The Difference

Dengue hemorrhagic fever (DHF) is a vector-borne disease that still happens every year in Indonesia. This disease is caused by the dengue virus and transmitted by the Aedes aegypti as its vector. One of the biological vector controls that can be implemented is using fish as a predator of mosquito larvae, such as using Electric Yellow Cichlid fish (Labidochromis caeruleus) and Tinfoil Barb fish (Barbonymus schwanenfeldii). This study aimed to determine the difference in predation capacities of Electric Yellow Cichlid and Tinfoil Barb on Ae. aegypti larvae. This research is quasiexperimental with a completely randomized design (CRD) with Post Test Only research design. One aquarium with three liters of water containing one fish is given 25 Ae. aegypti larvae. Testing of each fish species is carried out in five replications. Fish predation was observed every 30 seconds until all larvae were eaten. The result showed that Electric Yellow Cichlid could prey on 25 larvae in an averagetime of 5.7 minutes, while Tinfoil Barb spent 11.6 minutes. The results of the Friedman test showed that there was a significant time difference in preying time of Electric Yellow Cichlid and Tinfoil Barb. It’s concluded that Electric Yellow Cichlid was more effective as an Ae. aegypti larvae predator.

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.
