Spodoptera frugiperda is an important pest that is dangerous for maize originating from America. In 2019 this pest was reported to have entered Indonesia and attacked maize plants in the Sumatra area. The larvae of S. frugiperda can eat quite a lot of the cobs and leaves of young corn and even run out, causing the corn to experience a decline and even a significant loss of yield. Biological con…
In Indonesia, tomato plant is one of a few coveted plants because it includes one that has many health benefits. The tomato plant is also widely cultivated by farmers or the common people as an everyday food item. This tomato plant is a virulent fusarium caused by the fusarium oxysporum. Non-damaging replacement control is with the use of biological agents. The matter of this study is how the i…
Spodoptera frugiperda is a South and North American invasive pest that has spread and entered the Asian continent. The spread is rapid and poses a threat to food security, particularly maize. Pest control using endophytic entomopathogenic fungi is the best way to control S. frugiperda, and endophytic fungi also have a positive impact on plant growth. This control has not been applied widely. Th…
Endophytic microorganisms are microorganisms that are located on the inside of higher plant tissues, so they do not cause intracellular or intercellular growth in the host. Endophytic microorganisms are classified as one of the plant symbiont groups, this makes them a component of microbial diversity. The endophytic phylum of fungi of various plant species includes: Ascomycota, Basidiomycota, a…
Oil palm (Elaeis guineensis Jacq.) is one of the important industrial crops and plays a role in national development. Stem rot disease caused by the fungus G. boninense is a major problem in oil palm cultivation in Southeast Asia. The fungus Trichoderma pseudokoningii is a type of fungus that has been widely tested as an antagonist funguson several pathogenic fungi including G. boninense which …
Spodoptera frugiperda is an important pest for corn plants which can cause high losses and become a problem in maize agriculture in the world. S. frugiperda attacks maize in the generative and vegetative phases which can be detrimental economically. One good control in reducing the population of S. frugiperda is to use entomopathogenic fungi. Entomopathogenic fungi can be used as larvicides tha…
Spodoptera frugiperda is a cosmopolitan polyphagous pest that attacks various plants in Indonesia, both in the vegetative and generative phases. Spodoptera frugiperda has as many as 353 host plants from 76 families. Control by utilizing entomopathogenic fungi is one of the efforts made to suppress this pest attack, besides that it is also useful as a plant growth promoter. Therefore, this study…
Red chili (Capsicum annuum L) is one of the most widely cultivated commodities in Indonesia. One of the diseases that often attack chili plants is anthracnose which is caused by a fungus from the genus Colletotrichum. Generally, the species that attack chili plants come from Colletotrichum capsici and Colletotrichum acutatum. This research was carried out at the phytopathology laboratory in Aug…
Bees are insects that are very important for agricultural pollination and direct human needs. Diseases in stingless bees have been reported, including Deformed wing virus (DWV), chalkbrood, and Aspergillus spp. attacks. Stingless bees have also been reported to have several cases of disease, including Acute bee paralysis virus (ABPV), Deformed wing virus (DWV), and broodcell by the bacterium Ly…
Spodoptera frugiperda J.E. Smith (Lepidoptera: Noctuidae) is a major pest of corn originating from America and spreading rapidly to several countries such as Africa. Damage caused by S. frugiperda can be detrimental to farmers economically. The total loss of corn production in Indonesia reached 18 million tonnes/year. Corn farmers tend to use synthetic pesticides to control S. frugiperda, but t…
