Uji Efikasi Repelen “X” terhadap Nyamuk Aedes Aegypti, Culex Quinquefasciatus dan Anopheles Aconitus di Laboratorium

ENGLISHA single dose of repellent (1.5 gram/600 cm2) was tested against mosquitoes of Aedes aegypti, Culex quinquefasciatus and Anopheles aconitus in the laboratory. After 6 hours, the protective rates of the repellent less than 90% (efficacy criterion) against the three mosquitoes species above. This results indicated that the repellent on the dosage of 1,5 grams/600 cm2 ineffective so that repetition test should be considered by using different formula as well as doses and applications.INDONESIASuatu repelen dosis tunggal (1,5 gram/600 cm2) telah diuji daya proteksinya terhadap nyamuk Ae. aegypti, Cx. quinquefasciatus dan An. aconitus di laboratorium. Pada pengamatan setelah 6 jam, daya proteksi repelen terhadap ketiga spesies nyamuk tersebut berturut-turut sebesar 63,8%; 73% dan 69% atau kurang dari 90% (kriteria efikasi). Hal itu berarti bahwa pada dosis/konsentrasi 1,5 gram per 600 cm2, repelen tidak efektif sehingga perlu dipertimbangkan untuk dilakukan uji ulang menggunakan repelen dengan formulasi berbeda pada berbagai dosis dan aplikasi

USAha Penanggulangan Vektor Malaria dan Filariasis melalui Penyuluhan Kesehatan di Sekolah Dasar di Kecamatan Wulanggitang, Kabupaten Flores Timur Nusa Tenggara Timur

A study to evaluate the effectiveness of school health education for mosquito borne diseases vector control program was conducted in East Flores Regency, East Nusa Tenggara Province. The method of study include education program for the teachers and 4th through 6th grade students from 2 primary schools and another school in the area was chosen as control. The evaluation was made through responses obtained from the questionaires given before and after the education program for malaria and filariasis regarding their sign, symptoms, the vector and prevention. The results show that there are 3,82% and 4,10% increase in knowledge about malaria and filaria respectively after the education program. This means the education material was well accepted. Although there was an overall increase in knowledge about malaria, no similar response was noted for filariasis. Thus the education material for filariasis should be improved. The result of the study suggest that a continous education program for malaria and filariasis should be incorporated into the regular School Health Education curicullum in the endemic areas

Fauna Anopheles di Daerah Endemis Malaria Kabupaten Jepara Jawa Tengah

During the operational - scale field trials for malaria vector control in Jepara regency, an intensive mosquito collection was carried out in 8 villages of 5 subdistrict, 1983-1986. The mosquito collections consisted of landing on man indoor and outdoor, night resting in cattle shelters, daytime resting indoor and outdoor. Ten Anopheles spp. i.e. Anopheles aconitus, An. annularis, An. barbirostris, An. indefinitus, An. subpictus, An. tesselatus, An. minimus and An. vagus were caught. Among these mosquito, An. aconitus as the main malaria vector was caught predominantly landing on man and resting outdoor, followed by An. vagus. Other species were caught in small numbers

A Village-scale Trial of Alphamethrin (Oms-3004) Against the Ddt Resistant Malaria Vector Anopheles Aconitus in Central Java

Suatu uji coba tingkat pedesaan insektisida alphamethrin (OMS-3004) telah dilakukan untuk me­nanggulangi vektor malaria Anopheles aconitus. Aplikasi dilakukan dengan penyemprotan seluruh din­ding rumah (total coverage) dosis 100 mg/m2 di daerah kecamatan Boja, kabupaten Kendal, Jawa Te­ngah, pada tahun 1985. An. aconitus di daerah tersebut sudah resisten terhadap DDT. Hasil penilaian dengan parameter nyamuk yangmenggigit orang di dalcan dan di luar rumah, hinggap di kandang pada malam hari, hinggap di dalam dan di luar rumah pada pagi hari, menunjukkan bahwa insektisida ini efektif selama 6-8 minggu. Umur residu (residual effect) efektif (kematian An. aconitus 50%) selama 4 minggu pada permukaan kayu. Pengaruh fumigasi sangat rendah, hanya 8,69% An. aconi­tus mati dua minggu setelah penyemprota

Perbandingan Efektivitas Pengabutan dan Penaburan Malathion 5% dalam Upaya Pengendalian Vektor Penyakit Tular Rodensia

A trial of thermal fogging using malathion 5% EC against fleas was conducted two cycles with an interval of two weeks application, in the rodent borne disease enzootic areas, in Boyolali, Central Java. The objective of the trial is to determine the efficacy of malathion 5% EC applied by thermal fogging compared to dusting method by Fanara, et al (1979). Result of the trial showed that the crude index flea was reduced 67.4% - 83.6% for 14 days, compared to 65% - 94% reduction for 120 days by dusting application

Japanese Encephalitis Virus Isolated From Seven Species Of Mosquitoes Collected At Semarang Regency, Central Java

Suatu penelitian telah dilakukan untuk mengisolasi arbovirus dari nyamuk yang ditangkap dari rumah penduduk dan kandang ternak desa Susukan, kecamatan Ungaran, kabupaten Semarang. Pada periode penelitian yang dilakukan selama 2 tahun, isolasi virus hanya didapatkan pada bulan Januari dan Februari. Virus Japanese encephalitis (JEV) adalah satu-satunya virus yang dapat diisolasi. Mayoritas isolat JEV (72%) berasal dari nyamuk yang ditangkap di kandang ternak. Isolat JEV ini berusai dari 7 spesies nyamuk dengan frekuensi Culex quinquefasciatus yang paling tinggi (11.5%). Empat vektor JEV baru yang potensial di Indonesia adalah Cx.bitaeniorhynchus, Cx.quinquefasciatus, Anopheles kochi dan Armigeres subalbatus. Ini adalah laporan pertama tentang isolasi JEV dari An.kochi dan Ar.subalbatus di Asia
