Susceptibility Of Field-Collected Aedes Aegypti (L.) (Diptera: Culicidae) To Bacillus Thuringiensis Israelensis And Temephos, Mohd Sofian Bin Azirun
Susceptibility Of Field-Collected Aedes Aegypti (L.) (Diptera: Culicidae) To Bacillus Thuringiensis Israelensis And Temephos, Mohd Sofian Bin Azirun
Mohd Sofian Bin Azirun
The susceptibility status of field-collected Aedes aegypti (L.) from a dengue endemic area to Bacillus thuringiensis israelensis (Bti) and temephos was determined. Since August 2007, biweekly ovitrap surveillance (OS) was conducted for 12 mo in 2 sites, A & B, in Shah Alam, Selangor. Site A was treated with a Bti formulation, VectoBac® WG at 500 g/ha, from December 2007 - June 2008 while Site B was subjected to routine dengue vector control activities conducted by the local municipality. Aedes aegypti larvae collected from OS in both sites were bred until F3 and evaluated for their susceptibility. The larvae were …
Laboratory Bioefficacy Of Nine Commercial Formulations Of Temephos Against Larvae Of Aedes Aegypti (L.), Aedes Albopictus Skuse And Culex Quinquefasciatus Say, Mohd Sofian Bin Azirun
Laboratory Bioefficacy Of Nine Commercial Formulations Of Temephos Against Larvae Of Aedes Aegypti (L.), Aedes Albopictus Skuse And Culex Quinquefasciatus Say, Mohd Sofian Bin Azirun

The bioefficacy of nine commercial formulations of temephos against Aedes aegypti, Aedes albopictus and Culex quinquefasciatus larvae were evaluated in the laboratory. WHO larval bioassay with operational dosage of temephos at 1 mg/L was performed. The larval mortality was recorded every 5 minutes until complete mortality was achieved. All formulations of temephos exhibited various toxicity level against Ae. aegypti, Ae. albopictus and Cx. quinquefasciatus. Generally, larvae of Cx. quinquefasciatus was susceptible to all formulations of temephos, followed by Ae. aegypti and Ae. albopictus.

First Report Of The Signal Fly, Scholastes Sp (Diptera: Platystomatidae) Visiting Animal Carcasses In Malaysia, Chen Chee Dhang
Chen Chee Dhang
Signal fly, Scholastes sp. (Diptera: Platystomatidae) was observed associated with animal carcasses in Malaysia. The first observation was on a monkey carcass, which was killed by using a handgun and immediately placed in a forested area in Gombak, Selangor while the second observation was on a pig that died of natural causes and whose carcass was placed in an oil palm plantation in Tanjung Sepat, Selangor. Both animal carcasses were visited by Scholastes sp. flies during the fresh decomposition period. However, the role Scholastes flies in the decomposition process remains unknown. In this paper, we report the occurrence of Scholastes …
