A multiple alignment of the capside protein sequences of nepoviruses and comoviruses suggests a common structure Inra
Le Gall; Candresse, T.; Dunez, J..
The amino acid sequences of the regions encoding the structural proteins of eleven nepoviruses and five comoviruses, two genera of the familyComoviridae, have been aligned. The properties predicted by computer analysis (three-dimensional-3D-structure, hydrophobicity) are also correlated along this alignment, and aligned to the experimentally determined 3D structure of two comoviruses. It can thus be assumed that the 3D structure of the unique nepovirus coat protein matches that of the bipartite protomer found in the comovirus particles. In this model, the spatial locations of two amino-acid motifs characteristic of nepoviruses are in close vicinity, at the external surface of the virion. The coat proteins of nepoviruses and comoviruses may thus share a...

A NEW ALGORITHM FOR COMPUTING COMPENSATED INCOME FROM ORDINARY DEMAND FUNCTIONS AgEcon
Dumagan, Jesus C.; Mount, Timothy D..
This paper proposes a REversible Second-ORder Taylor (RESORT) expansion of the expenditure function to compute compensated income from ordinary demand functions as an alternative to the algorithm proposed by Vartia. These algorithms provide measures of Hicksian welfare changes and Konus-type cost of living indices. RESORT also validates the results by checking the matrix of compensated price effects. obtained through the Slutsky equation, for symmetry and negative semi-definiteness as required by expenditure minimization. In contrast, Vartia's algorithm provides no validation procedure. RESORT is similar to Vartia's algorithm in using price steps. It computes compensated income at each step "forward" from the initial to the terminal prices, and insures...

A new classification of the Cestode order Proteocephalidea Mola Zoologia
Rego,Amilcar Arandas.
The morphology, ontogeny, life-cycles and distribution of species of the Order Proteocephalidea (Cestoda), is discussed. A brief historic of the classifications is presented. The actual scheme of taxonomy of WOODLAND (1924-1935) is criticicized and a new classification for the group is proposed. The phylogenetic uniformity of Proteocephalideans is reestablished with this classification. The genera of Monticelliidae (sensu Woodland) are transferred to the subfamilies Proteocephalinae and Corallobothriinae. Only one family is accepted in the Proteocephalidea. Proteocephalidae La Rue. 1911: with five subfamilies: Proteocephalinae. Corallobothriinae. Sandonelliinae. Gangesiinae and Acanthotaeniinae.

A new interstitial species of Gammarella (Amphipoda, Gammaridea) from the western Mediterranean Sea Naturalis
Martí, Amparo; Villora-Moreno, Santiago.
A new species of Gammarella Bate, 1857 is described from shallow water, inhabiting the interstitial system in soft bottoms of the Chafarinas Archipelago (western Mediterranean, N. Africa). The relationships of Gammarella with the genera Nuuanu and Cottesloe are briefly discussed. Numerical taxonomie methods are utilized to differentiate between the morphologically related species and the intermediate species. In a table the principal differentiating characters of Gammarella species are presented. Gammarella garciai n. sp. is characterized by its intermediate position between Gammarella, Nuuanu and Cottesloe, showing an intergradation of characters. Gammarella garciai n. sp. and G. merringannee show ecologically intermediate characters between the larger...

A new RNA picorna-like virus in the cotton pink bollworm Pectinophora gossypiella (Lep. : Gelechiidae) in Egypt IRD
Monsarrat, Annie; Abol-Ela, S.; Abdel-Hamid, I.; Fédière, Gilles; Kuhl, G.; El Husseini, M.; Giannotti, J..
Un nouveau virus infectant le ver rose du cotonnier, #Pectinophora gossypiella$, a été isolé et purifié à partir de larves mortes récoltées en champ de coton. Les virions purifiés de 27 plus ou moins 1 nm de diamètre, ont une forme icosaédrique et contiennent un génome à ARN. Trois protéines capsidaires de 31,7, 32,6 et 47,4 Kd ont été trouvées dans les virions. Le virus purifié n'est pas hautement infectieux pour les larves, cependant la durée du stade chrysalide est supérieure chez les lots infectés artificiellement. Dans les tissus atteints, les virions sont dispersés dans le cytoplasme des cellules de l'intestin ou bien groupés en amas paracristallins de même type que chez d'autres insectes infectés avec des picornavirus. Les adultes malades...

