Karyotypes and crossing relationships were investigated for three allopatric populations of Anopheles leucosphyrus in Southeast Asis: South Kalimantan, Sumatra an Thailand. The mitotic karyotypes of these populations were similar to those previously observed in other species of the An. leucosphyrus group. Populations from Thailand and South Kalimantan exhibited telocentric and subtelocentric sex chromosomes, respectively, with a distinctive band of intercalary heterochromatin in the X chromosome. Strikingly different submetacentric X and Y chromosomes were observed in the population from Sumatra, and it seems likely that the evolution of these chromosomes were observed in the population from Sumatra, and it seems likely that the evolution of these chromosomes occurred through the acquisition of constitutive heterochromatin. Sterile F1 males were observed in crosses between the Sumatra population and the populations from South Kalimantan and Thailand. No genetic incompatibility was observed in crosses between the latter two populations. We believe that the present concept of An. leucosphyrus includes two allopatric species, one inhabiting Borneo, West Malaysia and southern Thailand and one confined to Sumatra. Reprints.

Download Anopheline Species Complexes in South and South-East Asia Book in PDF, ePub and Kindle
Vector-borne diseases are a major health problem in South-East Asia and in other parts of the world. There are about 4,500 mosquito species in existence; species belonging to the Anopheles genus transmit malaria. Combating malaria is part of the Millennium Development Goals, and vector control is a key strategy both regionally and globally. Therefore, the review and dissemination of information on vector species is critically important. Most of the anophelines that are involved in the transmission of malaria in South and South-East Asia have been identified as species complexes. Members of a species complex are reproductively isolated evolutionary units with distinct gene pools and hence they differ in their biological characteristics. In 1998 WHO published Anopheline Species Complexes in South-East Asia. New identification tools have been developed since then, and therefore this updated edition was needed. It summarizes work that has been done on anopheline cryptic species and will be highly valuable to researchers, field entomologists and malaria-control program managers.

Download Advances in Parasitology Book in PDF, ePub and Kindle
First published in 1963, Advances in Parasitology contains comprehensive and up-to-date reviews in all areas of interest in contemporary parasitology. Advances in Parasitology includes medical studies on parasites of major influence, such as Plasmodium falciparum and trypanosomes. The series also contains reviews of more traditional areas, such as zoology, taxonomy, and life history, which shape current thinking and applications. Eclectic volumes are supplemented by thematic volumes on various topics, including control of human parasitic diseases and global mapping of infectious diseases. The 2011 impact factor is 4.39.

Download Biodiversity of Malaria in the World Book in PDF, ePub and Kindle
One million dead a Wear, 500 million with the disease, 2.5 billion people at risk : this is the malaria balance sheet in 2007. The distribution and seriousness of the disease depend on the pathogens and vectors involved, as welt as environmental conditions. Of the four parasites (Plasmodium), only P. falciparum kilts although the other three cause debilitating disease with regular relapses and recrudescence. More than fifty species of Anopheles can fulfil the vector rote which is essential in transmission of the parasite between human beings. Climatic factors (temperature and rainfall), the environment and biogeographical particularities dictate the distribution of anopheline species and determine transmission rates. This is why it makes sense to tank about the biodiversity of malaria. Today, more than 90% of deaths from malaria occur in Tropical Africa which is home to only 10% of humanity. Every 30 seconds a child dies from malaria. This continent harbours the most effective vectors (An. gambiae and An. funestus, in particular) and the climate is highly conducive to transmission of the disease. Severe malaria is also seen in forest foci in Southeast Asia, Papua-New Guinea and the Amazon. In the rest of the tropical and subtropical world, P. vivax and/or P malariae cause less severe disease.
