Global Health Problem

ABSTRACT Dengue hemorrhagic fever is a global health problem and can be transmitted through vectors, namely Aedes aegypti. One of the controls can be through lethal ovitrap combined with attractant. This study aims to compare the percentage of trapped eggs, the number of eggs hatched, and larval mortality in the lethal ovitrap that were given two additional types of attractants. The insecticides used were temephos, while the attractants used were 20% straw soaking water, and water that Ae. aegypti have used to lay eggs. The type of research is an experiment with a completely randomized design. The sample used was female mosquito of Ae. aegypti that is full of blood from laboratory colonization. The results showed that straw soaking water was more influential attractant than the former Ae. aegypti colonization water in attracting Ae. aegypti mosquitoes to lay eggs. The highest larval mortality was found in a combination of lethal ovitrap with straw soaking water. Statistically there is an influence of the type of attractant on hatchability and the development of Ae. aegypti into adult mosquitoes. The combination of lethal ovitrap and attractant of straw soaking water can be an alternative control strategy for DHF program managers to reduce the density of Ae. aegypti mosquitoes and minimize transmission of dengue hemorrhagic fever in an area. Keywords: Aedes aegypti, attractant, lethal ovitrap, straw soaking water   ABSTRAK Demam berdarah dengue merupakan masalah kesehatan global dan dapat ditularkan melalui vektor yaitu Aedes aegypti. Salah satu pengendaliannya dapat melalui lethal ovitrap yang dipadukan dengan atraktan. Penelitian ini bertujuan untuk membandingkan persentase jumlah telur terperangkap, jumlah telur menetas, dan mortalitas larva pada lethal ovitrap yang diberi tambahan dua jenis atraktan. Insektisida yang digunakan adalah temefos, sedangkan atraktan yang digunakan adalah air rendaman jerami dengan konsentrasi 20%, dan air bekas kolonisasi/telur larva Ae. aegypti. Jenis penelitian ini adalah eksperimen dengan rancangan acak lengkap. Sampel yang digunakan adalah nyamuk Ae. aegypti betina yang kenyang darah hasil kolonisasi di laboratorium. Hasil penelitian menunjukkan bahwa air rendaman jerami merupakan atraktan yang lebih berpengaruh dibandingkan air bekas kolonisasi Ae. aegypti dalam menarik nyamuk Ae. aegypti untuk bertelur. Mortalitas larva tertinggi terdapat pada kombinasi lethal ovitrap dengan air rendaman jerami. Secara statistik ada pengaruh jenis atraktan terhadap daya tetas dan perkembangan Ae. aegypti menjadi nyamuk dewasa. Kombinasi lethal ovitrap dengan atraktan air rendaman jerami dapat menjadi strategi pengendalian alternatif bagi pengelola program DBD untuk mengurangi kepadatan nyamuk Ae. aegypti dan meminimalisasi transmisi penyakit demam berdarah dengue di suatu wilayah.

The Relationship

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.

AbstrakPengendalian vektor penyakit demam berdarah (DBD) di Indonesia menggunakan larvasida temephos telah berlangsung lebih dari 30 tahun, oleh karena itu, perlu dilakukan penelitian untuk mengetahui efektivitas temephos dan Bacillus thuringiensis var. israelensis yang merupakan larvasida jenis baru dari agen biologi terhadap larva nyamuk Aedes aegypti. Penelitian ini bertujuan untuk mengetahui perbandingan efektivitas temephos dengan B. thuringiensis var. israelensis terhadap mortalitas larva nyamuk Ae. aegypti dari tiga Kecamatan di Samarinda, yaitu Kecamatan Samarinda Utara Kelurahan Gunung Lingai, Samarinda Ulu Kelurahan Air Putih dan Sungai Kunjang Kelurahan Loa Bakung. Metode yang digunakan adalah metode bioassay. Hasil penelitian menunjukan bahwa temephos tidak efektif untuk membunuh larva nyamuk Ae. aegypti dari tiga kelurahan yang diamati, dengan LC50,24jam sebesar 1,88–2,24 ppm dan LC90,24jam sebesar 2,07–3,59 ppm. Sementara itu, B. thuringiensis var. israelensis masih efektif untuk membunuh larva nyamuk Ae. aegypti dari ketiga kelurahan yang diamati, dengan LC50,24jam sebesar 0,93–1,00 mL/50 L air dan LC90,24jam sebesar 1,05–1,11 mL/50 L air. Hal ini berarti penggunaan B. thuringiensis var. israelensis dengan dosis yang dianjurkan pemerintah masih efektif untuk mengendalikan populasi nyamuk Ae. aegypti.AbstractThe control of dengue hemorrhagic fever (DHF) vector in Indonesia using larvicide temephos has been ongoing for more than 30 years. Hence, it is necessary to assess the effectiveness of temephos compared to Bacillus thuringiensis var. israelensis which is a new type of biological larvacide agent against Aedes aegypti mosquito larvae. This study aimed to determine the effectiveness of temephos compared to B. thuringiensis var. israelensis against mortality of Ae. aegypti mosquito larvae sampled from three subdistricts in Samarinda namely Samarinda Utara Subdistrict Gunung Lingai, Samarinda Ulu Subdistrict Air Putih, and Sungai Kunjang Subdistrict Loa Bakung. The method used was bioassay. The results showed that temephos was not effective in killing Ae. aegypti mosquito larvae from the three subdistricts observed, with LC50.24 hours by 1.88–2.24 ppm, and LC90,24 hours by 2.07–3.59 ppm. Meanwhile, B. thuringiensis var. israelensis is still effective in killing Ae. aegypti mosquito larvae from the three subdistricts observed, with LC50.24 hours by 0.93–1.00 mL/50 L of water and LC90,24 hours by 1.05–1.11 mL/50 L of water. Those results mean that the application of B. thuringiensis var. israelensis with the recommended dosage of the government is still effective in controlling the population of Ae. aegypti.
