Abstract

Tanaman krisan merupakan salah satu tanaman hias yang sudah dikembangkan oleh petani di daerah Kakaskasen Kota Tomohon. Serangga hama menjadi salah satu penghambat dalam upaya meningkatkan produksi tanaman potong bunga krisan. Banyak petani belum memahami jenis-jenis hama yang ada di pertanaman krisan. Penelitian ini bertujuan untuk untuk mengidentifikasi jenis-jenis hama yang menyerang tanaman krisan di desa Kakaskasen II Kota Tomohon dan untuk mengamati gejala serangan hama pada tanaman krisan. Hasil penelitian menunjukkan terdapat tiga spesies utama hama yang menyerang krisan yaitu : Liriomyza spp., Thrips spp. dan Aphis spp. Gejala serangan Liriomyza adanya gejala gorokan larva yaitu : terowongan dalam daun, melingkar-lingkar di dalam epidermis daun. Hama Thrips spp. memperlihatkan gejala pada bunga yang terserang menunjukkan gejala seperti garis-garis yang memanjang yang berwarna coklat keperakanyang merupakan akibat dari alat mulut menusuk mengisap dari hama tersebut yang mengisap pada bunga. Gejala serangan Aphis sp. yaitu tanaman menjadi tumbuh agak kerdil, warna daun berubah menjadi kekuningan, dan tidak normal.Pengendalian hama tersebut di atas dapat dilakukan dengan menggunakan pengendalian hama terpadu antara lain : monitoring keberadaan hama, penggunaan varietas resisten, mengeluarkan tanaman atau bagian tanaman yang terserang, penggunaan perangkap kuning berperekat, memanfaatkan musuh alami dan pengendalian kimia dengan dosis yang sesuai.
