The conservation of natural enemies through the use of refugia plants is an important strategy to enhance arthropod diversity and stability in rice ecosystems, but its effectiveness may vary across locations. This study aimed to evaluate the potential of several refugia plant species in increasing arthropod diversity in rice fields of South Solok Regency, Indonesia. The study was conducted from December 2024 to April 2025 in Nagari Lubuk Gadang, South Solok Regency. Arthropod sampling was performed using a D-VAC (vacuum sampler) and insect net. The experiment was arranged in a randomized block design with six treatments (Cosmos caudatus, Ageratum conyzoides, Portulaca oleracea, Celosia cristata, Tagetes erecta, control), in four replications respectively. Observations included species composition, abundance, and diversity indices. The results showed that refugia plants contributed to the suppression of pest populations and improved the stability of arthropod communities. A total of 9 orders, 32 families, and 44 species were recorded, comprising 1,167 individuals, with herbivores accounting for 71.55% of the total population. The dominant herbivores were Cicadulina bipunctata, Leptocorisa oratorius, and Nilaparvata lugens, which were generally more abundant in rice fields without refugia. Predator and parasitoid abundance tended to be higher in the rice fields surrounded by C. cristata and T. erecta. The highest arthropod diversity was recorded in plots with T. erecta (H’ = 3.02), low dominance (0.07) and high evenness (0.86). Therefore, C. cristata and T. erecta are recommended as refugia plants to support sustainable integrated pest management in rice fields of mid-altitude areas.

Formulating a stable para-menthane-3,8-diol (PMD) nanoemulsion requires a balanced ratio of active ingredients and surfactants. Increasing the active ingredient may improve efficacy but can reduce stability, while excessive surfactant levels may cause unwanted foaming during application. This study evaluates the use of a defoamer to improve nanoparticle stability and enhance the biological activity of the formulations against Spodoptera frugiperda. The research was conducted in two stages: (1) characterization of particle stability using the DLS method and (2) evaluation of insecticidal activity through the leaf-dip bioassay. Data were analyzed using ANOVA followed by the LSD test; LC50 and LC95 values were determined via Probit analysis using POLO PLUS. The addition of a defoamer significantly improved the physicochemical properties and performance of the PMD nanoemulsion. The formulation achieved a refined particle size of 202.2 nm and a PDI of 0.20, both within acceptable nanoparticle standards. At a concentration of 0.25%, the defoamer-enhanced formulation demonstrated superior biological efficacy, including a 0.07% increase in LC95 efficiency and 3.14% growth inhibition. The treatment reduced pupal formation and adult emergence by 8% and altered the sex ratio. The addition of a defoamer improves the physical properties of the nanoemulsion and its biological efficacy against Spodoptera frugiperda.

Spodoptera frugiperda is a major pest of maize that can cause substantial yield losses. This study aimed to develop dried solid formulations of entomopathogenic fungi, evaluate their stability during three months of storage, and assess their insecticidal activity against S. frugiperda larvae. Conidia of Beauveria bassiana, Metarhizium anisopliae, and Penicillium citrinum were separately formulated using compost, wheat flour, or rice flour as carriers. The formulations were stored for one, two, and three months and subsequently tested against first-instar larvae at a concentration of 1 × 1010 conidia mL-1 through topical application. All fungal formulations significantly reduced larval body weight and fecal production compared with the control (P<0.05). They also caused significantly higher larval mortality than the control (P<0.05). After one month of storage, larval mortality ranged from 59.33 to 76.67%. The B. bassiana formulation with compost as the carrier maintained relatively high insecticidal activity, causing 76.00%, 70.00%, and 59.33% mortality after one, two, and three months of storage, respectively. After three months of storage, this formulation also resulted in the lowest pupation percentage (40.67%) and adult emergence (20.00%). In addition, the fungal treatments reduced the number of eggs laid by surviving female adults. Overall, the dried solid formulation of B. bassiana with compost showed the most consistent insecticidal activity during storage and therefore has potential as a bioinsecticide candidate against S. frugiperda. Further formulation optimization is required to improve conidial stability and extend product shelf life.

