Abstract

Spodoptera frugiperda has a high potential to cause crop failure in corn plantations. However, information on this pest attack is still very limited in Central Sulawesi and there have been no reports of this pest attack in Banggai Regency. The purpose of this study was to analyze the biology, infestation and natural enemies of S. frugiperda in Banggai Regency. This study was conducted in corn plantations owned by the community in Boras village, Sepe village and Dolom village. Observation of the biology of S. frugiperda was done by calculating the time needed at each stage. Observation of infestation was done by observing sample plants that were attacked and observing natural enemies in the form of parasitoids by taking samples of eggs and larvae then observing the parasitoids that appeared, in observing predators by using pitfall traps to trap insects on the ground which were then identified and in observing entomopathogenic fungi by taking samples of infected S. frugiperda larvae in the field and then identifying them. The results showed that the life cycle of S. frugiperda lasts approximately 45 days. The infestation of S. frugiperda is considered very high with an average infestation in the last observation in Boras Village of 84%, Sepe Village of 76% and Dolom Village of 88%. 5 types of natural enemies were found, namely 1 type of egg parasitoid (Telenomus sp.), 1 type of larval parasitoid (Megaselia sp.), 2 types of predators (Lycosa sp. and Forficula sp.), and 1 type of entomopathogenic fungus (Metarhizium sp.). ABSTRAK Spodoptera frugiperda sangat berpotensi menimbulkan gagal panen pada pertanaman jagung. Akan tetapi, informasi mengenai serangan hama ini masih sangat sedikit di Sulawesi Tengah dan belum ada laporan mengenai serangan hama tersebut di Kabupaten Banggai. Tujuan penelitian ini untuk menganalisis biologi, infestasi dan musuh alami S. frugiperda di Kabupaten Banggai. Penelitian ini dilaksanakan di lahan pertanaman jagung milik masyarakat di Desa Boras, Desa Sepe dan Desa Dolom. Pengamatan biologi S. frugiperda yaitu dengan menghitung waktu yang dibutuhkan pada setiap stadianya. Pengamatan infestasi dilakukan dengan cara mengamati tanaman sampel yang terserang dan pengamatan musuh alami berupa parasitoid yaitu dengan mengambil sampel telur dan larva kemudian diamati parasitoid yang muncul, pada pengamatan predator yaitu dengan menggunakan pitfall-trap untuk memerangkap serangga permukaan tanah yang kemudian diidentifikasi dan pada pengamatan cendawan entomopatogen yaitu dengan mengambil sampel larva S. frugiperda yang terinfeksi di lapangan kemudian diidentifikasi. Hasil penelitian menunjukkan bahwa siklus hidup S. frugiperda berlangsung kurang lebih selama 45 hari. Infestasi S. frugiperda tegolong sangat tinggi dengan rata-rata infestasinya pada pengamatan terakhir yaitu di Desa Boras sebesar 84%, Desa Sepe sebesar 76% dan Desa Dolom sebesa 88%. Ditemukan 5 jenis musuh alami yaitu 1 jenis parasitoid telur (Telenomus sp.), 1 jenis parasitoid larva (Megaselia sp.), 2 jenis predator (Lycosa sp. dan Forficula sp.), dan 1 jenis cendawan entomopatogen (Metarhizium sp.).

Abstract

Biological control using endophytic fungi is one solution that can be applied to prevent or reduce S. frugiperda pest attacks, especially in corn plantations. The purpose of this study was to determine the effect of pathogenicity test of endophytic fungus Aspergillus sp. from the exploration results that can cause mortality in Spodoptera frugiperda. This study with three stages, namely the first stage of taking test samples of S. frugiperda in corn fields and the second stage of colonization testing for one of the endophytic fungi obtained from the results of exploration of corn plants, then in the third stage a pathogenicity test was carried out using the completely randomized design (CRD) method using endophytic fungus Aspergillus sp and tested on three stages of S.frugiperda as a treatment with a spore density of 108/ml. The results of the study showed that the infection rate at the larval stage of S.frugiperda reached 55% up to a mortality rate of 52.5%, then observations at the infected pupal stage of S.frugiperda reached 27.5% and the mortality rate was up to 30% to cause mortality of 32.5% as well as at the observation stage infected imago were not much different from the results of observations of the pupal stage.
