Abstract Considerable previous research has focused on predator-associated semiochemicals and how they affect mosquito oviposition behavior. However, most of this work has been done without taking into consideration either the natural density of the predators or how other semiochemicals in aquatic environments might affect the responses of gravid mosquitoes. The influence of mosquitofish density, source water (tap vs pond), presence of freshly laid egg rafts, and removal of a putative source of semiochemicals (bacteria) on oviposition by Culex tarsalis Coquillett (Diptera: Culicidae) was studied in laboratory bioassays. Culex tarsalis females were deterred from laying egg rafts on water that contained semiochemicals associated with Gambusia affinis (Baird & Girard), but this deterrence was not strongly associated with the density of fish used to condition aged tap water. The number of egg rafts laid onto Gambusia-exudate water made with either tap water (density < 1 fish per liter) or pond water was typically ≥ 50% of that onto water that did not house mosquitofish. Gravid mosquitoes tested individually did not reduce oviposition onto Gambusia-exudate water as compared to controls. Likewise, oviposition by females with ablated wings did not differ significantly between Gambusia-exudate water and controls. Oviposition onto filter-sterilized Gambusia-exudate water was reduced relative to unfiltered water, suggesting that semiochemicals deterring egg-laying were still present after bacteria were removed. Taken together, these findings suggest that the responses of gravid Cx. tarsalis to chemicals from habitats containing mosquitofish are complex and the origin of the semiochemicals present in the Gambusia-exudate water needs to be elucidated.

ABSTRAK  Latar belakang: Demam Berdarah Dengue (DBD) disebabkan oleh virus Dengue dapat menyebabkan kematian. Pencegahan DBD yang dianggap paling tepat adalah Pemberantasan Sarang Nyamuk (PSN). Penelitian ini bertujuan untuk mengetahui pengaruh pelatihan pengendalian vektor Demam Berdarah pada siswa sekolah dasar terhadap Maya Index di Majalengka. Metode: Penelitian ini menggunakan desain quasi experiment (pretest-posttest control group design). Sebanyak 4 sekolah terpilih sebagai kelompok intervensi dan 4 sekolah lainnya sebagai kontrol. Subyek penelitian adalah siswa kelas IV-VI yang terdiri dari 171 siswa pada kelompok intervensi dan 163 pada kelompok kontrol. Instrumen yang digunakan adalah formulir pemantauan jentik berkala. Hasil: Jumlah rumah dengan kategori Maya Index tinggi berkurang dari 27,5% menjadi 9,4%. Terjadi penurunan angka BRI kategori tinggi pada kelompok intervensi dari 20,5% menjadi 1,8%. Pada kelompok kontrol tidak terjadi penurunan angka BRI kategori tinggi (22,1%), sebaliknya terjadi penurunan kategori rendah dari 34,4% menjadi 3,7%. Tidak terjadi penurunan angka HRI pada kelompok intervensi maupun kontrol. Kesimpulan: Pelatihan pengendalian vektor Demam Berdarah dapat menurunkan nilai BRI dan Maya Index, tetapi tidak berpengaruh terhadap nilai HRI. Tidak adanya perubahan nilai HRI menunjukkan bahwa kebersihan dan sanitasi lingkungan merupakan faktor yang berpengaruh terhadap probabilitas kejadian demam berdarah. Kata Kunci : Demam Berdarah, Maya Index, pelatihan, pengendalian vektor   ABSTRACT Background: Dengue Hemorrhagic Fever (DHF) caused by Dengue virus could cause death. The most appropriate prevention of Dengue is eradication of mosquito nests (PSN). This study aims to determine the effect of Dengue vector control training on elementary students towards Maya Index in Majalengka. Method: This study used quasi-experimental design (pretest-posttest control group design). A total of 4 schools were selected as intervention groups and 4 other schools as controls. The subjects were students in grades IV-VI consisting of 171 students in the intervention group and 163 in the control group. The instrument used was periodic larva monitoring form. Results: The number of houses with a high Maya Index category in the intervention group decreased from 27.5% to 9.4%. There was a decrease in the high BRI category in the intervention group from 20.5% to 1.8%. In the control group, there was no decrease in the high BRI category (22.1%), on the contrary, there was a decrease in the low category from 34.4% to 3.7%. There was no decrease in HRI rates both of intervention or control groups. Conclusion: Dengue Fever vector control training could decrease the value of BRI and Maya Index, but does not affect the value of HRI. The absence of changes in HRI  indicate that environmental hygiene and sanitation are factors that influence the probability of dengue fever occurrence. Keywords: Dengue Hemorrhagic Fever, Maya Index, training, vector control