The cassava lace bug (Hemiptera: Tingidae), an invasive pest from South America, has significantly threatened cassava ( Manihot esculenta ) cultivation in Indonesia. The study aimed to identify lace bug species and assess their impact on cassava in Lima Puluh Kota Regency, West Sumatra, Indonesia. Systematic random sampling was conducted across 15 locations in five sub-districts of Lima Puluh Kota Regency, West Sumatra. Population density was assessed at three leaf positions (upper, middle, lower) using 50 to 90 plants per location. Damage severity was evaluated using a 0–5 scale, and morphological identification confirmed species identity. The study results indicate that morphological identification confirmed Vatiga illudens as the species infesting cassava plants in Limapuluh Kota District. Two-way ANOVA revealed highly significant effects of leaf position (F₂,₄₅ = 53.576, p < 0.001, ηₚ 2 = 0.994), location (F₄,₃₀ = 82.31, p < 0.001), and their interaction (F₈,₃₀ = 30.19, p < 0.001) on population density. Clear vertical stratification was observed: lower leaves (129.69 ± 5.18 individuals/leaf) > middle leaves (80.97 ± 2.01) > upper leaves (25.79 ± 1.25). Akabiluru district showed the highest infestation levels (82.32 ± 0.58 individuals/leaf) compared to other locations. Nymph populations dominated lower and middle leaf positions, while adults were more abundant on upper leaves. All sites exhibited 100% plant infestation with moderate damage intensity (38.11–47.57%). The entomopathogenic fungus Lecanicillium lecanii was identified infecting lace bugs. This first record confirms V. illudens establishment in Sumatra with significant ecological impact, emphasizing the urgent need for integrated pest management and surveillance programs.

Palm oil-based surfactants have the potential to be used as botanical insecticide formulations that are environmental friendly. This study was aimed to obtain information on the potential of palm oil-based surfactants as substitutes of synthetic surfactants in the preparation of botanical insecticide formulations to control Spodoptera frugiperda in organic farming. The experiment consisted of two stages, namely the stability test (surfactant and formulation) and the second stages were to test the insecticidal activity of the formulation against the targeted insects. The method of stability tests was following the standards of Collaborative International Pesticides Analytical Council (CIPAC). The insecticidal activity test used the leaf immersion method with the observation parameters of larval mortality and larval development time. The relationship between treatments and larval mortality was analyzed using probit to determine the LC50 and LC95 values. The data obtained were analyzed for variance and continued with the Least Significant Different test at 5% level. This study showed that palm oil has potential as a surfactant in the Piper aduncum nanoemulsion formulation according to CIPAC standards and affected the mortality of S. frugiperda with LC50 concentration of 0.55 and LC95 of 2.95.

Magnaporthe oryzae-induced rice blast remains a critical threat to sustainable rice farming, causing extensive losses in many rice-producing regions worldwide. Due to increasing concerns about pesticide overuse and its impact on the environment and human health, alternative control methods are being actively explored. Nanotechnology has recently gained attention as a potential tool for sustainable disease management. This review summarises current progress in the use of nanomaterials—including metal and biopolymer nanoparticles, nanoemulsions, targeted delivery systems, and biosensors—for the detection and control of rice blast. Studies have reported that nanomaterials can reduce disease severity by up to 70% and improve rice yield by 10–20% under field or greenhouse conditions. The mode of action, effectiveness under field conditions, and possible integration into integrated pest management (IPM) programs are discussed. The selection of literature followed the PRISMA-P framework to ensure a systematic and transparent review process. Challenges such as biosafety, environmental risks, and regulatory issues are also addressed, with emphasis on green synthesis methods and the need for field validation before practical application.

Spodoptera frugiperda (J.E. Smith) (Lepidoptera: Noctuidae), commonly known as the Fall Armyworm (FAW), is an invasive pest that causes significant damage to maize crops across tropical regions. This study aimed to examine the status of FAW as a maize pest in West Sumatra, Indonesia, focusing on the relationship between infestation area and rainfall. Monthly rainfall data were obtained from the Meteorology, Climatology, and Geophysics Agency of Indonesia (BMKG). Data on maize damage caused by FAW were collected from the Provincial Agriculture Service of West Sumatra, while population data were acquired through field surveys in major maize production areas. The data were analysed using correlation approaches to determine the relationship between FAW infestation intensity and monthly rainfall levels. The results revealed that FAW infestations occurred in almost all observation sites, with varying levels of damage; however, no significant correlation was found between rainfall and infestation area. This finding indicates that climatic factors, particularly rainfall, are not the main determinants of FAW outbreak dynamics in West Sumatra. Other factors, such as host plant availability, cropping patterns, and pest management practices, will likely play a more decisive role in influencing infestation intensity. These results provide important insights into the current status of FAW in West Sumatra and serve as a foundation for developing more effective and sustainable control strategies that account for complex agronomic and ecological factors.

