Abstract Dengue Hemorrhagic Fever (DHF) is a disease caused by dengue virus and transmitted by Aedes aegypti mosquito as the main vector and Aedes albopictus as secondary vector. In 2016, Bengkulu City was one of 3 cities that experiencing DHF outbreaks in Indonesia. Insecticides malathion have been used since 1990 in bulk in DHF control programs in Bengkulu City and have not had an evaluation report on Aedes sp. vulnerability to malathion. The purpose of this research was to know the resistance status of Ae albopictus mosquitoes from endemic and sporadic areas of DHF in Bengkulu City to malathion. The sample of the study was the Ae. albopictus adult female mosquitoes which collected from endemic and sporadic areas of DHF in Bengkulu City with ovitrap installation. The resistance test was performed by CDC Bottle Bioassay method with malation 96% and 50 μg/ml diagnostic dose of. The results of this study showed 1% mortality on endemic area and 5% on sporadic area. Aedes albopictus of both areas were resistant to malathion.   Keywords: Ae. albopictus, bottle bioassay, malathion.   Abstrak Demam Berdarah Dengue (DBD) merupakan penyakit yang disebabkan oleh virus dengue dan ditularkan oleh nyamuk Aedes aegypti sebagai vektor utama dan Aedes albopictus sebagai vektor sekunder. Pada tahun 2016, Kota Bengkulu merupakan 1 dari 3 kota yang mengalami KLB DBD di Indonesia. Insektisida malation telah digunakan sejak tahun 1990 secara massal dalam program pengendalian DBD di Kota Bengkulu dan belum memiliki laporan evaluasi mengenai kerentanan Aedes sp terhadap malation.

Dengue Hemorrhagic Fever (DHF) is transmitted by Aedes aegypti and Ae. albopictus. Aedes aegypti chooses to live indoors and Ae. albopictus in outdoors. Aedes aegypti has been proven to play a role in dengue transmission in urban areas. It is assumed that suburbs dominated by gardens, so it is possible that Ae. albopictus acts as a vector. The study aimed to analyze the relationship between Ae. albopictus and DHF incidence in suburban area. The study was conducted in Godean, Sleman Regency. 280 ovitrap were placed indoors and outdoors at across seven villages. Each village was represented by one hamlet, so there were 40 ovitrap of each hamlet. The proportion of ovitrap containing Ae. aegypti and Ae. albopictus larvae was calculated. The results showed that Ae. aegypti larvae was more indoors (78.50%) than outdoors (21.45%) in all villages and negatively correlates with DHF (p=0.036; r=-0.776). Aedes albopictus larvae is more commonly found in gardens (80.64%) than in homes (19.36%) and does not correlate with DHF (p = 0.702). It was concluded that in suburban endemic area of ​​Sleman Regency, Ae. aegypti larvae was more indoors and negatively correlated with DHF. Aedes albopictus larva was more in the garden and did not correlate with DHF incidence.

Dengue hemorrhagic fever is a severe and fatal infection that occurs in tropical regions such as Indonesia. In 2014, recorded that dengue morbidity rate was 5.17 per 100,000 inhabitants (approximately 13031 cases) with mortality rate of 0.84% (110 deaths). Demographic and societal changes such as population growth, urbanization, and modern transportation appear to play an important role in the increased incidence and geographical spread of dengue virus. Aedes aegypti, the urban yellow fever mosquito, is also the principal dengue-carrying vector. The Aedes aegypti mosquitoes as a vector of dengue virus normally live and breed in clean water reservoirs that are not directly related to the land such as: bath, bird drinks, water pot, water jars / barrel, cans, old tires, etc. In Indonesia, dengue outbreaks often occur when the seasons change from dry to rain hor vice versa. This study aimed to figure out the influence of natural environment and the existence of the vector’s larva. A logistic regression was performed to ascertain the effects of temperature, humidity, water replacement and the existence of water reservoir on the likelihood of the existence of the vector’s larva . The logistic regression model was statistically significant, p < .005 and the model explained 69% (Nagelkerke R2). This finding shows that the existence of the mosquito’s larva, influenced by temperature, water replacement activity and the existence of water reservoir. Health education about vector control and environmental engineering are necessary to break the chain of mosquito breeding.

