The state of Rio Grande do Norte counts with a relevant potential in the shrimp farming supply chain. In the larviculture step the state responds for more than half of the national production. In the farming step it is the second largest producer. In the industrial step, its industries have almost 40% of the shrimp processing capacity of the northeast of Brazil. However, this country has the highest tax rate comparing with the main shrimp producer countries. Considering the influence of taxes in the competition among companies, the main goal of this research is to analyze the impact of indirect taxes in the above steps of the supply chain. To achieve it, it will be used the data of the 2011 Census of the Shrimp Farming and it will be applied the Herfindahl-Hirschman Index to identify the market form of those steps. In order to contribute with the characterization of the supply chain, CEO´s of farms and industries will be interviewed. The price-elasticity of the shrimp larvae, the in natura shrimp and the processed shrimp will be analyzed in order to verify the possibility that each one of those three steps has to pass-through the onus of the end of benefit over the ICMS. The data analysis shows that the larviculture step functions as a duopoly and, facing the end of that benefit, it will be able to pass-through most its onus to the farming step. On the other hand, this step functions similar to a perfect competing market, which diminishes its capacity to pass-through that onus to the processing step. This step operates as oligopoly with a lower concentration than the larviculture step but, due to the fact that it faces an oligopsony, it will end up assuming most of that onus, which will cause a decrease in the amount of processed shrimp. It is concluded that the end of that benefit would impact negatively, in this state, the supply chain at all, but mainly the farming and the industrial steps

Redescription of adult and larva of Colasposoma sellaturn Baly (Coleoptera: Chrysomelidae: Eumolpinae): a pest of sweet potato in Australia

The genus Colasposorna Laporte is shown to be represented in Australia by a single species, C. sellaturn Baly (= C. barbaturn Harold, syn. conf.; = C. regulare Jacoby, syn. nov.). The adult and larva are described and lectotypes designated for C. sellaturn and C. regulare. Colasposoma sellaturn is recorded from the Northern Territory, northern Queensland and New Guinea. This species is a pest of Ipomoea batatas (sweet potato) in northern Queensland, where the adults damage stems and foliage and larvae may cause considerable damage to tubers. Its pest status is assessed and control measures discussed.

Inclusión de la harina de larva de mosca doméstica (Musca doméstica) en la dieta de pollos de engorde

El presente trabajo experimental "Inclusión de harina de Larva de Mosca Doméstica (Musca domestica) en la dieta de pollos de engorde, es un estudio que se efectuó en El Instituto Politécnico Agroindustrial del Norte (IPADEN) "Naciones Unidas", ubicado en el kilómetro 114 1/2 carretera panamericana, (San Isidro, Matagalpa) por un periodo de siete meses. Este se desarrollo en dos etapas: 1. Producción de larva de mosca doméstica, donde se obtuvo una producción d 13.202 Kg de harina de larva de mosca seca, obtenida de una producción aproximada de 24.23 g de harina de larva de mosca seca (promedio) por Kg de estiércol de cerdo, aportando el 60.93% de proteína bruta. 2- inclusión de la harina de larva de mosca doméstica seca en la dieta de pollos, llevándose a cabo por un periodo de seis semanas. En el estudio se evaluaron dos tratamientos TI 16.34% de inclusión de HMLS y T2 0% de inclusión de HMLS, donde le utilizaron 56 pollos de engorde, sin sexar ( Mixtos ) ,de la línea Petter Hubbard de un día de edad y con un promedio de 60 g. Cada tratamiento estuvo conformado por cuatro repeticiones y 7 Pollos por cada repetición. El análisis estadístico empleado fue el Diseño Completamente al Azar (DCA) donde se evaluaron las variables, Consumo, ganancia media diaria, conversión alimenticia y peso vivo final, obteniendo una GMD de 31.63 g y 23.96 g. no encontrando diferencia significativa al P>0.05 respectivamente, además se constató una utilidad económica de los tratamientos donde el T2 obtuvo la mejor utilidad con respecto al Tl.
