Abstract

Dysmicoccus neobrevipes dari famili Pseudococcidae merupakan hama penting dengan distribusi luas di Indonesia. Serangan hama kutu putih secara ekonomi dapat merusak komoditas pisang asal Maluku Utara. Keberadaan kutu putih di pertanaman sangat beragam dan melimpah. Kutu putih dapat menimbulkan gejala kerusakan pada seluruh bagian tanaman terutama pada buah. Tujuan penelitian adalah mempelajari karakteristik morfologi D. neobrevipes dengan kutu putih jenis lain pada komoditas pisang. Sampel spesimen diambil secara purposive sampling di lima pasar sentra pisang meliputi pasar Bastiong (Pulau Ternate), pasar Jailolo (Halmahera Barat), pasar Tobelo (Halmahera Utara), pasar Labuha (Pulau Bacan), dan Pasar Sanana (Kepulauan Sula). Preparasi spesimen dan identifikasi menggunakan metode Heinz yang dimodifikasi. Variabel pengamatan morfologi berupa bentuk tubuh dan keberadaan organ spesifik kutu putih. Hasil menunjukkan D. neobrevipes berbentuk oval, mempunyai 17 cerarri, sepasang antena, 2–3 discoidal pore, anterior ostiole dan posterior ostiole berkembang baik, 2–4 conical seta, 3–7 auxilary seta, sekelompok trilocular pore, circulus berkembang sempurna, terdapat translucent pore pada tibia dan femur tungkai belakang, oral coral tubular duct bertipe besar dan kecil, dorsal seta lebih pendek dari anal ring seta, multicolar pore terdapat di tengah, anal ring terdiri 6 seta dan anal cerarri terdiri 2 conical seta.

Abstract

Sexava coriacea is the most important pests on coconut in North Maluku. The insects known as coconut treehoppers cause damage to foliar defoliation. S. coriacea attacked coconut crops in Sula-Mangoli Islands first reported by C Willemse in 1930. The reports of the pest monitoring program over the last ten years showed symptoms of moderate attack levels on the leaves which could be controlled. In 2022, there were another pests outbreaks in Halmahera and Sula Islands that inflicted serious leaflets damage on coconut. The research aimed to study the development and distribution of S. coriacea on coconut plantations in the Maluku Islands. The study was used a purposive sampling method in the planting area which showed symptoms of an attack and the presence of the pest target. The pest specimens obtained were identified by morphological characteristics. Leaf damage level obtained was further developed with five categories; healthy, mild, moderate, severe, and very severe. The results showed S. coriacea found in Galela, Sahu, Bacan, and Sanana. Damage rates of coconut crops were calculated in North Halmahera reached 76-100%; West Halmahera reached 26-50%; South Halmahera reached 1-25%; and Sula Islands reached 51-75%.
