Jurnal Biologi, Volume 6 No 4, Oktober 2017 Hal. 71-81 PERILAKU BERTELUR DAN SIKLUS HIDUP Aedes aegypti PADA BERBAGAI MEDIA AIR Indira Agustin, Udi Tarwotjo, Rully Rahadian Laboratorium Ekologi dan Biosistematik Departemen Biologi FSM UNDIP agustinindira@yahoo.com, uditarwotjo@yahoo.com, rully.undip@gmail.com Abstrak Nyamuk Aedes Aegypti merupakan vektor utama pembawa penyakit demam berdarah. Penyebaran nyamuk Aedes aegypti di Indonesia sangat luas, nyamuk ini memiliki tempat perindukan pada air jernih seperti di bak mandi, pot bunga, tempat minum hewan peliharaan serta pada barang- barang bekas yang didalamnya tergenang air. Akan tetapi kondisi lingkungan yang terus berubah karena maraknya pencemaran membuat nyamuk Ae. aegypti terus beradaptasi terhadap lingkungan perindukannya. Penelitian ini bertujuan untuk mengetahui perilaku bertelur meliputi preferensi media yang dipilih oleh nyamuk, serta sikus hidup Aedes aegypti pada media air yang berbeda. Tahapan penelitian yang dilakukan meliputi : persiapan alat dan bahan penelitian, pengamatan preferensi nyamuk Ae. aegypti, dan pengamatan siklus hidup Ae. aegypti pada berbagai media air. Hasil penelitian menunjukan bahwa dari seluruh media air tercemar yang di ujikan nyamuk Ae.aegypti memiliki preferensi peletakan telur pada media air eceng gondok, diikuti oleh media air lindi, sedangkan pada media air limbah cair tahu dan limbah laundry tidak ditemukan adanya telur yang diletakan. Sedangkan pada penelitian lainnya diketahui bahwa daya tetas dan siklus hidup nyamuk Ae. aegypti pada media air tercemar seperti rendaman eceng gondok dan air lindi tidak berbeda nyata dari media air kontrol (tidak tercemar). Hasil penelitian tersebut diharapkan menjadi acuan bagi instansi terkait agar memperluas pemberantasan nyamuk Ae.aegypti ke tempat-tempat yang selama ini tidak biasa dilakukan pemberantasan Kata Kunci: Aedes aegypti, Rendaman eceng gondok, Lindi, Limbah Laudry, limbah Tahu Abstract Aedes aegypti is the main vector that transmits dengue fever. The spread of Aedes aegypti mosquitos in Indonesia is very wide. This mosquito has its breeding site in clear water areas such as in the bath water containers, flower pots, pet containers as well as in the used goods that can hold stagnant water. However, the environmental conditions which are constantly changing due to the rampant pollution cause Ae. Aegypti to continue to adapt to its breeding environment. This research aims to find out the egg laying behavior, life cycle and mediums preferences selected by Aedes aegypti mosquitos in different water mediums. Stages of the research which are conducted include: preparation of research tools and materials, observation on Ae. Aegypti mosquitos’ preferences, observation on egg hatchability and life cycle of Ae. Aegypti in various water mediums. The result shows that from all contaminated water mediums which are tested, Ae. Aegypti mosquitos have the preference of laying eggs in Eichhornia crassipes water mediums, followed by leachate water mediums, whereas in tofu wastewater mediums and laundry waste, there were no eggs found. Meanwhile, in another study, it is known that the egg hatchability and life cycle of Ae. Aegypti mosquitos in contaminated water mediums such Eichhornia crassipes immersed water mediums, and leachate water are not significantly different from controlled water mediums (uncontaminated). The result of the research is expected to be the reference for relevant institute in expanding the eradication of Ae. Aegypti mosquitos to places that have been unusual for eradication.
