Abstract

Etiella zinckenella is a significant pest of peanuts in Indonesia, causing pod yield losses of up to 100% in infested fields. This study aims to identify an appropriate strategy for the sustainable management of E. zinckenella by validating the effectiveness of various integrated pest management approaches through field trials. The experiment was conducted in two locations, Natar (Lampung) and Muneng (East Java), using 11 treatment combinations with three replications. The peanut variety planted was Gajah (GH 51). The treatments included a range of pest control technologies, such as seed treatment with thiamethoxam, application of carbofuran, neem seed powder (NSP), release of Trichogrammatoidea bactrae-bactrae, application of Spodoptera litura Nuclear Polyhedrosis Virus (SlNPV), trap crops (Crotalaria, soybean, maize, mung bean), organic fertilizer, and lambda-cyhalothrin. The findings revealed that the population density of pod borers and the extent of pod and seed damage were higher in Natar than in Muneng. In Natar, pod damage ranged from 43.7% to 76.3%, with the highest levels recorded in untreated plots and those treated with lambda-cyhalothrin. Similarly, the highest pest population densities in Natar were observed in untreated plots and those treated with lambda-cyhalothrin. In contrast, Muneng exhibited significantly lower pod damage, ranging from 0.2% to 2.6%, with the highest recorded damage at 2.64%. The most effective pest management strategy in both locations was a combination of thiamethoxam seed treatment, carbofuran, NSP, T. bactrae-bactrae, SlNPV, and Crotalaria trap crops, which reduced pod damage to 43.7% in Natar and 0.2% in Muneng. These results suggest that an integrated pest management approach effectively mitigates E. zinckenella infestations in endemic areas. This method not only minimizes pest damage but also helps maintain populations of natural enemies, including Formicidae, Coccinella sp., Paederus sp., and Oxyopes sp., thereby supporting ecological balance. Furthermore, trap crops such as maize, soybean, and mung bean, when planted around peanut fields, demonstrated considerable efficacy in reducing pest attacks compared relative to chemical insecticides, highlighting their potential for a sustainable pest management strategy.

Abstract

Spodoptera litura Nucleopolyhedrovirus (SpltNPV) is an entomopathogenic virus from the Baculoviridae family, currently under development as a biological control agent for cutworm Spodoptera litura. The NPV’s ability to infect its pest host can be determined by expression of pif protein complex by pif gene. The research aims to acquire genetic character information of the pif gene of SpltNPV from Bogor. Amplification of the NPV gene was carried out using the specific primers to amplifies two types of pif gene. The PCR products were sequenced then the DNA sequences were analyzed with the BioEdit and BLAST programs. The PCR amplification results showed that the size of the sample DNA fragment was 900 bp, 1300 bp and 710 bp. Based on the sequence analysis results, SpltNPV isolates from Bogor are closely related to SpltNPV and SpliNPV isolates from China. The highest nucleotide homology values of Pif-1, Pif-2, and Pif-3 gene were 99.56%, 99.37% and 100%, respectively. Based on the results of phylogenetic analysis, HearNPV isolates from Bogor belong to the same group as the NPVs that infect the species Spodoptera litura and closely related to NPV that infect Spodoptera littoralis. The amino acid sequence analysis showed the number of mutated sites in pif-1, pif-2, and pif-3 in this study are 1, 3, and 0, respectively, which indicates that protein mutation in SpltNPV Bogor did not significantly alter the viral infection process.

Abstract

The research aimed to (i) isolate, select, and assess the pathogenic potential of fungi that pose a risk of causing scab disease on King mandarin fruits (Citrus sinensis), and (ii) evaluate the antagonistic potential of Trichoderma spp. against Neurospora spp., , which cause scab disease on King mandarin fruits under in vitro conditions. The isolation process identified four fungal strains from ten King mandarin fruits showing scab symptoms, collected from ten orchards in Vung Liem District, Vinh Long Province. The three most virulent scab-causing fungal strains were KMS-01, KMS-02, and KMS-04, with growth diameters of 7.60–7.63 cm after 72 hours of culture (HoC). Additionally, the antagonistic ability of 50 Trichoderma spp. strains against Neurospora spp. ranged from 49.8% to 87.6% at 72 HoC. Among these, three Trichoderma spp. strains—T-SP03, T-SP26, and T-SP41—exhibited high antagonistic efficiency (86.1%–87.7%) against all three scab-causing strains. Based on the ITS region, the pathogenic fungal strains were identified as Neurospora intermedia KMS-01, N. intermedia KMS-02, and N. crassa KMS-04, while the Trichoderma spp. strains were identified as Trichoderma asperellum T-SP03, T-SP26, and T-SP41 with 100% similarity. T. asperellum shows potential as a biological control agent against Neurospora spp., the causative agents of scab disease in King mandarin.

