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.

Abstract

The use of resistant rice varieties remains a key component in managing the brown planthopper (BPH), Nilaparvata lugens Stål (Hemiptera: Delphacidae). However, information on the resistance of indigenous rice varieties from South Pesisir Regency, West Sumatra Province, Indonesia, is still limited. This study aimed to evaluate the resistance levels of several local rice varieties from South Pesisir Regency to BPH. The experiment was conducted under laboratory conditions using a completely randomized design with seven treatments and four replications. The treatments consisted of five local rice varieties (Sarai Sarumpun, Kutu, Bakwan, Banang Salai, and Bujang Marantau), with TN1 and IR74 used as susceptible and resistant controls, respectively. Seven-day-old rice seedlings were infested with second–third instar BPH nymphs. Variables observed included BPH attack symptoms, mortality, attack percentage, and attack intensity. The results showed significant variation in resistance among the tested varieties. Banang Salai exhibited the highest resistance, with 83.13% BPH mortality, 68.75% attack percentage, and 50.34% attack intensity, indicating a resistant response. In contrast, Sarai Sarumpun showed the lowest resistance, with only 25.94% BPH mortality and the highest attack intensity (90.52%), and was classified as highly susceptible. These findings demonstrate that Banang Salai is a promising local genetic resource for BPH resistance, highlighting the potential of indigenous rice varieties to support sustainable pest management.

Abstract

Altitudinal gradients strongly influence the distribution and abundance of insect pests by affecting microclimate, host availability, and cropping intensity. Bactrocera dorsalis (Hendel) is a major constraint to red chili (Capsicum annuum L.) production in Indonesia; however, empirical evidence linking altitude to its field abundance in Sumatra has not been fully elucidated. This study quantified the association between altitude and the abundance patterns of B. dorsalis using field data collected from 33 chili-growing sites across four regencies of West Sumatra, Indonesia, spanning elevations from <15 to 1,571 m above sea level, during the rainy season (October 2024-March 2025). Adult flies were monitored using methyl eugenol-baited modified Lynfield traps. Catch data were analyzed across altitudinal zones using ANOVA, correlation, and linear regression. Trap catches differed significantly among elevation categories (p< 0.05), with higher mean abundance generally recorded in pre-montane sites (>600 m) than in lowland sites (<600 m). Regression analysis indicated a positive association between altitude and trap catches (r = 0.391, p = 0.024), with altitude explaining 15.3% of the variation in abundance (R2 = 0.153), and linear regression indicated a moderate increase in captures with increasing elevation (B = 0.103). K-means clustering of regencies based on mean elevation and total trap catches further separated Solok as a distinct group characterized by higher abundance. These findings demonstrate spatial structuring of B. dorsalis abundance across elevation zones and support the incorporation of elevation-informed surveillance into fruit fly monitoring programs in West Sumatra.

Abstract

Petani sangat mengandalkan insektisida sintetik dalam upaya pengendalian hama. Penggunaan insektisida sintetik yang tidak bijaksana dapat menyebabkan kerusakan lingkungan yang ditandai dengan musnahnya mikro organisme tanah, matinya musuh alami, dan matinya organisme bukan sasaran lainnya. Selain itu dampak negatif residu pestisida pada produk pertanian dapat menyebabkan gangguan kesehatan pada manusia yang mengkonsumsi produk yang terkontaminasi residu pestisida. Pengendalian hama alternatif yang ramah lingkungan sangat dibutuhkan dalam proses budidaya tanaman, diantaranya adalah insektisida botani. Upaya mengurangi ketergantungan petani terhadap insektisida sintetik dapat dilakukan dengan menjadikan petani sebagai produsen insektisida dan bukan hanya sebagai konsumen. Insektisida botani dari bahan tumbuhan yang ada di sekitar tempat bercocok tanam dapat digunakan sebagai tindakan pencegahan (preventif) dari serangan hama. Piper aduncum atau yang disebut sirih hutan dan Tephrosia vogelii atau disebut kacang babi banyak ditemukan di lahan pertanian produktif Alahan Panjang, Sumatera Barat. Campuran dua jenis bahan ini dengan perbandingan 2:1 diketahui dapat mengendalikan hama dari golongan Lepidoptera yang menyerang sayuran. Sosialisasi penggunaan di tingkat petani, latihan penyiapan bahan tanaman dan pembuatan larutan semprot dengan konsentrasi 5%, perlu dilakukan agar pengendalian hama efektif dan efisien. Manfaat kegiatan ini dapat membantu petani dalam mengendalikan serangan hama pada tanaman budidaya, mengurangi penggunaan insektisida sintetik, menghemat biaya produksi dan secara tidak langsung meningkatkan pendapatan petani.