Para-menthane-3,8-diol (PMD), derived from citronellal of citronella plants, has potential as an eco-friendly botanical insecticide for controlling Spodoptera frugiperda. This study aimed to evaluate the physiological interference caused by a PMD nanoemulsion formulation on S. frugiperda. Bioassays were conducted using the leaf-dip method. Data were analyzed using analysis of variance (ANOVA), followed by the Least Significant Difference (LSD) test with Statistix 8 and Duncan’s multiple range test at a 5% significance level using SPSS version 25. Probit analysis with POLO PLUS was performed to determine LC₂₅ and LC₅₀ values. The results showed that PMD nanoemulsion induced significant physiological interference in S. frugiperda, as indicated by increased mortality with LC₂₅ and LC₅₀ values of 0.15% and 0.48%, respectively. At a concentration of 0.75%, the treatment disrupted development by reducing pupation and adult emergence to 30% and altering the sex ratio to 1 male: 0.22 female. Sublethal interference was evident through strong antifeedant activity (62.88%) and pronounced changes in physiological parameters, including consumption rate (0.0328 mg/day), growth rate (0.0023 mg/day), and efficiency of ingested food (6.0029 mg/day). Overall, the PMD nanoemulsion formulation interfered with survival, feeding behavior, growth, and developmental physiology of S. frugiperda, highlighting its potential as an eco-friendly botanical insecticide.

The forest betel plant ( Piper aduncum. L) is one of the essential oil-producing plants. Forest betel has the potential as a raw material for botanical insecticides. Essential oils are obtained through a distillation process. This study aims to develop a method of distilling essential oils from P. aduncum fruit using a distillation device heated with firewood as one of the solutions for farmers to increase income. The test began with manufacturing a distillation device with a capacity of 30 kg. The tool is modified with a steaming and boiling system in the distillation process. The distillation equipment is tested to see the quality of the tool. The test results show that the tool is qualified to produce forest betel essential oil, with a boiler heating speed of 1 hour and 15 minutes reaching a boiling point of 100° C. Distillation can produce an essential oil yield of 0.3%. These findings support the potential for commercializing P. aduncum essential oil as a botanical insecticide and reinforce the importance of developing efficient distillation tools to optimize the production of essential oils from unutilized plant sources.

Paracoccus marginatus is one of the important pests that can reduce papaya production. Piper aduncum nanoemulsion has potential as a botanical pesticide to control papaya mealybug (Paracoccus marginatus). This present research was aimed to determine the most effective concentration in suppressing the development of P. marginatus. This study consisted of 6 treatments and 5 replications: 0.33%, 0.43%, 0.57%, 0.75%, 0.99%, and control. The observed parameters were: nymph mortality, adult mortality, daily mortality, adult emergence, LC50, and LC95. The data obtained were analyzed using variance (ANOVA) and 5% Tukey. The LC50, and LC95 value was analyzed using Polo Plus. Piper aduncum nanoemulsion exhibits strong insecticidal activity against nymphs and adults of Paracoccus marginatus under laboratory conditions. Among the concentrations tested, 0.99% was the most effective, causing 81.11% nymph mortality at 72 hours post-application; adult emergence was limited to only 13.33%. The LC₅₀ and LC₉₅ values at 72 hours were 0.506% and 1.222%, reflecting the potency of the nanoemulsion at relatively low doses. Further research under field conditions is recommended to evaluate its efficacy, formulation stability, and safety on non-target organisms.

Rice blast, caused by Magnaporthe oryzae (syn Pyricularia oryzae), remains one of the most destructive diseases of rice, resulting in severe yield losses in many rice-producing regions. Reliance on chemical fungicides has provided only partial and short-term relief, raising concerns over the development of resistance, environmental impacts, and food safety. In recent years, nanoemulsions (NEs) — fine oil-in-water or water-in-oil dispersions stabilized by surfactants — have gained attention as a practical and environmentally compatible alternative. This review consolidates recent advances in NE formulation, encompassing both high-energy and low-energy preparation techniques. Summarizes the key physicochemical parameters that influence stability and bioactivity. Special attention is given to plant-derived active compounds encapsulated in NEs, their modes of action against M. oryzae, and their performance in laboratory and field trials. The comparative advantages of NEs over conventional fungicides, their integration into rice blast management strategies, and the technical and regulatory hurdles to wider adoption are discussed. By linking efficacy with sustainability, nanoemulsion technology offers a promising route toward more resilient and eco-friendly crop protection systems.

The gambir plant can serve as a raw material for botanical insecticides. Plant-based insecticides are made in nanoemulsion form to overcome the insecticide particle size problem. This study aims to obtain a gambir waste form that has the potential to be used as a botanical insecticide using nanotechnology. The laboratory experiments include preliminary and follow-up tests. The preliminary test involves testing each extract (liquid, solid, and raw gambir waste) at three concentrations using a completely randomized design with four replications. The follow-up test uses the residue method on leaves to test insecticidal activity. Creating nanoemulsion from gambir waste involves mixing organic and liquid phases through spontaneous emulsification. The insecticidal effectiveness of this nanoemulsion is tested on Croccidolomia pavonana. The results show that solid and liquid gambir waste has the potential to be used as alternative insecticides, which can influence the mortality of C. pavonana with an LC50 concentration of 0.22 (solid waste) and 0. 29 (liquid waste), while LC95 is 2.44 (solid waste) and 2.52 (liquid waste). The research promotes utilizing natural resources and innovative technologies, advancing environmentally conscious pest control methods, and fostering sustainable agricultural systems.