Abstract

The antiviral activity of leaf extracts from Datura stramonium and tomato plants inoculated with TMV, combined with 20% skimmed milk, was investigated. A TMV isolate was confirmed using bioassay, serological, and molecular approaches and subsequently used to inoculate plants. Tomato plants, both pre- and post-inoculated with TMV, were sprayed with leaf extracts from either TMV-free or infected plants, alone or mixed with 20% skimmed milk. Enzyme-linked immunosorbent assay (ELISA) using tobamovirus-specific antibodies and local lesion tests were conducted to assess antiviral activity based on virus concentration and infectivity in treated plants. The experiment followed a completely randomized design (CRD), and the Least Significant Difference (LSD) test was applied to evaluate ELISA optical density (OD) values. OD data revealed that the combination treatment (inoculated tomato leaf extract + 20% skimmed milk) inhibited TMV in tomato plants by up to 56%, showing the highest antiviral activity. This study is the first to investigate the antiviral potential of leaf extracts from TMV-infected plants.

Abstract

Whip smut symptoms have emerged in sugarcane plantations in Central Lampung Regency, Lampung Province. However, the identity of the pathogen and its sensitivity to various fungicidal active ingredients remain unclear. This study aims to identify the whip smut pathogen in sugarcane plantations in Central Lampung Regency and evaluate its sensitivity to different fungicidal active ingredients.The research involved morphological and molecular identification of the pathogen, along with sensitivity testing against fungicides containing carbendazim, prochloraz, and mancozeb, as well as plant-based fungicides derived from puyangan (Zingiber zerumbet) and jamuan (Curcuma zedoaria) extracts. Morphological analysis revealed that the whip smut pathogen has septate hyphae, cylindrical sporidia measuring 7.45–18.31 µm in length and 1.63–3.89 µm in width, and round, yellowish-brown teliospores with an average size of 6.39 × 6.66 µm. Molecular identification confirmed that the LA UKN isolate from Central Lampung Regency belongs to Sporisorium scitamineum, with a bootstrap value of 93%. Sensitivity testing indicated that the pathogen is highly susceptible to carbendazim and prochloraz but less sensitive to mancozeb, puyangan extract, and jamuan extract.

Abstract

Birds are among the most significant vertebrate pests affecting sorghum crops worldwide, particularly in community farming systems. Their attacks can lead to substantial yield losses, especially during the grain ripening stage. This study aimed to identify the species, number of individuals, attack frequency, extent of crop damage, and control efforts related to bird pests in sorghum cultivation. The research was conducted from December 2022 to February 2023 in Karangmojo Village, Gunungkidul Regency, Yogyakarta, Indonesia. Six sorghum genotypes were planted: bioguma (V1), plonco (V3), samurai (V4), kawali (V6), hitam wareng (V8), and ketan merah (V9). However, observations were focused on bioguma and plonco, which experienced the most bird attacks. Three seed-eating bird species were identified: Geopelia striata (kutut, 156 individuals), Lonchura leucogastroides (bondol jawa or emprit, 375 individuals), and Spilopelia chinensis (derkuku or tekukur, 329 individuals). The peak bird activity occurred in the morning, with 47 attack events recorded in bioguma and 35 in plonco. The average crop damage reached 1.26% in bioguma and 1.24% in plonco, resulting in estimated yield losses of Rp. 922,140.00 and Rp. 750,360.00 per ha, respectively. Control measures employed by farmers included the use of perforated plastic hoods and safety nets, though their effectiveness was limited.

