Abstract

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

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.

Abstract

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.

Abstract

A nanoemulsion formulation of a mixture of Piper aduncum extract and Cymbopogon nardus hydrosol was evaluated for its effectiveness against the major broccoli pests, Crocidolomia pavonana and Plutella xylostella. The study was conducted in Alahan Panjang, West Sumatra, using a completely randomized design with four treatments (the nanoemulsion formulation, Bacillus thuringiensis, cypermethrin, and a control) and seven replications. Treatments were applied weekly from 21 to 70 days after planting (DAP). Larval population density and plant damage were recorded, and the data were analyzed using analysis of variance (ANOVA) followed by a least significant difference (LSD) test at a 5% significance level. Infestation by P. xylostella occurred earlier at 21 DAP, whereas infestation by C. pavonana began at 28 DAP. Overall, the population density of P. xylostella was higher than that of C. pavonana. The nanoemulsion formulation exhibited insecticidal activity, although its effectiveness was lower than that of cypermethrin and B. thuringiensis. The effectiveness rates against C. pavonana were 71.49%, 48.54%, 33.33%, and against P. xylostella were 73.49%, 60.88%, and 57.52% for cypermethrin, B. thuringiensis, and the nanoemulsion formulation, respectively.

Abstract

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.

Abstract

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.
