Abstract

Abstract. Culex quinquefasciatus mosquito is increasing problem of public health, being the vector responsible for West Nile Virus and Filariasis. Clorpirifos (Organofosfat) and Metonil (Carbamat) were known to posses insecticide activity against insect. The study was aimed to examine effectiveness of Klorpirifos and Metonil as larvicide against C. quinque-fasciatus larval. Klorpirifos a significantly higher larvicidal activity against 3th-4th instar larvae of C. quinquefasciatus than Metonil. The larval mortality was observed after 24 h ex-posure. The LC95 value of Klorpirifos and Metonil were 3,139 mg/lt and 9,045 mg/lt, against C. quinquefasciatus. The mixed of both insecticide was LC95 value 2,823 mg/lt. The result of this study suggested that Klorpirifos more effective larvicide against C. quinquefasciatus than Metonil.

Abstract

The incidence rate of Dengue Hemorrhagic Fever (DHF) disease in Indonesia is increasing over years. DHF outbreaks happen in many provinces of Indonesia. West Java is a DHF endemic province. Nearly all districts/municipalities at the West Java Province are endemic areas and have reported DHF outbreaks. Factors supporting high incidence rate of DHF are tropical climate of Indonesia and the circulation of four dengue virus serotypes. The study aimed to identify dengue virus serotype distribution in the districts with different DHF endemic at the Province of Jawa Barat. The study was observational with cross sectional design. Samples consisted of 60 samples of blood serum of patients serologically infected by dengue virus. Samples came from three districts/municipalities with different DHF endemic. Dengue virus serotype of samples was detected using nested RT-PCR (Reserve Transcription Polymerase Chain Reaction) examination.Results showed that, four serotypes of dengue virus could be isolated from serum samples. Out of all positive samples, Den-2 was the serotype most frequently appeared (55%) followed by Den-3 (29%), Den-1 (9.6%) and Den-4 (6.4%). At dengue high endemic areas there were 4 serotypes of dengue virus Den-3 (6 times), Den-2(twice), Den-4 and Den-1 (once each). At medium endemic areas there were 4 serotypes of dengue virus, i.e. Den-2 (9 times), Den-3 (twice), Den-1 and Den-4 (once each). At low endemic areas there were two serotypes, i.e. Den-2 (6 times) and Den-1 (once).