A new sampling method for freshwater shrimps IRD
Fossati, Odile; Danigo, Anne-Hélène.
Les peuplements de #Macrobrachium$ (#Palaemonidae$, #Decapoda$, #Crustacea$) ont été étudiés dans l'île de Nuku-Hiva (Polynésie française) à l'aide de petites nasses faites à partir de bouteilles d'eau minérale. Différentes expériences ont été réalisées pour tester l'effet de la densité des nasses dans une vasque, l'effet de la durée d'échantillonnage, et pour essayer d'estimer la sélectivité des nasses en terme d'espèce et de taille. Aucune relation n'est apparue entre le nombre de crustacés capturés et la densité des nasses ou la durée de la capture. La principale limitation de cette méthode de capture passive apparaît liée à la taille des individus. L'efficacité de l'échantillonnnage a été estimé à environ 50%. (Résumé d'auteur)

A new species of Lopaphus Westwood, described from Borneo (Insecta: Phasmida: Heteronemiidae: Necrosciinae) Naturalis
Bragg, P.E..
The genus Lopaphus is recorded from Borneo for the first time. The species, L. borneensis spec. nov. is described from a series of seven males and five females which were collected in Kalimantan in 1925, two specimens from Sabah, a female collected in 1986 and a male in 1987, and a male which was collected by the author in Brunei in 1991. The female resembles L. brachypterus (de Haan) but is more slender and is readily distinguished by the shape of the mesonotum. The male, female and egg are all illustrated. A modification of Redtenbacher's key to the genus is provided.

A niche marketing guide for lamb cooperatives AgEcon
Kazmierczak, Tamra Kirkpatrick; Bell, James B..
The two types of niche markets targeted by lamb marketing cooperatives are described in this guide. The first type includes specialty middlemen outlets that cooperatives used to market lamb to specialized niches within the traditional meat marketing system of retail food stores, restaurants, food service outlets, and specialty distributors. The second type includes those outlets that cooperatives used to market lamb directly to the consumer, such as freezer markets, farmers' markets, mobile markets, and mail order sales. This guide also describes the advertising, promotional, and other marketing programs used by cooperatives to target these markets. Finally the competition, product differentiation, capital requirements, market development, management,...

A NOTE: A CLARIFICATION OF THE ROLE OF YIELD UNCERTAINTY IN INFLUENCING OVER-QUOTA PRODUCTION AgEcon
Fraser, Rob W..
The literature shows that the influence of yield uncertainty on production relative to quota is ambiguous in the case of a single market. This paper uses a two-market framework (quota market and secondary market) with multiplicative yield uncertainty to show that if over-quota production in the absence of yield uncertainty is profitable, then the presence of yield uncertainty is unambiguously a further stimulus to over-quota production. The analysis is discussed in the context of recent changes to the marketing arrangements for Western Australian potatoes.

A Note on Accelerated Depreciation and Investment Allowances AgEcon
Douglas, Robert A.; Peterson, Deborah C.; Kokic, Philip; Parameswaran, Bhamathy.
Accelerated depreciation and investment allowances are frequently requested by industry as a means of encouraging investment and promoting the adoption of socially desirable practices by farmers. Examples include the 100 per cent tax deduction for capital expenditure to combat and prevent land degradation (Section 750), and the recently introduced 10 per cent investment allowance for fodder and water storage for livestock, water conveyancing and minimum tillage equipment. Farm level survey data are used to provide evidence of the extent and distribution of benefits to farmers that flow from different rates of depreciation, and from the introduction of a 10 per cent investment allowance. A priori, it may be difficult for the farmer (or farm financial...