Background: The incidence rate (IR) of Dengue Hemorrhagic Fever per 100,000 population in Central Java has increased dramatically in five years. Banyumas Regency is an endemic area of ​​dengue hemorrhagic fever in Central Java Province. The cause of dengue hemorrhagic fever is four dengue viruses known as DEN-1, DEN-2, DEN-3, and DEN-4. The purpose of this research is to detect transovarial dengue virus in Aedes aegypti mosquito in Banyumas Regency. Methods: The study was conducted by installing ovitrap in Mersi Village, East Purwokerto District, and in Pliken Village, Kembaran District, Banyumas Regency. The study was conducted by installing ovitrap in Mersi Village (9 samples) and Pliken Village (3 samples). The eggs obtained are hatched into larvae in the laboratory. The 3rd and 4th instar larvae were examined for the presence of dengue virus using the Elisa method. Result: The results showed that in Mersi Village, there were two positive samples, and in Pliken Village, there was one positive sample containing dengue virus. The presence of the dengue virus found in the hatched Aedes aegypti larvae (F1) indicates that there has been a transovarial dengue virus from the parent mosquito in its offspring. Conclusion: The study concluded that in Banyumas District, a dengue virus transovarial had occurred in Aedes aegypti mosquitoes. The government and the community should increase efforts to eradicate mosquito nests (dengue hemorrhagic fever) to reduce the vector population of dengue hemorrhagic fever so that cases of dengue hemorrhagic fever can be eliminated.    Keyword: Transovarial dengue virus, Aedes aegypti, Dengue Hemorrhagic Fever

Abstract. Dengue hemorrhagic fever (DHF) is a very serious health problem, especially in Indonesia. Dengue hemorrhagic fever is caused by the Dengue Virus transmitted by Aedes aegypti mosquito vector as the actual vector and Aedes albopictus as the potential vector. Various efforts have been implemented but the incidence of dengue is still high. One of the spearheads in eradicating DHF is to break the chain of transmission through the Mosquito Nest Eradication program. To support the PSN program, Jumantik Monitors are formed in each village. However, due to limited resources, monitoring by jumantik has not been entirely successful. Based on this, it is necessary to consider the effectiveness of the implementation of this jumantik through the SARUJU program, namely the one jumantik per house program. Jumantik was a medical student at the University of Riau who became a foster child in village namely Pelita Medika Buluh Cina Village. Jumantik has the duty to monitor the existence and density of larvae, implement PSN and appoint a second jumantik who is a member of the original family. Through the first stage larvae survey, there was a high rate of larvae density. Through Saruju activities, it is expected that a decrease in larvae density will reduce the incidence of DHF. Keywords: Dengue hemorrhagic fever, Saruju, JumantikAbstrak. Demam berdarah dengue (DBD) merupakan masalah kesehatan yang sangat serius, terutama di Indonesia. Demam berdarah dengue disebabkan oleh Virus Dengue dengan perantaraan vektor nyamuk Aedes aegypti sebagai vektor aktual dan Aedes albopictus sebagai vektor potensial. Berbagai upaya telah dilakukan pemerintah melalui program yang telah dilaksanakan, namum kejadian DBD masih tetap tinggi. Salah satu ujung tombak pemberantasan DBD adalah dengan memutus rantai penularan melalui program Pemberantasan Sarang Nyamuk (PSN). Namun demikian program tersebut tidak dilaksanakan secara efektif pada berbagai lapisan masyarakat. Untuk menunjang program PSN dibentuklah Juru Pemantau Jentik (Jumantik) pada tiap kelurahan. Namun demikian karena keterbatasan sumber daya menyebabkan pemantauan oleh jumantik tidak berhasil Berdasarkan hal tersebut perlu dipikirkan efektifitas pelaksanaan jumantik ini melalui gerakan SARUJU yaitu gerakan satu rumah satu jumantik. Jumantik berasal dari mahasiswa Fakultas Kedokteran UNRI yang merupakan anak asuh dari Desa Binaan Kampung Pelita Medika II Buluh Cina. Jumantik berkewajiban memantau keberadaan dan kepadatan jentik di rumahnya, melaksanakan PSN, serta menunjuk dan mengedukasi jumantik kedua yang merupakan anggota keluarga asli. Berdasarkan survey jentik didapatkan kepadatan jentik yang tinggi di daerah tersebut. Melalui kegiatan saruju diharapkan kejadian DBD di daerah tersebut dapat ditekan.Kata kunci: Demam berdarah dengue, Saruju, Jumantik