Syahrawati M, Nelly N, Hamid H, Efendi S. 2018. Short Communication: Abundance of corn planthopper (Stenocranus pacificus Kirkaldy 1907, Hemiptera: Delphacidae) on five new corn varieties. Biodiversitas 19: 1029-1034. Both local and hybrid corn varieties have been attacked by Stenocranus pacificus or corn planthopper frequently grown in West Sumatra. So, the basic aim of the study is to know about the abundance of S. pacificus on major five corn varieties that will be intermittently released viz., N35, N37, NT10, NT104, and NT105. The study was conducted around palm plantation in Dharmasraya District using Randomized Block Design in 5 replications. The observations were made at weekly intervals throughout the season after planting up to 8 weeks. Number of S. pacificus were collected from 16 hills by using simple aspirator, selected randomly from each unit. The measurement of leaf length, leaf width, stem diameter and trichome length were also performed to confirm the physical effect of S. pacificus preferences. LSD test at 5% level of significance was done to determine the influence of different varieties on insect population. The S. pacificus preferably effect to NT10 variety as compared to other varieties from the early growth of corn, but the S. pacificus abundance was higher at the generative phase than the vegetative. There was a very rapid increase in its population from week to week. Physical factors of the plant, as like as trichome, affected the insect abundance.

Diversity and characterization of entomopathogenic fungi from rhizosphere of maize plants as potential biological control agents. Biodiversitas 20: 1435-1441. The diversity and characters of entomopathogenic fungi in soil are influenced by cultivation techniques. This study aims at determining the characters and pathogenicity of entomopathogenic fungi in maize plant. Materials were extracted from maize plant rhizosphere at different planting system (monoculture, polyculture, and monoculture of corn on formerly oil palm plantation or replanting) in Nagari Koto Baru, Luhak Nan Duo Subdistrict, West Pasaman District, and West Sumatra Province. Insect bait and series dilution were used to carry out the isolation, while Tenebrio molitor larvae were used for the pathogenicity test. Parameters observed include macroscopic and microscopic characteristics, and pathogenicity of entomopathogenic fungi. The result shows that there are three types of entomopathogenic fungi with various features. After identification, it was known that Aspergillus and Metarizium were obtained from mono, polyculture and by replanting crops, while Beauveria was found from the rhizosphere of corn grown in polyculture with pathogenicity identified as one of the high causes of death to larvae T. molitor with LT50 ranging from 48.03-48.48 hours.

Abstract. Nelly N, Khairul U, Putri AY, Hamid H, Syahrawati MY. 2020. Isolation and selection of maize plants rhizobacteria with the potential of entomopathogens against Spodoptera litura F (Lepidoptera: Noctuidae). Biodiversitas 21: 753-758. &nbsp;Spodoptera litura is a polyphagous pest that can be controlled with entomopathogen. Furthermore, Rhizobacteria derived from the rhizosphere of corn plants are expected to control this pest. This research, therefore, was conducted to obtain the entomopathogenic rhizobacteria to control S. litura derived from the rhizosphere of corn plants. Data sampling was carried out at corn plantations in West Pasaman Regency, while Isolation, selection, and testing of S. litura were conducted at the Biological Control Laboratory of the Plant Protection Department, Faculty of Agriculture, Andalas University. The method uses serial glowing techniques cultured on Nutrient Agar (NA) media, with the selected isolates tested for their ability as an entomopathogen against S. litura. The feed dip method given to S. litura larvae was used to test for rhizobacteria virulence determination with entomopathogen, used to observe the larvae mortality rate, percentage of pupae, and adult formed. Furthermore, observation of morphological and physiological characters was conducted on entomopathogenic rhizobacteria, with hypersensitive testing conducted on Mirabilis jalapa plants. The results of rhizobacterial isolation from corn rhizosphere obtained 12 entomopathogenic isolates. Deadly larvae of S. litura 51-91.11%, 0.00-8.89% pupae, and 0.00- 6.67% adult were formed. The gram test results obtained approximately 8;4 positive (+) and four negative isolates (-), respectively. Hypersensitivity test results found that one of 12 isolates caused necrotic reactions in Mirabilis jalapa. Therefore, a total of 11 rhizobacteria isolates are entomopathogenic and safe to be used as S. litura biological control agents.
