Abstract

Jagung adalah komoditas unggulan Kabupaten Lampung Timur. Invasi hama Spodoptera frugiperda menjadi masalah serius dalam budidaya jagung. Sejak awal masuknya hama S. frugiperda pengendalian yang dilakukan oleh petani di Kecamatan Batanghari Nuban adalah dengan mengunakan insektisida berbahan aktif emamectin benzoat. Namun penggunaan bahan aktif yang sama dalam waktu yang cukup lama dapat mempercepat terjadinya resistensi. Berdasarkan laporan dari Penyuluh Pertanian Lapangan (PPL), beberapa desa di Kecamatan Batanghari Nuban telah mengalami resistensi emamectin benzoat. Berdasarkan hal tersebut dirasa sangat perlu dilakukan penyuluhan terkait pengendalian S. frugiperda yang efektif ramah lingkungan. Tujuan dari kegiatan ini adalah untuk memberikan solusi dalam pengendalian hama invasif S. frugiperda yang telah mengalami resistensi terhadap bahan aktif emamectin benzoate dengan menggunakan perangkap berferomon. Perangkap berferomon ini dapat mengendalikan populasi S. frugiperda dengan cara yang ramah lingkungan sehingga mengurangi kerusakan pada tanaman jagung dan juga mengurangi dampak negatif penggunaan insektisida. Dengan demikian dapat mengurangi kerugian secara ekonomi dan mendukung sistem pertanian yang berkelanjutan. Hasil dari kegiatan ini petani dapat menggunakan feromon untuk memerangkap imago jantan S. frugiperda, sehingga dapat menurunkan populasi hama pada pertanaman jagung. Dengan menggunakan petangkap berferomon, petani dapat mengurangi biaya pengendalian dengan insektisida. Selain itu, dampak negatif dari insektisida juga dapat dikurangi.

Abstract

Begomoviruses are a group of plant viruses belonging to the Geminiviridae family, persistently transmitted by the whitefly Bemisia tabaci, and pose a serious threat to horticultural crops in Lampung Province, Indonesia. These viruses infection symptoms such as mosaic, chlorosis, leaf curling, and stunted growth, with yield losses reaching up to 90%. The spread is exacerbated by intensive cultivation practices, the use of uncertified seeds, and tropical climates that favor high vector populations. This study explores the biological characteristics of Begomoviruses, their transmission mechanisms via vectors, and their high genetic variability due to frequent mutation and recombination. Several begomovirus species have been identified infecting key horticultural crops in Lampung, including Ageratum yellow vein virus (AYVV), Tomato yellow leaf curl Kanchanaburi virus (TYLCKaV), and Pepper yellow leaf curl Indonesia virus (PepYLCIV). In addition to vector transmission, some begomovirus species are also known to be seed-transmitted, expanding their epidemic potential. Integrated management strategies discussed in this article include the use of resistant varieties, biological and agronomic control of vectors, and the development of innovative approaches such as mild strain cross-protection. This review emphasizes the need for continuous monitoring and science-based sustainable strategies to mitigate the impact of Begomoviruses on food security and horticultural productivity in tropical regions such as Lampung.

Abstract

The rhinoceros beetle (Oryctes rhinoceros L.) (Coleoptera: Scarabaeidae) is a significant pest reported to attack nearly all coconut and oil palm plantations in Indonesia. Metarhizium sp., a well-known biological control agent, has broad-spectrum insecticidal properties due to its production of destruxin toxins, which are particularly toxic to O. rhinoceros. However, the effectiveness of dry-formulation bioinsecticides containing Metarhizium for controlling this pest has not yet been fully assessed. Therefore, this study was conducted to evaluate the potential of a dry-formulated Metarhizium sp. bioinsecticide to induce mortality in O. rhinoceros larvae. The research objectives were: 1) to assess the ability of the dry formulation bioinsecticide with Metarhizium as the active ingredient to induce mortality in O. rhinoceros larvae; 2) to determine the most effective dose of the dry formulation bioinsecticide with Metarhizium sp. for causing high mortality rates in O. rhinoceros. The study employed a Completely Randomized Design (CRD) with five treatments: 37.5 g (P1), 28.13 g (P2), 18.75 g (P3), and 9.38 g (P4) of Metarhizium sp., along with a control (P5). Each experimental unit consisted of a 1000 ml jar containing 500 g of coconut stem powder and five O. rhinoceros larvae, replicated five times with a total of 125 larvae. Analysis was conducted using the LSD test at a 5% significance level. Results indicated that the bioinsecticide was effective, with the most effective dose being 18.75 g, which resulted in 76.00% mortality.

Abstract

Biological control fungi can be stored and produced in the form of spores on a specific medium. For mass production, a large quantity of spores is required in a short amount of time. This study aims to determine the effect of medium S on the sporulation, spore viability, and pathogenicity of the fungi Beauveria bassiana, Metarhizium flavoviride, Purpureocillium lilacinum, and Trichoderma asperellum. There were two sets of experiments in this study. The first experiment tested the growth ability of fungal isolates on modified medium S in vitro. The second experiment tested the viability of the fungi that had been grown on the medium used in the previous experiment. The results showed that the type of fungus and the type of medium affected growth and spore production but did not influence spore viability. Among the biological agents, there appears to be mutual inhibition, though this inhibition does not seem to affect their ability to cause the death of the test insects. The consortium of biological agents resulted in a higher mortality rate of the test insects compared to single-agent applications.

Abstract

The rhinoceros beetle, Oryctes rhinoceros, is a major pest on coconut and oil palm plants, attacking both in replanting areas and directly in farmers' fields. The O. rhinoceros beetle (Coleoptera: Scarabaeidae) holds the most important position as a pest of coconut plants, both in terms of its damaging ability, distribution, population stability, and year-round population size, and is widely recognized by coconut farmers. The use of microorganisms as biological agents is part of biological control efforts. One biological agent widely used as a bioinsecticide and proven to be quite effective is the entomopathogenic fungi group, such as Beauveria bassiana. The objectives of this research are as follows: 1). To determine the ability of a commercial product containing B. bassiana as an active ingredient to cause mortality in O. rhinoceros larvae; 2) To identify the effective dose that can cause high mortality in O. rhinoceros. This study used a Completely Randomized Design (CRD) with five treatments tested, namely: P1: 37.5 g B. bassiana; P2: 28.13 g B. bassiana; P3: 18.75 g B. bassiana; P4: 9.38 g B. bassiana; P5: control. Each treatment was repeated five times, and each replicate consisted of five samples, resulting in 25 experimental samples or a total of 125 O. rhinoceros larvae. Further analysis was conducted using the LSD test at a 5% significance level. Based on the research results, the commercial product containing B. bassiana as an active ingredient was able to cause mortality in O. rhinoceros. The most effective dose for controlling O. rhinoceros larvae was treatment 3, with a dose of 18.75 g, yielding an average mortality rate of 72%.

Abstract

Rice is an important food crop and a staple food source in Indonesia. The challenges in increasing rice production are not only caused by weather factors (drought, flooding) but also by pest and plant disease attacks. One of the rice pests that causes significant losses is the brown planthopper (BPH). Insecticides with the active ingredient imidacloprid have been known to effectively control brown planthoppers. However, in recent times, resistance to this insecticide has developed in brown planthoppers. This study aims to investigate the possible presence of symbiotic bacteria in brown planthoppers that can degrade imidacloprid insecticide as their carbon source. The steps taken include biochemical tests and testing the growth ability on media containing imidacloprid. The results of the tests showed that the bacterial isolates tested were unable to degrade the imidacloprid insecticide.
