Entomological surveys (2001-2005) were carried out in Narathiwat Province to determine mosquito fauna of the peat swamp forest. Fifty-four species belonging to 13 genera were identified from 837 larval specimens and 3,982 adult mosquitoes. These included the major vectors for Brugian fillariasis: Mansonia annulata, Ma. bonneae, Ma. dives, Ma. uniformis and Ma. indiana. Ma. annulata and An. letifer were reported for the first time in Thailand as lymphatic filariasis vectors. Three species inhabiting Nepen- thes pitchers (N. mirabilis): Tripteroides tenax, Toxorhynchites manopi and Uranotaenia edwardsi, were recorded for the first time in Thailand; Zeugnomyia gracilis was also found common in the peat swamp forest.

For instance, malaria, dengue hemorrhagic fever and filariasis remain endemic in Pangkajene Regency and Islands Regencies.The existence of these vectors will affect the transmission of potential vector-borne diseases. The purpose of this research is to determine the potential transmission of those diseases including Japanese encephalitis in those areas. Data were collected by catching adult mosquitoes and larvae in forest, non-forest and coastal ecosystems according to the WHO methods, including human man landing collection, animal baited trap net, animal feed, resting morning, and light trap. The larva survey was conducted at the mosquito breeding place. Pathogens in mosquitoes were detected in a laboratory using Polimerase Chain Reaction. The study found plasmodium in some species. They were Anopheles vagus in a residential ecosystem near settlement, Anopheles subpictus in forest ecosystems near settlements and non forest remote settlements, Anopheles barbirostris was found near and remote forest ecosystems, Anopheles indifinitus found in nearby forest ecosystems and non- forest close to settlements.

The impact of climate variability on vector-borne diseases is well documented. The increasing morbidity, mortality and health costs of dengue and dengue haemorrhagic fever (DHF) are escalating at an alarming rate. Numerous efforts have been taken by the ministry of health and local authorities to prevent and control dengue. However dengue is still one of the main public health threats in Malaysia. This study was carried out from October 2009 by a research group on climate change and vector-borne diseases. The objective of this research project is to assess the community vulnerability to climate variability effect on dengue, and to promote COMBI as the community responses in controlling dengue. This project also aims to identify the community adaptive measures for the control of dengue.

  • A Revision of the Mosquitos of the Palaearctic Region

    A Revision of the Mosquitos of the Palaearctic Region

    263 A REVISION OF THE MOSQUITOS OF THE PALAEARCTIC REGION. By F. W. EDWARDS. (Published by permission of the Trustees of the British Museum.) For some years after the intensive study of mosquitos began in tropical countries, surprisingly little interest was taken in the European species, particularly those of Northern Europe. Ficalbi had published his monographic revision in 1896-99, but from then until 1914 very little further had been done ; the adults were assumed to be more or less known, though very few of the larvae had been described. Since 1914, however, a great deal of work has been done all over Europe, bionomic as well as systematic, and considerable advances have been made in every branch of our knowledge of these insects. The present paper was commenced early in 1919, with the study of a number of large collections received at the British Museum from Italy (Mr. E. Hargreaves), Macedonia (Capt. J. Waterston), Palestine and Mesopotamia (Capt. P. J. Barraud), and Egypt (Major E. E. Austen). Shortly afterwards a correspondence with Dr. Wesenberg-Luhd, of Copenhagen, made it evident that there were many more species in Northern Europe than had previously been supposed. I therefore determined to attempt a revision of the Palaearctic mosquito fauna, and with this end in view wrote to the Dipterists in charge at various continental museums, as well as some private collectors, for the loan of material for determination or re- determination. Collections were sent in response to my requests by Dr. R. Frey, Helsingfors Museum ; Dr. E. Bergroth, Jamsa, Finland ; Dr. Y.

Oliveira1, Lee W. Cohnstaedt2, Erin Strathe3, Luciana Etcheverry Hernández1, D. Scott McVey2, José Piaggio4 and Natalia Cernicchiaro1* Abstract Background: Japanese encephalitis (JE) is a zoonosis in Southeast Asia vectored by mosquitoes infected with the Japanese encephalitis virus (JEV). Japanese encephalitis is considered an emerging exotic infectious disease with potential for introduction in currently JEV-free countries. Pigs and ardeid birds are reservoir hosts and play a major role on the transmission dynamics of the disease. The objective of the study was to quantitatively summarize the proportion of JEV infection in vectors and vertebrate hosts from data pertaining to observational studies obtained in a systematic review of the literature on vector and host competence for JEV, using meta-analyses. Methods: Data gathered in this study pertained to three outcomes: proportion of JEV infection in vectors, proportion of JEV infection in vertebrate hosts, and minimum infection rate (MIR) in vectors. Random-effects subgroup meta-analysis models were fitted by species (mosquito or vertebrate host species) to estimate pooled summary measures, as well as to compute the variance between studies. Meta-regression models were fitted to assess the association between different predictors and the outcomes of interest and to identify sources of heterogeneity among studies. Predictors included in all models were mosquito/vertebrate host species, diagnostic methods, mosquito capture methods, season, country/region, age category, and number of mosquitos per pool.

The present study was conducted in the years 2000-2002 to determine the bionomics of Mansonia mosquitoes, vectors of nocturnally subperiodic Brugia malayi, inhabiting the peat swamp forest, “Phru Toh Daeng”, Narathiwat Province, Thailand. Fifty-four species of mosquitoes belonging to 12 genera were added, for the first time, to the list of animal fauna in the peat swamp forest. Mansonia mosquitoes were the most abundant (60-70%) by all collection methods and occurred throughout the year with a high biting density (10.5-57.8 bites per person-hour). Ma. bonneae was most prevalent (47.5%) and fed on a variety of animal hosts, including domestic cats, cows, mon- keys, and man with a maximum biting density of 24.3 bites per person-hour in October. The infec- tive bites were found for the first time in Ma. annulata collected at Ban Toh Daeng (13 00-14 00 hours) and also Ma. bonneae at forest shade (16 00-17 00 hours) and in a village (20 00-21 00 hours) with rates of 0.6, 1.1 and 1.0%, respectively.The biting activities of these two species oc- curred in both the day and night time, with two lower peaks at 10 00 hours (18.5 bites per person- hour) and 13 00-15 00 (8.5-10.0 bites per person-hour) hours, but the highest peak was 19 00-21 00 hours (31.5-33.0 bites per person-hour) The biting activity patterns corresponded with the peri- odicity found in man and domestic cats and may play an important role in either transmission or maintenance of the filarial parasites in the peat swamp forest.
