| dc.description.abstract | A study was conducted in the rural village of Kampung Bongor, Grik in the north eastern part of Hulu Perak, Malaysia to examine the bionomics of the population of Anopheles sp. in that locality. The mosquito collection was done using CBT (cow baited trap) method. A total of 4,497 Anopheles mosquitoes were caught during the 14 months col~ection period from January 2005 to February 2006 and 11 species were identifie'd. They were An. barbirostris, An. umbrosus, An. nigerrimus and An. separatus from the Anopheles (Cellia) subgenus group, and An. aconitus, An. maculatus, An. philippinensis, An. vagus, An. kochi, An. tessel/atus and An. subpictus from the Anopheles (Anopheles) subgenus group. The seasonal distribution of most of the population of Anopheles sp. mosquitoes is, partly influenced by the rainfall pattern. The distribution is generally higher during heavy rainfall and lower during the drier months. However, environmental and geographical changes also affect the distribution pattern. Generally the biting rhythm begins after sunset and its activities decrease before sunrise with the peak of activity occurring around midnight. A survey was also carried out in Kampung Tepin, Balai Ringin, in the Serian district in Sarawak to look at the population of Anopheles mosquitoes available during the month of February 2006. The HBT (human baited trap) method by human landingbiting catches was used for the collection of mosquitoes in this locality. During the whole collection period, a total of 2,654 An. letifer were caught. Generally, the biting activity of An. letifer in Kampung Tepin begins an hour after sunset and its activities increases rapidly in two hours time. An insecticide susceptibility test using the WHO test kits and impregnated papers with 0.75 % permethrin was carried out on two strains of Anopheles from two different locations in Malaysia to determine their insecticide resistance status. Results show that An. maculatus from Kampung Bongor, Grik recorded KTso and KT9S value of 28.09 minutes and 62.98 minutes respectively. Anopheles letifer from Kampung Tepin, Balai Ringin recorded KTso and KT9S value of35.09 minutes and 73.03 minutes respectively. Both An. maculatus and An. letifer showed 100 % mortality after 24 hour holding period. | en_US |
