Nadeak, Budi Yosafat (2018) Tungau: Kelimpahan Pada Tanaman Pepaya Di Lahan Monokultur Dan Tumpangsari. Sarjana thesis, Universitas Brawijaya.
Abstract
Tungau merupakan salah satu jenis hama pada tanaman pepaya yang dapat mengakibatkan penurunan produktivitas. Tungau fitofag dari Famili Tetranychidae merupakan jenis tungau yang paling sering di temukan menyerang tanaman pepaya. Pengendalian hama tanaman dengan penerapan pengendalian hama terpadu (PHT) diharapkan mampu mengurangi dampak buruk serangan tungau fitofag. Penelitian tentang tungau fitofag dan tungau predator serta kelimpahannya pada tanaman pepaya varietas California pada lahan monokultur dan tumpangsari belum banyak dilakukan. Pengendalian tungau pada pertamanan pepaya varietas California pada lahan monokultur dan tumpangsari membutuhkan informasi dasar berupa jenis tungau dan kelimpahannya. Dengan diketahuinya tungau fitofag dan tungau predator serta populasinya diharapkan bisa digunakan dalam penyusunan strategi pengendalian tungau pada tanaman pepaya dan mencegah terjadinya kerusakan tanaman pepaya dan menurunkan hasil produksi. Tujuan penelitian ini adalah untuk mengkaji jenis tungau predator dan tungau fitofag serta kelimpahan populasinya pada tanaman pepaya varietas California di lahan monokultur dan tumpangsari. Penelitian dilakukan di lahan pepaya monokultur dan tumpangsari milik petani Desa Rembun dan Desa Talok Kecamatan Dampit Kabupaten Malang. Setiap lahan dipilih 25 tanaman pepaya secara acak dan setiap tanaman diambil dua daun contoh yaitu daun muda dan tua. Pengambilan daun contoh dilakukan setiap minggu mulai bulan April sampai Juni. Setiap daun contoh diamati semua tahap kehidupan tungau, dihitung, dicatat dan diuji dengan uji T dan uji korelasi Pearson. Dari hasil penelitian ditemukan tungau fitofag Tetranychus urticae, Panonychus citri, Brevipalpus phoenicis dan tungau predator Neoseiulus fallacis. Kelimpahan populasi tungau fitofag T. urticae, P. citri, B. phoenicis dan tungau predator N. fallacis pada kedua pola tanam adalah sama. Rata-rata populasi tungau T. urticae pada lahan monokultur dan tumpangsari adalah 162,88 individu; 148,13 individu per lahan, rata-rata populasi P. citri adalah 120,13 individu; 82,88 individu per lahan dan rata-rata populasi B. phoenicis adalah 9,75 individu; 3,75 individu per lahan. Sedangkan rata-rata populasi tungau predator N. fallacis adalah 26,88 individu; 24,38 individu per lahan. Pada penelitian ini, populasi tungau hanya ditemukan pada permukaan daun bagian bawah. Dari hasil penelitian ini, sebanyak 33,78%; 30,49% daun pepaya di lahan monokultur dan tumpangsari di huni oleh tungau T. urticae, di ikuti oleh tungau P. citri sebanyak 29,46%; 27,86% dan tungau B. phoenicis sebanyak 5,14%; 2,35%. Fase telur banyak dijumpai tungau T. urticae (50,83%), P. citri (54,09%), B. phoenicis (51,79%) dan N. fallacis (43,41%).
English Abstract
Mites are a type of pest on papaya plants which can lead to a decrease in productivity. Phytophagic mites from the Tetranychidae Family are types of mites that are most commonly found attacked papaya plants. Plant pest control with the application of integrated pest control is expected to reduce the adverse effects of phytophagic mite attacks. Research on phytophagic mites and predatory mites and its abundance in California variety papaya plants on monoculture and intercropping land has not been widely carried out. Mites control in California papaya varieties on monoculture and intercropping land requires basic information in the form of mites and their abundance. With the knowledge of phytophagic mites and predatory mites and their populations, it is expected that they can be used in the formulation of mite control strategies in papaya plants and prevent the occurrence of papaya plant damage and reduce production. The purpose of this study was to examine the types of predatory mites and phytophagic mites and the abundance of the population in California variety papaya plants in monoculture and intercropping fields. The research was conducted in monoculture and intercropping papaya land owned by farmers of Rembun Village and Talok Village, Dampit District, Malang Regency. Each of the 25 papaya plants was chosen at random and each plant was taken by two sample leaves, young and old. Sampling is carried out every week from April to June. Each leaf sample was observed in all stages of mite life, calculated, recorded and tested by T test and Pearson correlation test. From the results found phytophagic mites Tetranychus urticae, Panonychus citri, Brevipalpus phoenicis and predatory mites Neoseiulus fallacis. The abundance of fitofag mites T. urticae, P. citri, B. phoenicis and N. fallacis predator mites in both cropping patterns are same. The average population of T. urticae mites on monoculture and intercropping land is 162.88 individuals; 148.13 individuals per land, the average population of P. citri is 120.13 individuals; 82.88 individuals per land and the average population of B. phoenicis was 9.75 individuals; 3.75 individuals per land. While the average population of N. fallacis predatory mites is 26.88 individuals; 24.38 individuals per land. In this study, mites populations were only found on the lower leaf surface. From the results, 33.78%; 30.49% of papaya leaves in monoculture and polyculture were inhabited by T. urticae mites, followed by P. citri mites as much as 29.46%; 27.86% and B. phoenicis mites as much as 5.14%; 2.35%. The egg phase was found in T. urticae mites (50.83%), P. citri (54.09%), B. phoenicis (51.79%) and N. fallacis (43.41%).
