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.

Abstract

Spodoptera frugiperda (FAW), or fall armyworm, is a major invasive pest that attacks corn crops in various tropical and subtropical regions. In recent decades, the global spread of FAW has been accelerated by international trade and climate change. In Indonesia, the presence of this pest was first reported in 2019 in West Sumatra, with attacks spreading to various other areas. The FAW life cycle includes four stages (eggs, larvae, pupae, and imago) with significant levels of plant damage, especially in the larval stage.Various con- trol strategies have been implemented, including integrated pest management (IPM) approaches, such as the use of biological agents (Beauveria bassiana and Metarhizium anisopliae), push-pull techniques, and crop rotation. In addition, the development of pest-resistant corn varieties is an important alternative. Recent re- search has identified two genetic lines of FAW, namely corn and rice lines, which show differences in host preference and resistance to insecticides.This study highlights the need for further development of ecologi- cally based strategies, including exploration of local parasitoids and effective bioinsecticide formulations. In addition, genetic and microbiota analyses offer new potential in understanding FAW population dynamics and its control. These results are expected to be the basis for sustainable pest management in Indonesia and other regions.

Abstract

Kelompok Tani Mekar Sari di Desa Hajimena, Kecamatan Natar, Kabupaten Lampung Selatan, menghadapi tantangan berupa serangan hama dan penyakit tanaman yang berdampak pada penurunan hasil panen. Tingginya ketergantungan terhadap pestisida kimia memotivasi diadakannya pelatihan pembuatan pestisida nabati sebagai alternatif pengendalian yang ramah lingkungan. Kegiatan pengabdian ini bertujuan untuk mengenalkan jenis tanaman yang dapat digunakan sebagai pestisida nabati dan melatih petani dalam membuat serta mengaplikasikannya. Metode yang digunakan mencakup penyuluhan dan praktik langsung. Pada sesi pertama, materi yang disampaikan meliputi konsep dasar, manfaat, dan langkah pembuatan pestisida nabati. Pada sesi kedua, dilakukan praktik pembuatan pestisida nabati berbahan dasar daun nimba (Azadirachta indica), yang melibatkan 23 petani sebagai partisipan. Hasil pengabdian menunjukkan peningkatan pengetahuan petani terkait bahaya pestisida kimia, penggunaan pestisida nabati, serta cara pengendalian hama dan penyakit. Berdasarkan evaluasi, persentase pemahaman petani tentang pestisida nabati meningkat sebesar 56,52%. Kegiatan ini tidak hanya memberikan solusi praktis bagi petani, tetapi juga menjadi langkah awal menuju praktik pertanian yang lebih berkelanjutan dan ramah lingkungan.

Abstract

Spodoptera frugiperda is a highly polyphagous pest capable of causing up to 100% yield loss in maize. This study aimed to evaluate the effects of endophytic Beauveria bassiana applied through root drench, seed treatment, and foliar spray on the severity of larval feeding damage and egg parasitization by S. frugiperda. The B. bassiana isolate (JgSPK) used in this study was molecularly identified and deposited in GenBank (acc. no. MZ356494). Results indicated that among the three inoculation methods, seed treatment resulted in the highest endophytic colonization, followed by soil drench and foliar spray. Feeding on leaves colonized by the fungus increased larval mortality and resulted in abnormal pupation. Seed treatment showed the greatest potential in reducing larval feeding severity compared with foliar spray and soil drench applications. However, none of the inoculation methods significantly affected egg parasitization rates. Overall, endophytic B. bassiana reduced larval attack severity but did not influence egg parasitization, indicating compatibility with egg parasitoids. Further research is recommended to evaluate potential effects on larval parasitoids.
