      Abstract
      Mentimun merupakan salah satu tanaman hortikultura yang banyak dikonsumsi dan dibudidayakan di Indonesia. Serangan trips dan lalat buah dapat mengganggu budidaya tanaman mentimun. Oleh karena itu, perlu dilakukannya pengendalian. Salah satu pengendalian yang efektif yaitu menggunakan insektisida. Penelitian ini bertujuan mengetahui perkembangan populasi Thrips spp. dan intensitas serangan lalat buah (Bactrocera sp.) pada tanaman mentimun yang diberi bio-insektisida dengan bahan aktif Bacillus thuringiensis, insektisida nabati dengan bahan aktif ekstrak daun dan biji mimba, dan insektisida sintetik dengan bahan aktif lambda sihalotrin dan tiametoksam. Pengamatan populasi trips dilakukan dengan menghitung jumlah populasi pada tanaman contoh, sedangkan pengamatan lalat buah dilakukan dengan menghitung jumlah buah panen yang terserang pada tanaman contoh. Populasi Thrips spp. dan intensitas serangan lalat buah (Bactrocera sp.) pada tanaman mentimun yang diberi perlakuan bio insektisida bahan aktif Bacillus thuringiensis, insektisida nabati bahan aktif ekstrak daun dan biji mimba, dan insektisida sintetik bahan aktif lambda sihalotrin dan tiametoksam lebih rendah dibandingkan kontrol. Insektisida sintetik dengan bahan aktif lambda sihalotrin dan tiametoksam paling efektif digunakan untuk menekan populasi Thrips spp. dan intensitas serangan lalat buah (Bactrocera sp.)
       
      Cucumber is one of the most widely consumed and cultivated horticultural crops in Indonesia. The attacks by thrips and fruit flies can disrupted the cultivation of cucumber plants. Therefore, it is necessary to control them. One effective control is using insecticides. This research aims to determine the population development of Thrips spp. and the attacks intensity of fruit flies (Bactrocera sp.) on cucumber plants treated with bio-insecticide with active ingredient Bacillus thuringiensis, botanical insecticide with active ingredient neem extracts, and synthetic insecticide with active ingredients lambda cyhalothrin and thiamethoxam. Observations of thrips population were made by counting amount of nymphs and adult populations on sample plants, while fruit flies observations were made by counting the number of infested harvest fruits on sample plants. The population of Thrips spp. and the attacks intensity of fruit flies (Bactrocera sp.) on cucumber plants treated with bio-insecticides with active ingredients Bacillus thuringiensis, botanical insecticides with active ingredients neem extracts, and synthetic insecticides with active ingredients lambda cyhalothrin and thiamethoxam were lower than the control. Synthetic insecticides with active ingredients lambda cyhalothrin and thiamethoxam were most effective in suppressing population of Thrips spp. and attacks intensity of fruit flies (Bactrocera sp.)
