Perhatian terhadap potensi cendawan sebagai penginduksi ketahanan tanaman telah mengalami peningkatan dalam beberapa tahun terakhir. Cendawan entomopatogen berperan sebagai pengontrol populasi serangga hama dengan menghasilkan metabolit sekunder berupa enzim dan toksin, serta mampu hidup secara endofit didalam jaringan tanaman dan mempengaruhi morfologis dan fisiologis tanaman. Keberadaan cendawan entomopatogen secara endofit mampu menginduksi ketahanan tanaman dengan merangsang terjadinya peningkatan fitohormon tanaman. Artikel ini bertujuan untuk mengulas peranan cendawan sebagai entomopatogen, karakterisasi cendawan sebagai entomopatogen serta peranan cendawan entomopatogen sebagai penginduksi ketahanan tanaman. Dari hasil review diketahui bahwa peranan cendawan entomopatogen sebagai penginduksi ketahanan tanaman merupakan alternative pengendalian yang sangat menjanjikan dalam perkembangan management perlindungan tanaman terhadap serangga hama

IInsect pathologists' attention to the potential of entomopathogenic fungi (EPF) as inducers of plant resistance has increased in recent years. Several types of EPF that have received attention as biocontrol agents for insect pest populations include Beauveria bassiana, Metarhizium anisopliae and Trichoderma sp. because they are able to infect and kill insects directly, has a wide host range, and has been used to control various types of insect pests. Apart from being able to infect and kill insect pests, EPF can also live endophytically in plant tissue and increase plant resistance to pest attacks. The presence of EPF as endophytes is able to induce plant resistance by stimulating an increase phytohormones production. In this article, we reviewed the role of fungi as entomopathogens, the characteristics of entomopathogenic fungi, and their role as inducers of plant resistance. The review was carried out by collecting information from original articles and related reports which reviewed the results of research on the role of entomopathogenic fungi as plant resistance inducers by including the keywords entomopathogenic endophytic fungi, resistance induction, characterization, systemic resistance and herbivorous insects. This systematic review concludes that EPF as an inducer of plant resistance is a very promising control alternative in the development of plant protection management against insect pests.

Entomopathogenic mushrooms (CEPs) double function as biocontrol agents against pests and as biostimulants that support plant growth through the production of hormones such as IAA and gibberelline. The application of CEP as a biostimulant can be done through seed treatment, with effectiveness greatly influenced by the type of mushroom and the duration of soaking. This study aims to evaluate the effect of the length of seed soaking in CEP suspension on germination, vigor index, and early plant growth. The three types of CEP used are Beauveria bassiana, Metarhizium anisopliae, and Trichoderma asperellum. Corn seeds are soaked in a conidia solution with a concentration of 1 × 10⁸ conidia/ml and sterile aqueducts for 3, 6, 12, and 24 hours. Observations were made on the percentage of sprouts (day 7), vigor index (day 12), and seedling growth (day 28). The results showed that soaking the seeds in CEP suspension was able to improve all growth parameters. Of the four durations tested, soaking for six hours gave the most optimal results in increasing germination, vigor, and early growth of corn plants.

This study aims to explore and select endophytic fungi from oil palm plants (Elaeis guineensis Jacq) which have the potential to be entomopathogenic to insect pests. Endophytic fungi are microorganisms that live in plant tissues without causing symptoms of disease, but some species are known to be able to infect insects and act as biological control agents. The research was carried out through the isolation of mushrooms from healthy oil palm roots, stems, and leaves obtained from PTPN III Silau Dunia's plantation, North Sumatra. A total of 120 isolates were successfully identified from 8 genera, with Fusarium oxysporum being the dominant species. Pathogenicity tests on Tenebrio molitor larvae showed that some isolates had high entomopathogenic activity, with mortality rates reaching 90% at concentrations of 20 × 10⁶ conidia/mL. These results suggest that endophytic fungi have great potential as a natural bioinsecticide in oil palm pest control. The use of biological agents is expected to be an effective and environmentally friendly alternative in supporting sustainable agricultural systems.

Oil palm (Elaeis guineensis Jacq) is a strategic plantation commodity in Indonesia that plays an important role in the national economy. However, the productivity of these plants is often hampered by pest attacks such as fireworms (Setora nitens) and horn beetles (Oryctes rhinoceros). So far, pest control has relied more on synthetic pesticides that have a negative impact on the environment and health. This study aims to explore the potential of local entomopathogenic fungi from oil palm rhizosphere soils as biological agents for pest control. The research was carried out through the stages of isolation, morphological characterization, and bioassay tests on Tenebrio molitor larvae. The results showed six mushroom isolates, namely Aspergillus sp., Beauveria sp., and Trichoderma sp. From the bioassay test, three isolates were pathogenic to the larvae, with the isolate Beauveria sp. (CRT 03) showed the highest mortality of 85%, LT₅₀ for 4.26 days, and mycosis 55.88%. These results show that Beauveria sp. CRT 03 has high potential as a local bioinsecticide. This research supports the development of sustainable pest control in oil palm plantations through the use of environmentally friendly biological agents.

Pathogens that cause plant diseases do not only attack when it was in the field until harvesting, these attacks continue until the agricultural product was stored and consumed. The agricultural products could be stored for a long period after harvesting. During storage, there were several constraints were found in the form of decreased quality due to postharvest disease which it was caused by several pathogens such as fungi, bacteria, and viruses. Fungi were a group of pathogens that were often found as a cause of postharvest disease in agricultural commodities. The method used in this study was a blotter, then it would be continued by isolation and purification and also identification of the pathogen under a microscope. The results of the identification of fungi that cause postharvest diseases in corn and peanut seeds were found in four pathogenic fungi, namely Aspergillus niger, Aspergillus flavus, Penicillium sp, and Fusarium sp.

Crocidolomia pavonana is a significant pest on cabbage that reduces the quality and quantity of cabbage. Utilizing microorganisms such as rhizobacteria is an alternative environmentally friendly control that can potentially suppress the development of this pest. The study aimed to obtain rhizobacteria isolates capable of colonizing cabbage tissue and inducing plant resistance to C. pavonana larvae. The research was conducted at the Biological Control Laboratory and Greenhouse, Faculty of Agriculture, Universitas Andalas, Padang. The study used a Completely Randomized Design (CRD) with ten treatments and five replications. The treatment consisted of rhizobacteria isolates, including Bacillus thuringiensis, Bacillus subtilis, Serratia marcescens, Stenotrophomonas maltophilia, as well as a negative control (aquadest sterile) and a positive control (Cypermethrin insecticide). The test was carried out by soaking the seeds in a suspension containing rhizobacteria with a population density of 10⁸ cells/ml. The variables observed were larval mortality, pupa and imago formation percentage, and increased salicylic acid production. The data were analyzed using variance and continued with the LSD further test at the 5% level. The results showed that all rhizobacteria isolates colonized into cabbage plant tissue could kill C. pavonana larvae and inhibit these insects' biological development. B. thuringiensis KJKB7.3 showed better results with the highest mortality value (62.67%). Soaking cabbage seeds with rhizobacteria can increase the content of salicylic acid. Based on this research, the rhizobacteria used in the research have the potential to be developed as biological agents to control C. pavonana.
