Abstract

Arthropoda Musuh alami merupakan organisme yang ditemukan di alam yang dapat membunuh serangga sekaligus, melemahkan serangga, sehingga dapat mengakibatkan kematian pada serangga hama. Penelitian ini bertujuan untuk mengetahui komposisi, kelimpahan dan tingkat keanekaragaman Arthropoda musuh alami pada modifikasi habitat lahan tembakau Nicotiana tabacum L. menggunakan insectary plant Helianthus annuus, serta tren kelimpahan musuh alami terhadap herbivora Metode yang digunakan yaitu dengan modifikasi habitat lahan tembakau menggunakan insectary plant Helianthus annuus membentuk perimeter mengelilingi main crop tanaman tembakau. Parameter yang dianalisa yakni kelimpahan, keanekaragaman spesies, kesamaan komunitas Morisita-Horn serta tren kelimpahan arthropoda musuh alami dengan herbivora. Indeks Shannon - wiener nilai keanekaragaman di kedua lahan pada setiap fase pertumbuhan tembakau adalah tergolong tinggi. Sedangkan Indeks kesamaan komunitas Morishita Horn antara kedua Lahan pada fase vegetatif, fase generatif, fase reproduktif didapatkan nilai indeks kesamaaan komunitas mendekati 1 berarti komunitas tersebut mempunyai kemiripan spesies yang sama. ============================================================================================================== Natural enemies Arthropod is an organism found in nature that can kill insects at once, weakens the insects, which can lead to death in pest insects. This study aims to determine the composition, abundance and diversity of arthropods level of natural enemies on land habitat modification Nicotiana tabacum L. tobacco use insectary plant Helianthus annuus, and trends abundance of natural enemies against herbivores The method used is a modification of wetland habitat tobacco use insectary plant Helianthus annuus formed around the perimeter of the main crop of tobacco plants. Parameters analyzed the abundance, species diversity, community similarity Morisita-Horn and abundance trends with herbivorous arthropod natural enemies. Shannon - wiener Index diversity in both land value at every phase of growth of tobacco is relatively high. While Morisita Horn community similarity index between the two of Land in the vegetative phase, the generative phase, reproductive phase obtained index value close to 1 it’s means the community and the similarities almost have the same species.