Abstract. Nelly N, Hamid H, Lina EC, Yunisman, Rusli R, Yanti Y, Kairunisa M. 2024. Effectiveness of Bacillus spp. from West Sumatra, Indonesia in controlling Spodoptera frugiperda (Lepidoptera: Noctuidae). Biodiversitas 25: 1472-1478. Spodoptera frugiperda J.E. Smith (Lepidoptera: Noctuidae) is an invasive pest widely recognized for attacking corn plants. This pest was first discovered in early 2019 in West Sumatra, Indonesia, posing a significant threat to agricultural productivity. To control S. frugiperda, local biological agents, namely Bacillus spp., originating from West Sumatra, have been explored as a potential control method. Therefore, this study aimed to obtain Bacillus spp isolates from rhizosphere origin and assess their effectiveness in controlling S. frugiperda in the laboratory. A completely randomized design was used, consisting of five treatments with three replications. The treatments included Bacillus cereus strain MRPLUMBE1.3, Bacillus myocytes strain MRRZLL 2.2, and Bacillus sp. MRTE strain 1.3.3. For comparison, there was a synthetic insecticide (active ingredient chlorantraniliprole) and a control (distilled water). The application of isolate suspension was carried out through larvae feed. The parameters observed included larvae mortality, percentage of formed pupae and adults (imago), number of eggs laid by females, and survival time of adults. The data obtained were analyzed using Analysis of Variance (ANOVA) and tested with LSD at the 5% level. The results showed that Bacillus spp. isolates originating from the rhizosphere effectively controlled S. frugiperda larvae. The best isolate that can be used to control S. frugiperda is Bacillus spp. from Solok. Specifically, Bacillus sp. strain MRTPE 1.3.3 showed larvae mortality ranged between 28.33 and 41.67%, and the suspension affected the percentage of formed pupae (51.66%) and the survival time of adults (4.5-5.8 days).

Forest betel (Piper aduncum) includes weed plants from the Piperaceae family that can be used as the main ingredient in the manufacture of environmentally friendly pest control technology, also known as botanical pesticides. Botanical pesticides from P. aduncum have the active compound dillapiol, which can control pests in various plants, especially horticulture. Commercialization of botanical pesticides needs to be done because the product meets the standards for pest control and is available in sufficient quantities on the market. The partnership was initiated by involving local communities as providers of raw materials. Surian area, Solok Regency, West Sumatra, Indonesia, has an area where P. aduncum plants dominate, so it has the potential to provide raw materials. Socialization activities about the potential of forest betel fruit or P. aduncum were given to prospective partner communities. Furthermore, training activities on handling P. aduncum fruit were also provided so that partners had sufficient knowledge and skills to proceed. At the same time, an analysis of P. aduncum fruit extract from the Surian area was also carried out. Sampling was carried out in the Surian area, and then the material was sorted, dried, refined, sieved, maserase, and extracted. Identification of dillapiol content was carried out using GC-MS. The analysis results showed that P. aduncum fruit extract was known to have an average yield of 0.1% with a dillapiol content of 12.23% at a retention time of 19.925 minutes.

The discovery of active compounds such as citronellol, citronellal, and geraniol in citronella grass (Cymbopogon nardus) opens new opportunities for using essential oils derived from this plant. These compounds are well-known for their aromatic properties and various benefits in the derivative product industry. Combining these three compounds presents immense potential for developing high-quality products such as soaps, aromatherapy, and pesticides. Community engagement activities were conducted in Cibarani Village, Lebak Regency, Banten. The fertile land in Cibarani Village is well-suited for cultivating citronella grass (C. nardus). The activities began with outreach and training sessions to educate the local community on the potential of C. nardus essential oil. This initiative aimed to equip the community with adequate knowledge and skills to process C. nardus oil into various derivative products. The derivative products introduced included botanical pesticides for controlling pests in cultivated plants. This information is particularly beneficial for the Mekar Rahayu Farmers Group, enhancing their knowledge and understanding of the potential of C. nardus essential oil as a botanical pesticide. It is hoped that the community will be able to produce botanical pesticides for personal use and sale to other farmers, thereby increasing their income. Simultaneously, the team also collected samples of citronella grass from Cibarani Village for distillation. The C. nardus oil obtained was analyzed using Gas Chromatography-Mass Spectrometry (GC-MS) to identify the dominant compounds. The essential oil produced from citronella grass in Cibarani Village, based on GC-MS results, revealed the main components as geraniol at 25.53% with a retention time of 13.212 minutes, citronellol at 15.71% with a retention time of 12.694 minutes, and citronellal at 17.19% with a retention time of 11.422 minutes.
