“…Space spraying has little effect on the mosquito population, and thus on dengue transmission [4]. In Asia and America, studies have shown that after application of the ultra-low volume spray, the density of the adult population of Aedes mosquitoes returned to the pre-treatment level within 2 weeks and even with multiple applications, the impact of the spray was minimal [5]. The most annoying report on fogging has come in from the city of Bandung, Indonesia.…”

In 2017, the impact of fogging on transmission of dengue was studied in Kolkata City, India. As revealed, the measure failed to yield any positive results. Despite the massive fogging being carried out in different municipal wards, no sign of reduction in the number of dengue cases was visible. At the behest of Atin Ghosh, deputy mayor [erstwhile mayoral council member [health] of Kolkata Municipal Corporation, the fogging was banned in 2019 and an era of vector management by applying all possible means of source reduction brought in.

“…DHF cases in Malang Regency in 2017 were 451 cases, an increase of 682 cases in 2018 (BPS, 2018). Efforts made by the government through the health department are the fogging program (Yee et al, 2017), larvae eradication using abate (Suriami et al, 2020), cypermethrin (A. P. de Araujo et al, 2019) as a vector control program.…”

DHF cases tend to increase from year to year in Indonesia. So the government makes efforts to control cases of Dengue Fever (DHF) which are usually done chemically and harm the environment and health. There is a need for safer, more effective, and environmentally friendly controls, such as using natural ingredients as natural larvicides. Among the natural ingredients having potential as a larvicide is Bintaro leaves (Cerbera manghas). The purpose of this study was to determine the toxicity of Bintaro leaf extract against third instar larvae of Aedes aegypti mosquitoes. This experimental study used 7 treatments of Bintaro leaf extract concentration (5 %, 15 %, 25 %, 35 %, 45 %, 65 %, 75 %), abate as a positive control, and distilled water as a negative control. Each treatment used ten instar III Aedes aegypti larvae with four repetitions. The data obtained were then analyzed using probit analysis to determine the toxicity of Bintaro leaf extract to Aedes aegypti larvae by calculating the LC50 and LC90 values. The results showed that the most effective concentration was 75 % because it could kill 100% of the test larvae. The LC50 value of 5,097 % and the LC90 value of 25,300 % indicate that the level of toxicity is very toxic. The probit regression analysis shows a linearity line equation y = 1.15 + 1.43x with a correlation (R2) of 0.512 which indicates that the correlation is strong enough. It is related to the content of flavonoids, tannins, saponins, triterpenoids which are toxic to the abdomen, nervous system, and respiratory system of larvae. From the research results, Bintaro extract with a concentration of 75 % can be used as a natural larvicide candidate. Furthermore, further research to see the toxicity to the environment can be done.are toxic to the abdomen, nervous system, and respiratory system of larvae.

“…It is done in the area around the patient's house until the radius of 100 -200 meters. Some studies have demonstrated the effectiveness of fogging in increasing the percentage of free larvae and reducing the percentage of larvae [12,30] However, fogging with malathion only kills adult mosquitoes, and it does not kill the existing larva, so the larva in the target area can still develop into adult mosquito. However, not all larvae that develop into adult mosquitoes carry dengue virus.…”

The incidence rate (IR) of dengue hemorrhagic fever (DHF) in Indonesia has increased in recent years and still causes a health problem. Makassar, as one of the big cities in Indonesia, is also experiencing of DHF cases. According to the Health Office of Makassar City, DHF cases during 2014-2016 has increased from 139 to 250 cases. The defense mechanism of dengue virus in transovarial transmission from female mosquitoes to eggs is estimated to be one of the factors that increase the rate of DHF. In addition, the circulation of the Aedes aegypti mosquitoes can also affect the increase of the rate. This study aims are to identify ovitrap index and to find out how much the vertical transmission of dengue virus by measuring the minimum infection rate (MIR) and the distribution of four dengue virus serotype in Ae. aegypti mosquitoes in the city of Makassar, South Sulawesi, as well as their association with the incidence rate (IR) in the area. This observational research uses ecological study with cross-sectional approach. The samples of the study are male and female mosquitoes from Ae.aegypti eggs obtained from the installation of ovitrap in 30 urban villages in Makassar. Dengue virus identification was performed using a reverse transcriptase polymerase chain reaction (RT-PCR). These results showed that the ovitrap index (IO) was in the range of 0-66.7%. The average value of the ovitrap index outside the house (44.44%) was greater than inside house (37.22%). The results of identification of dengue virus using RT-PCR showed negative results as indicated by the non-formation of a band on 75 pools male and 78 pools female Ae. aegypti mosquitoes after electrophoresis. The results of this study indicated that the Ae. aegypti mosquito in Makassar City showed a tendency to lay eggs outside the house due to the habit of the people who put rain water shelters outside the house which could become breeding place for Ae. aegypti mosquitoes. This study also showed that there was no transovarial transmission of DENV found in male and female Ae. aegypti mosquitoes in Makassar City during November 2017 until January 2018.
