“…An. minimus has been reported to have changed to a greater preference for host seeking outdoors in Thailand (Ismail et al 1978, Harrison 1980, Ratanatham et al 1988, Chareonviriyaphap et al 2003, Sungvornyothin et al 2006) and in China (Wu and Chen 1993). The variations observed in landing places of this species in different areas were thought to be caused by the different strains or sibling species.…”

The host feeding of Anopheles minimus Theobald and An. fluviatilis James was studied in the villages of east-central India by conducting human landing collections between 1800 and 0600 hours at monthly intervals from May 2006 to July 2007. Four species of anopheline mosquitoes, An. minimus, An. fluviatilis, An. maculatus Theobald, and An. subpictus Grassi, were collected, the former two known vector species of malaria being the most abundant (97.1%). The An. minimus complex has been identified as sibling species A and An. fluviatilis complex as species S (90.9%) and T (9.1%). Both the species were prevalent throughout the year and obtained from landing collections indoors and outdoors. The average human landing density (HLD) of An. minimus and An. fluviatilis was 1.76 and 1.78 indoors and 1.71 and 1.56 per human per night outdoors, respectively. The HLD was relatively higher during the rainy season, although not significant in the case of An. fluviatilis. The human landing activity of An. minimus and An. fluviatilis occurred between 2000 and 0400 hours and peaked during 2300-0200 hours both indoors and outdoors.

“…Cross-resistance as a consequence of unintentional or extensive use of the same or related groups of compounds in mosquito populations has been reported elsewhere. 12,18,21) A high level of physiological resistance to DDT in Cx. quinquefasiatus could be related to the previous use of DDT in agriculture and public health.…”

Several countries continue to experience endemic and reemerging dengue fever (DF) and dengue hemorrhagic fever (DHF). 1) Annually, millions of people are estimated to be infected with dengue virus worldwide. 2,3) In Thailand, outbreaks of DHF were first recognized in 1958 and subsequently the disease has expanded throughout the country. 4) Approximately 40,000 cases of dengue with a mortality rate of 0.09 (per 100,000 people) were reported in 2007. 5) In spite of continued vigilance in control methods, dengue cases remain a major health threat in Thailand. The reason is unclear but is possibly related to the increase of human and economic activities in urban and semi-urban zones. Moreover, traditional water storage practices increase the breeding sites for Aedes aegypti, a primary vector of DF and DHF in Thailand. 6,7) Aedes aegypti, a daytime biting mosquito, is highly anthropophilic, often resides in and near human dwellings and preferentially feeds on humans. 1,8,9) This species has been found to be highly adapted to all man-made and natural environments and is a potential vector of dengue. [10][11][12] The key to preventing dengue transmission is to reduce human-vector contact using synthetic chemicals. [13][14][15][16][17] Several synthetic insecticides, including organochlorines, organophosphates, carbamates and synthetic pyrethroids, have been used in dengue control programs. 18) DDT (organochlorine) was widely used to control Ae. aegypti after the first dengue epidemic in 1958. 19,20) Deltamethrin (synthetic pyrethroids) is currently one of the most commonly used insecticides in public health programs and has been the mainstay for the emergency control of Ae. aegypti adults in Thailand since 1994. 18,21) Temephos (organophosphate) is commonly used in water containers for the control of Ae. aegypti larvae. Ultra-low-volume (ULV) applications of fenitrothion and malathion are used during the peak period of adult Aedes populations, especially during the rainy season. 16 (Received April 24, 2008; Accepted June 26, 2008) In this study, nine strains of Aedes aegypti mosquitoes from different localities in Thailand were subjected to susceptibility tests against commonly used insecticides for vector control in Thailand. Aedes aegypti from different localities were strongly resistant to DDT and permethrin, except for one strain from Chiang Mai (Chiang Mai-P) that was found to be susceptible to permethrin. In contrast, most Ae. aegypti strains are susceptible to deltamethrin and alphacypermethrin, except that Bangkok and Nonthaburi strains showed incipient resistance to deltamethrin and alphacypermethrin, respectively. Various levels of malathion and propoxur susceptibility were also detected in Ae. aegypti strains; however, two strains of Ae. aegypti (Satun and Nonthaburi) were found to be completely susceptible to malathion. The insecticide susceptibility level in three strains of Culex quinquefasciatus was also investigated. The results indicated strong resistance to DDT and moderate resistance to permethri...
