At least two indigenous species of the Bemisia tabaci complex are present in Brazil

Bemisia tabaci is one of the most important global agricultural insect pests, being a vector of emerging plant viruses such as begomoviruses and criniviruses that cause serious problems in many countries. Although knowledge of the genetic diversity of B. tabaci populations is important for controlling this pest and understanding viral epidemics, limited information is available on this pest in Brazil. A survey was conducted in different locations of São Paulo and Mato Grosso states, and the phylogenetic relationships of B. tabaci individuals from 43 populations sampled from different hosts were analysed based on partial mitochondrial cytochrome oxidase 1 gene (mtCOI) sequences. According to the recently proposed classification of the B. tabaci complex, which employs the 3.5% mtCOI sequence divergence threshold for species demarcation, most of the specimens collected were found to belong to the Middle East-Asia Minor 1 species, which includes the invasive populations of the commonly known B biotype, within the Africa/Middle East/Asia Minor high-level group. Three specimens collected from Solanun gilo and Ipomoea sp. were grouped together and could be classified in the New World species that includes the commonly known A biotype. However, six specimens collected from Euphorbia heterophylla, Xanthium cavanillesii and Glycine maxima could not be classified into any of the 28 previously proposed species, although according to the 11% mtCOI sequence divergence threshold, they belong to the New World high-level group. These specimens were classified into a new recently proposed species named New World 2 that includes populations from Argentina. Middle East-Asia Minor 1, New World and New World 2 were differentiated by RFLP analysis of the mtCOI gene using TaqI enzyme. Taq I analysis in silico also differentiates these from Mediterranean species, thus making this method a convenient tool to determine population dynamics, especially critical for monitoring the presence of this exotic pest in Brazil. © 2012 Blackwell Verlag, GmbH.

The Rights of Indigenous Children

While children in general are overrepresented among those living in poverty, a long history of discrimination and exclusion has ensured that indigenous children in Latin America and the Caribbean are in an even worse position. In the general population 63% of children aged under 18 years live in poverty, as measured by privation of the basic rights to well-being; however, that figure is as high as 88% among indigenous children in the same age group. This is a violation of these children's rights —including their rights to survival and development— and entails high costs for society in terms of productive capacity and social inclusion. That is the thrust of the argument in the central article of this issue of Challenges, which focuses on poverty among indigenous children. The data show a pattern of inequality that is highly detrimental to indigenous children: they make up a disproportionate number of those living in extreme poverty and are three times more likely to lack access to education, safe drinking water and housing than other children. It is a matter of particular concern that in the countries of the Andean Community 5 of every 10 indigenous children under the age of 5 years suffer from chronic malnutrition.This edition includes brief testimonies by indigenous children as to what their life is like; an interview with Marta Maurás, Vice-Chairperson of the United Nations Committee on the Rights of the Child, on the international mechanisms in place to safeguard the rights of indigenous children; and, lastly, an article on the Uantakua programme in Mexico, which uses information and communication technologies in bilingual schools with large indigenous populations.

Guaranteeing indigenous people's rights in Latin America. Progress in the past decade and remaining challenges. Summary

As the twenty-first century advances, the countries of Latin America are building deeper democracies and looking critically at the development process, in the growing conviction that development should focus on equality and be approached on the basis of rights. This means tackling the region’s persistent inequalities, especially those affecting indigenous peoples, who have historically suffered exclusion and discrimination. It also means guaranteeing indigenous people both the enjoyment of human rights on an equal footing to the rest of society, and the right to be collectively different. This is a challenge for this century, which began with the recognition of the rights of indigenous people and the role they unquestionably play on national and international agendas.

Larval development of indigenous South American freshwater fish species, with particular reference to pacu (Piaractus mesopotamicus): A review

In recent years, a number of South American freshwater fish have gained increasing attention for their potential in aquaculture, not only because of their excellent performance in farming systems but also to meet the high consumer demand for these species due to declining fishery resources. Many South American freshwater species are migratory and produce altricial larvae, with a small amount of yolk reserves. Unlike precocial freshwater species and altricial coldwater marine fish, these freshwater fish investigated have rapid yolk depletion and metamorphosis. Specific studies on the initial development of South American fish are scarce and fragmented. One of the most widely studied species is the pacu (Piaractus mesopotamicus), farmed in warm continental waters. In the present review we compile new and published data on the initial development of pacu, including morphogenesis of the skeletal, muscle, digestive and sensory systems; compare it to other Neotropical species; and discuss the importance of this information to develop larviculture protocols. When pacu larvae exhaust yolk reserves, they initiate a new form of interaction with the environment, becoming exclusively exotrophic. This type of interaction is made possible by the rapid development of sensory, skeletal, locomotor and digestive structures. In addition to understanding fish ontogeny, studies on larval development are necessary to improve farming systems and larviculture techniques aimed at producing high-quality juveniles in aquaculture.
