Salah satu upaya untuk mengurangi kasus DBD adalah dengan pengendalian vektor DBD dengan larvisida. Temephos merupakan salah satu insektisida yang telah digunakan lebih dari 30 tahun dan berfungsi mengendalikan larva vektor. Penggunaan temephos yang tidak sesuai aturan dapat menyebabkan penurunan kerentanan pada vektor DBD.  Tujuan penelitian ini  adalah untuk  menilai  status  kerentanan larva Aedes aegypti di tiga kecamatan di Kota Padang. Penelitian ini menggunakan post  test  only  with  control  group design. Telur diambil dan dipelihara di laboratorium hingga mencapai larva instar III/IV. Uji kerentanan untuk temephos dilakukan berdasarkan standar WHO. Hasil penelitian menunjukkan pada Kecamatan Kuranji, kematian larva pada konsentrasi 0,005 mg/L sebesar 10%, 0,01 mg/L sebesar 45%, 0,02 mg/L sebesar 86%, dan pada konsentrasi 0,03 mg/L sebesar 100%. Pada Kecamatan Koto Tangah, kematian larva pada konsentrasi 0,005 mg/L sebesar 24%, 0,01 mg/L sebesar 48%, 0,02 mg/L sebesar 99%, dan pada konsentrasi 0,03 mg/L sebesar 100%. Pada Kecamatan Padang Timur pada konsentrasi 0,005 mg/L didapatkan kematian larva sebesar 12%, pada 0,01 mg/L sebesar 43%, pada 0,02 mg/L sebesar 99%, dan pada 0,03 mg/L sebesar 100%. Hasil uji One way-Anova adalah bermakna dengan nilai p<0,05 pada ketiga kecamatan dan LC99 sedikit diatas 0,02 mg/L. Simpulan penelitian ini adalah status kerentanan Aedes aegypti terhadap temephos di tiga kecamatan berkisar antara rentan dan toleran, belum mencapai resisten sehingga temephos masih dapat digunakan dalam pengendalian vektor DBD.
