Peta status kerentanan Aedes aegypti (Linn.) terhadap insektisida cypermethrin dan malathion di Jawa Tengah

<p><strong><em>Abstract</em></strong><strong><em>.</em></strong> <em>Th</em><em>e increasing prevalence of Dengue Haemmorhaegic Fever (DHF) is spread through all districts in Indonesia. Dengue Haemorrhagic Fever Control such as vector control, focussing to break DHF transmission. Some research about </em>Ae. aegypti<em> resistance had been done in DHF endemic area in Central Java. Resistance status of </em>Ae. aegypti<em> against insecticide programme promoted by health government in middle and low endemic DHF in Central Java was investigated in this research. Sample collected from 100 houses selected purposively in every village, at every District there were 3 villages selected. Samples consisted of egg, larvae and adult mosquitoes of </em>Ae. aegypti<em>, and reared to get F1. Resistance test of </em>Ae. aegypti<em> done by using WHO susceptibility impregnated paper test procedure. This research showed that </em>Ae. aegypti<em> in all research location had been resistance to malathion 0.8% with mosquitoes mortality average between 13.80%-61.67% and almost all sample is resistance to cypermethrin 0.05% with mosquitoes mortality between 10.00%-63.33% except with sample from Banjarnegara District which has mosquitoes mortality of 84.20%. The conclusion of this research is that </em>Ae. aegypti<em> in all research location had been resistance to malathion. Almost all location resistant to cypermethrin except Banjarnegara District sample which has tolerance level.</em><em> </em></p> <p><em> </em></p> <p><strong><em>Keywords</em></strong><em>: </em><em>resistance, Central Java, malathion, cypermethrin</em></p><p><em><br /></em></p> <p><strong> </strong></p> <p><strong> </strong></p> <p><strong>Abstrak</strong>. Persebaran DBD semakin meluas di semua kabupaten/kota. Pengendalian DBD terutama ditujukan untuk memutus rantai penularan, antara lain dengan pengendalian vektornya. Beberapa penelitian resistensi <em>Aedes aegypti</em> telah dilakukan di wilayah endemis DBD. Status resistensi <em>Ae. aegypti</em> terhadap insektisida yang digunakan program kesehatan di daerah endemis sedang dan rendah di Jawa Tengah merupakan hal yang akan dikaji dalam penelitian ini. Pengumpulan sampel uji dari 100 rumah per desa yang dipilih secara purposif pada tiga desa/kelurahan dengan masalah DBD pada setiap Kabupaten terpilih di Jawa Tengah. Sampel berupa larva, telur dan nyamuk dewasa yang selanjutnya dipelihara untuk memperoleh F1. Uji resistensi pada <em>Ae. aegypti</em> dewasa dilakukan dengan menggunakan impregnated paper dengan mengacu pada standar WHO. Hasil menunjukkan <em>Ae. aegypti</em> di lokasi penelitian telah resisten terhadap malathion 0,8% dengan kematian berkisar antara 13,80%-61,67%. Hampir semua telah resisten terhadap cypermethrin 0,05% dengan kisaran 10%-63,33%, kecuali sampel dari Kabupaten Banjarnegara masih toleran dengan kematian 84,20%. Sembilan kabupaten pada lokasi survei di Jawa Tengah telah resisten terhadap malathion,delapan kabupaten telah resisten cypermethrin, satu kabupaten yaitu Banjarnegara masih toleran terhadap cypermethrin.</p> <p><strong>Kata Kunci</strong>: resistensi, Jawa Tengah, malathion, cypermethrin