Abstract

Sari intan is a superior variety of snake fruit developed in Bintan District, Riau Islands, in 2015. The pests and diseases that attack the Sari Intan variety are not yet known. This research was conducted to analyze and identify potential pests and diseases affecting Sari Intan snake fruit at different plant ages in Bintan Regency. A survey was conducted in nurseries and in plantations with two- and five-year-old plant populations. Insects found were collected and identified in the laboratory. Plant parts showing disease symptoms were also collected; the pathogens were identified, and the intensity of damage was measured. Data were processed using Microsoft Office Excel 2010 and described qualitatively. The results showed that potential insect pests included Iceria sp. (Hemiptera: Monophlebidae), Coccotrypes sp. (Coleoptera: Curculionidae), and Setothosea asigna (Lepidoptera: Limacodidae). A non-insect pest observed was Zonitoides arboreus (Stylommatophora: Gastrodontidae). The incidence of disease in Sari Intan snake fruit leaves reached 100%, with a damage intensity of 58,7%, caused by fungal infections. The fungi identified were Pestalotia sp., Colletotrichum sp., Helminthosporium sp., Fusarium sp., and Curvularia sp. An important postharvest disease was fruit rot, caused by Thielaviopsis paradoxa.

Abstract

The cocoa pod borer (CPB), Conopomorpha cramerella Snellen, is one of the most significant pests of cocoa, capable of damaging pods and reducing production. Synthetic insecticides are predominantly used to control this pest; therefore, alternative methods that are environmentally friendly and do not harm non-target organisms are needed. This study aims to determine the role of beneficial insect occurrence, enhanced by insectary plants, in reducing the severity of pod damage and yield loss caused by CPB. The research was conducted by comparing two one-hectare farms, one with and one without insectary plants. The beneficial insects observed included pollinators, predators, parasitoids, decomposers, and herbivores. Their populations were higher on the farm with insectary plants than on the farm without, with pod damage severity of 16.8% and 32.8%, respectively. These data indicate that cultivating insectary plants on cocoa farms can aid in pest management, particularly for CPB, and has the potential to be implemented on a larger scale, as CPB attack intensity was lower on the farm with insectary plants.

Abstract

The mealybug Maconellicoccus multipori (Takahashi) was identified on black pepper (Piper nigrum L.) seedlings in a greenhouse in Bogor, West Java, using both molecular and morphological characterization. Two mealybug isolates were successfully amplified with primer pairs targeting the LCO region of the mitochondrial cytochrome oxidase I (COI) gene, yielding a 491 bp PCR product. The nucleotide sequences of both isolates (GenBank accession numbers LC666906 and LC666907) were identical. Phylogenetic analysis revealed that the Bogor isolates clustered closely with M. multipori populations from China and Thailand, with high sequence homology of 99.30% and 99.10%, respectively. Morphological observations of the adult female specimens further confirmed their identity as M. multipori, based on key diagnostic features including body size, antennal segmentation, cerarii pattern, and distribution of pores and ducts, which correspond to descriptions in established taxonomic keys. This study provides the first molecular characterization of M. multipori in Indonesia. The COI sequence data obtained enhances reference databases for DNA barcoding and strengthens early detection strategies for pest monitoring. These findings are crucial for supporting quarantine inspections, management, and control of M. multipori in black pepper nurseries and preventing its spread to other crops.

Abstract

Plant growth-promoting bacteria are well known as biostimulants, biofertilizers, bioprotectants, and biodegraders. The Pulang Pisau Food Estate is an Indonesian government program aimed at increasing rice crop production to achieve sustainable food self-sufficiency. Research on rhizobacteria in the Pulang Pisau Food Estate area is still relatively limited. In this study, we conducted in vitro assays to evaluate the potential of indigenous bacterial isolates from the Pulang Pisau Food Estate as plant growth-promoting rhizobacteria (PGPR). The study focused on four bacterial isolates, which were tested for plant growth-promoting traits including phosphate solubilization, indole-3-acetic acid (IAA) production, effects on rice seed germination, and detached leaf assays to assess the ability of rhizobacteria to inhibit bacterial pathogens. The results of 16S rRNA gene identification suggested that isolates UNS-P1, UNS-P3, and UNS-R1 were closely related to Bacillus cereus, while one previously identified isolate (UNS-R2) was confirmed as Bacillus subtilis. All bacterial strains were able to produce IAA, while only one isolate demonstrated the ability to solubilize phosphate. In the germination test, no significant differences were observed in root length, but a significant difference in shoot (plant) height was detected. Bacillus subtilis (UNS-R2), at a 10³ dilution, resulted in significantly greater plant height compared to other treatments. Among the four bacterial isolates, only one showed the ability to inhibit the pathogen Pantoea ananatis. These results suggest that indigenous bacterial isolates from the Pulang Pisau Food Estate have potential as plant growth-promoting rhizobacteria (PGPR) and may contribute to enhancing plant growth and serve as biocontrol agents against P. ananatis.
