare Impacts of the Mexico Potato Quarantine
Provedor de dados: 31
Autores: Richards,   Timothy J.; Molina,   Ignacio; Hussein,   Osman.
Under the North American Free Trade Agreement (NAFTA) tariffs on U.S. potato imports to Mexico were phased out by 1993. Citing phytosanitary issues, in 1996, the Mexican government placed quantitative restrictions on U.S. potato imports and restricted their import only to designated border areas. This article estimates the welfare cost of restricting U.S. potato imports into Mexico. We find that removing trade restrictions may lead to over 1.8 million tons of new imports into Mexico, a gain of consumer surplus of 4.0 billion pesos per year, and a loss of 2.9 billion pesos of producer surplus.

Defining the Costs of an Outbreak of Karnal Bunt of Wheat
Provedor de dados: 31
Autores: Brennan,   John P.; Thorne,   Fiona S.; Kelly,   Paul W.; Murray,   Gordon M.
In determining the economic impact of a possible outbreak of the quarantinable wheat disease Karnal Bunt, an examination was made of the detailed components of the costs involved. The costs were classified as: (a) Direct costs (yield and quality losses); (b) Reaction costs (export bans, quality down-grading, seed industry costs); and (c) Control costs (quarantine zones, fungicides, spore destruction). The relative importance of each of these cost components is measured for a hypothetical outbreak of Karnal Bunt in the European Union, as a means of ensuring that the policy responses to such an outbreak are appropriate considering the costs involved.

A Rapid and Reliable Method for Molecular Detection of Fusarium guttiforme, the Etiological Agent of Pineapple Fusariosis
Provedor de dados: 52
Autores: Carnielli-Queiroz,Lorena; Fernandes,Patricia Machado Bueno; Fernandes,Antônio Alberto Ribeiro; Ventura,José Aires.
Abstract Pineapple (Ananas comosus var. comosus) fusariosis is an economically important fungal disease affecting the plant and its fruit. A rapid and reliable diagnosis is the base of integrated disease management practices. Fusariosis has resulted in quarantines for pineapple products in Central America, Africa and Asia. Difficulties diagnosing and correctly identifying the fungus Fusarium guttiforme, agent of the pineapple fusariosis, have led to the search for new methodologies, and for this we developed a new reliable molecular method to detect it. For diagnostic purposes, real-time PCR of elongation factor gene 1-α (ef1) was used to rapidly, specifically and sensitively diagnose F. guttiforme. A pathogenicity test was conducted with slips of the...
